DCP/NRCl425 NSD-NRC-98-5768 Docket No.: 52-003 August 20,1998 Document Control Desk U. S. Nuclear Regulatory Commission Washington, DC 20555 ATTENTION: T. R. Quay
SUBJECT:
RESPONSE TO NRC LETTERS CONCERNING REQUESTS FOR WITHHOLDING INFORMATION
Reference:
- 1. Letter, Magruder to Liparulo, " Request for withholding information from public disclosure for Westinghouse AP600 design letter of July 13,1995," dated September 14, 1995.
- 2. Letter, McIntyre to Quay, " Response to NRC letter of August 23,1995, ' Request for withholding information in the design certification application for the AP600,"'
DCP/NRC1400, dated July 22,1998.
- 3. Letter, Huffman to Liparulo, " Request for withholding information from public disclosure for Westinghouse AP600 design letter of July 10,1995," dated September 28,1995.
Dear Mr. Quay:
Reference 1 sets forth the NRC assessment of the Westinghouse claim for treatment of proprietary information submitted by Westinghouse in a letter dated July 13,1995, which letter provided Westinghouse report WCAP-14425, " Evaluation of the AP600 Conformance to Inter-System Loss of Coolant Accident Acceptance Criteria", July 1995. The NRC assessment was that the P&lD's for the Normal Residual Heat Removal System (Figure 3-1) and the Primary Sampling System (Figure 3-4) did not reveal distinguishing aspects of the AP600 design and therefore did not contain trade secrets or proprietary information. Figure 3-1 is nearly identical to nonproprietary Figure 5.4-7 of Revision 24 of the SSAR and can therefore be considered nonproprietary. Figure 3-4 was taken from Figure 9.3.3-2 of Revision 0 of the SSAR. The early SSAR figures contained signiGcantly more information than the simplined drawings that traditionally appeared in safety analysis reports as discussed in reference 2. This figure has been replaced in the SSAR by a simplined sketch and, as discussed in Reference 2, Westinghouse still considers this Hgure to be proprietary due to the level of detail provided in the Ogure.

a DCP/NRCl425 NSD-NRC-98-5768 August 20,1998 Reference 3 sets forth the NRC assessment of the Westinghouse claim for treatment of proprietary information submitted by Westinghouse in a letter dated July 10,1995, which letter provided Westinghouse proposed markups of SSAR sections 6.2 and 6.4. The NRC assessment was that the only matcrial identified as proprietary was figure 6.4-2, the main centrol room habitability piping and instrumentation diagram, P&lD. The main control room P&lD contained in the July 10,1995, letter is i
no longer representative of the AP600 design and no longer considered proprietary by Westinghouse and can be placed in the ublic document room.
