An incident at the Rivne nuclear power plant in Ukraine is reported

Reports of an incident at the Rivne (Rivne) NPP are coming from the territory of Ukraine. According to the latest data, a hydrogen pipeline was depressurized at one of the four nuclear power plants in Ukraine. The emergency situation with the pipeline manifested itself in the area adjacent to power unit No. 3.

The reports of the State Service for Emergency Situations of Ukraine contain information that this power unit is currently undergoing so-called preventive maintenance.

From the report:

The pipeline with a diameter of 50 mm was depressurized and hydrogen burst out without its further combustion.

It is reported that, according to the regulations, the hydrogen supply was urgently shut off.

If you believe the reports of the State Emergency Situations Service of Ukraine, then as a result of the incident there are no victims or injured.

From the service post:

Measurements of the radiation background at the Rivne NPP show that it is within the normal range. The power units currently in operation are operating normally.

For reference: Rivne NPP was commissioned in the Ukrainian SSR in 1980. At the moment, the station consists of 4 power units. These are 2 units based on VVER-440 reactors and two more on the basis of VVER-1000.

Since 2019, this is at least the 5th emergency at the Rivne NPP. Moreover, all these emergencies are associated with the 3rd power unit. For example, in April 2019, the unloading of power unit No. 3 took place due to the shutdown of the main circulation pump.

Something the European Union is not eager to prohibit the atom to Ukraine, but it would be worth it.

[Nexcom]

someday they will fly up (God forbid!) with their self-made repairs ...

[Fedor M]

In this case, in Europe, all the heads of state will fly up "from their chairs"

[knn54]

It was lucky that there was no FURTHER BURNING after a flash of hydrogen.
In September, the SBU conducted anti-terrorist exercises at this nuclear power plant, according to the legend of which a sabotage was being prepared at the Rivne nuclear power plant.

Hydrogen at nuclear power plants and thermal power plants is used in the cooling system of generators. Similar incidents occur in many countries. In Czechoslovakia there was an accident with an explosion, there was serious destruction, we were shown photos from that accident.

[Villain Tim]

This is already a bell. Train and not the fact that to prevent

[volodimer]

Westinghouse is also going to supply kosher TVELs there. We are waiting for the results. With horror.

[GUARD]

Well, yes, an emergency at a nuclear power plant is always on the verge. Colleagues who are versed in the industrial use of the atom, explain what is the threat of this incident?

[Stepan S]

There is no radiation hazard. Accident in the pipeline that supplies hydrogen to cool the generator.
Application of hydrogen cooling system:
- reduces ventilation losses and friction losses of the rotor against the cooling medium;
- increases the power of the turbine generator at the same electromagnetic loads;
- increases the reliability and durability of the winding insulation;
- eliminates the danger of ignition of the winding, since hydrogen in the TG housing does not support combustion and breakdown of insulation does not entail a fire;
- the noise inside the working generator decreases, since the hydrogen density is insignificant;
- reduces the surface of gas coolers compared to the surfaces of air coolers.

The hydrogen cooling scheme of the TVV-1000-243 turbine generator provides filling of the generator with hydrogen, maintaining the nominal pressure and replenishing the hydrogen leaks that are inevitable during operation. Nitrogen is used to safely fill with hydrogen and remove it from the generator. Hydrogen or air is introduced into the generator body through the collector located in the upper part of it, nitrogen is introduced into the generator body through the bottom.

There is no radiation hazard, right. But such handling of hydrogen is fraught with ... the generator will be destroyed - it will take a long time to restore and it is painful for the money ...

[Stepan S]

Yes, there is no circulation, but the state of the pipeline is so sad. Hydrogen causes embrittlement of the metal. It is necessary to monitor, change the pipes on time.

[210ox]

There is a whole complex of equipment, electrolyzers, automation and control systems .. And you need to keep an eye on everything.

This is to the question of whether the old GTS will be able to transport hydrogen to Europe ... this is by the way ...
And so the question is that this winter they were going to hold out at the nuclear power plant

At the same time, according to Galushchenko, the Ukrainian government, in the face of a rapid rise in hydrocarbon prices, is betting on nuclear generation. “We have optimized the overhaul campaign of nuclear power plants, and this year, in fact, our nuclear generation will operate at a record capacity: we plan to operate simultaneously 14 units [NPP] out of 15. In comparison with the previous heating season, the expected production volumes of nuclear power plants will increase by 5,5 , 3 billion kilowatt-hours, which reduces the need for coal by approximately 12611043 million tons, "- says Galushchenko. https://tass.ru/ekonomika/XNUMX

And there is not enough coal there at times - the country's energy system operator Ukrenergo - "The situation with the accumulation of coal is getting worse. The reserves in the TPP warehouses are extremely low. In accordance with the fuel accumulation schedule approved by the Ministry of Energy, there is 4,7 times less coal in the warehouses. than it should be on October 25 "
To buy electricity from Russia and Belarus somehow ... and any such accident at peak consumption, when there is nothing to support - this is an overload of the system, and then there is a blackout (the word is when there is a socket, but there is no light) ...

