Weber of Oak Ridge National Laboratory for his use in the AP600 containment pH assessment.

Enclosure 2 Request for Additional Information 470.21 requested information regarding fission product source rates into the various compartments in the containment and the distribution of the fission product groups throughout a transient sequence. The requested information was transmitted in an attachment to Westinghouse letter NTD-NRC-95-4431, dated April 7,1995. This information has been updated to correspond with Revision 8 of the AP600 PRA and is provided as Enclosure 2.
