April 22, 2021 Mr. Ken J. Peters Senior Vice President and Chief Nuclear Officer Attention: Regulatory Affairs Vistra Operations Company LLC Comanche Peak Nuclear Power Plant 6322 N FM 56 P.O. Box 1002 Glen Rose, TX 76043
SUBJECT:
COMANCHE PEAK NUCLEAR POWER PLANT, UNIT NOS. 1 AND 2 -
CORRECTION TO AMENDMENT NOS. 168 AND 168 RE: ADOPTION OF TECHNICAL SPECIFICATIONS TASK FORCE TRAVELER TSTF-545, REVISION 3, TS INSERVICE TESTING PROGRAM REMOVAL & CLARIFY SR USAGE RULE APPLICATION TO SECTION 5.5 TESTING (CAC NOS. MF7684 AND MF7685)
Dear Mr. Peters:
By letter dated April 13, 2017 (Agencywide Documents Access System (ADAMS) Accession No. ML17074A494), the U.S. Nuclear Regulatory Commission (NRC, the Commission) issued Amendment No. 168 to Facility Operating License No. NPF-87 and Amendment No. 168 to Facility Operating License No. NPF-89 for Comanche Peak Nuclear Power Plant, Unit Nos. 1 and 2 (Comanche Peak, Units 1 and 2), respectively. The amendments consisted of changes to the technical specifications (TSs) based on NRC-approved Technical Specifications Task Force (TSTF) Standard Technical Specifications Change Traveler TSTF-545, Revision 3, TS Inservice Testing Program Removal & Clarify SR [Surveillance Requirements] Usage Rule Application to Section 5.5 Testing.
The NRC staff identified an error on TS page 1.1-3 associated with these amendments.
Specifically, in the new definition of INSERVICE TESTING PROGRAM, the word license was included instead of licensee.
The changes in TSTF-545, Revision 3, include adding a definition of INSERVICE TESTING PROGRAM to Section 1.0 of the TSs. This definition includes the words licensee program.
Neither the license amendment request, dated April 27, 2016 (ADAMS Accession No. ML16120A432), nor the supplement, dated June 30, 2016 (ADAMS Accession No. ML16196A238), identified a variation from the definition. In Sections 2.2 and 3.2 of the NRC staffs safety evaluation dated April 13, 2017, the NRC staff discusses the licensees request to add the definition of INSERVICE TESTING PROGRAM from TSTF-545, to the Comanche Peak TSs and specifically repeats the TSTF-545 definition.
The NRC staff determined that the errors were inadvertently introduced during the preparation of the license amendment and are entirely typographical in nature. The corrections do not
change any of the conclusions in the safety evaluation associated with the amendment and do not affect the associated notice to the public.
The enclosure to this letter contains the correct TS page 1.1-3. Please replace the corresponding page issued by Amendment Nos. 168 and 168 for Comanche Peak, Units 1 and 2, respectively.
We regret any inconvenience this may have caused. If you have any questions, please contact me at 301-415-6256 or Dennis.Galvin@nrc.gov.
Sincerely,
/RA/

ENCLOSURE CORRECTION TO TECHNICAL SPECIFICATION PAGE 1.1-3 TO AMENDMENT NOS. 168 AND 168 VISTRA OPERATIONS COMPANY LLC COMANCHE PEAK NUCLEAR POWER PLANT, UNIT NOS. 1 AND 2 DOCKET NOS. 50-445 AND 50-446
1.1 Definitions (continued)
DOSE EQUIVALENT XE-133 ENGINEERED SAFETY FEATURE(ESF)RESPONSE TIME INSERVICE TESTING PROGRAM Definitions 1.1 DOSE EQUIVALENT XE-133 shall be that concentration of Xe-133 (microcuries per gram) that alone would produce the same acute dose to the whole body as the combined activities of noble gas nuclides Kr-85m, Kr-87, Kr-88, Xe-133m, Xe-133, Xe-135m, Xe-135, and Xe-138 actually present. If a specific noble gas nuclide is not detected, it should be assumed to be present at the minimum detectable activity. The determination of DOSE EQUIVALENT XE-133 shall be performed using effective dose conversion factors for air submersion listed in Table 111.1 of EPA Federal Guidance Report No. 12, 1993, "External Exposure to Radionuclides in Air, Water, and Soil", or using the dose conversion factors from Table 8-1 of Regulatory Guide 1.109, Revision 1, NRC, 1977.
The ESF RESPONSE TIME shall be that time interval from when the monitored parameter exceeds its ESF actuation setpoint at the channel sensor until the ESF equipment is capable of performing its safety function (i.e., the valves travel to their required positions, pump discharge pressures reach their required values, etc.). Times shall include diesel generator starting and sequence loading delays, where applicable. The response time may be measured by means of any series of sequential, overlapping, or total steps so that the entire response time is measured. In lieu of measurement, response time may be verified for selected components provided that the components and methodology for verification have been previously reviewed and approved by the NRG.
The INSERVICE TESTING PROGRAM is the licensee program that fulfills the requirements of 10 CFR 50.55a(f).
