Due to an emergency, disconnected from the network of the 3 unit of the Rivne NPP

Another emergency situation manifested itself at one of the Ukrainian nuclear power plants. This time, problems were identified in the cooling system of the third power unit of the nuclear power plant in the city of Rivne (RAES). Press office of the Ukrainian Energoatom reports that at about half past midnight local time, the 3 unit of the nuclear power plant was shut down:

10 May 2016 of the 00: 32 power unit No. 3 of the Rivne NPP, in accordance with the agreed operational request, is disconnected from the grid to eliminate leakages in the cooling system of the generator stator of the turbogenerator TG-5.

According to some reports, repair work will be carried out over the next seven days.

Two power units (of 4-х) with total capacity with a total load of 1380 MW remain in operation at the RNPP.

At the same time, on the second power unit of the same station, measures of the so-called average scheduled preventive maintenance are held. The reactor is assembled and steam generators are sealed. Repair work at the second power unit has been going on for over a month now.

The press service of Energoatom claims that the background radiation in the area of ​​the Rovno NPP is still in good condition (about 9 micro X-rays / h)

For reference: Rivne NPP is located in Kuznetsovsk. Commissioned in 1980 year. Reactor types: VVER-440 and VVER-1000

It is not said which rods were used. I believe that even if Russian rods were used, the qualifications of the staff are not up to the mark!

[St Petrov]

yes it's time to close all production. leave the beds and seeds to give. So that on the Khreshchatyk!

Well, of course you can trust pigs to breed and make potbelly stoves in shipyards, too!

So to speak, they will be more intact and their neighbors will not be affected!)

Fools may pass by. Title is not correct

"On May 2016, 0.32 at 3 (time corresponds to Moscow) power unit No. 1000 (VVER-5) of Rovno NPP, in accordance with the agreed operational request, was disconnected from the power grid to eliminate leaks in the stator cooling system of the generator of the TG-XNUMX turbine generator."

This station passed the IAEA test, which was highly rated for safety.

This is not the point) I think the more actively Energoatom will buy and use at its stations fuel from the Japanese-American company Westinghouse instead of the Russian one; fuel is not only cheaper, but also quite successfully used at other European nuclear power plants of Soviet projects (in itself a topic for a separate conversation), the more dirt will pour on it

1. Westinghouse does not recycle, and this at cost is not cheaper than getting the fuel itself.
2. What are the examples of successful operation - depressurization of Westinghouse assemblies is very frequent, many times more often than Russian ones. Let me remind you - Westinghouse R&D in material science for fuel elements with uranium oxide was not carried out in the same volume as was done in the USSR, as a result of which the alloys are vulnerable to neutron swelling during prolonged irradiation.

What are you ???
Chernobyl alone was not enough for you ???
For especially stupid !:
You will not pour 98th gasoline into the Belarus tractor ... The valves will burn out!
And in the 600th "Merin" DT, too, you will not start - it will drive worse than "Belarus"!
What about a nuclear reactor? This is not "Belarus" and not "Merin" !!!!
Fuel for a reactor NORMALLY can be made only by those who DESIGNED it !!!!! Because the technologies for the production of nuclear fuel are INDIVIDUAL !!!
Copy - it is necessary to rebuild ALL enrichment technology in exact accordance with the technology of the developer !!! And this is almost IMPOSSIBLE !!!
Otherwise - ALWAYS there is a risk that something will go wrong!
I'm not even talking about the fact that the "Yankes" all machines are graduated in the "inch system", and in ours - in the "metric", and here every micron has a meaning!
That is why the world practice is: WHO builds the reactor - THAT and supplies fuel !!!!!

[Stalker.1977]

Whether there will still be, the most interesting is to come.

[The black]

Nuclear power generation in Ukraine is becoming dangerous. Therefore, and also for internal competitive reasons, the European Union wants to CLOSE NUCLEAR PLANTS in Ukraine. For this they need a reason. The reason will be another accident. To create the prerequisites for an accident, it is necessary to introduce some "innovations" into the well-established and completely reliable technical process. That's what American fuel is needed for. The Ukrainians themselves, together with them, will create an accident - and the EU will demand the closure of "dangerous and depleted" nuclear power plants in Ukraine.
The idiots who stand up for American fuel understand everything perfectly - they just got money from the Europeans for their own pocket for destroying the Ukrainian nuclear generation. Under the cheerful shouts and races of the Maidan. "That is not a jump, that m.s.k.a.l.l."!

At the same time, the Americans themselves at the level of the State Department with the hands of their Ukrainian puppets want to ruin the Ukrainian nuclear power plants, and they will be especially happy if this happens with bright accidents. The purpose of these actions is to get a poor embittered population. That, in turn, is necessary (paradoxical as it sounds) to make it easier to set a zombie mass of Bandera against Russia.

With modern security systems, it will be extremely difficult to implement, even on purpose. Nobody except for fans of conspiracy theory needs such a catastrophe.

What do the rods have to do with it? This is a turbine generator. The generator's cooling system has nothing to do with nuclear fuel at all. Moreover, the generating capacities are shut down, and the reactor of the block itself is most likely "feeding" steam to TG-2, since the "boiler" of the 2nd block has been brought out to the PPR.

The United States imposed the rods on what it placed in power as a result of the coup, to use their fuel rods, which are not only more expensive than Russian, but also not suitable for Soviet nuclear power plants, which was proved as a result of experiments in Eastern Europe and Ukraine, more than once, almost led to disasters. Their fuel in our reactors behaves unstably, overheats and leads to very serious emergency situations.

I agree. In addition to all this, for sure, there is a lack of operating specialists (the same trouble as we have).

Those. They also have technical support, as they believe, should be "independent", with all that it implies, and the service personnel have nothing to do with it - they don't tweak the details and they don't even think of putting an uncertified fuel assembly into the reactor.

Normal background in the steppe, without human intervention, about 3-4 mcr / hour. It is a perfectly clean place. Therefore, at 9 mcr / h, the station is somehow not believed, especially in the area of ​​the storage and reactor halls. It is necessary to choose a particularly purged place on the territory of the NPP, but then we are not talking about the territory of the NPP itself. This is actually data from the surrounding area.

As a turbine equipment crawler, I’ll say that there is nothing serious here. Damage to the reactor has nothing to do. Although, if the cooling is hydrogen, it could have fallen.

The generator will jump off the load, the hydrogen wedge will stop holding, the blade will break off on the turbine, even just, the transformer will run out of power, there’s nowhere to put energy in, are you sure there will be enough staff to emergency shut down the reactor? What will the whole relay work as it should, so that all emergency pumps are operational? This is not Russia in the 90s, in the 90s in Russia there were still trained engineers and technicians.

Everyone who sat and pushed in the toilets at the power plant experienced sudden relief. I worked on the territory of the thermal power station, when the generator flew off the load, only the sound is worse when you work behind the flags on the input machines, while the generator on duty decides to check their operability.
