A.
PURPOS.E 1.
This procedure provides actions to cool down and depressurize the RCS to cold shutdown conditions while minimizing loss of RCS inventory.
B.
ENTRY CONDITIONS This procedure is entered from:
1.
ECA-3.1, (SGTR WITH LOSS OF REACTOR COOLANT - SUBC00 LED RECOVERY DESIRED), Step 20,'when RWST level is low without a cor?:esponding increase in Containment sump level.
2.
ECA-3.1.-(SGTR WITH LOSS OF REACTOR COOLANT - SUBCOOLED RECOVERY DESIRED), Step 20, when.the ruptured S/G 1evel is high and Plant staff c.
selects saturated recovery method.
- This procedure has been extensively revised.