[dedusik]

So long ago, experts said that it was impossible to transport hydrogen through the existing GTS.

[Fedor M]

They still have no money, so it won't hurt))

[gridasov]

If you in your right mind analyze what you said, then obviously the process itself is so ineffective that it is necessary to use secondary technologies to compensate for negative factors. Therefore, I am talking in the void about dynamic reactors, where all the voiced factors are impossible as a process.

[lucul]

eliminates the danger of ignition of the winding, since hydrogen in the TG housing does not support combustion and breakdown of insulation does not entail a fire;

Yeah, but any depressurization of this circuit is enough and such a fire awaits you that it will not seem a little))))

[Proton]

This is also provided for in the generator design - there (in the cooling system) an overpressure of hydrogen is created with constant control.

[Vladimir_2U]

Quote: Stepan S

There is no radiation hazard.

They just calmed me down. True, people are interested in how things are with fire safety?

[Proton]

If you use the data from the article, then there is nothing wrong with such an incident.
Hydrogen is used as a coolant for the generator. Lack of (short-term) proper cooling will not lead to problems. Stopping the generator in an emergency is not a problem.
The reactor itself has nothing to do with it.
If we also take into account that it was during the repair work, then the maximum that will happen is the local combustion of hydrogen.

[sifgame]

Everything is cool. There is no danger, nothing to do with the reactor, the radiation background is normal. Leakage of hydrogen is completely safe, and a local ignition is even more safe at a nuclear power plant. Everything is completely safe.

[bk316]

Colleagues who are versed in the industrial use of the atom, explain what is the threat of this incident?

In short, nothing.
Here another strains.
A large number of minor accidents.
Most likely, this indicates either the deterioration of the equipment (in a broad sense) or non-observance of the instructions by the personnel. Yes, all equipment is accessory YET. Sooner or later, this will affect the reactor or any critical system. It's like in an old car that does not undergo regular maintenance. First, the headlights burn out, the tips are loose, the shock absorbers are leaking, but the car is moving. Then grunts and the brake pipe burst or the clutch pedal failed.

[Avior]

It also says that the unit is undergoing preventive maintenance, that is your MOT.

[bk316]

It also says that the unit is undergoing preventive repair, then your MOT

Unfortunately no. Then you have to go to the officials Officials are the Russian Federation, 404 refused our services. So this is not THAT but hell knows what. I can describe in more detail, but this is not entirely on the topic.

[Avior]

THEN you need to go through with the officials laughing

Officials are RF

I can describe in more detail

need not
Just give a link where and in what official documents this requirement is written.
For the maintenance of Satan missiles, for example, they did without it ...

[bk316]

If you have international agreements, then they do not exist. After all, 404 did not build the nuclear power plant itself and did not order from others. The nuclear power plant was built by the USSR. And if we are talking about the laws of the Russian Federation as the heir to the USSR, then please.
Operation, maintenance, any construction and modification of nuclear power plants (not only reactors, but also the entire nuclear power plant) is a licensed activity.
Read here https://atomaudit.ru/
I did not receive any licenses for my 404 organizations.
Of course, you can license yourself, or you can also license yourself in Gabon or with the reptilians. But except for the Sumerians, no one dared to do so.

Moreover, each nuclear power plant (and all Soviet and Russian ones too) is certified by the IAEA. There are signatures of the IAEA commission, designers, builders and operators. So, not a single certificate of Ukrainian nuclear power plants is signed by any Ukrainian organization. So, legally, they not only cannot repair it, but also operate it.
So if according to the letter of the law, build your own nuclear power plant or re-certify this dear Ukrainians.

Actually, I can give you a link to the corresponding source, but you will not go through it.

[Avior]

on the laws of the Russian Federation as the heir to the USSR

RF is the legal successor of the USSR under international treaties and agreements.
This has nothing to do with the rules for the operation of nuclear power plants.
The GAN / FSETAN license applies to work within the Russian Federation, the link clearly states "Valid throughout the entire territory of the Russian Federation."

So if according to the letter of the law, build your own nuclear power plant or re-certify this dear Ukrainians.

If, according to the letter of the law, this is pure fiction

Like, for 30 years of operation, they have not learned how to carry out maintenance? And meanwhile, recently, a reactor was shut down at a Russian nuclear power plant.

