The first floating nuclear power plant to 2016 year

During the exhibition last week, the International Naval Salon 2013, officials of the Russian United Shipbuilding Corporation announced several Newsconcerning the latest industry achievements and ongoing projects. So, the management of the Baltic Shipyard (St. Petersburg) shared information on the progress of one of the most daring projects of recent times - the construction of the Akademik Lomonosov floating nuclear power plant (FNPP).

As the director of the Baltzavod, A. Voznesensky, said, the first domestic floating nuclear thermal power plant will be built by the 2016 year. At present, the ship’s structures are being installed and in three years Rosatom will receive the world's first floating nuclear power plant. The vessel will be able to provide electricity and heat to the city and enterprises in remote areas of the country, primarily in the Far North. Shortly after the construction of the first floating power plant is completed, it is planned to begin construction of the following vessels of this series.

The construction of the first vessel with nuclear power plant units on board is underway. Employees of the Baltic plant assemble metal structures and install equipment. Work has begun on the installation of some elements of the reactors. Thus, the construction project of the Akademik Lomonosov FNPP has finally got off the ground. Recall the construction of a ship with a nuclear energy module began in 2007, at the Severodvinsk plant Sevmash. However, a few months after the start of construction, all the assembled units of the future floating power plant were transferred to the Baltiysky Zavod, where it was supposed to continue work. However, such plans did not materialize and the construction was frozen for several years. The current work is carried out in accordance with the new agreement between Rosatom and Baltzavod, signed in December last year.

Ready floating nuclear power plant “Akademik Lomonosov” will be a non-self-propelled vessel with a displacement of more than 21 thousand tons. The absence of its own power plant due to the peculiarities of the operation of FNPP. It is assumed that the tugs will bring it to the place of work, after which the vessel in the port will connect to the communications of the supplied object and will provide it with heat and electricity for a specified period. The crew of FNPP from 69 man will control the operation of two nuclear reactors capable of generating up to 70 MW of electricity and 300 MW of heat. If necessary, the power plant will be able to work as a desalter of sea water. In this mode, the estimated maximum capacity of the Akademik Lomonosov floating nuclear power plant is 240 thousand cubic meters of fresh water per hour. According to official data from the project developers, such characteristics will allow one floating power plant to supply electricity and heat to a city with a population of up to 200 thousand people.

The stated life of one FAPP is 40 years. After this time, a vessel with a nuclear power plant is planned to be towed to the appropriate enterprise to replace the power unit that has spent its life. In its place is supposed to install a new unit, after which the floating power plant can be returned to the old duty station or transferred to a new one.

Developers and builders of the first floating nuclear power plant - Iceberg Central Design Bureau, OKBM them. I.I. Afrikantova and Baltiysky Zavod - emphasize that in the construction of the vessel and the nuclear power plant, groundwork has been used that has been tested in northern conditions for many decades. The project of the APEC “Akademik Lomonosov” laid a safety margin that far exceeds all possible threats, including tsunamis, collisions with other ships or coastal installations, etc. similar disasters. The safety level of nuclear power plants of new FAPES fully meets all international requirements for such equipment.

Due to the remoteness of such events, it is not yet known exactly where exactly the first Russian floating nuclear power plant will go. Earlier, during the start of construction of the lead ship, it was claimed that such power stations would serve in the Far East and the Far North. Chukotka Autonomous Okrug, Taimyr and Kamchatka were indicated as possible jobs. Perhaps in the future such a list of territories in need of supply with the help of floating power plants will undergo major changes. It is noteworthy that not only Russian officials and merchants were interested in the characteristics and capabilities of Russian floating nuclear power stations. Several foreign countries showed their interest in such vessels: Algeria, Argentina, Indonesia, Malaysia, etc.

For obvious reasons, it is too early to talk about the supply of floating nuclear power plants to foreign countries. The lead ship of this class will be built only in the 2016 year, after which it will take some time to complete a series of floating power plants for domestic Russian needs. Therefore, the beginning of the construction of export analogues of the vessel “Akademik Lomonosov” should be expected no earlier than the end of this decade. At about the same time, it is possible to complete the construction of the next ship of the series for Rosatom.

