REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of ventilation and air filtration Secondary - None I. AREAS OF REVIEW The function of the spent fuel pool area ventilation system (SFPAVS) is to maintain ventilation, permit personnel access, and control airborne radioactivity in the spent fuel pool equipment areas during normal operation and anticipated operational occurrences and following postulated fuel handling accidents. The staff reviews the SFPAVS from the air intake to the point of discharge where the system connects to the gaseous cleanup and treatment system or the station vents to ensure compliance with the requirements of General Design Criteria (GDCs) 2, 5, 60, and 61. The review includes such components as air intakes, ducts, air conditioning units, filters, blowers, isolation dampers, and exhaust fans. The review of the SFPAVS covers all areas containing or adjacent to the spent fuel pool, including the spent fuel pool cooling pump room. The specific areas of review are as follows: 1. The staff reviews the SFPAVS to determine the safety significance of the system. Based on this determination, safety-related portions of the system are reviewed with respect to functional performance requirements during normal operation, adverse environmental occurrences ,and subsequent to postulated accidents, including loss of offsite power. The staff reviews safety-related portions of the system to ensure that: A. A single, active failure cannot result in loss of the system functional performance capability. 9.4.2-2 Revision 3 - March 2007 B. Failures of nonseismic Category I equipment or components will not affect the SFPAVS. 2. Safety-related SFPAVS portions are also reviewed for the following: A. The capability to direct ventilation air from areas of low radioactivity to areas of potentially higher radioactivity. B. The capability to detect the need for isolation and to isolate portions of the system in the event of failures or malfunctions
