23A6100 Rev. 4 ABWR scad:rd sacty An:tysis Rep:rt (d) On manualinitiation, the clean area HVAC system can be put into high radiation mode. On switch over, exhaust fans stop and emergency filter train starts. System pressurizes clean areas of the senice building.

(e) Instrumentation is provided for the monitoring system operating variable during normal station operating conditions. The loss of airflow, high and low system temperature, and high differential pressure across various filters are annunciated on the local control panel. Trouble on the local panelis annunciated in the main control room.

(8) All power and water is provided from non-safety-related sources.

(9) The COL applicant will provide a detailed P&ID, system flow rates an equipment list, and compliance with RG 1.140 and toxic gas protection requirements for the Senice Building HVAC system, including the TSC and the OSC, for NRC review. (See Subsection 9.4.10.1 for COL L.icense Information.)

9.4.8.3 Safety Evaluation (1) The Senice Building HVAC System is not safety-related and is not required to assure either the integrity of the reactor coolant pressure boundary or the capability to shut down the reactor and maintain it in a safe shutdown conditions.

(2) Pressure control dampers are employed between clean and potentially contaminated areas and are of the backflow type and fail closed. This minimizes the backflow of contaminated air to clean areas when there is a loss of power and subsequent fan sptem shutdown.

(3) The system incorporates features to assure its reliable operation over the full range of normal station conditions.

(4) Clean areas are provided with emergency filtration system and a high radiation mode of operation.

> iNssRT A 9.4.8.4 Testing and Inspection All equipment is factoryinspected and tested in accordance with the applicable equipment specifications and codes. System ductwork and erection of equipment is inspec:ed during various construction stages. Preoperational tests are performed on all mechanical components and the system is balanced for the design air, and water flows and system operating pressures. Controls, interlocks and safety devices on each system -

are checked, adjusted, and tested to ensure the proper sequence of operation. A final integrated preoperational test is conducted with all equipment and controls operational to verify the system performance.

.1 (5)

Since there are no sources of radioactivity inside the Service Building, automatic isolation provisions are not required. However, if radiation levels inside the Service Building are found to be high due to leakage from the secondary containment or from the Turbine Building, the Service Building HVAC system can be manually isolated to prevent releases to the environment.