The FNPP crew of 69 people will control the operation of two nuclear reactors capable of generating up to 70 MW of electricity and 300 MW of heat. If necessary, the power plant can operate as a desalination plant for sea water.

Many cities and towns of the Northern Sea Route would be happy for her. She is mobile, it’s not a TPP to build
Here are just fresh water there is usually enough, but maybe some of the southern buyers desalination interested

How a thing is quite interesting. Only the declared parameters are not completely clear, like with 300mW of heat, and to desalinate 240t.cube of water per hour is just a fairy tale, per day it is real, and even more so per hour. In general, the emphasis is somehow placed on heat and desalination, while the extraction of electric energy is only 70 MW. Connection to thermal communications is initially problematic since It requires a huge amount of softened water, pipelines, etc., desalination is generally an extra device - it’s already where, and in the north there is enough fresh water. The production of such a quantity of heat and steam implies the use of nuclear power plants of the secondary cooling circuit for heating the housing stock, etc. 300 MW of heat is a huge amount. What will happen in the summer when the heat season ends? Where does the hot water go? Into the river? Then goodbye fish. In the event of an accident on the heating main? An emergency power drop? It is also not said whether it can use the turbine for cooling the second (or third) circuit (when it is not used for heating sea water) It has completely different characteristics and aggressiveness. On the barge, a priori, there are neither cooling towers nor cooling radiators - means cooling direct-flow seawater through heat exchangers. In general, in my understanding, the device is problematic from an environmental point of view, in terms of the size of the energy generator. systems and regulation of peak loads. This is neither a nuclear submarine, on a cruise it has no problems with cooling steam generators, and at the pier the boat stands with shut off reactors and connected to ground communications. here they want to do the opposite. I would not want to have a nuclear power plant near by, and even floating.
There were gas in the north, Gas turbine stations are much cheaper, power up to 350mW, maintenance - 20-25 people, while much safer and able to work both on gas and diesel fuel (low sulfur content) .. That's it, thoughts in hearing.

Are you afraid of atomic energy? But what about nuclear weapons of Israel? Sasha, you just envy that such a thing does not stand in the Dead Sea, for example.

So I'm talking about networks, only in networks the water is not spring but softened.

Power, yes, only in this case it will be necessary to reduce the production of electric energy, and who said that in summer there is less electric power. energy is needed, but what about peak loads?

Quote: Uncle

Desalinate will be sea water.

Why? In the north, there is nowhere to go, or will we lower the salinity of the oceans, but what about the wasted energy? Who will pay this loss?

Quote: Uncle

Like on nuclear powered ships. What causes embarrassment?

The embarrassment is that the atomic walker goes across the ocean, and the nuclear power plant will stand on the river (since all the cities of the north (over 200 tons of inhabitants) are located on large rivers or rivers in general (not off the ocean), therefore, how will the discharge of a huge Warm water directly into the river? Think yourself.

Quote: Uncle

Are you afraid of atomic energy? But what about nuclear weapons of Israel? Sasha, you just envy that such a thing does not stand in the Dead Sea, for example.

Come on, you don’t need to desalinate the Dead Sea, and our desalination plants operate on the basis of osmosis steam, like the main thermal gas turbines (I am very familiar with them) Therefore, I say 70 MW nuclear power plants is an empty waste of money. The infrastructure, the danger of radiation, the maintenance staff are more than 3, and the 70 MW output is 5 times smaller than a standard gas turbine unit. In addition, the gas turbine unit has the ability to air-cool, gain power for 20 minutes (250 mW) and 100 MW supplements after 4 hours.
There is no sense in it. I just don’t see as an energetic. Cost kW / hour why not write? Ethio would clarify everything.

And who said that it is necessary to reduce power? Heat at any heat and power plant is a by-product of electricity production obtained by condensing the steam that has been exhausted from the turbines, and in this case the problem can be solved either by installing 2 condensers (1 for heating the city 1 for dumping excess heat) or installing an interesting condenser structures where the second circuit and the outboard third and heat carrier from the city’s heating networks will circulate. Actually do not need heat? He closed the city circuit, opened a more outboard third. That is the whole problem.

