REQUEST FOR ADDITIONAL INFORMATION REGARDING CHANGE TO SURVEILLANCE REQUIREMENT 3.8.2.1 H.B. ROBINSON UNIT NO. 2 DOCKET NO. 50-261 (EPID NO. L-2019-LLA-0119)
By application dated June 4, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19155A037, Duke Energy (the licensee) requested a license amendment to revise the H.B. Robinson Steam Electric Plant Unit 2 (HBRSEP), Technical Specification (TS) 3.8.2, AC Sources - Shutdown, Surveillance Requirement (SR) 3.8.2.1.
The SR change would reflect that HBRSEP SR 3.8.1.18 is not required to be met in the TS 3.8.2 Applicability.
The U.S. Nuclear Regulatory Commission (NRC) staff has determined that the following additional information is needed to complete its review.
Regulatory Requirement Title 10 of Code of Federal Regulations (CFR) 50.36, Technical specifications, establishes the requirements related to the content of the TS. Pursuant to 10 CFR 50.36(c) TS are required to include items in five specific categories related to station operation: (1) Safety limits, limiting safety system settings, and limiting control settings, (2) Limited conditions of operation (LCOs),
(3) Surveillance requirements (SR), (4) Design features; and (5) Administrative controls. The proposed change in this LAR relates to the SR category.
Request for Additional Information (RAI) No. 1 In the LAR, Enclosure 1, Page 2, the licensee stated: Both the 115 kV and 230 kV startup transformers are capable of energizing Emergency Buses E1 and E2. Should a failure of either startup transformer occur, the other startup transformer would be capable of supplying power to the onsite distribution system. A manual transfer is made to the alternate offsite circuit upon a loss of either startup transformer.
The NRC staff has identified the following discrepancy:
The LAR does not clearly describe the alternate offsite circuits that would be used to supply power upon loss of a startup transformer. In addition, it is not clear that offsite power will remain available (uninterrupted) to at least one of the emergency buses while switching to alternate offsite circuit during various switching operations.
The staff requests the following information to address this discrepancy:
Please provide a description or highlighted drawings showing the offsite power circuits to the Emergency Buses E1 and E2 under the following operating configurations when (a) Unit is operating at 100 percent power (b) Unit is tripped:
(i) Both 115 kV and 230 kV startup transformers available
(ii) 115 kV startup transformer out-of-service (iii) 230 kV startup transformer out-of-service For each configuration, please explain which circuit (line-up) is considered a normal offsite circuit and which circuit (line-up) is considered an alternate offsite circuit. Also, please confirm whether offsite power will remain available (uninterrupted) to at least one of the emergency buses while switching to alternate offsite circuit during various switching operations.
