UNITED STATES NUCLEAR REGULATORY COMMISSION WASH.INGTON, D.C. 20555-0001 Mr. Richard M. Glover H. B. Robinson Steam Electric Plant Site Vice President Duke Energy 3581 West Entrance Road Hartsville, SC 29550 December 1, 2014
SUBJECT:
H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2-REQUEST FOR ADDITIONAL INFORMATION REGARDING REVISION TO TECHNICAL SPECIFICATION 3.8.1, PROPOSED CHANGES TO DIESEL GENERATOR TESTING REQUIREMENTS (TAC NO. MF2717)
Dear Mr. Glover:
By letter dated September 10, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13261A289), supplemented by letters dated January 30, 2014 (ADAMS Accession No. ML14037A105), and June 1, 2014 (ADAMS Accession No. ML14163A480), Duke Energy Progress, Inc. (the licensee), requested an amendment to Renewed Facility Operating License No. DPR-23 for H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP). The proposed license amendment will modify the current HBRSEP Required Actions B.3.1, B.3.2.1, and B.3.2.2 of Technical Specification 3.8.1, "AC Sources-Operating."
The U.S. Nuclear Regulatory Commission staff has reviewed the licensee's submittal and determined that additional information is needed in order to complete its review. The enclosed document describes this request for additional information (RAI). The RAI was e-mailed to the licensee in draft form on November 5, 2014 (ADAMS Accession No. ML14315A086), with a response requested by December 22, 2014.
If you have any questions, please contact me at 301-415-2760, or by e-mail at Martha. Barillas@nrc.gov.

REQUEST FOR ADDITIONAL INFORMATION H. B. ROBINSON STEAM ELECTRIC PLANT. UNIT NO.2 REVISION TO TECHNICAL SPECIFICATION 3.
8.1 PROPOSED CHANGE
S TO DIESEL GENERATOR TESTING REQUIREMENTS DOCKET NO. 50-261 By letter dated September 10, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13261A289), as supplemented by letters dated January 30, 2014 (ADAMS Accession No. ML14037A105), and June 1, 2014 (ADAMS Accession No. ML14163A480), Duke Energy Progress, Inc. (the licensee), requested an amendment to Renewed Facility Operating License No. DPR-23 for H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP). The proposed license amendment will modify the current HBRSEP Required Actions (RAs) B.3.1, B.3.2.1, and B.3.2.2 of Technical Specification (TS) 3.8.1, "AC Sources-Operating." The RAs specify that Surveillance Requirement (SR) 3.8.1.2 be performed or an assessment to rule out common cause failure along with the SR when one Diesel Generator (DG) is determined inoperable. The proposed change will modify the RAs with a note that states, "Not required to be performed if the cause of the inoperable DG is solely due to pre-planned maintenance or Surveillance testing."
Title 10 of the Code of Federal Regulations 50.36(a)(1) states, in part: "A summary statement of the bases or reason for such specifications, other than those covering administrative controls, shall also be included in the application, but shall not become part of the Technical Specifications." The licensee submitted a response dated June 1, 2014, to the U.S. Nuclear Regulatory Commission staff's request for additional information (RAI). The response shows a mismatch of information between the TS and Bases. Clarification is requested such that the TS clearly provides the RAs, and the Bases provide amplifying information only.
STSB RAI-3 In the license amendment request dated September 10, 2013, Section 1.0, "Summary Description," paragraph 2 states, in part:
The Note will exempt performance of this conditional surveillance when the cause of the initial inoperability of the inoperable DG is pre-planned maintenance and testing. The exemption will not apply whenever the cause of the inoperability is corrective maintenance, even if the problem required corrective maintenance is discovered during the execution of the original pre-planned maintenance and testing.
Clarify TS 3.8.1, RAs B.3.1, B.3.2.1, and B.3.2.2 to indicate the circumstances under which Condition B must be initially entered and re-entered for correct maintenance issues identified during preventative maintenance activities.
Enclosure STSB RAI-4 In the RAI response dated June 1, 2014, the following inconsistencies have been identified:
The mark-up page indicates the Note will be positioned above the "AND." On the clean page, the Note is below the "AND."
According to the Bases 3.8.1 Insert 1, "A NOTE has been added to take exception to perform REQUIRED ACTION 8.3.1 or 8.3.2... " In Standard Technical Specifications, a Note only applies to the Required Action directly below it, unless directly specified in the Note. Therefore, the Note only applies to 8.3.1. Please clarify where the Note is applicable.
Clarify corrections to the mark-up and clean pages so that the intent of the TS is clear.
STSB RAI-5 In the RAI response dated June 1, 2014, only the proposed TS pages were submitted. Please revise your submittal to reflect a description and evaluation of all proposed changes to the TS.
