REQUEST FOR ADDITIONAL INFORMATION REGARDING ADOPTION OF TECHNICAL SPECIFICATION TASK FORCE TRAVELER 523, REVISION 2. LICENSE AMENDMENT REQUEST CALVERT CLIFFS NUCLEAR POWER PLANT. UNIT NOS. 1 AND 2 NINE MILE POINT NUCLEAR STATION, UNIT NO. 2 R. E. GINNA NUCLEAR POWER PLANT CALVERT CLIFFS NUCLEAR POWER PLANT. LLC NINE MILE POINT NUCLEAR STATION. LLC R. E. GINNA NUCLEAR POWER PLANT, LLC EXELON GENERATION COMPANY. LLC DOCKET NOS. 50-317, 50-318. 50-410, AND 50-244 By letter dated July 10, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14191A255), Exelon Generation Company, LLC (the licensee),
submitted a license amendment request that proposed changes to the technical specifications for Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 and 2; Nine Mile Point Nuclear Station, Unit No. 2; and R. E. Ginna Nuclear Power Plant. According to the licensee, the proposed amendment is consistent with Technical Specification Task Force (TSTF) Traveler 523 (TSTF-523), Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation," dated February 21, 2013 (ADAMS Accession No. ML13053A075).
TECHNICAL SPECIFICATIONS BRANCH REQUEST FOR ADDITIONAL INFORMATION 1 During the application review, the U.S. Nuclear Regulatory Commission (NRC) staff identified the following issue:
In Attachment 1 of the submittal, the licensee stated that the proposed amendment was consistent with TSTF-523, Revision 2. TSTF-523, Revision 2 has been approved for plant-specific adoption by the NRC.
In Attachment 2c of the submittal, the new Surveillance Requirement (SR) for Limiting Condition for Operation (LCO) 3.4.8 (i.e., SR 3.4.8.3) uses the wording, "Verify required RHR [residual heat removal] loop locations," versus the approved TSTF wording, "Verify RHR loop locations.... " When an LCO requires two trains of the RHR to be OPERABLE, TSTF-523 does not use the qualifier "required" in the SR language; therefore, the SR 3.4.8.3 wording is inconsistent with TSTF-523. The word "required" is redundant since LCO 3.4.8 requires both trains of RHR to be OPERABLE, and in every other instance throughout the submittal when two trains of RHR are required to be OPERABLE, the word "required" is not used in the associated SR.
Please provide a submittal that uses language consistent with the approved traveler or provide a technical justification for the deviation.
