| Title | Performance of Operations with Potential to Drain the Reactor Vessel (OPDRV) Without Secondary Containment |
| Description | The inspectors reviewed this LER for potential performance deficiencies and/or violations of regulatory requirements. In February 2017, during the Unit 2 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. 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 2 refueling outage. LER 05000366/2017-001- 00 is closed. Description: The inspectors reviewed the plants implementation of Enforcement Guidance Memorandum 11-003 during maintenance activities which had the potential to drain the reactor vessel during the Unit 2 refueling outage. The activities were: Local power range monitors removal and replacement February 10, 2017; Control rod drive insert / recouple activity February 11, 2017; and Hydraulic Control Unit Venting February 12-13, 2017. 15 These activities took place without secondary containment being operable. Inspectors verified compliance with the guidelines of Enforcement Guidance Memorandum 11-003 prior to and during these activities. This condition was documented in the licensees corrective action program as CR 10329405, 10329857, 10330152, and 10330153. Enforcement: Unit 2 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 containment was inoperable. The NRC is exercising enforcement discretion (Enforcement Action (EA)-17-124) 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 the license amendment request which was submitted on April 20, 2017. |
