UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCI EAR REACTOR REGULATION SUPPORTING AMENDMENT NO.
TO FACILITY OPERATING LICENSE NO.
NPF-63 CAROLINA POWER 8
LIGHT COMPANY et al.
SHEARON HARRIS NUCLEAR POWER PLANT UNIT 1 DOCKET NO. 50"400
1.0 INTRODUCTION
2.0 By letters dated October 26,
- 1989, as supplemented December 15, 1989, the Carolina Power 5 Light Company submitted a request for changes to the Shearon Harris Nuclear Power Plant, Unit 1, Technical Specifications (TS)
Table 3.3-3, Engineered Safety Features Actuation System Instrumentation.
This change clarifies the requirements of Item 6.a and Action Statement 23 of TS Table 3.3-3.
The December 15, 1989, letter provided clarifying information that did not change the proposed determination of no significant hazards consideration as published in the Federal
~Re ister (55 FR 18410) dated May 2, 1990.
Currently, the required number of channels for manual initiation of auxiliary feedwater in TS Table 3.3-3 is listed as one per pump.
This is correct for the motor driven auxiliary feedwater pumps.
However, the turbine driven auxiliary pump has two control channels per pump, one of which is required to manually start the pump.
EVALUATION Currently, Item 6.a in TS Table 3.3-3 is correct as written.
- However, Item 6.a, as currently written, could be misleading because it is written with minimal information which, in turn, does not clearly reflect the as-built plant.
The auxiliary feedwater system has both motor driven pumps and a turbine driven pump.
Both type of pumps require only one control channel for manual initiation.
The information which is absent from the as-written requirement, however, is that the motor driven pumps have only a single control channel while the turbine driven pump has two control channels.
The proposed amendment would incorporates separate line items for the motor driven pumps and for the turbine driven pump, the number of control channels for each pump type and the number of control channels each requires for manual initiation.
The amendment would more clearly reflect the design and as-built plant and would simplify or clarify determinations of'perability related to TS Table 3.3-3 and is, therefore, acceptable.
Further, Action Statement 23 is changed to be consistent with the change in Item 6.a and is also acceptable.

- 3. 0 ENVIRONMENTAL CONSIDERATION This amendment changes a requirement with respect to installation or use of a facility component located within the restricted areas as defined in 10 CFR Part 20.
The 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' proposed finding that this amendment involves no significant hazards consideration, and there has been no public comment on such finding.
Accordingly, this 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 this amendment.
- 4. 0 CONCLUSION The Commission made a proposed determination that this amendment involves no significant hazards consideration which was published in the Federal
~Re ister (55 FR 18410) on May 2, 1990, and consulted with the State of North Carolina.
No public comments or requests for hearing were received, and the State of North Carolina did not have any comments.
The staff 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 Commission's regulations, and (3) the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
