Appendix D Required Operator Actions Form ES-D-2 Op-Test No.: 1 Scenario No.: 4 Event No.: 8 Rev.: 0 Event
Description:
(Automatic Parameter Cue) EFIC will actuate from the HPI signal. The operator will recognize excessive EFW flow to the A OTSG through EFV-58. Rule 3 will be in effect and the operator will attempt to isolate flow by taking EFIC to manual and closing EFV-14 (block valve). The block valve will stroke partially in the closed direction and then the motor power fuse will blow. [MALF] The operator must secure EFP-3 (CT) to stop EFW flow to the OTSG.
Time Position Applicants Actions or Behavior
- Performs Rule 3, EFW/AFW Control
- Attempts to close EFV-58
- Determines that EFW flow is not controlled and depresses Manual Permissive on both channels

Appendix D Required Operator Actions Form ES-D-2 NOTES
- Letdown (LD) Cooler 1C is NOT normally aligned for service whenever Coolers 1A and 1B are both available. Normally LD Cooler 1C will have its SW outlet closed (SWV-691, RB entry required for opening) and its primary inlet (MUV-498) closed with electrical power removed.
- Restoration of Letdown Coolers can be classified as a R2 Reactivity Manipulation or a R3 Reactivity Related Activity based on the expected reactivity impact due to component boron concentration.
BEGIN R2/R3 REACTIVITY EVOLUTION IF it is desired to place A Letdown Cooler (MUHE-1A) in service, THEN PERFORM the following:
ENSURE OPEN the following:
- SWV-47, SW Inlet ...................................................................................................

NOTE: SW flow to Letdown (LD) Cooler 1C is set lower than LD Coolers 1A and 1B, therefore, letdown flow adjustments may be necessary to prevent high SW outlet temperatures.
IF either Letdown Cooler A or B can NOT be aligned for service, OR it is required to remove Letdown Cooler A or B from service, THEN PLACE Letdown Cooler C (MUHE-1C) in service as required:
