Gentlemen:

COMMENTS ON PROPOSED NUREG-1465 ACCIDENT SOURCE ' TERMS FOR LIGHT-WATER l

. NUCLEAR POWER PLANTS in the July 26,1992 Federal Register, the NRC requested comments on draft NUREG-- 1 1465," Accident Source Terms for Light-Water Nuclear Power Plants." The information in this report provides revised accident source terms for light-water reactors (LWR) to; 4 replace those given in report TID 14844, issued in 1962. When final, these~ source- ,

terms are to be implemented through a rulechange to 10CFR50 for use in the design _

and licensing of future light-water reactor nuclear power plants.

NUREG - 1465 does not clearly specify the application of containment: leak rate assumptions for the containment pressure analysis that would be. required for a complete licensee analysis of a Loss of Coolant Accident (LOCA) under this guidance.

This information would be essential for an existing nuclear. plant that wanted to voluntarily adopt this process. -We suggest the NRC provide clarification on these j points in this guidance for each type of existing containment design to identify the regulatory restrictions that would be applied in voluntary adoption.

We support the NUMARC comments on this subject sent separately to the NRC. If you .

have any questions, please contact us. .

1 Very truly yours, ,
