By letter dated July 17, 2012, PSEG submitted a license amendment request for Salem Generating Station Units 1 and 2 (ADAMS Accession No. ML12199A426), to revise Technical Specification (TS) 3/4.7.6.1 (Unit 1) and 3/4.7.6 (Unit 2), "Control Room Emergency Air Conditioning System," by removing the separate action for securing an inoperable Control Area Air Conditioning (CAACS) and Control Room Emergency Air Conditioning System (CREACS) isolation damper *in the closed position and entering the actions for an inoperable control room envelope boundary. The NRC staff has reviewed the information submitted by the licensee, and based on this review, determined the following information is required to complete the evaluation.

RAI 1: Salem Unit 1 TS 6.18 and Unit 2 TS 6.17 contain the Control Room Envelope (CRE)

Habitability Program. Element "a" of the program requires a definition of the CRE and CRE boundary. The amendment request did not discuss the current definition of the CRE, whether or not the isolation dampers in question are defined as part of the CRE boundary, or whether or not the CRE was being redefined.

Please clarify whether or not the isolation dampers are currently defined as part of the CRE boundary.

Response

The Control Room Envelope (CRE) boundary is defined in the Salem Unit 1 and 2 TS Bases and procedure ER-AA-390, Control Room Envelope Habitability Program, as follows:

"A combination of walls, floor, roof, ducting, doors, penetrations and equipment that physically form the CRE."

Procedure ER-AA-390-1 001, Control Room Envelope Habitability Program Implementation, states the following in Step 4.1.2:

LAR 512-02 LR-N13-0007

" ... the ventilation system duct/plenums and isolation dampers that separate the CRE from potentially contaminated spaces, form a critical part of the CRE boundary."

The isolation dampers between the Control Area Air Conditioning System (CAACS) and the Control Room Emergency Air Conditioning System (CREACS) are currently considered part of the CRE boundary for Salem. Therefore the definition of the Salem CRE boundary is not being redefined as a resL!lt of this license amendment request.
