.O SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENOMENT NO.168 TO FACILITY OPERATING LICENSE NO. DPR-62 l
CAROLINA POWER & LIGHT COMPANY-BRUNSWICK STEAM ELECTRIC PLANT, UNIT 2 DOCKET NO. 50-324
1.0 INTRODUCTION
By letter dated June 9,1989 from A.B. Cutter (CP&L) to NRC, the licensee submitted a request for the Technical Specification changes for Brunswick Steam Electric Plant (Brunswick), Unit 2, for Cycle 9.
The Cycle 9 reload core will consist of three types of GE fuel BP8x8R, GE8x8EB, and GE8x8NB, of which the type GE8x8NB is a new fuel type. The GE8x8NB fuel was approved for reload in Amendment 18 to GESTAR-II (NEDE-24011-P-A). Due to the use of new fuel GE8x8NB, the licensee recalculates the minimum critical power ratio (MCPR) safety limit and proposes a change in the Technical Specifications. We evaluate the changes in the following.
2.0 EVALUATION CF TECHNICAL SPECIFICATION CHANGES (1) Section 2.1.2 THERMAL POWER The MCPR safety limit for Cycle 9 with the new GE8x8NB fuel type is changed from 1.04 to 1.06.
The new MCPR limit is based on an approved methodology cescribed in the approved Amendment 18 to NEDE-24011-P-A. The degree of conservatism associated with the new MCPR limit is the same as that of the old MCPR limit, i.e., there is an adequate margin to assure that more than 99.9 percent of the fuel rods in the core will not experience boiling transition during normal operation and anticipated operational occurrences (A00s).
Based on the approved methodology and adequate conservatism, we concluce that the new MCPR limit of 1.06 is acceptable for use in Cycle 9.
(2) 5.3.1 FUEL ASSEMBLIES The fuel types in the Cycle 9 reload core are BP8x8R, GE8x8EB, and GE8x8NB.
The fuel types BP8x8R and GE6x8EB are currently in Cycle 8 core.
The new fuel type GE8x8NB was approved in Amendment 18 to NEDE-24011-P-A.
We thus conclude that the three fuel types BP8x8R, GE8x8EB, and GE8x8NB are acceptable for use in Cycle 9.

3.0 ENVIRONMENTAL CONSIDERATION
S This amendment changes a requirement with respect to install 6tior, or use L
cf a~ facility component located within the restricted aree as defined in 10 CFR Part 20 and changes to the surveillance requirements.
The staff has determined that the arrenoment involves no significant increase in the o
L amounts, ano no significant change in the types, of any effluents that may E
be released oft site; and that there shoulc be no significant increase in indivioual or cumulative cccupational radiation exposure.
The Comission has previously issued a proposed finding that this amendment involves no significant hazards consideration, and there has been no public coment on i
such finding. Accordingly, this an.endment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Fursuant to 10 CFR 51.22(b), no environmental impact statenent or environn. ental assessment
' need be prepared in connection with the issuance of the araendment.
a.0 CONCLUSION The Comission trade a proposed determination that this anencrent involves no significant ht.zards consideration which was published in the FEDERAL REGISTER (54 FR 29401) on July 12. 1989, and' consulted with the State of North Carolina.
No public consents or recuests for hearing were receiv'ed, and the State of horth Carolina did not have any conunents.
The staff has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health ano safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in ccrrpliance with the Commission's regulations, and the issuance of the amendirent will not be inimical to the i
comon defense and security or to the health and saf ety of the public.