Quote: atalef

How will the discharge of a huge amount of warm water directly into the river affect?

In no way will it affect, on the scale of ocean currents and large Siberian rivers (do you agree that no one will drive such a device into a "stream"?) This warm water is literally a drop in the sea.

Quote: atalef

In the event of an accident on the heating main? Emergency Power Off?

See above, automatic transition to full cooling by the third circuit due to the side.

Quote: atalef

It is also not said whether she can use turbines for cooling the second (or third) circuit (when sea water is not used for heating). She has completely different characteristics and aggressiveness.

The circuit operating on the turbine is usually the second, the outboard circuit is the third. Answer: It can. Again see above.

Quote: atalef

and at the pier the boat stands with drowned reactors and connected to ground communications.

I may have forgotten something already, if they correct me, but in my opinion, for a reactor muffled on a combat nuclear submarine, you can put shoulder straps on the table. To "set fire" a zone, you need an external source of neutron radiation introduced into the zone, I doubt that it is dragged there every time. Power should be kept to a minimum, but not damped. Misantrop, correct or confirm.

Quote: atalef

This is neither a nuclear submarine; on a campaign, it has no problems with cooling steam generators

And there is no problem, take water 100 meters upstream, discard 100 meters downstream.

[atalef]

Quote: doktor_alex

And who said that it is necessary to reduce power? Heat at any heat and power plant is a byproduct of electricity production.

Only here is the problem, the amount of heat directly depends on the amount of electricity produced.

Quote: doktor_alex

and in this case, the problem is solved either by installing 2 condensers (1 for heating the city 1 for dumping excess heat) or installing a condenser of an interesting design where the second circuit and the outboard third and heat carrier from the city’s heating networks will circulate.

and another 60 circuits
Only the boiler steam is cooled to a saturated state and the circuits will go to housing, into space or underground - this does not interest him. There is a unit of heat (directly dependent on the amount of power removed from the turbine by the generator) that must be removed. If in summer it’s not for heating houses, it means that there is no direct discharge of heat into the river (through heat exchangers). Cooling towers are not provided.

It is hard to forget what I did not know. The reactor is elementarily suppressed by entering neutron absorbers (graphite, etc.) into the active zone. By the way, they are also controlled by power.
The chain reaction in the reactor does not require the introduction of an extraneous source of neutrons; uranium in itself is their source. It is enough to pull the absorber rods out of the core and the reactor will start by itself.

You probably do not know how to read, that there is no problem cooling it is understandable, I wrote about the consequences for the rivers - such cooling. Because the bulk of the large northern cities of Siberia and the Far East are located on rivers.

iiiii? Do you even read what I'm writing to you? In my opinion, he clearly wrote that in the summer period when there is no need for heating, the thermal power of the reactor will be the same as in winter, the amount of electricity generated by the PTH will be the same as in winter, excess heat will be discharged overboard through the condenser. You opened my eyes like that or what?

Wow, this is brilliant, in other words they wrote the same thing as me, but you are a talent.

Hmm .... what are the consequences? This is actually a transition to the normal summer mode, when all the excess heat through the condenser is discharged overboard!

Quote: atalef

Yeah, what the fuck are you saying? And the teachers fooled me for 2 years .... Everyone told me that there is condensate in the condenser, which is then pumped back through the water heater into the boiler water drum (if you started about steam boilers). And on the nuclear power plant steam generators, I also remember that it was a complete deception, like hanging a steam generator poster, and then it’s a disgrace, because water is at the entrance of the second circuit. With your knowledge, let us teach us .... It is a pity that I had all the professors that were foolish .... sorry ....

And just do, even if you are right, even if the second circuit is cooled only to the state of saturated steam, what's the problem? heat exchange has long been seen "passed"? Tell me the reason why I cannot keep the coolant t of heating networks in the region of 310-320K?

I have a diploma of a marine engineer, specialty Marine power plants, the main direction of the nuclear power plant. Further. Those. Now you want to tell me that, having loaded a fresh company, I will just take it, remove the control rods from the core and voila, the reactor started up? Ahahah, yes, you can even pull out the compensation grating, you don't have a self-sustaining chain reaction without an external source of neutron radiation. Sorry, but you are clearly not competent in this area. Reading Mr. "Misantrop" it is clear that he touched the nuclear power plant with his hands, but reading you it is clear that you do not have any deeper than Wikipedia in this area of ​​knowledge.

I revered you and realized that you also don’t know much and don’t know how. And probably you can hardly imagine the amount of warm water diverted and the scale of a large Siberian river. Apparently your imagination draws waterfalls like boiling waterfalls at hydroelectric power stations.

[zardoz]

I’m wondering. Can you imagine what summer is in the North? For example, in Salekhard it may not be at all. In terms of temperatures above zero, it may not rise for the whole year, a rarity, but it can. Then there is such a thing as fuel storage from summer to winter. This fuel with such a station can be saved and used only in emergency cases and possibly in warm periods of time when it is not practical to generate so much energy. Or by reducing the capacity of the reactor to produce the missing electricity in other ways. This is to reduce thermal pollution, if such a problem exists. Regarding your statement about softened water, it’s not even clear. What is the problem? Do you know the water hardness in the vehicle in the north? and even if it is very hard, what is the problem with the heat exchanger?

Not always. In March 93, after an accident at a razdatka of the Kola NPP, they brought one side of an old 667A and threw food to the shore. Despite the fact that the nuclear submarines have not too powerful coastal connectors (6 pieces of 1000A each at a voltage of 380 V), the village, headquarters + all the flotilla ships located in the base with the retrieved installations, SRB, RTB, TTB, PRZ, etc., were quite enough. Those. to all consumers of this branch. And with a decent margin.
Well, with regards to power adjustment, this is done with a light movement of two fingers of the watch operator and takes really seconds. Synchronizing power with shore power is generally ridiculous. This operation was done in passing by any duty officer on the power plant before turning on the dampening pumps.

IMHO it is not necessary to seek out global problems where they have not been found, ALL of the above problems are successfully solved and verified by the experience of operating hundreds of ship nuclear power plants decades ago

At cham, there are accidents and regular work. We also have a mobile turbine (from Hercules) that mates with the generator through an air clutch. (40 mW by the way, for emergencies) only electricity is almost gold (because it works on diesel fuel) and the efficiency (due to heat loss and air connection) is very low.

It seems like at ordinary nuclear power plants, energy was never cheap ... Rather, the most expensive (well, before the appearance of all kinds of windmills and solar panels). Well ... in the reactor, the acceleration / deceleration cycle is quite long. How will they control the frequency-power?

Just always, she was one of the cheapest.

Our speed is always the same, at least at the minimum load, at least at the maximum, since the frequency is tied to the speed.

Of course, the same speed as frequency directly depends on this. Maintaining the required speed is achieved by supplying the right amount of steam to the turbine, therefore, due to the high reactivity of the TPP boilers, they are kept at as constant a load as possible.

In essence, this is a new class of ship. In the north, and not only, the thing is useful.

But in addition, it’s quite dangerous. It’s essentially a float. You can’t put it in earthquake-prone areas. Kamchatka is no longer there. It’s also a dubious undertaking. Moreover, a special vessel is needed to collect spent nuclear fuel.

Not certainly in that way. The turbogenerators available as part of the shipboard nuclear power plant can take on no more than 15% of the reactor power. Everything else is used by main turbines, refrigerators, evaporators, etc. It turns out that efficiency is too small if used normally as a nuclear power plant. And to hang a generator on the main turbine of the appropriate power ... is also not easy. He himself is not small in size, requires cooling, lubrication, etc. And power cables are needed more powerful. Not so simple ...

