ST. -LU:IE PIANT UNIT 2 EMERGENCY PROCEDURE NEER 2-0030132 (AVOWS) REVISION 0 1 ~ 0 SCOPE This procedure provides instructions to be used in the event of an ATWS-The transients which produce most limiting ATWS consequences are covered by this procedure.
2a 0 SYMPZ04MS The following are symptoms, related to the three transients, which would cause a reactor trip.
Any of these symptoms, not accompanied by insertion of all CEA's, are an indication of ATSW:

- 3. 0 AUT(MATIC ACTIONS:
Some of the followf.ng Automatic Actions will occur during the various transients with the absence of a reactor trip:
NOTE:
Any Automatic Actions that should occur and do not, must be manually initiated.

ATMS Arws 5 ~ 0 SUBSE UENT ACTIONS:
I None 6 ~ 0 DISCUSSION:
Tris procedure starts and ends
~doric a transient.
For this reason, there is no subsequent action.
The last immediate action is to refer to the Reactor Trip/Turbine Trip procedure and from there determine the course of action to take.