[bk316]

Type in 30 years of operation have not learned to carry out maintenance?

And how to learn if everything remains in the Russian Federation?
If the entire industry, including the leading institutes, including universities, including EXPERIMENTAL NPPs, (yes, we have such), including the entire system of nuclear supervision, remained abroad?
It is time.
In addition, all these years, nuclear power 404 degraded. It was in the Russian Federation that new stations were built, reactors of a new design were developed and put into operation, scientific developments were carried out on new types of reactors. And in 404, they simply finished off the resource of existing nuclear power plants.
This two.
And finally, due to the general chaos and poor state control in 404 at nuclear power facilities in Ukraine, it has become normal to make unreasonable (technologically unreasonable) technical decisions. Well, like assemblies from Westinghouse.
These are three.

Meanwhile, recently, a reactor shutdown took place at a Russian nuclear power plant.

This is just fine. If you were in the know, you would know that this happens all the time around the world. This is not even an incident according to the IAEA classification. However, like the situation described in the article.

I'm not talking about the fact that now everything will crash. It's about a trend. Ukrainian nuclear power plants are aging, many of them are beyond their service life. Proffies (cadres are aging) there are fewer and fewer and politicians begin to make decisions. Nobody wants to make investments in capital. And political will is not enough and will not be enough to close the nuclear power plant. After some time, accidents will begin, which will be more and more serious.

[Avior]

Nothing for the reactor. Hydrogen has nothing to do with it.

[The leader of the Redskins]

For a reactor - nothing.
And for the couch generals - a decrease in the level of negative news in Ukraine. Here one commentator has already noted the "flash" of references to the neighboring country.

[GUARD]

Mercy, colleagues, reassured. And then in Ukraine everything is on the palm of your hand. Nearby after all.

[boris epstein]

Chernobyl extinguished the WHOLE UNION! Who will extinguish Rivne now? The specialists have mostly dispersed, hence the constant minor accidents, which at any moment can turn into one big one.

[Seryoga64]

They lie. It would be a trifle ... no one learned anything

[210ox]

In the energy sector, all this is recorded and notified.

[The popuas]

Here on VO there is a tendency, however, every 'bunch' from Ukraine to cover

[210ox]

Politics however. The girl is dirty. Fingers and IN. In general, an ordinary incident is described as a harbinger of disaster. This happens often and thickly all over the world.

The disaster is already Ukraine itself.
The main thing is that the "precursors" generated by the "catastrophe" do not touch all the neighbors and then do not flicker for decades.
I remember a couple of years ago in Ukraine, the Americans were allowed to the waterworks with dams, which is also very annoying. If the stations with the American TV elements are destroyed and the dams collapse, then a century will not be enough to clean up the consequences.

[prior]

Ukraine has experience in blowing up power units.
These can ......

[Nexcom]

... and then the Russian Federation will be accused as always.

[valentine light]

As if the incident is not life-affirming.
The nuclear industry in Ukraine should be limited by the IAEA or should be watched more closely.

[Roma 1977]

Yes, everything is fine. Exactly - it is far from Russia, and close from Poland.

[Luminman]

Monkey with a grenade! It is necessary to take away all complex equipment from the cakers, otherwise, God forbid, they will blow up half the world

I have always said, I speak and I am ready to repeat again. For chubatykh - pig breeding - the limit. And not higher.

With such news, it would be time to isolate the whole of Ukraine under the dome, away from sin ...)

[avib]

I myself am from Rivne and studied there at the Faculty of Civil Engineering. One lecturer told us that if they were looking for the most unsuccessful place for the construction of a nuclear power plant in the Rivne region - something worse than where the station was built - they simply would not find it.

[Rock616]

As I understand it, you are already preparing, if it bahn, then blame the "bloody scoop" for this? Well, like you built it in the wrong place. Where is it necessary?

[engineer74]

But it’s interesting, when they have a reactor, will the radiation be democratic and beneficial, like in Fukushima, or terrible totalitarian, like in Chernobyl?

[verdict]

It seems that the employees of the Rivne NPP will bypass us)))

[Andrei Nikolaevich]

The speaker was successfully built. Closer to their "Eurobrothers". God forbid, something happens, Europe - chubaty - one place will turn inside out. There are fairy tales about the "brotherly" people, they do not roll ...

depressurization of the hydrogen pipeline

Some cunning hikhil made a clipping to pump hydrogen to Europe.

Now the pan-headed people will begin to squeeze everything from the Soviet nuclear power plants to the maximum, and it is not clear how it will end !!! God gave the neighbors !!! Where is the GDP looking ?!
