84.7 BASES FOR EMERGENCY CONTAINMENT FILTERING SYSTEM, POST ACCIDENT CONTAINMENT VENT SYSTEM, AND CONTROL ROOM VENI'ILATION SYSTEM.
System components are not subject to rapid deterioration, having lifetimes of many years, even under continuous flow conditions.
Visual inspection an operating tests provide assurance of system reliability and will insure early detection of conditions which could cause the system to fail or operate improperly.
The performance tests prove conclusively that filters have been properly instal led, that no deterioration or damage has occurred, and that all components and subsystems operate properly.
The tests are performed in accordance with the methodology and intent of ANSI N510 (1975) and provide assurance that filter performance has not deteriorated below required specification values due to aging, contamination, d'or other effects.
