Letter from Christopher I. Grimes (NRC) to Addressees, dated April 10, 2006, "NRC Generic Letter 2006-03: Potentially Nonconforming Hemyc and MT Fire Barrier Configurations" On April 10, 2006, the NRC issued NRC Generic Letter (GL) 2006-03, "Potentially Nonconforming Hemyc and MT Fire Barrier Configurations." The GL requested a written response within 60 days in accordance with 10 CFR 50.54, "Conditions of licenses," paragraph (f). The GL requested information regarding the use of Hemyc and MT fire barrier materials and whether they are relied upon for separation and/or safe shutdown purposes. Additionally, the GL requested a description of the controls used to ensure other fire barrier types were capable of providing the necessary level of protection.
Attachment 1 provides the PSEG Nuclear LLC (PSEG) 60 day response to the Generic Letter for Salem Generating Station.
There are no regulatory commitments contained in this letter. Should you have any questions concerning this letter, please contact Paul Duke at (856) 339-1466.

The GL requested a written response within 60 days in accordance with 10 CFR 50.54, "Conditions of licenses," paragraph (f). The GL requested that licensees answer the following questions and provide the information to the NRC with respect to each of their Nuclear Power Plants (NPPs).
The PSEG Nuclear, LLC (PSEG) response to the Generic Letter for Salem Generating Station (SGS) is provided below.
- 1. Within 60 days of the date of this GL, provide the following:
- a. A statement on whether Hemyc or MT fire barriermaterialis used at their NPPs and whether it is relied upon for separationand/orsafe shutdown purposes in accordancewith the licensing basis, including whether Hemyc or MT is creditedin other analyses (e.g., exemptions, license amendments, GL 86-10 analyses).
Response
Neither Hemyc nor MT fire barrier material is used at SGS for electrical raceway fire barrier systems required for separation of redundant trains located in a single fire area.
- b. A description of the controls that were used to ensure that other fire barrier types relied on for separationof redundant trains located in a single fire area are capable of providing the necessary level of protection.
Addressees may reference their responses to GL 92-08 to the extent that the responses addressthis specific issue.
Response
PSEG's response is limited to fire barriers installed on electrical raceways and cable trays relied on to separate redundant trains. This is based on the scope of previous Generic Letters (i.e., Generic Letter 92-08 and Generic Letter 86-10) and information obtained from a May 10, 2006 conference call between Exelon Generation Company, LLC and the NRC staff.
Electrical raceway fire barrier materials used at SGS are based on various configurations of 3M E-50 Series material. This material was installed using the controls and design process established in a Detail Specification Attachment I LR-N06-0257 (S-C-ZZ-NDS-0387, "Design Specification Electrical Raceway Fire Barrier Systems, Salem Generating Station Units"). This specification references Supplement 1 to NRC Generic Letter 86-10 and uses the guidelines of this GL for the testing of Electrical Raceway Fire Barrier Systems and applicable acceptance criteria for tests of bounding configurations.
- 2. Within 60 days of the date of this GL, for those addresseesthat have installed Hemyc or MT fire barriermaterials, discuss the following in detail:
- a. The extent of the installation(e.g., linearfeet of wrap, areasinstalled, systems protected),
Response
Not applicable. Neither Hemyc nor MT fire barrier material is used at SGS for electrical raceway fire barrier systems required for separation of redundant trains located in a single fire area.
- b. Whether the Hemyc and/orMT installed in theirplants is conforming with theirlicensing basis in light of recent findings, and if these recent findings do not apply, why not,
Response
Not applicable. Neither Hemyc nor MT fire barrier material is used at SGS for electrical raceway fire barrier systems required for separation of redundant trains located in a single fire area.
- c. The compensatory measures that have been implemented to provide protection and maintain the safe shutdown function of affected areasof the plant in light of the recent findings associatedwith Hemyc and MT installations,including evaluations to support the addressees'conclusions, and
Response
Not applicable. Neither Hemyc nor MT fire barrier material is used at SGS for electrical raceway fire barrier systems required for separation of redundant trains located in a single fire area.
- d. A description of, and implementation schedules for, corrective actions, including a description of any licensing actions or exemption requests needed to support changes to the plant licensing basis.
Response
Not applicable. Neither Hemyc nor MT fire barrier material is used at SGS for electrical raceway fire barrier systems required for separation of redundant trains located in a single fire area.
Attachment I LR-N06-0257
- 3. No laterthan December 1, 2007, addresseesthat identified in l.a. Hemyc and/or MT configurationsare requestedto provide a description of actions taken to resolve the nonconforming conditions described in 2.d.
Response
Not applicable. Neither Hemyc nor MT fire barrier material is used at SGS for electrical raceway fire barrier systems required for separation of redundant trains located in a single fire area.
