Mr. Nicholas J. Liparulo, Manager-Nuclear Safety and Regulatory Analysis Nuclear and Advanced Technology Division Westinghouse Electric Corporation P.O. Box 355 Pittsburgh, PA 15230
SUBJECT:
FOLLOWON QUESTIONS REGARDING THE EX-VESSEL SEVERE ACCIDENT ANALYSIS FOUND IN THE PROBABILISTIC RISK ASSESSMENT (PRA) FOR THE AP600
Dear Mr. Liparulo:
As a result of its review of the June 1992, application for design certifica-tion of the AP600, the staff has determined that it needs additional informa-tion.
Specifically, the enclosure to this letter contains requests for additional information concerning ex-vessel severe accident analysis found in the AP600 PRA.
You have requested that portions of the information submitted in the June 1992, application for design certification be exempt from mandatory public disclosure. While the staff has not completed its review of your request in accordance with the requirements of 10 CFR 2.790, that portion of the submitted information is being withheld from public disclosure pending the staff's final determination. The staff concludes that these followon ques-tions do not contain those portions of the information for which exemption is sought.
However, the staff will withhold this letter from public disclosure for 30 calendar days from the date of this letter to allow Westinghouse the opportunity to verify the staff's conclusions.
If, after that time, you do not request that all or portions of the information in the enclosures be withheld from public disclosure in accordance with 10 CFR 2.790, this letter will be placed in the Nuclear Regulatory Commission Public Document Room.
If you have any questions regarding this matter, you may contact me at (301) 415-1132.
Sincerely, original signed by:
Joseph M. Sebrosky, Project Manager Standardization Project Directorate Division of Reactor Program Management Office of Nuclear Reactor Regulation Docket No.52-003
