“As part of the investigation, the head of the boiler and turbine workshop of the TPP-3 of NTEC JSC was detained as a suspect,” the statement said.

Earlier, the head of the Ministry of Emergencies, Yevgeny Zinichev, at a meeting with President Vladimir Putin reported that the reason for the depressurization of the diesel fuel storage tank at the TPP was the sinking of the foundation piles.

Putin supported the minister’s proposal to declare a federal emergency in the leak zone.

The incident occurred on May 29.
