6th reactor building of the Novovoronezh nuclear power plant, that was built based on an experimental reactor VVER-1200, could only work a few weeks at full capacity until an accident occurred.
Locals reported a powerful explosion at the nuclear power plant, reports Russian ecological media Bellona.ru.
At the same time, Russian state-owned media traditionally kept extremely silent regarding the details of the incident. In particular, news agency RIA Novosti reported that “the 6th power unit of Novovoronezh nuclear power plant was disconnected from the grid due to failure of the power generator.” Meanwhile, independent environmental organizations found out that the problem is actually much more serious.
“Turning off the 6th unit at the night of November 10 was preceded by an explosion that smashed the turbine hall,” writes the local media “Notebook Voronezh”, citing eyewitness of the accident. “Alarm systems in all vehicles in the area were screaming for at least 15 minutes. The generator in the turbine hall of the 6th unit burned down beyond repair. Also, a transformer blown, and all electrics burned. A state commission is working at the station, the situation is an emergency.”
Employees of Novovoronezh NPP deny the information about an explosion. They say that a loud sound was caused by a fault trip.
“During the power test, an electrical generator failure occurred, which led to the shutdown of the power grid,” told a representative of Novovoronezh NPP administration on a condition of anonymity. “When you disconnect a power generator and a turbine, a system triggers that prevents building up pressure of the steam over the limit. The loud sound was caused by a rapid opening of valves.”
