4. Letter, McIntyre to Quay, "WCAP-14845, ' Scaling analysis for AP600 containment pressure during design basis accidents', Rev 3. errata," DCP/NRCl379, dated June 9,1998.

5. Letter, McIntyre to Quay, " Errata to WCAP-14407, Rev 3, '_WGOTHIC application to AP600'," DCP/NRCl395, dated July 14,1998.

DCP/NRCl400, dated July 22,1998.

Dear Mr. Quay:

Reference 1 provided the NRC assessment of the Westinghouse claim that proprietary information was provided in a letter dated November 21,1994, that contained presentation materials from the November 15 through 17,1994, meeting where the AP600 passive containment cooling system was

- discussed. The NRC assessment was that some, but not all, of the material was sufficiently specific to __

L DCP/NRC1415 NSD-NRC-98-5759 August 17,1998 l the AP600 and the AP600 passive containment cooling testing to reveal distinguishing aspects of the passive containment cooling system and improve a competitors advantage. Our 1995 request,

~

Reference 2, indicated that the material provided in the Westinghouse letter of November 21,1994, was presentation material that was intended for clarification only, not part of the formal review material and requested that the material be returned to Westinghouse. At the time this subject was being discussed with the NRC technical staff, the information was considered to be proprietary by Westinghouse since it contained information that had commercial value to Westinghouse. If this

, presentation material was indeed used by the staff in development of the AP600 final safety evaluation repon, then at this time, almost four years later, this information will no longer considered to be l' proprietary by Westinghouse.

l

Reference 3 provided the NRC assessment of the Westinghouse claim that proprietary information was provided in a letter dated June 20,1995, which provided a copy of WCAP-14382, "%UOTIIIC Code Description and Validation." ne NRC assessment was that all of the material identified as l proprietary, with the exception of Figure 8-19, "Large scale PCS Instrumentation Elevations" would be l accepted as proprietary by the NRC. The Reference 3 pointed out that this same figure was  :

nonproprietary on page 3-12 of WCAP-14382. Figure 8-19, therefore, will no longer considered to be l proprietary by Westinghouse.

Westinghouse has been verbally informed by the NRC that the Westinghouse letter of June 9,1998, l (reference 4), appeared to contain proprietay information that was not clearly identified other than being marked " Westinghouse Proprietary Class 2" on the page and also that there was no affidavit i i

included with the letter. The June 9,1998, letter contained errata for WCAP-14845, Revision 3, which is a proprietary report and for WCAP-14846, Revision 3, which is the nonproprietary version of WCAP-14845. In accordance with Westinghouse company policy, each page of a proprietary repod has " Westinghouse Proprietary Class 2" on the page header. Specific information that is proprietary is then indicated with brackets. It is possible that there will be no information on a page that is marked as being proprietary. In the case of the June 9,1998, letter, none of the errata pages for WCAP-14845 contained Westinghouse proprietary information, thus no affidavit was necessary and the letter can be -

placed in the NRC public document room.

Westinghouse has been verbally informed by the NRC that the Westinghouse letter of July 14,1998, (reference 5), appeared to contain proprietary information that was not clearly ider.tified other than being marked " Westinghouse Proprieta y Class 2" on the page and also that there was no affidavit l- included with the letter. He July 14,1998, letter contained errata for WCAP-14407, Revision 3, which is a proprietary report. In accordance with Westinghouse company policy, each page of a proprietary report has " Westinghouse Proprietary Class 2" on the page header. Specific information that is proprietag is then indicated with brackets. It is possible that there will be no information on a page that is marked as being proprietary. In the case of the July 14, 1998, letter, none of the errata pages for WCAP-14407 contained Westinghouse proprietary information, thus no affidavit was necessary and the letter can be placed in the NRC public document room.

DCP/NRCl415 NSD-NRC-98-5759 August 17,1998 On August 14,1998, Westinghouse was verbally informed by the NRC that the information contained in Chapter 18 of Revision 0 of the AP600 Standard Safety Analysis Report (SSAR) that was submitted to the NRC on June 26,1992, and was requested to be withdrawn by Reference 6, forms the basis of the Chapter 18 of the AP600 Final Safety Evaluation report that will soon be issued by the NRC and therefore cannot be withdrawn without seriously affecting the FSER issuance date. To maintain this information as proprietary, Westinghouse would have to provide a marked proprietary version and a corresponding nonproprietary version of this material. Reference 6 pointed out that Chapter 18 has been entirely reformatted since the SSAR was submitted originally as a result of Westinghouse significantly changing the approach being taken to human factors as a part of design certification. As a result, the information in Revision 0 through 8 of the SSAR is essentially no longer applicable to the AP600 design certification process, except for the information contained in Subsection 18.9.8.1 -

Development of emergency operating procedures and Tables 18.9.8-1 through 18.9.8 Emergency response guidelines, which was declared to be nonproprietary in Reference 6. Given the desire to complete the AP600 FSER and Final Design Approval in a timely manner, Westinghouse will no longer consider the material in Chapter 18 of Revisions 0 through 8 of the SSAR to be proprietary.

! This response addresses the proprietary issues delineated in the references. j sLfh Brian A. McIntyre, Manager  !
