January 20,-1988 Docket No. 50-277/278 Mr. Edward G. Bauer, Jr.
Vice President and General counsel i
Philadelphia Electric Company 2301 Market Street Philadelphia,-Pennsylvania 19101
Dear Mr. Bauer:
SUBJECT:
PECO FROSSTEY FUEL PERFORMANCE CODE (TAC NO. 65871)
As a result of the staff consultant's review at PNL, we find that the.
following additional information is needed to facilitate the review of the PECo FROSSTEY fuel perfomance code described in the PECo report PECo-FMS-003.
1.
Does the licensee intend to use FROSSTEY for input to LOCA' analyses and the determination of end-of-life internal rod pressure? If'so, it should be noted that additional code verification (both in terms of themal and fission gas release) is needed to demonstrate that-the conservatisms in the code and the code input are sufficient.to account for the overall predictive uncertainties in the LOCA and internal rod pressure analyses.
If not, please state which licensing analyses the FROSSTEY code will be used to support, e.g., in reload applications, would it support the analyses for one-percent cladding strain or hot channel analyses of CPR7 J
2.
In order to evaluate the licensee's proficiency in the use of FROSSTEY, please provide the FROSSTEY input used to calculate hot channel gap conductance and volume average temperature versus burnup for batches 8 and 13 in the submitted report.
How many individuals (including any non-PECo personnel) were involved in the modeling of input to the code?
Indicate their particular contribution to each of the four test exercises.
Please indicate what steps PEco has taken to ensure that the level of expertise which has been demonstrated in this series of exercises-will be maintained in the future.
Should you have questions, please feel free to contact us.
20 Sincerely,
^
