SUBJECT:

SURRY POWER STATION, UNIT NOS. 1 AND 2 - CORRECTION TO ISSUANCE OF AMENDMENT NOS. 315 AND 315, REGARDING REVISED EMERGENCY PLAN FOR RELOCATION OF THE TECHNICAL SUPPORT CENTER (EPID L-2022-LLA-0167)

Dear Eric Carr:

On November 7, 2023 (Agencywide Document s Access and Management System (ADAMS)

Accession No. ML23242A229), the U.S. Nuclear Regulatory Commission (NRC, the Commission) issued Amendment No. 315 to S ubsequent Renewed Facility Operating License No. DPR-32 and Amendment No. 315 to Subsequent Renewed Facility Operating License No. DPR-37 for the Surry Power Station, Unit Nos. 1 and 2, respectively. The amendments revised the license and Emergency Plan in response to your application dated November 18, 2022 (ML22322A182), as supplemented by letters dated May 31 (ML23167B007) and August 7, 2023 (ML23220A148). This amendment approved the relocation of the Technical Support Center (TSC) from its current location adjacent to the Main Control Room to a building outside the protected area that was used previously as the Local Emergency Operations Facility.

Subsequently, your staff by letter dated January 3, 2024 (ML24003A902) identified a discrepancy in the license amendment reques ts submittal, ML23167B007, Table 4-1, Summary of TSC Dose Results, which typographically presented an error in the Refueling Water Storage Tank leakage dose rate of 0.2100 rather than the correct value for that parameter of 0.0210 rem TEDE. That corrected value is now utilized on the associated page of the issued amendment and enclosed.

Therefore, consistent with NRC staff guidance dated January 16, 1997 (ML103260096), based on the NRCs policy established by SECY-96-238 and the corresponding SRM, these errors can be corrected by a letter to the licensee from the NRC staff.

E. Carr

Enclosed please find the corrected page 20 of Amendments Nos. 315 and 315 for Surry, Units 1 and 2, respectively. The corrections do not change any of the conclusions in the safety evaluations or no significant hazards consideration determination as previously noticed in the Federal Register.

Sincerely,

/RA/

3.6.2.5 TSC Dose Consequence Analysis Conclusion

The results of the licensees calculation indicate that the TSC personnel will be protected from radiological hazards, including direct radiation and airborne radioactivity from in plant sources under accident conditions, to the same degree as MCR personnel (radiation exposures shall not exceed 5 rem TEDE for the duration of the postulated accident). Also requirements contained in Clarification of TMI Action Plan Require ments NUREG-0737 (ML051400209) were considered in this SE.

The staff used RADTRAD version 5.0.3 and MicroShield version 13 to perform independent confirmatory calculations. These confirmatory calculations utilizing the LOCA analysis initial conditions, inputs and assumptions provided in the LAR and CLB documents and obtained results similar to those provided in the application and within acceptance criteria.
