DRAFT REQUEST FOR ADDITIONAL INFORMATION (RAI)
VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS I AND 2 DOCKET NUMBER 50-280 AND 50-281 PROPOSED LICENSE AMENDMENT REQUEST REGARDING EXTENSION OF TYPE A AND C TEST INTERVALS (TAC NOS. MF2612/2613)
By letter dated August 12, 2013 (Agencywide Documents Access and Management Systems (ADAMS)
Accession No. ML13232A042), as supplemented by letter dated January 24, 2014 (ADAMS Accession No. ML14035A219), Virginia Electric and Power Company, the licensee of Surry Power Station (Surry) Units 1 and 2, submitted License Amendment Request (LAR) pursuant to the requirements of Title 10 of the Code of Federal Regulations Part 50.90. The licensee requests Nuclear Regulatory Commission (NRC) review and approval of a revision to the Surry containment leakage rate testing program in accordance with Option B of 10 CFR 50, Appendix J. The purpose of this request is to adopt Revision 3-A of NEI 94-01, which describes an approach for implementing the optional performance-based requirements of Option B, including provisions for extending primary containment integrated leak rate test (ILRT) intervals to 15 years and Type C test intervals to 75 months, and incorporates the regulatory positions stated in RG 1.163.
The staff requests the following request for additional information (RAI) to complete its review:
- 1. What is the peak containment pressure (Pa) for Type A testing performed in Surry Units 1 & 2?
- 2. Discuss the procedure used for the development of bases for new Type C testing frequencies. Discuss all the important performance factors identified, that are considered in establishing testing intervals (e.g.
past performance, service design, safety impact, cause determination.)
- 3. Describe the post-outage scope report issued to document the local leak rate test periodically and to ensure that all pre-maintenance and post-maintenance testing is complete. Discuss how the post-outage scope report provides a written record of the extended testing interval changes and the reasons for the changes based on testing results and maintenance history.
Please provide your RAI response by March 28, 2014. If you have any questions, you may contact me at (301) 415-2760.
Respectfully, Martha Barillas Project Manager-Surry Units 1 & 2 NRR/DORL/Licensing Branch II-1 US Nuclear Regulatory Commission 301-415-2760
