SUPPLEMENTAL INFORMATION FOR REQUEST FOR LICENSE AMENDMENT AUXILIARY BUILDING VENTILATION SALEM GENERATING STATION UNITS 1 AND 2 FACILITY OPERATING LICENSE NOS. DPR-70 AND DPR-75 DOCKET NOS. 50-272 AND 50-311 By letter dated January 7, 1999, Public Service Electric and Gas Company (PSE&G) provided the Nuclear Regulatory Commission (NRC) with the additional information relative to the PSE&G proposed amendment to modify Technical Specification 3/4 7.7 "Auxiliary Building Exhaust Air Filtration System." (TAC Nos.

M99875 and M99876). On February 3, and 9, 1999, conference calls were held between members of my staff and NRC personnel. This letter documents the changes agreed to between my staff and the NRC. Specifically, the proposed amendment is revised to delete the requirement to have a slight negative pressure between the auxiliary building and the outside atmosphere. As discussed in the February 3 conference call, this requirement is not a part of the original Salem Technical Specifications requirements or the current limiting condition for operation for the Auxiliary Building Ventilation System. Additionally, the phrase "in accordance with ANSI N510-1975" is deleted from Insert Cb 1 and Cb 2. This phrase was moved to the Technical Specification Bases with NRC approval on December 1, 1976.

Attachment I contains the revised limiting condition for operation submitted in our January 7, 1999 letter (Ref: LR-N990006). PSE&G has reviewed the original no significant hazards evaluation submitted in support of our original submittal (LR-N97 488), and determined that it remains valid .

d. After maintenance affecting the flow distribution, verify that the airflow distribution of the system is acceptable when tested in accordance with Regulatory Guide 1.52, Revision 2, 1978 Section C.5.b.
e. After any structural maintenance on the HEPA or carbon adsorber unit mounting frames or housing, perform tests as required by surveillance 4.7.7.1.b.1 through 4.7.7.1.b.4.
f. After operation of Auxiliary Building normal flow path through the carbon adsorber, prior to mode 4 entry, verify the carbon adsorber will remove ~99% of a halogenated hydrocarbon refrigerant test gas when in-place leak tested at a flow rate of 21,400 CFM +/-10%.
g. After operation of containment purge exhaust flow path through the carbon adsorber, prior to mode 4 entry, verify the carbon adsorbers will remove ~99% of a halogenated hydrocarbon refrigerant test gas when in-place leak tested at a flow rate of 21,400 CFM +/-10%.
