Dear Mr. Hunger:

SUBJECT:

SAFETY EVALUATION OF PECO'S FROSSTEY FUEL PERFORMANCE CODE:

I

_PECO-FMS-0003 (TAC NOS. 65871)

-l RE:

PEACH' BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3 l

The' RRC. staff has completed its review of the Philadelphia Electric Company's (PECo) FROSSTEY fuel performance code. The code was described in a PECo-report PECo-FMS-0003 " Steady-State Fuel Performance' Methods Report" submitted l

by letter dated July.13,-1987.

j As. stated in the enclosed evaluation, the staff concludes thatithe use of ti FROSSTEY, as described in the referenced documents, is acceptable for referencing in the evaluation of Peach Bottom critical power ratio (CPR) analyses.in support of reloads. The use of the FROSSTEY code for the l

i evaluation of gadolinia fuel rods is limited to five percent or less by weight of gadolinia.in U02. 'If PECo wishes to apply the FROSSTEY code to other fuel

, design and safety analyses, i.e., other than core average and hot channel gap conductances for CPR analyses in support of reload analyses, then these additional FROSSTEY applications must be submitted to the NRC staff for review and approval.. Subject to these conditions the NRC staff finds the PEco iFROSSTEY code submittals, as evaluated in the enclosure, to be acceptable for referencing in the Peach Bottom CPR analyses in support of reloading analyses.

Sincerely, j

Dear Mr. Hunger:

SUBJECT:

' SAFETY EVALUATION OF PEC0'S FROSSTEY FUEL PERFORMANCE CODE:

PECO-FMS-0003.(TAC NOS. 65871)

RE:

PEACH BOTTOM ATOMIC F0WER STATION, UNITS 2 AND 3 The NRC staff has completed its review of.the Philadelphia Electric Company's l

(PECo) FROSSTEY fuel performance code. The code was described in a PEco report PEco-FMS-0003 " Steady-State Fuel Performance Methods Report" submitted by letter dated July 13, 1987..

-As stated in the enclosed evaluation, the staff concludes that the use of FROSSTEY, as described in the referenced documents, is acceptable for referencing in the evaluation of Peach Bottom critical power ratio (CPR) analyses in support of reloads. 'The use of the FROSSTEY code for the evaluation of gadolinia fuel rods is limited to five percent or less by weight

If PECo wishes to apply the FROSSTEY code to other fuel design and safety analyses, i.e., other than core average and hot channel gap conductances for CPR analyses in support of reload analyses, then these additional FROSSTEY applications must be submitted to the NRC staff for review and approval.
