SUBJECT:
REPORT ENTITLED 'AN ASSESSMENT OF EX-VESSEL STEAM EXPLOSIONS IN THE AP600 ADVANCED PRESSURIZED WATER REACTOR'
Dear Mr.-Liparulo:
The staff has asked a contractor to perform analyses of ex-vessel steam explosions for the AP600. A brief discussion of these analyses will be i~luded in the staff's final safety evaluation report. The report from the sontractor is enclosed for your information.
If you have any questions concerning this report please contact Michael Snodderly of the Containment Systems and Severe Accident Branch at (301) 415-2047.
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 the enclosed report does 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 enclosure be withheld from publir 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.
Sincer y,
