4OA3 Followup of Events and Notices of Enforcement Discretion

.1 (Closed) LER 05000461/2007-002-00, Improper Installation of Stanchions in

Containment Pool Swell Zone The licensee failed to adequately secure four radiation protection (RP) stanchions to the deck grating at the 755' elevation in the containment building, which could have affected the function of safety-related equipment following a design basis accident. Contrary to procedure CPS 1019.05, Transient Equipment/Materials, Step 8.5.3, the four stanchions were secured to the deck grating with plastic tie-wraps instead of metal grating clips. The licensee performed evaluation EC 365177, Review of Design Basis of RP Stanchions in Containment, and concluded that the tie-wraps would not be able to withstand the force of suppression pool swell. The licensee identified two containment isolation valves (1FC007, Spent Fuel Pool Cooling and Cleanup Containment Outlet Inboard Isolation Valve and 1FP053, Fire Protection Containment Inboard Isolation Valve) that could have been affected by a stanchion missile hazard.

The licensees evaluation conservatively assumed that the missiles created could impinge on the two containment isolation valves and prevent their containment isolation function. It was also determined that during a loss of offsite power/loss of coolant accident, containment isolation could only be assured if the Division 1 diesel generator was operable during the time the stanchions were in place. The licensee reported this event as a condition that could have prevented fulfillment of the containment isolation system safety function in accordance with 10 CFR 50.73(a)(2)(v)(D). The performance issue related to this event was discussed in NRC Inspection Report 05000461/2007007.

The NRC issued a Non-Cited Violation associated with a Green inspection finding for the licensees failure to assure that activities affecting quality were accomplished in accordance with prescribed documented instructions, procedures, or drawings. The inspectors determined that the information provided in LER 05000461/2007-002-00 did not raise any new issues or change the conclusions of the previous review.

LER 05000461/2007-002-00 is closed.

This inspection constituted one event follow-up inspection sample as defined by Inspection Procedure 71153.

4OA5 Other Activities

.1 Quarterly Resident Inspector Observations of Security Personnel and Activities
