- 2. Select safety functions and systems for each JPM as follows:
Refer to Section 1.9 of the applicable knowledge and abilities (K/A) catalog for the plant systems organized by safety function. For pressurized-water reactor operating tests, the primary and secondary systems listed under Safety Function 4, Heat Removal from Reactor Core, in Section 1.9 of the applicable K/A catalog, may be treated as separate safety functions (i.e., two systems, one primary and one secondary, may be selected from Safety Function 4). From the safety function groupings identified in the K/A catalog, select the appropriate number of plant systems by safety functions to be evaluated based on the applicants license level (see the table in step 1).
For RO/SRO-I applicants: Each of the control room system JPMs and, separately, each of the in-plant system JPMs must evaluate a different safety function, and the same system or evolution cannot be used to evaluate more than one safety function in each location. One of the control room system JPMs must be an engineered safety feature.
For SRO-U applicants: Evaluate SRO-U applicants on five different safety functions.
One of the control room system JPMs must be an engineered safety feature, and the same system or evolution cannot be used to evaluate more than one safety function.
- 3. Select a task for each JPM that supports, either directly or indirectly and in a meaningful way, the successful fulfillment of the associated safety function. Select the task from the applicable K/A catalog (K/As for plant systems or emergency and abnormal plant evolutions) or the facility licensees site-specific task list. If this task has an associated K/A, the K/A should have an importance rating of at least 2.5 in the RO column. K/As that have importance ratings of less than 2.5 may be used if justified based on plant priorities; inform the NRC chief examiner if selecting K/As with an importance rating less than 2.5.
The selected tasks must be different from the events and evolutions conducted during the simulator operating test and tasks tested on the written examination. A task that is similar to a simulator scenario event may be acceptable if the actions required to complete the task are significantly different from those required in response to the scenario event.
Apply the following specific task selection criteria:
75-day transmittal copy - May24, 2022 S1 Emergency Boration - Alternate Path (Bank JPM-257)
Examinee observes the Reactor has tripped and commences Standard Post Trip Actions in accordance with EOP 2525. The examinee will observe and report (2) CEAs have not inserted and perform steps to Emergency Borate in accordance with EOP 2541, Appendix 3. The alternate path occurs after all action steps are completed and a check that Charging flow is greater than 40 gpm is being performed. The examinee will observe Charging flow is less than 40 gpm and take Contingency Actions (alternate path) to start an additional Charging pump to achieve greater than 40 gpm Charging flow.
At least one of the tasks shall be related to a shutdown or low-power condition.
Four to six of the tasks for RO and SRO-I applicants shall require execution of alternative paths within the facility licensees operating procedures. Two to three of the tasks for SRO-U applicants shall require execution of alternative paths within the facility licensees operating procedures.

