SUMMARY

OF MARCH 13, 2017, PUBLIC MEETING WITH SOUTHERN NUCLEAR OPERATING COMPANY, INC., REGARDING LICENSE AMENDMENT REQUEST TO IMPLEMENT RISK-INFORMED TECHNICAL SPECIFICATION COMPLETION TIMES AT VOGTLE ELECTRIC GENERATING PLANT, UNITS 1 AND 2 (CAC NOS. ME9555 AND ME9556)

On March 13, 2017, the U.S. Nuclear Regulatory Commission (NRC) staff held a public teleconference 1 with staff from Southern Nuclear Operating Company Company, Inc. (SNC or the licensee). The purpose of the call was to discuss SNC's license amendment request to implement risk-informed Technical Specification Completion Times for the Vogtle Electric Generating Plant, Units 1 and 2. Specifically, the discussion was focused on draft request for additional information (RAI) question 6 that was provided to SNC on January 24, 2017. 2 Following a January 26, 2017, 3 public meeting, the NRC staff modified the question to enhance clarity and reissued the draft question to SNC on February 3, 2017. 4 Following a February 7, 2017, public meeting, 5 the NRC staff again provided revised RAls, including RAI 6 which deals with accounting for common-cause failure in emergent equipment failures to SNC. 6 This meeting focused on the response for RAI 6.

The licensee opened the meeting with a presentation addressing how risk management actions can impact risk and compared this impact to numerically adjusting the risk-informed Technical Specification Completion Times. 7 The NRC staff made a presentation that indicated the methods of addressing common-cause failure that were most likely to be successful. 8 1