[cdrt]

And additionally.
I repeat - in a single electrical network, the supplied power should be equal to the consumed. Otherwise, all sorts of troubles there begin with a frequency, well, and as a result, with the operability of all the electric motors connected there. And so that this does not happen, automation disconnects the necessary network segments - in fact, this is called a fan shutdown.
Therefore, in the UES of the Russian Federation there are stations that provide a stable "basic" power - hydroelectric power plants, nuclear power plants, most of thermal power plants. They are economical, but the power changes for a very long time - hours, days, or even weeks :-)
But there are stations that must respond to commands from the network manager - i.e. respond in minutes, ten, fifteen minutes.
It is clear that on them and the units are small, i.e. less economical, but they accelerate / slow down quickly, which is necessary in order to adjust the frequency-power.
AEU anyway - slow. It is unclear how they will regulate the 200 thousand grid. Apparently the presence in the same network of small "fast" thermal power plants. At the same time, there will be a curious situation when the energy on the regulator will be cheaper than on the base
Something like this ...

Well, do not confuse STATIONARY NPP with TRANSPORT. There TOTALLY different reaction rates, principles and possibilities of regulation, the mass of the installation, the materials used, etc. The reaction rate to a change in power in tenths of a second (if within small limits) and several minutes, if you are satisfied with a large number of powerful consumers? By the way, transport units are designed with a negative temperature coefficient, i.e. have the property of self-regulation of power in the entire temperature range. That in stationary installations does not work due to the characteristics of the fuel used. Since stationary plants, in addition to generating electricity, also burn plutonium-239 during the campaign. 2 kg of 239 plutonium per 1 kg of burnt 235 uranium

The news is good, but I have to upset you that with such a policy in relation to energy tariffs in the Russian Federation, there will be no "cheap energy" ((As examples: - 1 kW / hour - Vladivostok (for individuals), about 2.08 rubles. (I can be wrong, for a long time he himself did not fill out receipts, his wife does this))), sale to China - 1 kW / hour - 0.91 rubles! How can I understand...?
Also, the recent scandal, when in Kamchatka, at a geothermal power plant, the price was raised by 15 or 18% for consumers ... Consumers asked the company's management, on what basis?

yes good to complain, in the Moscow region tariff 4.01 , but lately there has been an active gasification of the eastern part, so soon heating can be converted to gas - more economical, and everyone is switching to energy-saving technologies - there are simply no options and no one wants to pay a lot. Do you have such ridiculous prices because of the Bilibino NPP? a lot of extra energy? it’s just that you voiced one-sidedly, your complaints about prices are not entirely clear.

Do you have any idea?
for comparison, you quoted the final prices as a consumer (2.08 p.) and in China they sell wholesale for a mega-regulator, which then sells to individual energy companies, and they, in turn, wind up their profits and sell to end users ...

reference:
"Let's compare prices !!! The cost of light in Russia is slightly different from the Chinese.
We used the currency converter on our website and got the following layout:

in China
at home - from 3.04 to 3.80 rubles (in the south) and in the region of 2.54 rubles (0.5 rmb in the north, in Beijing)
in production (in the South) - 7.61 rubles (1,5 rmb);

in Russia:
at home - 2.50 rubles (0.49 rmb);
in production - 6 rubles (1.18 rmb);

In northern China, electricity prices are slightly lower. Why is it so? Most likely, this was done in order to reduce the flow of people who want to move from north to south. "

[GHG]

The reason is that there are areas with a deficit and surplus of electricity.

[NOMADE]

As it were, everything is correct, but by what methods this is achieved, see below.

[GHG]

Do you know what constitutes an electricity tariff? The initial cost is the selling price per kW, goes to the owner of the power plant of TGK, OGK, etc., then it (electricity) is distributed by regions, oblasts, districts, cities. This is done by IDGC, FGC. Further, there is a mark-up for all kinds of grid companies. But it is necessary to maintain the lines, substations in proper condition, because so much was lost in 90-2000. Physically and morally the equipment is outdated and worn out. We overpay for updating the equipment, the Chinese have a shorter "food chain" and have signed a long-term contract. This system is complex, but I understood this issue as it should be.

