CAUSE OF EVENT

Implementation of EGM 11-003, Revision 1, interim actions during the HGGS refueling outage (H1 R18) was a planned activity. As such, no cause determination was performed for the event.

SAFETY CONSEQUENCES AND IMPLICATIONS

The OPDRVs discussed in this report were performed during the HGGS refueling outage (H1R18) and were accomplished using the interim actions provided by the NRG in EGM 11-003, Revision 1. For these events, HGGS adhered to the NRG plain language meaning of OPDRV activities that could potentially result in draining or siphoning the RPV water level below the top of fuel. This included evolutions involving aligning and realigning plant systems prior to achieving steady-state water level control, without taking credit for mitigating measures. HGGS also met the requirements that specify the minimum makeup flow rate and water inventory based on OPDRV activities with long drain down times. Further, an adequate defense in depth was maintained to minimize the potential for the release of fission products with secondary containment not operable by (a) monitoring RPV level to identify the onset of a loss of inventory event, (b) maintaining the capability to isolate the potential leakage paths, (c) prohibiting Mode 4 (cold shutdown) OPDRV activities, and (d) prohibiting movement of irradiated fuel with the spent fuel storage pool gates removed in Mode 5. All other Mode 5 TS requirements for activities were followed.

Since these compensatory measures were properly implemented, an adequate level of safety was provided during the OPDRV activities described in this report. Based on this information, the performance of these OPDRV activities were determined to have a low safety significance.

PREVIOUS EVENTS A review of Licensee Event Reports and the corrective action program for the past three years identified the following previous similar occurrences.

LER 2012-003-00, dated May 5, 2012, reported an OPDRV activity during the 2012 refueling outage (H1R17). Interim actions in accordance with Revision 0 of the EGM were applied. No corrective actions were stated.

CORRECTIVE ACTIONS

HGGS will submit a license amendment request to adopt a Technical Specification Task Force (TSTF) traveler associated with generic resolution of this issue, within four months after the issuance of the Notice of Availability of the TSTF traveler.

COMMITMENTS

This LER contains no regulatory commitments.
