SAFETY CONSEQUENCES AND IMPLICATIONS
The OPDRVs discussed in this report were performed during the HCGS refueling outage (H1 R21) and were accomplished using the interim actions provided by the NRC in EGM 11-003, Revision 3.
For these events, HCGS adhered to the NRC plain language meaning of OPDRV activities that could potentially result in draining or siphoning the RPV water level below the top of fuel. HCGS 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 concurrences:
LER 2015-002-11, dated June 10, 2015, reported OPDRV activities during the 2015 refueling outage (H1 R19).
Interim actions in accordance with Revision 2 of the EGM were applied. No corrective actions were stated.
LER 2016-004-00, dated December 20, 2016, reported OPDRV activities during the 2016 refueling outage (H1 R20). Interim actions in accordance with Revision 3 of the EGM were applied. No corrective actions were stated.
CORRECTIVE ACTIONS
YEAR 2018 SEQUENTIAL NUMBER
- - 001 HCGS has submitted a license amendment request to adopt a Technical Specification Task Force (TTF) traveler associated with generic resolution of this issue.
REV NO.
- - 00 One of the two leaking relief valves was replaced during H1 R21. The second relief valve is scheduled for replacement during the next refueling outage.
