2018 JPM Sim-d — Initiate Bleed and Feed Using Reactor Head Vents

⚠️ DRAFT
JPM Sim-d — Initiate Bleed and Feed Using Reactor Head Vents Sim | RO/SRO | 002 A2.04 (4.3/4.6)
Location: Simulator
Time-Critical: No
Alternate Path: Yes
Estimated Time: 8 minutes

Initial Conditions:
- Unit 2 was manually tripped at 90% power due to elevated main turbine vibrations IAW S2.OP-AB.TL-0001.
- An inadvertent feedwater isolation actuation occurred resulting in the loss of all main feedwater.
- Loss of all AFW flow occurred when all AFW pumps tripped.
- The crew has entered 2-EOP-FRHS-1 due to valid RED Path on Heat Sink CFST based on all SG NR levels < 9% and AFW flow < 22E4 lbm/hr.
- Plant conditions have continued to deteriorate and three (3) steam generator Wide Range levels are now less than 32%.
- The CRS is implementing the CAS action to Initiate Bleed and Feed.

Initiating Cue:
- You are the Reactor Operator.
- The CRS has directed you to Initiate Bleed and Feed starting at Step 21 IAW 2-EOP-FRHS-1, Response to Loss of Secondary Heat Sink.
- Your evaluator will respond to all alarms not related to your task.
Task Standard:
OPENS 2RC40 thru 2RC43 Reactor Head Vents IAW 2-EOP-FRHS-1.
▶ Show Critical Steps & Key Actions
Step Critical Element Standard
21 Read CAUTION: Steps 24 thru 29 must be performed quickly and without interruption Operator reads the Caution and continues.
21 STOP ALL RCPs Verifies all RCPs are already stopped (per Step 7 of FRHS-1).
22 * Initiate SI on both trains Inserts key and turns switch clockwise until SI Operate bezel illuminates and SI Reset bezel extinguishes. Only needs to initiate SI on one train.
23 Verify SI valves in Safeguards Position YES — checks all SI valve bezels on 2RP4 are illuminated.
23.1 Verify charging pumps running and BIT flow established Both charging pumps running (START bezels illuminated red). BIT flow established (~150-160 gpm on charging flowmeter).
23.2 Verify SI pumps running and Table C valves open Both SI pumps running (START PBs illuminated red). All Table C valves OPEN for both running SI pumps.
24 * Open both PZR PORV stop valves (2PR6 and 2PR7) Verifies both PZR PORV stop valves are OPEN (2PR6 and 2PR7 OPEN bezels illuminated).
24 * Open both PZR PORVs — 2PR2 fails to open (alternate path) ALTERNATE PATH: Places both PZR PORVs in Manual and depresses OPEN PBs for 2PR1 and 2PR2. Reports that 2PR2 will NOT OPEN. PORVs may be cycling — applicant must determine both PORVs are required fully open in Manual and not credit auto operation.
24.1 Verify both PZR PORV stop valves still open YES — 2PR6 and 2PR7 OPEN bezels still illuminated.
25 * Open Reactor Head Vent valves 2RC40 thru 2RC43 using keys at 2RP2 backpanel At 2RP2 backpanel, obtains four keys, inserts key into each keyswitch one at a time, and turns clockwise until OPEN bezel illuminates for 2RC40 through 2RC43.
Key Decision Point:
The discriminating step is Step 24 — the applicant must recognize that 2PR2 PORV fails to open in Manual and then transition to the alternate bleed path: opening the Reactor Head Vent valves 2RC40 through 2RC43 using key-locked switches on the 2RP2 backpanel. This is the same alternate path tested in the 2019 and 2023 Sim-d JPMs. The applicant must also correctly perform the rapid bleed and feed sequence without interruption (Steps 24-29), including manually initiating SI, verifying ECCS flow, and opening PORVs before identifying the need for reactor head vents.
