Maryland nuke shut down following leak in monitoring system just reported:

A leak from a monitoring instrument line on Calvert Cliffs Nuclear Power Plant Unit 1 resulted in the second shutdown of the unit in the same week.

The leak from a reactor coolant pump differential-pressure sensing line, which is for monitoring purposes only, was first noticed July 17, according to a news release from Neil Sheehan, a Nuclear Regulatory Commission public affairs officer.

After the initial leak, Constellation Energy Nuclear Group shut down the unit for maintenance. However, during a check Saturday, plant spokesman Kory Raftery said, the crews noticed the same small drip. The unit again was shut down, and maintenance crews are “replacing the whole [tubing],” Raftery said.

Calvert Cliffs’ two pressurized water reactors came online in 1975 and 1977, and are scheduled to run through 2034 and 2036, thanks to an NRC license extension.
