Slovenia's NEK gears up for Krsko NPP relaunch

The welding of the second new segment of the plant's piping system in the so-called valve room in the containment temple was completed and the quality of the work was confirmed by non-destructive methods, NEK said in a statement earlier this week.

The operator is currently moving 121 fuel elements from the spent fuel pool back into the reactor vessel, which will be followed by warming up the systems and verifying their operation, 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.
