REQUEST FOR ADDITIONAL INFORMATION FOR SALEM NUCLEAR GENERATING STATION UNITS 1 AND 2 LICENSE RENEWAL APPLICATION (TAC NOS. ME1834 AND ME 1836)

Dear Mr. Joyce:

By letter dated August 18, 2009, as supplemented by letter dated January 23, 2009, Public Service Enterprise Group Nuclear, LLC, submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 for renewal of Operating License Nos. DPR-70 and DPR-75 for Salem Nuclear Generating Station Units 1 and 2, respectively. The staff of the U.S. Nuclear Regulatory Commission (NRC or the staff) is reviewing this application in accordance with the guidance in NUREG-1800, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants. During its review, the staff has identified areas where additional information is needed to complete the review. The staffs request for additional information is included in the Enclosure. Further requests for additional information may be issued in the future.

Items in the enclosure were provided to John Hufnagel and other members of your staff, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me by telephone at 301-415-2981 or by e-mail at bennett.brady@nrc.gov.

ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION FOR SALEM NUCLEAR GENERATING STATION UNITS 1 AND 2 LICENSE RENEWAL APPLICATION RAI 3.3.2-01

Background:

Salem Nuclear Generating Station (SNGS) license renewal application (LRA) Tables 3.3.2-1 (Auxiliary Building Ventilation), 3.3.2-7 (Containment Ventilation), 3.3.2-15 (Fuel Handling Ventilation), 3.3.2-26 (Switchgear and Penetration Area Ventilation) contain aging management review (AMR) lines for elastomer door seals and flexible connections exposed to air with borated water leakage. For this combination of component, material, and environment, the LRA states that there is no aging effect and no aging management program (AMP) is required.

These same SNGS LRA tables contain elastomer door seals and flexible connections exposed to air/gas - wetted (internal). For this combination of component, material, and environment, the LRA credits the Periodic Inspection Program to manage hardening and loss of strength due to elastomer degradation.

Issue:

The LRA does not provide a technical basis for concluding there is no aging effect for elastomer door seals and flexible connections exposed to air with borated water leakage.

Also, it is not clear to the staff whether the elastomer door seals and flexible conduit determined to have no aging effect when exposed to air with borated water leakage are the same components as those exposed to air/gas - wetted internals.

Request:

a) Provide the technical basis for concluding that elastomer door seals and flexible conduit have no aging effect when exposed to air with borated water leakage.

b) Clarify whether the components exposed to air with borated water leakage are the same as those exposed to air/gas - wetted (internal). If they are the same, explain why one environment results in an aging effect and the other does not.

RAI 3.3.2-02

Background:

SNGS LRA Table 3.3.2-26 (Switchgear and Penetration Area Ventilation) contains AMR lines for elastomer door seals and flexible connections exposed to air with borated water leakage and to air/gas - wetted.

Issue:

The LRA does not provide sufficient information for the staff to evaluate the effect of these environments for components in this system.

Request:

Explain the basis for including these environments for elastomer door seals and flexible connections in the Switchgear and Penetration Area Ventilation System, in particular, how the elastomers are exposed to the borated water leakage and wetted air/gas mixture.
