May 22, 2023 Mr. Daniel G. Stoddard Senior Vice President and Chief Nuclear Officer Innsbrook Technical Center 5000 Dominion Boulevard Glen Allen, VA 23060-6711
SUBJECT:
VIRGIL C. SUMMER NUCLEAR STATION, UNIT 1 - CORRECTION TO ISSUANCE OF AMENDMENT NO. 222 TO RELOCATE SELECTED SURVEILLANCE FREQUENCIES TO A RISK-INFORMED LICENSEE CONTROLLED PROGRAM (EPID L-2021-LLA-0064)
Dear Mr. Stoddard:
On August 16, 2022 (Agencywide Documents Access and Management System (ADAMS)
Accession No. ML22160A365), the U.S. Nuclear Regulatory Commission (NRC) issued Amendment No. 222 to Renewed Facility Operating License No. NPF-12 for the Virgil C.
Summer Nuclear Station, Unit 1. The amendment revised the Technical Specifications (TSs) by relocating selected TS Surveillance Frequencies to a licensee-controlled program. This change was consistent with Technical Specification Task Force (TSTF) traveler TSTF-425, Revision 3 (ADAMS Accession No. ML090850642).
Subsequently, by letter dated April 25, 2023 (ADAMS Accession No. ML23115A400), Dominion Energy identified that the camera-ready page provided with the amendment request had an unintentional change to Technical Specification (TS) Surveillance Requirement (SR) 4.8.1.1.2.a.3. The NRC staff confirmed that the marked-up pages provided with the amendment did not include a proposed change to TS SR 4.8.1.1.2a.3 and that the camera-ready version contained an administrative error. Therefore, consistent with NRC staff guidance dated January 16, 1997 (ML103260096), based on the NRCs policy established by SECY-96-238, this error can be corrected by a letter to the licensee from the NRC staff.
Accordingly, the corrected page 3/4 8-3 is enclosed with this letter. The corrections do not change any of the conclusions associated with the issuance of Amendment No. 222 to Renewed Facility Operating License No. NPF-12, and do not affect the no significant hazards consideration published in the Federal Register on June 15, 2022 (86 FR 31741).
D. Stoddard If you have any questions, please contact me at 301-415-4032, or via email at Ed.Miller@nrc.gov.
Sincerely,
/RA/

SUMMER - UNIT 1 3/4 8-3 Amendment No. 77, 93, 98, 121, 139, 164, 222 ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) 4.8.1.1.2 Each EDG shall be demonstrated OPERABLE:
- a.
In accordance with the Surveillance Frequency Control Program by:
- 1.
Verifying the fuel level in the day tank and fuel storage tank.
- 2.
Verifying the fuel transfer pump can be started and transfers fuel from the storage system to the day tank.
- 3.
Verifying the diesel generator can start* and accelerate to synchronous speed (504 rpm) with generator voltage and frequency at 7200 +/- 720 volts and 60 +/- 1.2 Hz.
- 4.
Verifying the generator is synchronized, gradually loaded* to an indicated 4150-4250 kW** and operates for at least 60 minutes.
- b.
In accordance with the Surveillance Frequency Control Program and after each operation of the diesel where the period of operation was greater than or equal to 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> by removing accumulated water from the day tank.
- c.
In accordance with the Surveillance Frequency Control Program by checking for and removing accumulated water from the fuel oil storage tanks.
- d.
By sampling new fuel oil based on the applicable ASTM standard prior to addition to storage tanks and:
- 1.
By verifying based on the tests specified in the applicable ASTM standard prior to addition to the storage tanks that the sample has:
a)
An API Gravity of within 0.3 degrees at 60°F or a specific gravity of within 0.0016 at 60/60°F, when compared to the supplier's certificate, or an absolute specific gravity at 60/60°F of greater than or equal to 0.83 but less than or equal to 0.89, or an API gravity of greater than or equal to 27 degrees but less than or equal to 39 degrees; b)
A kinematic viscosity at 40°C of greater than or equal to 1.9 centistokes, but less than or equal to 4.1 centistokes (alternatively, Saybolt viscosity, SUS at 100°F of greater than or equal to 32.6, but less than or equal to 40.1), if gravity was not determined by comparison with the supplier's certification;
- This test shall be conducted in accordance with the manufacturer's recommendations regarding engine prelube and warmup procedures, and as applicable regarding loading recommendations.
- This band is meant as guidance to avoid routine overloading of the engine. Loads in excess of this band shall not invalidate the test.
