Facility Operating License No. NPF-58 for the Perry Nuclear Power Plant, Unit No. 1.
The proposed amendment would revise the interval for conducting the diesel generator inspection required by Technical Specification (TS)
-4.8.1.1.2.e.1 from every 18 months to every refueling outage.
It would also revise the reference to the NRC staff Safety Evaluation Report (SER) contained in Section 1 of Attachment 2 to NPF-58 from November 5, 1985, to July 8, 1986,

2.0 EVALUATION s
On July 8, 1986, the NRC staff transmitted its generic SER on the operability / reliability of Transamerica Delaval, Inc. (TOI) emergency diesel generators (EDGs) for the Perry Nuclear Power Plant, Units 1 and 2, to the licensees.
This SER was developed based upon Technical Evaluation Reports (TERs) from our contractor, Pacific Northwest Laboratory (PNL).
The staff concluded that the implementation of the TDI Owners Group and PNL recommendations concerning quality revalidation inspections, component modifications and replacement, load restrictions, operating precautions, etc. will establish the adequacy of the TOI diesel generators for nuclear service as required by General Design Criterion (GDC) 17.
The staff further concluded that these programs (actions) would ensure that the design and manufacturing quality of the TOI diesel engines is within the range normally assumed for diesel engines designed and manufactured in accordance with 10 CFR 50, Appendix B.
Continued reliability / operability of the TOI diesel i
engines for the 40 year life of the Perry Nuclear Power Plant, utilizing I
those engines, would be assured by implementation of the maintenance / surveil-lance program discussed in Section 2.3 of the SER.

assurance,'and operational surveillance and maintenance, are adequate.
-(3) Expanded engine tests and inspections as needed to support Phases I and II.
These programs'are supplemental to the requirements which must normally be satisfied (e.g. Regulatory Guide 1.108).
The staff also concluded that several of_the Phase I program diesel engine components merited special emphasis in the area of load restrictions and/or 4

3.0 ENVIRONMENTAL CONSIDERATION
This amendment involves a change to a surveillance requirement.
We have 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. Tho Commission has previously issued a proposed finding that this amendment involves no significant hazards con-sideration and there has been no public comment on such finding.
Accordingly, this amendment meets the eligibility criteria for categorical exclusion set Pursuant to 10 CFR 51.22(b), no environmental forth in 10 CFR 51.22(c)(9).
impact statement or environmental asstssment need be prepared in connection with the issuance of this amendment.
4.0 CONCLUSION
We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the pubife 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 this amendment will not be inimical to the common defense and security or to the health and safety of the public.