[Sol_jah]

Quote: Sol_Jah

Now everything is in the hands of the capitalists. More sold, more profits

it is not possible to produce more electricity than consumption per second, or the frequency characteristics change, threatening the collapse of the entire energy system and the failure of equipment (mainly engines and drives)

[GHG]

By the way, there was enough electricity in the USSR. With a decrease in generation, the frequency drops. Which is unacceptable for equipment. You probably had the fact that you can operate power plants in different modes. In the summer, no one will run the CHP at full capacity, since excess heat will have to be thrown into the atmosphere through the grating. Is it more profitable to run it at full capacity in winter, and let the condensate into heat exchangers? Here you just need to know the expected load, for a month, day, hour and enter the estimated required power by the required time. And the automatics dealing with "primary regulation" of frequency and voltage will cope with small power drops.
A power plant can give more power ... but there is definitely no frequency more than 50 Hz ... the automation will not give it, it will give it a load of exactly 50, if it will be much less ... for example 49,5, then system automation will disconnect some of the non-responsible consumers of the third categories. The system will definitely not fall apart just like that, the part with its generation and consumers will separate. It just seems like the case of which ... the Sayano-Shushenskaya hydroelectric power station failed and why? Some consumers simply turned off, other stations gained load in seconds ... in short everything redistributed and EVERYTHING.

Subsequently, problems followed in initially unaffected areas, including all 5 districts of New York City and parts of Long Island, Westchester County, New Jersey, Vermont and Connecticut, and most of southern Ontario, including Toronto.

You probably had to operate power plants in various modes

In general, you understand that there were at least 5 stations in terms of operating modes - TPPs and Thermal and NPPs - that are required to operate at 90-100% of capacity since thermal coefficients during power drop and, as a result, expansion or contraction of equipment due to temperature differences leads to rapid wear of both turbine blades and the entire steam-powered equipment, so they tried not to touch the peak ones (mainly Hydroelectric Power Station, Hydroelectric Power Station and Gaes) 60% of turbines are running smoothly with the start-up and almost instantaneous output of capacities at peak loads. The latter (PSP) simply worked as pumps during the failure of consumption and pumped water from the lower pool to the upper one (this loaded fuel cells and giving a load), and transformed into minute maximum turbine and taking water from the upper pool to the lower peak loads quenched.

Quote: GES

. In short, everything was just redistributed and EVERYTHING.

Of course, with a decrease in generation and as a result of a drop in frequency (while maintaining constant consumption), there is no other way but to discard consumers in importance, only you do not take into account the electrical system and (the ring as a whole) as the reactivity of the system, the reverse connection of consumers (with a peak inclusion) and of course phasing. I hope you never had to participate in the return to work of the electrical system (In my case with 400 kW lines), which was divided into 3 enclaves, with excess generation in the South, lack in the North and a separate ring in the center, When a part of the power plants had to be extinguished , part disconnected in frequency (and dropped consumers) ---- and then synchronize the rings (and this is half the country) and all because of the fire, when insulators on 4 lines (161 kV) burst from the heat, and the remaining 6 (communication with the center and the south) disconnected from the sharp overload. Only 18 hours took to recover.

Now (for more than 20 years) I have been working in the Israeli Electric Company (such as RAO EU). Department of substations and load distribution (this can be translated)

Indeed, in Russia there is neither at the stations nor in the networks of power engineers. The head of the power industry is called in some other way (in the regulatory documentation) as the person responsible for the electric power industry.

And it's easy to understand. They sell to the Chinese how much they take, they will offer more - they will refuse.
Well, the residents of the Russian Federation have nowhere to go. They will pay ANY price.
Actually, the growth of tariffs of all state monopolies is limited only by how many percent per year the increase in prices the population of the Russian Federation can tolerate ...
Nothing more.
Moreover, in recent years, the state has vigorously created monopolies wherever it could reach. What is the action, such is the result. And gas will be more expensive, and railway tickets, and energy.
I remembered a good example. I flew remember in Naberezhnye Chelny. since 2005 weekly. Only Ak Tatarstan flew. In my experience as a passenger, this is the worst airline I know in the world (I’ve traveled not a tourist, I’ve traveled to 39 countries today). So - in May 2008, Msk-N. Chelny tickets cost 19200 rubles round-trip. for 1h50m flight on the half-dead Yak-42, feeding - tea and waffle.
In May 2008 he flew to New York. Ak Delta (also not the best in the world by the way ) Moscow-New York round-trip 18300 rub. For 8 hours on a very so-so comfortable plane, 2 times per flight normal feeding.
The most miracles began further. I bought the airport in the low-frequency KAMAZ. Well, I immediately agreed on flights with 2 more airlines. Those tickets were made for 2000-3000r. There and back again
This is a good visual explanation of the influence of monopoly on prices.

