BASIS FOR REPORT This event is reportable in accordance with 10 CFR 50.73(a)(2)(i)(B) as conditions prohibited by CNS TS 3.6.4.1, which prohibits performing activities identified as OPDRVs in MODE 5 while secondary containment is inoperable.
SAFETY SIGNIFICANCE
As discussed in EGM 11-003, Revision 2, enforcement discretion is appropriate because the issues have low safety significance since licensees must implement compensatory measures to provide an adequate level of safety when using the discretion. To ensure compliance with the interim actions specified in the EGM, CNS added guidance to plant procedure 0.50.5. This procedure was implemented for the OPDRV activities during which secondary containment was not operable.
CAUSE
Implementation of EGM 11-003, Revision 2, during RE-28 was a planned activity. As such, there were no root cause evaluations of the events.
CORRECTIVE ACTION
CNS will submit a license amendment request to adopt the Technical Specifications Task Force (TSTF) traveler associated with generic resolution of this issue, within 12 months after issuance of the Notice of Availability of the TSTF traveler.
PREVIOUS EVENTS There have been no events reported in the last three years related to EGM 11-003 or OPDRVs.
