- 2. As indicated in the FSAR, currently, the containment purge isolation valves are automatically closed by either a high containment pressure signal or high radia tion signal or both. The experience gained from the"TMI-2 accident indicates that a containment isolation signal initiated by safety injection actuation is also needed to.close the purge valves. Therefore, provide your plan for modifying the control system to isolate containment whenever safety injection is initiated.