[biznaw]

The total costs are all together, and what you mean by calling them full are called conditionally constant, since they do not directly depend on the volume of production. The salary of effective managers, in contrast to welders, locksmiths, and other workers "on a deal", is precisely taken into account in the conditionally fixed costs. The death of most of the "collective farms" is directly related to the availability of effective managers' salaries in the UPZ, or as they used to be called "red directors".

this energy does not shine for our northern cities and ordinary people. all this in the framework of offshore oil and gas production, which will go abroad where all the revenues from the sold raw materials will remain.

[AK-47]

Not so simple.
A floating nuclear power plant is the brainchild of a shipyard, which means that it is much more technologically advanced than the modern process of erecting nuclear units, in which concrete construction is continuously interspersed with installation operations. Such a pontoon can be towed by water to almost any area, and then it becomes at the mooring wall. However, the requirements of the Maritime Register poured here, as if from a cornucopia: provide an ice-resistant pontoon hull, provide ballast tanks, roll and trim systems, anchor winches, spiers and windlass, food warehouses and galleys, cabins and cockpits, rescue and navigation equipment and a lot of elements of the ship's nomenclature, which many times increase the weight load and the cost of the project. A floating pontoon is not a safe solution for storing active zones unloaded from the station reactors. In addition, every 10 years the pontoon must undergo factory dock repairs. This means that for this period the consumer will either have a shortage of energy, or an equivalent replacement of the lost power should be ensured, which will lead even more to the cost of the project. Obviously, in order to exclude navigational accidents, ice piles and hummocks, a pontoon will require the construction of protective structures in the water area, which also seems to be an expensive facility. The personnel serving the pontoon station operate in a shift mode by analogy with a ship, which again makes operation more expensive, like any shift method.

[Wedmak]

And how much will the construction and operation of a surface nuclear power plant in such inaccessible areas cost? I think this is still a lot of money and a big headache. Both during construction and during operation.

[afire]

in any case, it’s help to the north, but it’s expensive, our north has never been cheap, but it’s a lot of energy and its extraction does not constitute a headache in such a project, and maintenance - and whatever it is - everything needs to be maintained and everything needs to be monitored otherwise they won’t move anywhere. And the north needs to be developed, the NSR can be supported by local residents only + from this, since due to the available energy it will be possible to build new energy-intensive industries. Therefore, I believe that it is better to invest a lot in such projects than to steal.

Elementary. A nuclear power plant with a capacity of 90 mW has 2 main capacitors (ATG and GTZA connected by a jumper in pairs) with a working diameter of just over 1 m and a length of about 2 m. It is quite enough in all modes. There really isn’t that much heat that needs to be dumped. Steam in the turbine is triggered almost to the water, the 11th stage is already almost kneading water

Well, do not get into steam turbines if you have been dealing with gas turbines all your life, and you have heard about steam only from theoreticians at the institute. A quarter of a century ago ... I don't go to gas. Simply because I do not have sufficient information for this, except for general provisions. And by profession I am an operator of ship nuclear power plants. With considerable experience in practical operation and repair, including in a combat campaign. So this "saturated steam" was repeatedly seen alive. After the ATG with its active turbine - yes, saturated steam, but the main active-reactive turbine, the steam heat drop is almost completely triggered. For reasons of efficiency, a turbine of this type will obviously be installed on the projected installation, so that if steam gets there, then only through the etching valve discharge system (provided that there is one at all, they do not need particularly fast maneuvers)

And in order to reduce the consumption of electricity by the population, they lobbied through the Duma - "the social norm of electricity consumption." Want to laugh at this norm? This is 120 kW for 1 person.! It was supposed to take 2-3 times more money over the norm! If it had not started "seething" among the masses, they would have introduced. But the governor was afraid of a social explosion (+ elections soon), and the introduction of this project was postponed.

