Certain of the questions, (specifically Questions 24 and 49) require plant specific responses.
These questions will be addressed during implementation of the "trip two/leave two" strategy in the plant emergency operating procedures.
This implementation will be occurring as part of the overall emergency procedure upgrade program in response to Supplement 1 to NUREG-0737 (currently scheduled for completion in February, 1986).
