"The second unit was disconnected from the network at night on an urgent request to carry out routine maintenance on heat and power equipment. Repairs are underway as usual", - RIA Novosti quotes the words of its interlocutor at the station.
According to the source, the application was submitted due to the detected deviations in the operation of the power unit.
Rosenergoatom's telegram channel says that the soaring was detected due to a defect in the weld on the pipeline, which is related to the steam level and humidity control system in the steam generator. Non-radioactive water circulates along the "clean circuit" to which the system belongs.
Earlier it was reported that due to a steam leak, the second power unit at the Rostov NPP had to be turned off. The radiation background did not go beyond the normal range.
The incident was commented on by the president of the group of companies "City Center of Expertise" Alexander Moskalenko. He noted that if this vapor was formed in auxiliary mechanisms or in the second circuit of a nuclear installation, then this should not cause any concern, since there is no radiation there.
“It is dangerous if the fuel elements were destroyed and their contents got into the primary circuit and together with the water came out. But the probability of this is very small, since the condition of the fuel elements is continuously monitored”, - he commented.
Alexander Moskalenko added that Rosatom's costs for technical diagnostics of stations, including checking the condition of fuel elements, reach several billion rubles annually. In addition, the elements of the system are built in such a way that whatever happens there, they could not be destroyed for a long time and retain radiation inside, giving off heat.
We would like to remind that the Rostov NPP is a branch of Rosenergoatom (State Corporation Rosatom). In the period from 2001 to 2010, it was called "Volgodonskaya NPP". The station is located on the bank of the Tsimlyansk reservoir not far from Volgodonsk. This is the southernmost nuclear power plant in the country.
