The third power unit it is southern-the Ukrainian nuclear power plant (NPP), on which the fuel is used in the American organization of Westinghouse, are off Thursday because of issues with equipment, informs " Energoatom ".
last Saturday auto-protect turned off the generator at the 3rd power unit it is southern-the Ukrainian nuclear power plant. According to the station, this incident had no connection with the operation of the Westinghouse fuel.
According to the Firm, after conducting recovery and high-voltage testing of the excitation system of the generator in the night of Tuesday, the Third unit of South-Ukrainian NPP was connected to the grid. However, the station had problems again, and the unit had to disable.
"The fourteenth of April, If you increase the power unit to 400 MW was found a defect on the equipment unit's turbine division? 3 - abnormality in the control valve supplying steam to the moisture separator-reheater. 05. 36 unit? 3 is southern-the Ukrainian nuclear power plant disconnected from the grid for the current recovery, "according to the report" Enegroatom ".
Transients on the power unit? 3 violations of conditions and limits of safe operation was not. The equipment of the first and second power units of the NPP works without remarks in the set mode. The radiation background on the industrial site of the NPP is at the level of natural background values, which were measured before start-up of a nuclear power station. Emissions and discharges of radioactive substances into the environment do not exceed the specified permissible values.
NPP is situated on the banks of the southern bug in Yuzhnoukrainsk the Nikolaev area. The station has 3 nuclear power unit VVER-1000 reactors with a total installed electrical capacity of 3000 MW.
A few years ago at the Czech Temelin NPP there was a depressurization of fuel elements production Westinghouse, after which the Czech Republic did not want services from this supplier. In 2012-2013 2 units of the South-Ukrainian NPP were violations in the work of the fuel assemblies of American manufacturing. It turned out that these violations were caused by structural defects in Westinghouse.
Despite this, in 2014 Ukraine and Westinghouse have agreed on the supply of American nuclear fuel for certain units of Ukrainian NPPs by 2020 (the main supplier of fuel for Ukrainian nuclear power plants is currently the Russian Firm TVEL). Experts believe that in Ukraine Westinghouse operate only within its own business interests, and see in the decision of Kiev to apply for Ukrainian nuclear power plants American fuel the danger of nuclear safety in the field.
