Seabrook Station License Renewal Application Request for Additional Information Set 3 RAJ 2.3.3.15-1 License renewal application (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 aging management (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.
RAJ 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 it ***
Yard hydrants are provided at intervals of 250 ft along the fire protection water supply loop, approximately 40 ft from the buildings. The lateral to each yard hydrant is provided with an isolation valve to facilitate hydrant maintenance and repairs without shutting down any part of the fire water supply system... "
The staff requests that the applicant verify whether the yard hydrants and post indicator valves are in the scope of license renewal in accordance with 10 CFR 54.4(a) and whether they are subject to an AMR in accordance with 10 CFR 54.21 (a)(1). 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.
RAJ 2.3.3.15-3 Section 9.5.1.6, "Fire Protection of Specific Plant Areas;' of the Seabrook Station Safety Evaluation Report (NUREG-0896), dated March 1983, on page 9-48, states that"... the applicant committed to provide oil collection systems for each reactor coolant pump in accordance with Section 111.0 Appendix R..:' LRA Section 2.3.3.15 did not discuss scoping and screening results of reactor coolant pump (RCP) oil collection systems and their associated components.
The staff requests that the applicant verify whether the RCP oil collection systems and their associated components 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 RCP oil collection systems and their associated components 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.

RAI2.4.1-1 Please clarify if there are any trash racks, basket strainers, traveling screens or any other debris prevention/removing mechanisms that are part of the Intake Transition Structure that would be required to be in scope of license renewal in accordance with 10 CFR 54.4. If so, also identify the applicable aging effects and the aging managing program (AMP) related to these components.
RAI2.4.1-2 Please confirm whether the following components credited for flood protection per updated final safety analysis report (UFSAR) Section 3.4.1.1 would be required to be in scope of license renewal in accordance with 10 CFR 54.4.

- The rolling steel door in the Fuel Storage Building (located at elevation 20 feet 6 inches MSL),
- The double doors into the entrance vestibule of the Equipment Vault section of the Primary Auxiliary Building (located at elevation 20 feet 8 inches MSL).
RAI2.4.1-3 LRA Section 2.4.1 states that only the foundations of the fire protection water storage tanks are included in the scope of license renewal and subject to an AMR. Please provide additional information on the structural configuration of the tanks and the foundations, specifically. if there is any steel framing attached to the tanks that would provide additional support consistent with 10 CFR 54.4(3).

RAI2.4.6-2 LRA Section 2.4.6 states that the BORAFLEX utilized in the region 2 racks is not credited with the neutron-absorbing capacity in the criticality analyses and therefore will not be managed for reduction of neutron-absorbing. However, UFSAR Section 9.1.2.1 states that the "Region 2 spent fuel racks contain BORAFLEX as a neutron absorbing material to assure a Keff < 0.95."
Please clarify this discrepancy and confirm the inclusion or justify the exclusion of the BORAFLEX from the scope of license renewal and subject to an AMR.
