| Title | Performance of Operations with Potential to Drain the Reactor Vessel (OPDRV) Without Secondary Containment |
| Description | In February 2016, during the Unit 1 refueling outage, operations with the potential to drain the reactor vessel (OPDRV) activities were performed while in Mode 5 (Refueling Mode) contrary to Technical Specification (TS) 3.6.4.1. These OPDRV activities were also performed during the Unit 2 Refueling Outage. Enforcement Guidance Memorandum (EGM) 11-003, Revision 3, provided required interim actions which were incorporated into procedure 31GO-OPS-025-0 Operations with the Potential to Drain the Reactor Vessel. This procedure was used during the OPDRV activities for the Unit 1 refueling outage. Enforcement: Unit 1 TS 3.6.4.1 required, in part, that activities that had the potential to drain the reactor vessel be conducted only with secondary containment operable. Contrary to that requirement, the licensee conducted activities that could cause the reactor vessel to drain while secondary was inoperable. The inspectors determined this was a Severity Level IV violation. The NRC is exercising enforcement discretion (Enforcement Action (EA)-16-158) in accordance with Section 3.5, Violations Involving Special Circumstances, of the NRC Enforcement Policy because the violation was identified during the discretion period described in Enforcement Guidance Memorandum 11-003. Therefore, the NRC will not issue enforcement action for this violation, subject to a timely license amendment request. |