To be honest, you are interested in this. Then take an interest in this topic BALANCING MARKET and what kind of organization "SO UES" is. I myself have previously worked in this system and I know how rates for overruns are increased. This is a SYSTEM OPERATOR OF A UNIFIED ENERGY SYSTEM. They are guided by only one rule, pay too much, and if you are a large businessman with your large enterprise and did not get enough money before your application, then pay too.
All this under the pretext of improving the quality of electricity, i.e. constancy of frequency and voltage.

But by the way, why is it unfair ... If you have badly planned your production, this is your problem, why others should suffer because of you (more precisely because of your downtime) - the same power plants will have to produce less, the proceeds will be counted. And all because you are ... unreasonable. If you don’t want to, conclude a good contract with an energy sales company, buy it yourself, turn around ...

What you planned is what you buy according to the norms. the price of everything above market value ... it’s more expensive.

and for this business it was possible to adapt "sharks" with their capacity of 380 MW for both reactors, and any decommissioned submarine after repair and refinement. so also safety in the event of storms or devastating tsunamis, undocked in depth

For me, such a floating nuclear power plant is extremely necessary for us. And how much, the operation will show.

[Foooxxxxx]

It is necessary to refuse nuclear power plants, and they still make floating ones, God forbid some kind of catastrophe in the ocean, this was still not enough ...

[Vitaly Anisimov]

We were one of the first in the world to build peaceful nuclear power plants .. They work in many countries of the world .. (Chernobyl is a muddy story ..) Floating nuclear power plants is not a bad idea for the North of the tundra .. They need to be there (deer to light up !! joke !!) ..SIBERIA AND NORTH is a stronghold of Russia !! There would be more such floating stations !!! We would have muddied such things there !!!

[alex86]

I have vague memories that in the 60s, along with the implemented mobile nuclear power plant, there was a floating one (or had a dream? ...) But discussions and development were definitely ...

A good "thing" for feeding a combat laser.

Apollo, ! Yes, the casket itself simply opens. The decision to build the FNPP on Sevmash was made when the plant had an order for only two nuclear submarines and the prospects for new orders were still vague. And vice versa - “Academician Lomonosov” was removed from construction in 2008, when the plant had four nuclear submarines at different stages of construction, two more were awaited, the Northern Fleet was repaired, and Admiral Gorshkov was upgraded for the Indian customer. At the same time, the Baltic Plant was on the verge of survival and did not have large orders.
As a result, it was the order for the FNPP that allowed the Baltic Shipyard to retain competence in the field of nuclear shipbuilding (it should be noted that in addition to the platform itself, the Baltic Shipyard produces steam generators for KLT-40С reactors). For the construction of the FNPP in June of the 2012, the plant received a Rostekhnadzor license for a period up to 2017 of the year, which permits the assembly, installation, commissioning, testing and testing of equipment and systems of a nuclear installation, installation and commissioning of nuclear reactors, as well as their preparation for loading nuclear materials at the FNPP and the future nuclear icebreaker, the contract for which at that time was not yet. So this project, unless of course there is a potential buyer, will remain in a single copy.

Bring such a thing to the South Pole and you can build a small city on an ongoing basis. To stake out the main place, then let the world public fall as much as you like, anyway they will come and beg for electricity.

It is impossible. Nuclear-free zone. Nuclear-powered icebreakers are prohibited there.

Here it is - a tool for developing the North and the Far East! We drove it to the right place, if necessary we dragged it ashore, or artificial ground. We drove a floating (or modular) oil refinery or gas liquefaction plant. And export the finished product. More than sure- - if there will be floating nuclear power plants - there will be floating processing plants. And specific parameters will still be specified in accordance with specific tasks. It is simply striking that there is an attempt to create a universal mobile installation for all occasions.

I wonder how this thing has security?
And by what forces will its security be ensured?
