A series of incidents at Ukrainian NPPs lately

48
It's no secret that the nuclear industry in Ukraine is in crisis. The main problem of the Ukrainian nuclear industry is obsolete equipment that is used at local nuclear power plants. However, due to the negative attitude of Ukrainian officials towards Russia, the purchase of modern Russian counterparts, which could replace the existing equipment, is not possible, and the American and European equipment is too expensive and not always suitable for safe operation on the Ukrainian technological base.




Over the past year, a great number of emergencies and other incidents have occurred at the Ukrainian NPPs. For example, only in January 2018 of the year at the three nuclear power plants there was an unplanned shutdown of equipment, including the main equipment of power units. 11 January 2018 protection at the South-Ukrainian NPP (YuAES) protection turned off the main circulation pump, as a result of which the power of the third power unit fell by almost half. On January 19, the second power unit of the Rovno NPP was disconnected from the grid by the protection system due to the de-energization of the regulation organs of the reactor protection control system, shut-off valves landed and the TG-5 turbo-generator disconnected, the capacity of the unit decreased by more than 60%. 3 January at Khmelnitsky NPP (KhNPP) the second power unit was shut down, the technical failure of the sealing surface of the CPS drive was the cause of the shutdown; in other words, there was a leak. According to experts, the accident does not carry any threat to the public, and the radiation background near power plants is at a safe level.

1 February 2018 of the year an incident occurred that was not related to accidents at Ukrainian NPPs: Sergey Klimov, head of the nuclear safety department at Zaporizhzhya NPP (ZAES), was found dead. According to media reports, suicide was committed. At the time of his death he was 62 of the year.

In March last year, the Ukrainian police opened a criminal case on the fact of unauthorized interference with the work of computer networks of ZNPP. There was a leak of information due to the intervention. The incident became known back in December 2017. According to some information, three employees of the nuclear safety department of ZNPP, including the head of the department, became the perpetrators.

3 April 2018 of the year at KhNPP, the first power unit was disconnected due to the operation of the generator protection system. June 8 at the station was disconnected from the network of the second unit, the reason was the closing of the turbine stop valves. On November 17, the same power unit was shut down to conduct vibration adjustment of the turbo-generator. December 13 at KhNPP was detected damage to the phase B excitation transformer, as a result of which the second unit was disconnected from the network. At that time, the operation of both units of the power plant was stopped.

23 of September last year, the second power unit of ZNPP was shut off to eliminate the defect in the pipeline of the atomic circuit of the main circulation pump.

October 18 XUUME was disconnected from the grid by the third power unit due to a malfunction of the turbine automatic control system.

December 22, the first power unit of the RNPP was disconnected from the network due to an incorrectly generated signal of the automatic protection of the pressure drop in the core of the reactor installation.

A series of blackouts spread smoothly to the 2019 year.

So, already 18 on January 2019 of the year at the Rovno NPP, the power unit was again disconnected with the stop valves landing and the TG-5 turbine generator disconnected, but this time the third power unit was disconnected from the network.

In addition to numerous malfunctions at Ukrainian NPPs, the facts of embezzlement of money by officials of power plants are known.

In January of this year, Ukrainian police officers exposed the fact of appropriation of money at the Zaporizhzhya NPP for a total of 1,3 million hryvnia. According to media reports, two employees of the power plant signed an agreement with the director of the company for the supply of natural mineral materials. Under the guise of fulfilling the terms of the contract, they entered false information in the documents and appropriated ZNPP money.

Currently, Ukraine has 15 operating reactors at four nuclear power plants. 10 reactors have already served a warranty period, and for a few more, the warranty period ends two years later. Of concern is the fact that experiments with western nuclear fuel are continuing in a number of reactors, for which power units of the Soviet development were not designed initially.

    God forbid, one more Chernobyl will fall to everyone on the site of Ukrainians. It is better to give all nuclear power plants under the control of the IAEA and other international organizations in order to drive loot from the West to improve nuclear energy in the country.

