Permanent repair. In Ukraine, the power unit of one of the NPPs is shut down again

Obviously more frequent repairs at Ukrainian nuclear power plants give reason to think about the reliability of the system amid reports of the transition of Ukrainian NPPs to American-made fuel assemblies. This time it became known about the shutdown of one of the units at the South-Ukrainian NPP. The site of the NPP itself reports that the order to shut down the 3 unit of the station came from the Ministry of Energy and Coal Industry of Ukraine as early as September last year, and therefore the disconnection to “repair” is “planned”.

The reactor is disconnected from the system for more than three months - on 104 days. At the same time, it is reported in the material of the press service of the NPP that during the “repair” full discharge from the reactor core will be performed. The following procedures are also provided:

- overhaul, operational control of the metal, technical certification:
- main circulation pump №1;
- steam generators No.1 and No.2;
- heat exchangers for emergency cooling down of the first and second security systems;
- heat exchangers;
- high pressure heaters;
- control of heat exchange tubes of steam generators No.1-4 with jamming of defective tubes;
- control of welded joints of steam generators No.1-4,
- overhaul of pumps, tanks, valves of the first and second security systems;
- average repair of a turbogenerator;
- overhaul of diesel generator №5;
- overhaul of generator number XXUMX of the first security system;
- average repair of generator No. 2 of the second security system;
- current repairs of the block transformer, start-up and backup transformers, auxiliary transformer;
- operational control of the metal and technical certification of equipment and pipelines of the reactor and turbine departments;
- reconstruction of equipment, including:
- modernization of the reactor core emergency cooling system;
- modernization of the emergency power supply system;
- replacement of narrowing devices for measuring water consumption for steam generators;
- development and implementation of measures to reduce the hydrogen concentration in the containment for beyond design basis accidents and others.

About what kind of fuel will be loaded into the reactor core after the "scheduled maintenance" is not reported.

Will they have an “unplanned Fukushima”?

[Victor jnnjdfy]

Scheduled overhauls are carried out in the spring season. Plan them in advance. In the Russian Federation as well. Why write nonsense?

[bazzbazz]

All right! Let them repair, do, watch! I want to control Ukraine. But not in this area, because if an accident, then it can fly all of Europe and us!

[tihonmarine]

Everyone is repairing, there is nothing surprising. Of course, if there’s enough pennies on a TVEL, of course, the cheapest or second-hand ones will be taken.

[aszzz888]

About which one fuel will be loaded into the reactor core after a "scheduled repair", not reported.

And so it is clear, they will push Merikatosovskoye ....

[210ox]

Let’s compare with the work schedules of our stations .. That would be more objective. I appeal to the author.

[novel66]

logically, everything is true, but you expect a trick from the brothers, even when they seem to do everything

[210ox]

Roman, I worked for twelve years at a power plant, although it’s thermal. Of course, the requirements are the highest for both personnel and operating rules. I’m more than sure that Ukraine is the same .. Surely, apart from repairs and equipment upgrades, well, Amerz assemblies ... It is not so difficult to make a copy of Soviet TVELs, and I think there will be no problems with the selection of fuel. Nobody has come up with the truth about protection from a fool .. Especially from a drunk fool. An explosion in 1992 at Smolenskaya TPP2 shows this. .

Something a little weird scheduled repairs. In fact, the work is concerned specifically with the emergency systems of the reactor, and not with the technological chain of energy generation. It looks like preparation for loading non-standard fuel or similar experiments with fuel

[sgr291158]

Slowly but surely, Chernobl scrambles.

In Ukraine, the power unit of one of the nuclear power plants is again turned off

Judging by the Ukrainian TV from Kiev, everyone got a hell of a hell, the center is closed both of cars and people, units are like on a provincial collective farm, I look at Kiev life on the webcam and I wonder if maybe they are preparing for the third world war (in the light of the latest Jewish-American attacks on Syria) , all the rats escaped from the city ...

[Fedorov]

There are just jokes. No need to joke. I myself was agitated. Yet in 1996.

[ul_vitalii]

Yes, every item whose poor performance can cause an emergency.

[BAI]

[quote] overhaul, operational control of metal, technical inspection:

- heat exchangers for emergency cooling down of the first and second security systems;

- overhaul of pumps, tanks, valves of the first and second security systems;

- overhaul of generator number XXUMX of the first security system;
- average repair of generator No. 2 of the second security system;

Yes, they brought the station to the state of a bomb.

Oh, it’s not Westinghouse’s fuel, it’s over, a bunch of western-design PWR nuclear power plants are working fine, and our VVER belongs to this type of reactor. The previous assembly design had problems, this one works normally. With the same success we can say that the assembly of TVS-SQUARE for PWR western design from Rosatom will not be reliable in AZ reactors. In addition, Westinghouse is aimed not only at the Ukrainian NPP market, but also at other countries that have Soviet / Russian design reactors.

It seems to me the matter is more in the deterioration of equipment, so frequent repairs. Although KIUM would look Ukrainian blocks would be interesting.

Yes, and VVER reactors are very reliable and I think their condition at KIUM will only be reflected, although this is a very painful topic because the reactors in Ukraine are breaking down, and Rosatom is carrying image losses. Well, it’s there and profitable because the sooner their nuclear power plants fail, the more accommodating Kiev will be, we are still waging a war)))

[konstantin68]

Play the ancient Sumerians with Westinghouse. This is not a joke even once.

[konstantin68]

Quote: NordOst16

for the reactors in Ukraine are breaking down, and the image losses are borne by Rosatom.

Where is the connection, explain? If you start pouring gasoline into your diesel Mercedes, what are the image losses of Daimler?

[Archivist Vasya]

Oh, or else it will be!

[gloomy fox]

that is not ok there, since such a scheduled repair.

[Zomanus]

Well, the nuclear scientists who serve these reactors are not fools either.
And rather they will drown them out completely, rather than allow accidents.
Well, it's just a major inspection with a troubleshooting,
just because the equipment is badly worn.
And the further, the more often such inspections will be.
