Nov. 18 — The first incident at the nuclear plant in Brunswick, North Carolina happened on Wednesday: Local TV: "They believe radioactive water is leaking from the top of the vessel" at North Carolina nuke plant -- Significant because it goes directly through reactor core (VIDEO)
Here is information on Thursday’s incident: NRC: Event Notification Report for November 18, 2011
UNANALYZED CONDITION ON STARTUP FOLLOWING MAINTENANCE OUTAGE
“On November 17, 2011, at 1345 Eastern Standard Time (EST), it was determined that an unanalyzed condition that significantly degraded plant safety existed on Unit 2 following a mid-cycle maintenance outage which required reactor vessel disassembly. Unit 2 had reached Mode 2 (i.e., Startup) during the power ascension, when elevated drywell leakage was identified and the plant was shutdown (see EN#47444). Unit 2 was subsequently operating in Mode 4 (i.e., Cold Shutdown) to allow for drywell entry. During leak investigation activities, it was determined that the reactor pressure vessel (RPV) head was not fully tensioned. This condition is being reported in accordance with 10 CFR 50.72(b)(3)(ii)(B) as a condition of the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety.
“The safety significance of this event was minimal. Unit 2 was in power ascension operating at a maximum of approximately 7% of rated thermal power. Control Room Operators took appropriate action to shutdown the Unit when elevated drywell leakage was identified.
“The NRC Senior Resident Inspector has been notified.”
“Environmentalists have questioned whether the leak might threaten the public or environment. However, officials said there is no need for concern.” -Local 14 News
