An automatic shutdown of the power unit occurred at the Zaporizhzhya NPP

At the most powerful in Ukraine Zaporizhzhya nuclear power plant, the second power unit was automatically turned off. This was recorded during a test test of the electrical system.

This message appeared on the official website of the Zaporizhzhya NPP.



The second power unit has just undergone scheduled maintenance and has been disconnected from the power system. Automation worked and blocked its work after two hours. Apparently, it was "not repaired".

It happened this morning. After the repair, the unit was connected at 5:47 Kiev time, and exactly two hours later the protection responded. Now a group of engineers at the nuclear power plant is investigating the causes of the accident.


It is said to have had no impact on the operation of the other five units, which continue to function normally. As noted by the press service of the station, no problems were found either with this equipment or with its operating personnel. The radiation situation at the NPP and the adjacent territory remains normal, the radiation level corresponds to the natural background. At the same time, what could have caused the automation to be turned on is still unknown. They don't talk about the reasons.


The Zaporizhzhya Nuclear Power Plant (ZNPP) is considered the largest energy facility in Europe. Its first power unit began operation in 1984.

    This incident, by the way, is not terrible, the automation worked well. It often happens, as a matter of principle, it is better to play it safe.
    But yesterday there was an accident at the seventh power unit of the Burshtyn TPP. Explosion of a gas-vapor mixture. Much more trouble, now the unit will go to repair

              Have they already downloaded the "pencils" from "Westinghouse" or are they just going? Somehow I missed it. If you have time, then this is only the first swallow.

          So things there are now very unimportant with the energy balance .. And by the way, the return of the unit from the planned repairs should have corrected them. According to the plan, after that, a unit at the Rivne NPP was supposed to undergo scheduled repairs, if it were "held back" a little longer in Ukraine there would be a record number of simultaneously operating units .. it is clear that it will not be long .. the unit of the Zaporizhzhya station will be launched normally and stopped at Rivne ...

            Repairs are performed by many services. For example, I worked in the thermal automation workshop at a thermal power plant. A similar service at a nuclear power plant seems to belong to the electronics and automation department. Perhaps she was in a hurry, something was not completed. There may be a bunch of reasons.

      So it is always not scary until it explodes. Ukraine is gradually getting used to not paying attention to emergency situations. And the result is, according to Chernomyrdin: "But this has never happened, and now again" God forbid, of course.

        A bankrupt is not a liquidated or preserved enterprise. He may well not even turn off the equipment and pay salaries. It's just that he is not able to pay off his debts - this is such an official legal status and not the state of technological processes.

            Salaries are not paid from profits. Big business signs contracts for many years and decades, and even the debtor can have money for salaries from their execution. He can ship finished products under short-term contracts on the principle of "commodity-money", look for new owners who are ready to pay off their debts, government subsidies, business managers. The nuclear division that formed Westinghouse Electric Company LLC has not yet been liquidated, despite the fact that it is bankrupt, and even has a live website - https://www.westinghousenuclear.com/

                        There is also a certain difference in cultural and economic mentality.
                        They exist, these cultural differences - for example, in the Western tradition there is a tradition of depicting a lingual "green man" in temple architecture, and we have never added goblin to religious buildings. So it is in the economy - for at least a little promising and progressive enterprises, their managers are fighting to the end.
                        The introduction of collateral systems in case of bankruptcy would help us - you cannot liquidate an enterprise without depositing your own money as collateral at the market value of analogues of such an enterprise in the world market. Accordingly, if the plant was simply cut down, then they won’t get the money back.

      It seems like in the article it is written that it was passing tests after a major overhaul.

      And it's just that emergency shutdowns due to the operation of the automatic system occur quite often.

      When the worst starts to come true at a nuclear power plant, it looks like Chernobyl, Fukushima or Three Mile Island.

      Of course, the safety of NPP operation in Ukraine raises very big concerns, but you should not panic for any reason.
