The Unit 1 reactor at the North Anna nuclear power plant in Virginia had to be shut down on Monday due to a leaking steam line. The problem has now been fixed, and the reactor is ramping up again. It was listed at 8 per cent output on this morning’s NRC Reactor Status Report.
The most disturbing thing about the incident is that, although the leak occurred on Monday, nothing about the problem has appeared on the NRC’s Event Report page. There is also nothing about the problem on the NRC’s list of Preliminary Notifications.
Aside from some local television coverage, and that after the fact, there have been no media reports about the incident.
WTOP Radio added this comment:
It is the second partial shutdown since the August 5.8 magnitude earthquake that knocked both reactors off-line and raised concerns about the plant’s safety.
But the NRC spokesman says there’s no evidence right now that this latest incident had anything to do with quake damage.
North Anna is located in Louisa County about 90 miles from Washington. It has operated since the 1970s.
During the August earthquake, there was some damage to buildings at the site but no off-site radiation leak. The reactors were restarted in November after an investigation found no functional damage.
