g SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.168 TO FACILITY OPERATING LICENSE NO. DPR-20 CONSUMERS POWER COMPANY PALISADES PLANT DOCKET NO. 50-25' l.0 INTRODUCTION By letter dated December 13, 1994, as supplemented May 3, 1995, the Consumers Power Company (the licensee) requested an amendment to the Technical Specifications (TS) appended to Facility Operating License No. DPR-20 for the Palisades - Plant. The proposed amendment revises the TS to add a high thermal performance (HTP) departure from nucleate boiling (DNB) correlation to Safety Limit 2.1.
The HTP correlation is used for HTP fuel loaded during recent fuel cycles. The May 3,1995, submittal provided clarifying information which was within the scope of the initial application and did not affect the staff's initial proposed no significant hazards considerations findings.
2.0 E)ALUATION The. proposed changes involve the addition of'a third DNB correlation. The affected specifications are:
(1) TS 2.1 Safety Limit - Reactor Core The "HTP" DNB correlation is added under the correlation column and its appropriate minimum DNB limit of "1.141" is added under the Safety Limit.
The HTP correlation is an extension of the ANFP correlation. The HTP-correlation reflects the results of additional DNB testing of HTP fuel.
The HTP DNB correlation and its associated Safety Limit of maintaining a minimum DNBR [DNB ratio] of 1.141 are documented in the NRC-approved Siemens topical report, EMF-92-153(P)(A) (December 28,1993). Therefore, the addition of the HTP correlation and Safety Limit of 1.141 is acceptable.
(2) Basis 2.1 Reactor Core Safety Limit The change to the basis is to clarify the proper use of the HTP correlation in relation to the ANFP correlation and to add the approved methodology, which is Topical Report EMF-92-153(P)(A) and Supplement 1, "HTP: Departure from Nucleate Boiling Correlation for High Thermal Performance Fuel," March 1994.
We have reviewed the request by Consumers Power Company to revise the Palisades Nuclear Plant TS to add a third DNB correlation (HTP), its Safety Limit of 1.141, its Basis, and an approved topical report to support the 9506230261 950613 PDR ADOCK 05000255 P

proposed changes since an approved methodology is used.
Based on our review, we conclude that the proposed changes are acceptable since an approved methodology is used.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Michigan State official-was notified of the proposed, issuance of,the amendment. The Michigan State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
'the amendment changes a requirement.with respect to 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 significant1 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 the amendment-involves no significant hazards consideration and there has been'no public comment on such finding (60 FR 24910). Accordingly, the amendment meets the-eligibility criteria for categorical, exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant.to 10 CFR 51.22(b),ino environmental impact statement s
or environmental assessment need be prepared in connection with. the issuance e
of the amendment.-
5.0 CONCLUSION
The staff has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the hea'lth and safety of the public will not be endangered by operation in the proposed manner, (2) such j
activities will be conducted in' compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
