REQUEST FOR ADDITIONAL INFORMATION GENERIC LETTER 2006-03 POTENTIALLY NONCONFORMING HEYMC AND MT FIRE BARRIER CONFIGURATIONS JOSEPH M. FARLEY NUCLEAR PLANT, UNIT NOS. 1 AND 2 FOR RENEWED FACILITY OPERATING LICENSE NO. NPF-2, DOCKET NO. 50-348 AND RENEWED FACILITY OPERATING LICENSE NO. NPF-8 DOCKET NO. 50-364 For the Farley Nuclear Plant (FNP), the Promat H board is described as a fire barrier that separates redundant trains within the same fire area (for example, cable tray enclosures). The response states that Promat H board is tested in accordance with Underwriter Laboratories document UL 263, American Society for Testing and Materials document ASTM E119, and the National Fire Protection Association document NFPA 251. Use of these tests and standards identifies fire testing for building members and assemblies, but does not specifically address 1 and 3-hour fire barrier systems protecting electrical raceways.

This issue was discussed during a phone call with the FNP staff on July 27, 2006. The following are follow-up questions from that phone call to confirm the Nuclear Regulatory Commission staffs understanding of the FNP Promat configuration.

1. How was the Promat tested? Confirm that, per the phone call, the ASTM E119 time temperature, full scale fire testing was used.

2. What acceptance criteria were used? Confirm that, per the phone call, the 325 degrees Farenheit temperature criterion was used.

3. How were installed configurations that were different from tested configurations evaluated? Confirm that, per the phone call, the field installation deviations from the tested configurations were evaluated in accordance with the Generic Letter 86-10, Section 3.2.2 criteria.
