SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION i
RELATED TO AMENDMENT NO 27 TO FACILITY OPERATING LICENSE NPF-52 i
j DOCKET N0. 50-414 I
i CATAWBA NUCLEAR STATION, UNIT 2 INTRODUCTION I
By letter dated June 19, 1987, Duke Power Company, et al., (the licensee) pro-posed that License Condition 2.C.(8)(a) of Facility Operating License NPF-52 be amended to allow an extension of time for the resolution of the accumulator 1
tank instrumentation issue. The extension would be for one complete cycle of j
operation.
A two operating cycle extension for Catawba Unit I was previously approved by amendment 15, issued on October 6, 1986, to Facility Operating License NPF-35.
The requested one cycle extension for Catawba Unit 2 would put both Units on approximately the same schedule for resolution of this issue and would allow the NRC staff additional time to complete its generic review.
i EVALUATION j
The proposed amendment would revise License Condition 2.C.(8)(a) of the Catawba Unit 2 license to allow an extension of time for the resolution of the accu-k mulator tank instrumentation issue which is related to Generic Letter 82-33,
" Supplement I to NUREG-0737, Requirements for Emergency Response Capability."
l It was also discussed in Section 7.5.2 of Supplement 5 to the Catawba Safety Evaluation Report (NUREG-0954) and is currently under staff review because of its generic implications.
The primary function of the accumulator pressure or level instrumentation is
)
to monitor the pre-accident status of the accumulators to assure that the j
passive safety system is in a ready state to serve its safety function. The licensee stated that the accumulator tank level and pressure are not referenced I
in any emergency procedure covering design basis events which may cause a harsh environment.
No operator actions in these procedures are based on i
l accumulator indications and the present instrumentation is fully qualified to l
perform its function of pre-accident monitoring.
Therefore, the staff con-cludes that extension of the date for upgrading the accumulator pressure or i
level instrumentation until startup following the second refueling outage is j
acceptable.
i 1
l Based on the above discussion, the modified License Condition 2.C.(8)(a) l would state that :
" Prior to startup following the second refueling outage, Duke Power i
Company shall provide qualified accumulator discharge instrumentation."

ENVIRONMENTAL CONSIDERATION The amendment involves a change in the use of facility components located within i
the restricted area 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 exposures.
The NRC staff has made a determination that the amendment involves no significant hazards consideration, and there has been no public comment on such finding.
Accordingly, the amendment meets the eligibility criteria for categorical ex-clusion 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.
CONCLUSION l
The Commission made a proposed determination that the amendment involves no i
significant hazards consideration which was published in the Federal Register (51 FR 28375) on July 29, 1987, and consulted with the state of South Carolina.
No public comments were received, and the state of South Carolina did not have any comments.
We have 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, and (2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of the amendmer,t will not be inimical to the connon defense and security or to the health and safety of the public.
