UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 FE V

K By letter dated March 17, 1997, as supplemented by letter dated April 13, 1998, the Carolina Power 8 Light Company (CP8L or the licensee) submitted a request for changes to the Shearon Harris Nuclear Power Plant, Unit 1 (SHNPP), Technical Specifications (TS). The requested changes would revise TS surveillances 4.1.2.2.c, 4.5.2.e, 4.6.2.1.c, 4.6.2.2.c, 4.6.3.2, 4.7.1.2.1.b, 4.7.3.b, and 4.7.4.b to delete specific provisions in the text of the.
surveillances that the tests must be done while the unit is shut down. The current wording for these TS surveillances requires that all testing associated with the surveillance be performed
'uring shutdown.
Given such constraints, SHNPP should not take credit for equivalent tests on some components that are currently performed at power to comply with other surveillances.
The proposed amendment would eliminate the shutdown requirement and allow SHNPP the flexibilityto take credit-for equivalent tests on some components that are currently being performed at power in accordance with the TS.
2.D ~T The existing TS surveillances 4.1.2.2.c, 4.5.2.e, 4.6.2.1.c, 4.6.2.2.c, 4.6.3.2, 4.7.1.2.1.b, 4.7.3.b, and 4.7.4.b all require a specified testing frequency of 18 months and an additional modiTier that the testing be done while the unit is shut down. These surveillances involve the Reactivity Control system, the Emergency Core Cooling system, Containment Spray, Containment Isolation valves, AuxiliaryFeedwater system, Component Cooling Water system, and the Emergency Service Water system.
The licensee states that complying with the requirement to perform these surveillances at shutdown often leads to unnecessary test repetition during refueling outages.
Deleting the requirement to perform these surveillances at shutdown would allow SHNPP to take credit for equivalent tests which are currently being performed at power to satisfy other TS surveillances.
The proposed change does not specifically authorize the performance of any tests at power; however, it does allow SHNPP to evaluate ifthe plant conditions willallow safe testing of the components and perform the tests in accordance with those evaluations.

The Standard Technical Specifications (STS) for Westinghouse Plants, NUREG-1431, Revision 1, have surveillance requirements equivalent to seven of the eight TS surveillances subject to this amendment, and ail of the STS surveillances have 18-month unrestricted frequencies.
The STS Bases state that the 18-month frequency is based on the need for the surveillance to be performed under conditions that apply during a unit outage and the potential for unplanned plant transients ifthe surveillance were performed with the reactor at power.
However, the Bases do not preclude taking credit for testing already performed for specific components, or from evaluating the specific plant conditions required for each test. The remaining TS surveillance, 4:1:2:2.c, is not included in the STS. 'he STS'allows this surveillance to be relocated to a licensee controlled document.
By relocating this surveillance to a controlled document, the licensee is permitted to change the surveillance pursuant to the requirements of 10 CFR 50.59. Therefore, removing the shutdown condition from the requested TS survelliances willnot have a detrimental effect on the surveillance program.
In addition, the staff concluded in Generic Letter 91-04, "Changes in Technical Specification Surveillance Intervals To Accommodate A 24-Month Fuel Cycle," that the TS do not need to restrict surveillances to only being performed during shutdown.
However, when refueling interval surveillances are performed during power operation, licensees should give proper regard for their effect on the safe operation of the plant. Ifthe required surveillance tests during plant operation would adversely affect safety, the licensee should postpone the surveillance until the unit is shut down for refueling or is in a condition or mode that is consistent with the safe conduct of that surveillance.
SHNPP willcontinue to determine the necessary plant conditions to safely perform the required surveillance tests on the affected components.
Based on the above evaluation, the staff finds that the proposed TS change for the requested TS surveillances is acceptable.

TI In accordance with the Commission's regulations, the State of North Carolina officialwas notified of the proposed issuance of the amendment.
The State official had no comments.

TO 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 the Surveillance Requirements.
The NRC 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 (62 FR 19826). Accordingly, the amendment meets the eligibilitycriteria 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.
The Commission has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public willnot be endangered by operation in the proposed manner, (2) such activities willbe conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment willnot be inimical to the common defense and security or'to the health and safety of the public.
