NEK to reconnect Krsko NPP to grid by end-week

"The primary cooling circuit is closed and refilled with water, the primary pumps are started, the heating of the primary system has started, and the reactor will be started next," NEK said in a statement on Monday.

Slovenia's nuclear safety agency has confirmed that NEK implemented all necessary and expected measures and thereby fulfilled the prerequisites for the safe operation of the power plant, the company said.

The operator has moved 121 fuel elements from the spent fuel pool back into the reactor vessel, NEK noted.

NEK shut down Krsko on October 5, after a leakage was detected in the primary system within the containment structure. The malfunction falls below the specified limit in technical regulations and poses no threat to the safety of employees, the public, or the environment, NEK said back then.

The facility operates a single Westinghouse pressurised light water reactor with a thermal power capacity of 2,000 MW.
