REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION SEABROOK STATION, UNIT NO.1 DOCKET NO.: 50-443 TAC NO.: ME4028 Office of Nuclear Reactor Regulation Division of Risk Assessment Fire Protection Branch For Seabrook Station, Unit No.1 (Seabrook), the staff reviewed the license renewal application (LRA); drawings; updated final safety analysis report (UFSAR), Section 9.5.1, and Fire Protection Evaluation and Comparison to BTP APCSB 9.5-1, Appendix A Report, i.e., approved fire protection program, a point-by-point comparison with Appendix A to the Branch Technical Position (BTP), Auxiliary and Power Conversion Systems Branch (APCSB), 9.5-1, Guidelines for Fire Protection for Nuclear Power Plants, May 1, 1976. The staff also reviewed the following fire protection documents cited in the current licensing basis listed in the Seabrook Operating License Condition 2.F:

Safety Evaluation Report, dated March 1983; Supplement 4, dated May 1986; Supplement 5, dated July 1986; Supplement 6, dated October 1986; Supplement 7, dated October 1987; and Supplement 8, dated May 1989.

The staff has identified that fire protection systems and components discussed in the following sections have been excluded from the scope of license renewal and an aging management review (AMR). These systems and components were not included in the license renewal boundaries and appear to have fire protection intended functions required for compliance with Title 10 of the Code of Federal Regulations (CFR) 50.48, Fire protection, as stated in 10 CFR 54.4. Therefore, in order to complete our review, the staff requires responses to the following requests for additional information (RAIs):

RAI 2.3.3.15-1 LRA drawing PID-1-FP-LR20270 shows that sprinkler systems at locations C-4 to H-4 are out of scope (i.e., not colored in red). The staff requests that the applicant verify whether these sprinkler systems installed in various areas of the plant are in the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.

RAI 2.3.3.15-2 LRA drawing PID-1-FP-LR20274 shows that several yard fire hydrants and post indicator valves are out of scope (i.e., not colored in red). The staff believes that yard fire hydrants and post indicator valves have the fire protection intended functions required to be compliant with 10 CFR 50.48 as stated in 10 CFR 54.4. The fire hydrants and post indicator valves also serve as the pressure boundary for the fire protection water supply system. Further, NUREG-0896, Safety Evaluation Report related to the operation of Seabrook Station, Units 1 and 2, dated March 1983, Section 9.5.1.5, Fire Detection and Suppression, on page 9-47, states that Yard hydrants are provided at intervals of 250 ft along the fire protection water supply loop, ENCLOSURE

Automatic fire detection is provided by ionization smoke detectors. Manual protection is provided by standpipe and hose stations and portable extinguishers LRA Section 2.3.3.15 did not discuss scoping and screening results of Division I and Division II switchgear rooms standpipe and hose stations.

The staff requests that the applicant verify whether the Division I and Division II switchgear rooms standpipe and hose stations are in the scope of license renewal in accordance with

10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). If the Division I and Division II switchgear rooms standpipe and hose stations are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.

If they are excluded from the scope of license renewal and are not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.

RAI 2.4-1 LRA Section 2.4, Scoping and Screening Results: Structures and Structural Components, provides the methodology for determining that structures and components including fire barriers are within the scope of license renewal. LRA Sections 2.4.1 to Section 2.4.8 and their associated tables provide the results of scoping and screening of structures including fire barriers. However, scoping and screening results do not specify each type of fire barrier present in various fire areas of the plant that performs a fire barrier function, e.g., fire penetration seals, fire resistance coating on structural steel supporting fire barriers, fire rated doors, fire dampers, electric raceway fire barrier material or fire wrap. The staff requests that the applicant provide details of the fire barrier type and material in each plant fire area within scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). For any fire barrier type or material that is excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