      The IAEA has long been an organization that ensures the safety of nuclear power plants in the world. Now it is an organization for espionage and pressure on countries that NATO does not like. Only. No one will upgrade the Ukrainian nuclear power plant. And it’s good if they only demolish everything and sell electricity to Ukraine from abroad.

      But I won’t be surprised if, intentionally, accidents are arranged with the expectation that as many people as possible covered with radiation. It is necessary for them to collect statistics on how radiation affects people with mass, rather than laboratory, single use.

    At the UN Security Council it is necessary to raise the question of closing the nuclear power plant on the outskirts. This is a threat to the world and not an internal problem of the Selyuk. Let the European Union give them money to close. All the same, they want to be an agricultural superpower, let them drown

    And in Kazakhstan, they decided to refuse Putin’s “present” in the form of nuclear power plants, it makes no sense. Having a state district power station on the cheapest coal from Ekibastuz completely covers our need, moreover, we can export excesses. Before that we can go to Russia, now to China.

      Emissions of radionuclides with coal combustion products will be larger than those of a nuclear power plant operating in normal mode. True, if the power station is fucking, then the consequences will be much less.

            Well, right, what should we do with grants from the global economy?
            But the runway in 2018 grew by 4.1% compared to the previous year. In 17, it was 159,4 billion USD (2017), compared to Uzbekistan 48,72 billion USD
            And those nuclear plants were going to build, probably soon they will overtake us.

              Igor, the share of the MCP cost in the cost of the entire power unit is very significant and is simply prohibitive for the Ukrainian NJSC Energoatom. And the replacement of the MCC at the power unit, even if there is a spare one, is a real feat commensurate with the almost partial opening of the reactor core, and which no one will do in Ukraine ...

        According to experts, after Chernobyl, conclusions were drawn and the means of emergency shutdown of the reactor were made constructively providing operation when the generator was stopped without human intervention. Much more complicated with the turbine and electrical parts, but they can not give the Chernobyl effect in principle upon failure.

          After Chernobyl, they tried to minimize the risks of uncontrolled acceleration of a fast neutron reactor, and this was largely done. But if the staff wants to repeat the "success" of the Chernobyl nuclear power plant, then no automation will stop it ... The Chernobyl nuclear power plant also had good protection and the buttons to turn it off did not exist at all, but in the fight against automation, on the orders of the Central Committee in Moscow, the station personnel showed soldiers ingenuity - wedged the necessary relays with matches and fixed certain buttons with adhesive tape in the right position for the staff and the automation was defeated ... Truly the iron will of the authorities, works wonders ....

              Not everything here I agree with you. A sabotage is when the purpose of the station’s personnel’s actions will be the explosion of the reactor itself, and if the goal is to carry out some necessary and useful experiment (as at the Chernobyl NPP in 1986) or just the need to prevent deenergizing of the plants of some Ukrainian oligarch, then this is already there will be just negligence ... The result will of course be the same, but the motives are completely different ...

    I read this! (On January 3, the second power unit was stopped at the Khmelnitsky NPP (Khmelnitsky NPP), the cause of the stop was a technical malfunction of the sealing surface of the CPS drive, in other words, there was a leak.) The author most likely does not represent the design of the reactor and what is this CPS and what is the failure of the sealing drive surface of this very CPS.
    P.S. CPS is a reactor protection control system. If we talk about the sealing surface of the drive CPS, then it is outside the active zone, well, all of a sudden! And the stop is made in order to avoid the off-design behavior of the absorbing rods, because in case of leakage, unplanned subsidence and spontaneous extinguishing of the reactor are possible. It has nothing criminal and close with a leak from the core. So in other cases.
    The author teach the materiel before that thread write with a smart look;)

    Nuclear plant workers who live close to their place of work with their families are not fools either.
    I think that in case of serious problems they will simply drown all the fuck in order to prevent the bad.
    In the meantime, all accidents concern the periphery and have nothing to do with reactors.
    But when there is a blanking of the active zone, then it’s worth it to strain everyone, yes.
