NRC Notifies Nuclear Plant Owners of Seismic Equipment Issues During Earthquake Near North Anna
An investigation by the Nuclear Regulatory Commission found that some seismic equipment briefly stopped working at Virginia's North Anna nuclear plant during an earthquake in 2011.No damage occurred, reactor safety systems performed as designed, and both units at the Dominion plant shut down automatically during the 5.8 magnitude quake and power outage. But for eight seconds while emergency diesel generators powered up, part of the control room seismic monitoring equipment shut off because it was not connected to an uninterruptible power supply, the NRC reported in an information notice released Tuesday.http://nuclearstreet.com/nuclear_power_industry_news/b/nuclear_power_news/archive/2013/02/07/nrc-notifies-nuclear-plant-owners-of-seismic-equipment-issues-during-earthquake-near-north-anna-020701.aspx
