CONTAIRfENT SYSTEMS BASES 3/4.6.1.7 CONTAINMENT PURGE AND EXHAUST ISOLATION VALVES This specification ensures that the containment purge supply and exhaust isolation valves are closed for the ma)ority of the time during normal operation.
It allows for containment purging for safety related reasons.
Safety-related reasons are meant to be the need to improve containment working conditions to perform surveillance and/or maintenance on a safety-related system or piece of equipment..
Examples of improved working conditions include reducing temperature, humidity and airborne activity to permit efficient performance or to significantly reduce occupational radiation exposures. It is intended that purging and venting times will be as short as possible.
Allowing purge operations in Modes 1, 2, 3, and 4 is more beneficial than a
cooldown to Mode 5 from the standpoint of (a) imposing unnecessary thermal stress cycles on the reactor coolant system and its components and (b) reducing the potential for causing unnecessary challenges to the reactor trip and safeguards systems.
The containment purge system is designed in accordance with the requirements of NRC Branch Technical Position CSB 6-4, Rev.
1.
This includes, but is not limited to, an
'analysis of the impact of purging on ECCS performance, an evaluation of the radiological consequences of a design basis accident while purging, and limiting purge operation to using no more than one supply path and one exhaust path at a time.
The purge isolation valves have been demonstrated capable of. closing against the dynamic forces associated with a loss-of-coolant accident and are assured of receiving a
Containment Ventilation Isolation signal.
Reset switches have been protected against inadvertent'se in a manner which facilitates the administrative controls governing their use, The use of the pressure relief (vent) line is allowed for containment pressure control.
The purge and vent isolation valves do not use resilient seating/sealing material and are not subject to the type of environmental degradation common to resilient materials.
