SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 168 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-12 SOUTH CAROLINA ELECTRIC & GAS COMPANY SOUTH CAROLINA PUBLIC SERVICE AUTHORITY VIRGIL C. SUMMER NUCLEAR STATION, UNIT NO. 1 DOCKET NO. 50-395
1.0 INTRODUCTION
By application dated September 19, 2003, South Carolina Electric & Gas Company (the licensee) requested changes to the Technical Specifications (TSs) for the Virgil C. Summer Nuclear Station (VCSNS). The proposed changes would revise Surveillance Requirement (SR) 4.2.4.2 to specifically identify the Power Distribution Monitoring System (PDMS) being used in determining the Quadrant Power Tilt Ratio (QPTR) with one inoperable Power Range Channel.
2.0 REGULATORY EVALUATION
It is stated in Title 10, Code of Federal Regulations (10 CFR) Section 50.36(c)(3) that SRs be performed in order to assure the necessary quality of systems and components be maintained, the facility operation will be within safety limits, and that the limiting condition for operation will be met.
3.0 TECHNICAL EVALUATION
By letter dated April 9, 1999, the staff approved Amendment No. 142 to use PDMS for performing surveillance of the QPTR above 25 percent rated thermal power (RTP). TS 3.3.3.11 was added to the VCSNS TSs identifying the PDMS uses and operability. TS 3.3.3.11 states that the PDMS shall be operable at power ranges above 25 percent RTP to meet the SR.
TS 3.3.3.11 also indicates the usage of the movable incore detector system to monitor QPTR if the PDMS is declared inoperable.
The changes to SR 4.2.4.2 were not previously made as part of Amendment No. 142. The licensee is requesting approval of this amendment to clarify the use of the PDMS as a means of measuring the QPTR to satisfy the surveillance requirement. The proposed SR 4.2.4.2 will state that the QPTR shall be determined to be within the established limit when above 75 percent RTP, with one Power Range Channel inoperable, by using the PDMS or movable incore detectors to confirm that the normalized symmetric power distribution obtained from two sets of four symmetric thimble locations is consistent with the indicated QPTR at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Operation of the PDMS does not depend upon the operability of the Power Range Channels and, therefore, usage of PDMS in performing the SR with one inoperable Power Range Channel is acceptable. The proposed change to SR 4.2.4.2 does not incur any adverse levels of safety and is administrative in the clarification of the use of the PDMS with one Power Range Channel inoperable. Therefore, the staff finds the change to SR 4.2.4.2 to be acceptable.
4.0 STATE CONSULTATION
In accordance with the Commissions regulations, the State of South Carolina official was notified of the proposed issuance of the amendment. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes SRs.
The Nuclear Regulatory Commission staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (69FR16623). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
6.0 CONCLUSION
Based on its review of technical justification provided by the license, the staff concluded that the proposed TS change is in accordance with the current licensing basis and is therefore acceptable. Revision to SR 4.2.4.2 will clarify the use of the PDMS in performing surveillance of the QPTR above 75 percent RTP with one inoperable Power Range Channel. No change to the safety analysis was required due to this amendment reflecting only an administrative change to the VCSNS TS.
The Commission has concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
