The block’s operation stalled automatically in line with nuclear safety regulations defined in a contingency plan prepared in advance for such eventualities, the office said.

An investigation of a team of experts is underway to establish what exactly had caused the malfunction and what sort of repair is necessary, it said.

The block will be restarted under the OAH’s supervision once the repair is completed, the office said. Antal Kovács, communications director of the company operating Paks, said Block 1 is expected to be reconnected to the entire network on Friday noon.

The block’s stoppage has not affected the operation of the other three blocks.
