The next event is a malfunction after EOP entry 4 and this would be event 7 (CS-125B).

You need to have a Critical Task list table (see example below from RB). It contains each CT and its basis as well as the footnote for post-scenario CTs.

Critical Task Number Description Basis Per EOP basis, An area temperature above its maximum normal operating level is an indication that steam from a primary system may be discharging into the secondary containment. As temperatures Per EOP-3, close one RWCU continue to increase, the continued isolation valve (G33-MOV-1 OR operability of equipment needed to carry 1 G33-MOV-4) after failure to close on out EOP actions may be compromised.

group 15 isolation before completion High area temperatures also present a of step 5.9 of AOP-3 (EOP-3, SC-4) danger to personnel, a consideration of significance since access to the secondary containment may be required by actions specified in the EOPs.

Per EOP basis, Submergence is the preferred method for cooling the core. The core is adequately cooled by Restore HPCS injection prior to submergence when it can be determined 2 Emergency Depressurization (EOP- that RPV water level is at or above the top 1, ALC-8). of the active fuel. All fuel nodes are then assumed to be covered with water and heat is removed by boiling heat transfer.

• • Per NUREG-1021, Appendix D, If an operator or the crew significantly deviates from or fails to follow procedures that affect the maintenance of basic safety functions, those actions may form the basis of a CT identified in the post-scenario review. OBDI 202 - IOLE Process Rev 1
