SUBJECT:

SALEM NUCLEAR GENERATING STATION, UNIT NOS. 1 AND 2, DRAFT REQUEST FOR ADDITIONAL INFORMATION (TAC NOS. MD7874 AND MD7875)

The attached draft request for information (RAI) was transmitted on October 15, 2009, to Mr. Jeff Keenan of PSEG Nuclear LLC (PSEG or the licensee). The draft RAI was transmitted to facilitate the technical review being conducted by the Nuclear Regulatory Commission (NRC) staff and to support a conference call (if needed) with PSEG in order to clarify the licensee's submittals dated April 10, 2008, October 13, 2008, and February 10, 2009, in response to Generic Letter 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems" for Salem Nuclear Generating Station, Unit Nos. 1 and 2. The draft questions were sent to ensure that they were understandable, the regulatory basis was clear, and to determine if the information was previously docketed. Additionally, review of the draft RAI would allow PSEG to evaluate and agree upon a schedule to respond to the RAI.

ACCESSION NO.: ML092880519 OFFICE PDI-2/PM NAME REnnis DATE 10/15/2009 OFFICIAL RECORD COPY DRAFT REQUEST FOR ADDITIONAL INFORMATION RELATED TO RESPONSE TO GENERIC LETTER 2008-01 SALEM NUCLEAR GENERATING STATION, UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311

By letters dated April 10, 2008, October 13, 2008, and February 10, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML081130785, ML082970217, and ML090560529, respectively), PSEG Nuclear LLC (PSEG or the licensee) provided responses to Generic Letter (GL) 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems" (ADAMS Accession No.

ML072910759) for Salem Nuclear Generating Station (Salem), Unit Nos. 1 and 2. Additional information is required for the U.S. Nuclear Regulatory Commission (NRC) staff to determine that the licensee has acceptably demonstrated "that the subject systems are in compliance with the current licensing and design bases and applicable regulatory requirements, and that suitable design, operational, and testing control measures are in place for maintaining this compliance" as stated in GL 2008-01.

Background:

Guidance on NRC staff expectations is provided by Reference 1 which is generally consistent with guidance from the Nuclear Energy Institute (NEI) provided to the nuclear industry. The NRC staff recommends that the licensee consult Reference 1 when responding to the following request for additional information:

1. The GL was intended to address all modes and all operating conditions and it is not limited to events and accidents evaluated in the Updated Final Safety Analysis Report.

Please confirm that all subject systems are evaluated for all modes and all operating conditions.

2. Please demonstrate that adequate net positive suction head margin exists when air ingestion effects are considered in the calculations for the residual heat removal, safety injection, and containment spray pumps.

3. Please briefly summarize the revised fill and vent procedures with respect to guidance for instrumentation lines. Also briefly discuss the details of any confirmatory testing followed by fill procedures.

4. Training was not identified in the GL but it is considered to be a necessary part of applying procedures and other activities when addressing issues identified in the GL.

Please briefly discuss training.
