JAN 2 21986 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.11 TO FACILITY OPERATING LICENSE NO. NPF-30 UNION ELECTRIC COMPANY CALLAWAY PLANT UNIT 1 DOCKET NO. 50-483
1.0 INTRODUCTION
By letter dated August 13, 1985 as supplemented by letter dated November 15, 1985 Union Electric Company (the licensee) requested an amendment to Facility Operating License No. NPF-30 for operation of the Callaway Plant in Callaway County, Missouri.
The amendment approves a modification to Page 3/4 7-28 of the Callaway Technical Specifications.
2.0 DISCUSSION The fire suppression water supply system has three 50 percent capacity fire pumps. One pump is electric motor driven and two are diesel engine driven.
Two of the three fire pumps are required to be in service to deliver the required fire protection water demand.
Specification 4.7.10.1.2.c currently requires that each fire pump diesel engine be demonstrated operable at least once per 18 months, during shutdown, by subjecting the diesel engine to an inspection. By letter dated August 13, 1985, the licensee proposed to delete the requirement that this inspection be performed during shutdown.
I By letter dated November 15, 1985, the licensee informed us that the subject inspection will be performed either during shutdown or during power operation when the other two fire pumps are operable.
By the November 15, 1985 letter, the licensee proposed wording for Specification 4.7.10.1.2.c to clarify this point.
3.0 EVALUATION The required fire protection water demand is available whenever any two of i
the three station fire pumps are operable. The proposed change to Specifi-cation 4.7.10.1.2.c will allow the 18-month inspection of a fire pump diesel engine during power operation only if the other diesel engine driven fire pump and the electric motor driven fire pump are both operable.
Therefore, if one of the two diesel engine driven pumps is taken out of service during power operation for inspection, the two remaining fire pumps will be operable, and the required fire protection water demand will be available.

. Consequently, there is reasonable assurance that conducting the 18-month fire pump diesel engine inspection during power operation will not adversely affect the fire protection water supply. Based on our eval-uation, we find that the licensee's proposed change to Specification 4.7.10.1.2.c, as shown in their letter dated November 15, 1985, is acceptable.
4.0 ENVIRONMENTAL CONSIDERATION
This amendment involves a change in the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no significant change in the types or significant increase in the amounts 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 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 Section 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environ-mental assessment need be prepared in connection with the issuance of this amendment.
5.0 CONCLUSION
The Comission made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal Register (50 FR 38923) on September 25, 1985, and consulted with the state of Missouri.
No public comments were received, and the state of Missouri did not have any comments.
I 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 Comission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