- 1. Determine the number of control room system and in-plant system job performance measures (JPMs) to develop using the following table:
License Level Control Room In-Plant Total Reactor Operator (RO) 8 3
11 Senior Reactor Operator-Instant (SRO-I) 7 3
10 Senior Reactor Operator-Upgrade (SRO-U) 2 or 3 3 or 2 5
- 2. Select safety functions and systems for each JPM as follows:
Refer to Section 1.9 of the applicable knowledge and abilities (K/A) catalog for the plant systems organized by safety function. For pressurized-water reactor operating tests, the primary and secondary systems listed under Safety Function 4, Heat Removal from Reactor Core, in Section 1.9 of the applicable K/A catalog, may be treated as separate safety functions (i.e., two systems, one primary and one secondary, may be selected from Safety Function 4). From the safety function groupings identified in the K/A catalog, select the appropriate number of plant systems by safety functions to be evaluated based on the applicants license level (see the table in step 1).
For RO/SRO-I applicants: Each of the control room system JPMs and, separately, each of the in-plant system JPMs must evaluate a different safety function, and the same system or evolution cannot be used to evaluate more than one safety function in each location. One of the control room system JPMs must be an engineered safety feature.
For SRO-U applicants: Evaluate SRO-U applicants on five different safety functions.
One of the control room system JPMs must be an engineered safety feature, and the same system or evolution cannot be used to evaluate more than one safety function.
- 3. Select a task for each JPM that supports, either directly or indirectly and in a meaningful way, the successful fulfillment of the associated safety function. Select the task from the applicable K/A catalog (K/As for plant systems or emergency and abnormal plant evolutions) or the facility licensees site-specific task list. If this task has an associated K/A, the K/A should have an importance rating of at least 2.5 in the RO column. K/As that have importance ratings of less than 2.5 may be used if justified based on plant priorities; inform the NRC chief examiner if selecting K/As with an importance rating less than 2.5.
The selected tasks must be different from the events and evolutions conducted during the simulator operating test and tasks tested on the written examination. A task that is similar to a simulator scenario event may be acceptable if the actions required to complete the task are significantly different from those required in response to the scenario event.
Apply the following specific task selection criteria:
75 -day transmittal copy - May 24, 2022 At least one of the tasks shall be related to a shutdown or low-power condition.
Four to six of the tasks for RO and SRO-I applicants shall require execution of alternative paths within the facility licensees operating procedures. Two to three of the tasks for SRO-U applicants shall require execution of alternative paths within the facility licensees operating procedures.
At least one alternate path JPM must be new or modified from the bank.
At least one of the tasks conducted in the plant shall evaluate the applicants ability to implement actions required during an emergency or abnormal condition.
At least one of the tasks conducted in the plant shall require the applicant to enter the radiologically controlled area. This provides an excellent opportunity for the applicant to discuss or demonstrate radiation control administrative subjects.
If it is not possible to develop or locate a suitable task for a selected system, return to step 2 and select a different system.
- 4. For each JPM, specify the codes for type, source, and location:

Page 3 of 18 Scenario Summary:
The crew will take the shift with the unit at 100% power, steady state, with the B EDG OOS. The B SW Pump is running, supplying the B Service Water header.
Event 1: The ATC swaps Charging Pumps from P18C to P18A in Lead in accordance with OP 2304E, Charging Pumps; Section 4.2, Normal Charging Pump Operation.
Event 2: The B Service Water Pump trips. The crew enters AOP 2565, Loss of Service Water, and starts the C Service Water pump. The crew continues through the procedure. The US enters TS 3.7.4.1 for a Loss of a Service Water loop.
Event 3: The North bus de-energizes. There are no actions for the crew. The US enters TS 3.8.1.1.a for Loss of Off-Site lines.
Event 4: Condenser vacuum starts degrading, the crew enters AOP 2574, Loss of Condenser Vacuum.
Event 5: AOP 2574 directs the crew to AOP 2575, Rapid Downpower.
Event 6: Condenser Vacuum degrades to reactor trip criteria. The crew trips the plant.
Event 7: The Rx trip push buttons do not work, so the ATC opens the MG set feeder breakers to trip the reactor. The trip starts both the 10-minute Loss of Feedwater timer.
Event 8: On the trip, the A Diesel fails to start. The BOP starts the Diesel. After 10 seconds, the diesel output breaker trips open, at that point, the BOP trips the A EDG. The unit is now in a Station Blackout condition and the 60-minute SBO timer starts. The BOP starts the Terry Turbine. After completion of the Standard Post-Trip Actions, the crew diagnoses and enters EOP 2530, Station Blackout.
The scenario will end at the examiners discretion.

Page 3 of 20 Scenario Summary:
The crew will take the shift with the unit at 100% power, steady state, no equipment OOS (IC-21).
Event 1: The ATC places F14B in STBY and starts F14D in FAST in accordance with OP 2313A, Containment Recirculation and Cooling System.
Event 2: #1 Atmospheric Dump Valve (ADV) fails open due to controller output failing high. The BOP takes Immediate Operator Actions to take manual control of the ADV and closes it.
Event 3: RM-8241, CTMT High Range Rad Monitor, fails. The US refers to TSAS 3.3.3.1.b and Table3.3-6 then determines the plant meets the minimum channels requirement with RM-8240 still OPERABLE Event 4: A 90 gallon per day tube leak occurs in the #2 S/G. The crew enters AOP 2569, Steam Generator Tube Leak, and determines the plant is required to taken off line. The US enters TSAS 3.4.6.2.c due to > 75 gpd leakage through any one S/G Event 5: The crew commences a downpower iaw AOP 2575, Rapid Downpower Event 6: A S/G tube rupture occurs. The crew trips the unit and enters EOP 2525, Standard Post Trip Actions. The 60-minute clock for isolating #2 S/G starts here.
Event7: A LOCA occurs at the time of the trip. Multiple events are diagnosed and the crew transitions to EOP 2540, Functional Recovery. Containment Isolation Safety Function is determined not to be met. The crew enters EOP 2540E, Functional Recovery of Containment Isolation. The plant is cooled down and the #2 S/G is isolated Event 8: The A HPSI pump is degraded and the C HPSI pump does not start on the SIAS signal. The ATC takes action to start the C HPSI pump.
The scenario will end at the examiners discretion.

