20555 Attention:
Mr. Frank J. Miraglia, Chief Licensing Branch 3 Division of Licensing Gentlemen:
ADDITIONAL INFORMATION ENVIRONMENTAL QUALIFICATION NO. 2 UNIT SALEM NUCLEAR GENERATING STATION Public Service Electric and Gas hereby submits, in the en-closure to this letter, a summary listing in terms of safety significance of those Category 1.1 and 1.2 items identified in our submittal of September 18, 1980.
In response to the September 26, 1980 telephone conversation with members of your staff, this list addresses compliance with NUREG-0588 and additional action to be taken.
In some cases compliance with NUREG-_0588 not required since plant safety would not be affected by equipment failure and sufficient information is available for the operator.
In such cases, pro-cedures have been revised to advise the operator.
In other cases, additional information to demonstrate compliance with NUREG- 05_88 will be submitted by November 1, 1980.
The comments section indicates the actions that will be taken if this additional in-formation does not show compliance with NUREG-*0-5 8~. The Detailed information can be found in our September 19, 1980 submittal in the justification section (Section 3) for each item.

SALEM GENERATING STATION UNIT NO. 2 ENVIRONMENTAL QUALIFICATION REVIEW Compliance with NUREG-0588 The follow1ng information provides a more definitive statement on compliance with various sections of NUREG-0588.
1.1 LOCA Qualification Profile The Salem LOCA profile was calculated by Westinghouse utilizing the methodology described in WCAP-8312A for calculating LOCA mass and energy release. Appendix A to NUREG-0588 indicates that this is acceptable to*
the Staff. The COCO model described in WCAP's 8327 and 8936 was used to establish the containment pressure and temperature time-dependent varia-tions following a LOCA.
Although this model has not received generic approval from the Staff, the NRC has found it acceptable on a number of plants including Salem as indicated in the Safety Evaluation Reports.
We believe that this is an acceptable approach in meeting the NUREG-0588 LOCA guidelines.
1.2 MSLB Qualification Profile The Salem MSLB profile was calculated by W~stinghouse utilizing the methodology described in WCAP 8822 for calculating the MSLB mass and energy release. The COCO model described in WCAP's 8327 and 8936 was used to establish the containment pressure and temperature time-dependent variations following an MSLB.
Although this model has not received generic approval from the Staff, the NRC has found it acceptable on a number of plants including Salem as indicated in the Safety Evaluation Reports.
The Salem information and methods were described in FSAR responses to Questions 5.62, 5.63, 5.82, 5.83, 5.84, 5.85.
In addition the NRC Staff themselves performed a confirmatory MSLB analysis utilizing their assumptions and the Contempt code for Salem.
The review of equipment qualification was done in accord with the values determined by the NRC and indicated in the Safety Evaluation Report.
The MSLB qualification profile is in compliance with NUREG~0588 requirements.
i.. 1.3 Chemical Spray The Salem review and requirements address chemical sprays in the manner prescribed by NUREG-0588 including single failure.
1.4 Radiation Doses The Salem review and requirements address radiation doses in the manner prescribed by NUREG-0588.
This includes the proper source tenns for both inside and outside containment and beta doses per the applicable requirements.
Items 1.5, 2, 3, 4 and 5 have been adequately addressed in our 9/19/80 sub-mitta 1.
