If these components are excluded from the scope of license renewal, please provide a basis for their exclusion. Please include a discussion on whether deterioration related failure of these components could result in compromised performance of the Control Building Heating, Ventilating, and Air Conditioning (HVAC) System or allow intrusion of missile/debris that could adversely affect in-scope components.
RAI-2.3.3.12-1 Drawing LR-PVNGS-HA-02-M-HAP-001 at locations H-8 and F-6 show fire dampers HAN-M05 and HAN-M29A that are not highlighted. Please provide the basis for excluding these fire dampers from the license renewal scope. Please include in your discussion, a description of the airflow entering into the corridor that then passes through fire damper HAN-M29A into the west piping penetration room.
RAI-2.3.3.15-1 Drawing LR-PVNGS-HD-01-M-HDP-001 shows fixed louver assemblies at drawing zones/locations D-1 and B-3 are not color coded as being in scope. If these components are excluded from the scope of license renewal, please provide a basis for their exclusion. Please include a discussion on whether deterioration related failure of these components could result in compromised performance of the Diesel Generator Building HVAC System or allow intrusion of missile/debris that could adversely affect in-scope components.
RAI-2.3.3.17-1 Drawing LR-PVNGS-HT-01-M-HTP-001 at zone/location B-2 shows fire dampers HTN-M39-S3M and HTN-M40-S3M highlighted as being in scope. Please discuss whether these fire dampers are mounted in the fire barrier boundary (wall) and if the downstream backdraft dampers/ducting should also be shown in scope as needed to maintain the fire barrier boundary integrity. If the downstream backdraft dampers/ducting are excluded from the scope of license renewal, please provide a basis for their exclusion.