Page 5 of 20 Critical Tasks Elements Critical Task Statement Cooldown the RCS prior to isolating the faulted Steam Generator.
Initiating Cue EOP 2541, Appendix 12, SGTR Response; step 1. Commence Cooldown to TH Less Than 515 F Performance Feedback A cooldown of RCS temperatures, within Technical Specification limits (< 100 F/hour), should be observed. Note that the temperature change limits are for a continuous 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> period.
Success Path The plant cooldown is performed by operating either the Atmospheric Dump Valves or the Condenser Steam Dump valves.
Measurable Performance Standard The plant is cooled down to both loops THOT temperatures are less than 515 F prior to isolating the faulted Steam Generator.
Critical Task Statement Secure all RCPs within 10 minutes of losing NPSH Initiating Cue RCS Pressure drops below the operating limit of the Reactor Coolant Pumps Performance Feedback The RCPs are secured, causing Hot leg temperatures to increase as natural circulation heat removal is established. Steam dumps/ADVs throttle open to maintain TAVE/S/G pressure.
Success Path Opening the RCP breakers.
Measurable Performance Standard The operator is observed to commence a plant cooldown no later than one hour after an un-isolable LOCA occurs. A cooldown rate of greater than 40 F/hour shall be established and maintained.
Critical Task Statement Isolate the affected steam generator.
Initiating Cue EOP 2541, Appendix 12, SGTR Response; step 7. Isolate Most Affected S/G Performance Feedback The positioning of components is observable by lights, switches and other control indications. When isolated, the affected S/G pressure will stabilize since no more steam is being drawn off and the affected loops T will go to zero as the SG is no longer available as a heat sink.
Success Path The affected S/G is isolated by performing the component manipulations to establish the desired plant condition of the affected S/G being isolated from the outside environment.
Measurable Performance Standard The affected S/G is isolated within 60 minutes of the Tube Rupture.

5 of 19 Critical Task Elements Critical Task Statement Isolate Auxiliary feedwater to the affected S/G within 15 minutes of a MSI signal Initiating Cue EOP 2525, Standard Post Trip Actions, step 7. RCS Heat Removal, RNO step c.2 (S/G pressure < 572#
AND ESD is in progress).
Performance Feedback Affected S/G will boil dry once feedwater is isolated to it.
Success Path Isolating feed to a faulted S/G reduces the amount of energy released to the CTMYT atmosphere, keeping CTMT within design limits.
Measurable Performance Standard The operator places both OVERIDE/MAN/START/RESET switches in PULL TO LOCK and both Auxiliary Feedwater regulating valves, FW-43A&B, are closed.
Critical Task Statement Establish RCS pressure and temperature control to maintain the RCS less than 200 F subcooling.
Initiating Cue EOP 2525, Standard Post Trip Actions, step 7. RCS Heat Removal, RNO step c.3 (S/G boiled dry and CET temperature rising)
Performance Feedback Opening the ADV for the unaffected S/G after the affected S/G boils dry transfers the RCS Heat Removal function to the unaffected S/G. CET temperatures will stabilize, the RCS will not cooldown or heat up.
Success Path Setting the unaffected S/Gs ADVs automatic setpoint to the saturation pressure associated with the CET temperature will stabilize RCS temperature.
Measurable Performance Standard When the affected S/G boils dry, the operator reduces the unaffected S/Gs ADV automatic setpoint to approximately the saturation pressure of the CETs (at the point where the affected S/G boiled dry) using either the PPC SPDS screen or the steam tables.
