SUBJECT:

SAFETY EVALUATION FOR TOPICAL REPORT PECO-FMS-0004 "METHODS FOR  ;

PERFORMING BWR SYSTEM TRANSIENT ANALYSIS" (TAC NOS. 66534/66535)

RE

PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3 The Philadelphia Electric Company topical report PECo-FMS-0004 was submitted

, on September 28, 1087 and was supplemented on June 6 and October 11, 1988. .

4 The purpose of the report is to demonstrate, per Generic letter 83-11, that  ;

, PECo has the technical expertise to perform transient systems analysis with j the RETRAN computer code for the Peach Bottom units. The NRC staf* m aided  :

i in its review of the topical report with technical assistance from its ,

i consultant International Technical Services. Inc. The staff has concluded '

I that PECo has demonstrated its knowledge of the RETRAN computer code and

nodels . The PECo report is the fourth in a series of six reports describing '

j the overall methodology for performing in-house licensing analyses for the l Peach Bottom units. The report does not by itself contain sufficient material .

! to justify the models for licensing applications. Additional information to  ;

meet the interface requirements between the FPS-0004 and FMS-0006 reports, as  ;

discussed in the enclosed evaluation, must be provided in the FMS-0006 report '

t when it is submitted. Therefore, the staff's approval is limited to PEco's I

demonstration of competence to use the RETRAN cortputer code for Peach Bottom. i Therefore, consistent with these plans to review the interface information .

4 during the FMS-0006 review, this completes our review of your September 28,  !
