Dear Ms. Johnson:
This letter is in regard to the Dresden, Units 2 and 3, and LaSalle, Unit 2, plant-specific probabilistic risk assessment (PRA) models that Commonwealth Edison Company (ComEd) provided to the NRC.
These models have.been included in the NRC's "library" of PRA models that are developed using the "Systems Analysis Programs for Hands-on Integrated Reliability Evaluations" (SAPHIRE) code.
This letter is to inform ComEd of NRC's intention of placing these PRA models on the docket and in the public document room in 30 days from the date of this letter.. If ComEd deems the PRA models contain proprietary information, it must submit an affidavit as.required by 10 CFR 2.-790 within the 30 days.
NRC will review the submittal and inform ComEd of the result.
Please ~ontact me at (301) 415-1322 if you have any questions on this subject.
Sincerely, ORIGINAL SIGNED BY:
