SAFETY EVALUATION BY THE OFFICE OF NUCLEAR' REACTOR REGULATION SUPPORTING AMENOMENT NO. 131 TO FACILITY OPERATING' LICENSE NO. DPR-72 FLORIDA POWER CORPORATION, ET AL.
CRYSTAL' RIVER UNIT-NO. 3 NUCLEAR GENERATING PLANT DOCKET NO. 50-302 BACKGROUND-By letter dated May 10, 1990, Florida. Power Corporation (FPC or the licensee) requested an amendment to the Technical Specifications (TS) appended to Facility Operating License No. OPR-72 for the-Crystal River _ Unit No. 3 Nuclear Generating Plant (CR-3).
The proposed amendment would update the~16-month emergency diesel generator load testing requirements to reflect the increased' generator capability.
It would also remove the surveillance requirements on block load timers in modes 5 and 6 and delete two notes that are no longer applicable.
EVALUATION The diesel generator load test is performed-.to ensure that the' diesel generators-always'have the capability to supply the worst-case accident. loads.
The capa--
bilities of the diesel generators and the size of the worst-case accident loads have changed as a result of recent modifications.
The requested changes update
-i the TS surveillance requirements to reflect-the upgraded configuration of the plant.
Currently, the TS require a 60-minute' test to be run-at'a'1 cad of at least 2750
~
kw, but less than 3000 kw, with the first 5 minutes of the test to be run at a load of at least 3248 kw, the previous predicted worst-case automatically connected load.
The ;roposed amendment wouldLrequire that this test be-performed with a minemum load of 3100 kw and aimaximum load of 3250 kw.
The minimum load of 3100 kw provides margin above-the_ presently predicted worst-case automatically connected accident load, and the maximum load of'3250 kw is the upper limit of the diesel's 200-hour rating.
Since the proposed testing range is adequate to ensure a proper minimum load while also providing-assurance that the diesel will not be overloaded, the proposed change is-acceptable.
The proposed changes would also modify the.TS covering automatically connected loads.
Currently, the TS require thatLautomatically connected. loads be verified to be less than 3248 kw.
The proposed changes would' reduce the allowable load to 3100-kw.
This value exceeds the predicted worst-case automatically connected accident load and is the maximum value for which the diesels are qualified 1
by the 18-month test, and is therefore acceptable.

5 In addition, the proposed amendment would remove'the testing requirements for automatic load sequence _ timers in modes 5 and 6.
Since;the accidents for which j
- the timers are needed cannot occur. in these modes, this-change -is' acceptable.
^
Finally, two notes would be deleted from the TS which are'not applicable ~after the end of cycle 7.
These notes are being deleted because they are no longer applicable and unnecessarily complicate the specification.~ _Therefore,:the staff finds'this change. acceptable.
SUMMARY
Based on'our review, the changes proposed in this request are adequate and
~
acceptable.
ENVIRONMENTAL CONSIDERATION j
This amendment involves a change to a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
We.have determined:that the amendment ir<olves 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 this' amendment involves no significant hazards consideration and there=has been no public comment on such finding.
Accordingly, this amtndment 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.
CONCLUSION 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'sl regulations and:the issuance of t
this amendment will not be inimical to the common defense and security or to the' health and safety of the public.
