==SUBJECT:==
UPDATED AP600 FISSION PRODUCT TRANSPORT CALCULATIONS AND FISSION PRODUCT SOURCE RATES
}

==Dear Mr. Quay:==

i Two enclosures are provided in this letter pertaining to AP600 Fission product transport calculations                      !
and fission product source rates.                                                                                          :
Enclosure 1     AP600 fission product transport calculations, as requested by the NRC for the AP600                        ;
containment pH assessment by Oak Ridge National Laboratory, was previously j                         transmitted to the NRC in Westinghouse letter NTD-NRC-94-4308, dated September 23, 1994. The transient information was taken from the MAAP4 analysis for case 3BE. base of revision 1 of the AP600 Probabilistic Risk Assessment (PRA).
Enclosure 1 of this letter is the updated transient information which corresponds to Revision 8 of the AP600 P'RA. This updated data is taken from the MAAP4 analysis for Case 3BE-2 as presented in PRA Chapter 34, subsection 34.4.1.2. Please send a copy of this updated information to Mr. C. F. 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.

PROPRIETARY INFORMATION NOTICE Transmitted herewith are proprietary and/or non-proprietary versions of documents furnished to the NRC in connection with requests for generic and/or plant specific review and approval.
In order to conform to the requirements of 10 CFR 2.790 of the Commission's regulations concerning the protection of proprietary information so submitted to the NRC, the information which is proprietary in the proprietary versions is described in the non-proprietary versions. The justification l        for claiming the information so designated as proprietary is:
(a)   the information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.
and (c)   Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of l                        quality, or licensing a similar product.
These lower case letters refer to the types of information Westinghouse customarily holds in            ,
confidence iden:ified in Section (4)(ii)(a) through (4)(ii)(f) of the affidavit accompanying this transmittal pursuant to 10 CFR2.790(b):1).
