UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Mr. William R. Gideon Site Vice President H. B. Robinson Steam Electric Plant Duke Energy Progress, Inc.
3581 West Entrance Road Hartsville, SC 29550 July 8, 2014
SUBJECT:
H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT 2-REQUEST FOR ADDITIONAL INFORMATION REGARDING TECHNICAL SPECIFICATION 3.1.7 DELETION OF MONTHLY ROD POSITION INDICATION SURVEILLANCE REQUIREMENTS (TAC NO. MF1966)
Dear Mr. Gideon:
By letter dated June 7, 2013 (Agencywide Documents Access and Management System Accession No. ML13182A019), Duke Energy Progress, Inc. (the licensee), requested a license amendment to delete the current H. B. Robinson Steam Electric Plant, Unit 2, Surveillance Requirements (SRs) 3.1.7.1, 3.1.7.2, and 3.1.7.3 of Technical Specification 3.1.7, "Rod Position Indication," and renumber current SR 3.1.7.4 as SR 3.1.7.1.
The U. S. Nuclear Regulatory Commission staff has reviewed the licensee's submittal and determined that additional information is needed in order to complete our review. The enclosed document describes this request for additional information (RAI). The RAI was e-mailed to the licensee in draft form on June 23, 2014, with a response requested by July 25, 2014.
If you have any questions, please call me at 301-415-2760.
Docket No. 50-261

Request for Additional Information cc w/encl: Distribution via Listserv Sincerely,

REQUEST FOR ADDITIONAL INFORMATION H. B. ROBINSON STEAM ELECTRIC PLANT. UNIT 2 TECHNICAL SPECIFICATION 3.1.7 DELETION OF MONTHLY ROD POSITION INDICATION SURVEILLANCE REQUIREMENTS DOCKET NO. 50-261 By letter dated June 7, 2013 (Agencywide Documents Access and Management System Accession No. ML13182A019), Duke Energy Progress, Inc. (the licensee), requested a license amendment to delete the current H. B. Robinson Steam Electric Plant, Unit 2, Surveillance Requirements (SRs) 3.1.7.1, 3.1.7.2, and 3.1.7.3 of Technical Specification 3.1.7, "Rod Position Indication," and renumber current SR 3.1.7.4 as SR 3.1.7.1.
To complete its review, the U. S. Nuclear Regulatory Commission (NRC) staff requests the following additional information:
- 1. On page 3 of 13, Section 2.0, Detailed Description, the licensee stated, "The 92 day FREQUENCY takes into consideration other information available to the operator in the control room and SR 3.1.4.1, which is performed more frequently, adds to the determination of OPERABILITY of the rods. Deletion of SRs 3.1. 7.2 and 3.1. 7.3 will result in less frequent rod motion being required (every 92 days instead of 31 ), as well as less rod motion (1 0 steps instead of 19) being required during performance of the surveillance to confirm analog rod position indication system and bank demand position indication system capability to respond to rod motion. The deletion of these SRs will eliminate a monthly reactivity manipulation (reduction of reactor power to less than 98%)
to meet the 19 step rod motion requirement."
The licensee is requested to provide the frequency and the description of "the other information available to the operator in the control room." This information is needed by NRC staff to assess the acceptability of the change from 31 days to 92 days.
- 2. Title 10 of the Code of Federal Regulations, Section 50.36(c)(3), Surveillance Requirements, states surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met. State whether the proposed rod position indication accuracy is affected. If the proposed alternate rod position indication accuracy is affected, address the acceptability of the lower accuracy.
