  • Note: 1.

2.

Ensure that at least two topics from every applicable KJA category are sampled within each tier of the RO and SRO-only outlines (i.e., except for one category in Tier 3 of the SRO-only outline, the "Tier Totals" in each KJA category shall not be less than two). (One Tier 3 Radiation Control KJA is allowed if the KJA is replaced by a K/A from another Tier 3 Category).

The point total for each group and tier in the proposed outline must match that specified in the table.

The final point total for each group and tier may deviate by +/-1 from that specified in the table based on NRC revisions. The final RO exam must total 75 points and the SRO-only exam must total 25 points.

3. Systems/evolutions within each group are identified on the associated outline; systems or evolutions that do not apply at the facility should be deleted and justified ; operationally important, site-specific systems that are not included on the outline should be added . Refer to Section D.1.b of ES-401 for guidance regarding the elimination of inappropriate KJA statements.
4. Select topics from as many systems and evolutions as possible; sample every system or evolution in the group before selecting a second topic for any system or evolution .
5. Absent a plant-specific priority, only those K/As having an importance rating (IR) of 2.5 or higher shall be selected.

Use the RO and SRO ratings for the RO and SRO-only portions, respectively.

6. Select SRO topics for Tiers 1 and 2 from the shaded systems and KJA categories.

7.* The generic (G) K/As in Tiers 1 and 2 shall be selected from Section 2 of the KJA Catalog , but the topics must be relevant to the applicable evolution or system. Refer to Section D.1.b of ES-401 for the applicable K/As.

8. On the following pages, enter the KJA numbers, a brief description of each topic, the topics ' importance ratings (IRs) for the applicable license level, and the point totals (#) for each system and category. Enter the group and tier totals for each category in the table above; if fuel handling equipment is sampled in other than Category A2 or G* on the SRO-only exam , enter it on the left side of Column A2 for Tier 2 , Group 2 (Note #1 does not apply) . Use duplicate pages for RO and SRO-only exams.
9. For Tier 3, select topics from Section 2 of the KJA catalog , and enter the KJA numbers, descriptions , I Rs ,

and point totals (#) on Form ES-401-3. Limit SRO selections to K/As that are linked to 10 CFR 55.43.

SCENARIO OVERVIEW Unit 1 is at 100% power, steady state, equilibrium xenon , BOL. Following completion of turnover, the Shift Manager requests that the BOP swap the OA & OB WS pumps per BwOP WS-1 and WS-3 in preparation for surveillance testing on Unit 2.

After completing shift turnover and relief, the BOP will swap the OA & OB WS pumps in accordance with BwOP WS-1 and WS-3. The OB WS pump will be started and the OA WS pump will be placed in standby.

After swapping WS pumps, a failure of power range N-44 lower detector will occur. The crew will take actions per hard card 1BwPR 1-10-RD & 1BwOA INST-1 "NUCLEAR INSTRUMENTATION MALFUNCTION" including defeating the channel functions. Technical Specifications 3.3.1 Conditions A, D & E apply.

After the Power Range failure is addressed, a failure of 1FT-522, 1B SG steam flow channel, will occur. The crew will take actions per hard card 1BwPR1-15-SG & 1 BwOA INST-2 "OPERATION WITH FAILED INSTRUMENT CHANNEL" and perform required actions. The crew will swap to an operable steam flow channel.

After completion of steam flow failure actions, letdown pressure controller, 1 PK-131 , output will fail low. The letdown pressure control valve , 1CV131 , will close and letdown pressure will rise lifting the letdown line relief valve . The ATC will take manual control of letdown pressure controller per hard card 1BwPR1-9-LD and restore letdown pressure. The crew may isolate letdown due to the lifting letdown relief valve. If letdown is isolated, it will be restored per BwOP CV-17.

After the 1 PK-131 controller failure is addressed, the 1A Containment Chilled Water pump will trip resulting in a trip of the 1A Containment Chiller. The crew will start the standby 1B Chilled Water pump and Chiller per BwOP VP-1 after receiving a report that the 1A Chilled Water pump motor appears damaged. Containment pressure and temperature will slowly rise as a result of the loss of Containment Cooling . The US should reference Tech Spec 3.6.4 and 3.6.5 and place a priority to start the standby Cnmt Chiller.

After the Containment Chilled Water malfunction has been addressed, a 1B Steam Generator Tube Leak will be initiated . The crew will implement 1BwOA SEC-8 "STEAM GENERATOR TUBE LEAK." The crew should determine from the estimated leak size that a fast ramp to remove the unit from power is required and make preparations to ramp the unit off line using 1BwGP 100-4, POWER DESCENSION or 1BwOA PWR-1 "POWER REDUCTION." Technical Specifications 3.4.13 Condition B applies.

After the SGTL has been addressed and the crew has ramped the unit sufficiently for a reactivity manipulation, the 1B SGTL will degrade to a 550 gpm Steam Generator Tube Rupture .

The crew will implement 1BwEP-0 "REACTOR TRIP OR SAFETY INJECTION." The crew will transition to 1BwEP-3 "SGTR."

The scenario is complete when the crew has terminated high head injection and established normal charging flow in 1BwEP-3.

Critical Tasks

1. Identify the 1B SG as the ruptured SG and isolate prior to a transition to 1BwCA-3.1 is required .

SCENARIO OVERVIEW Unit 1 is operating at 90% power, steady state, equilibrium xenon, BOL. Online risk is green. Following completion of turnover, coordinate with Unit 2 and lower total station reactive load by a total of 2 KV in accordance with BwOP MP-23. The 1B HD pump was taken out of service 3 days ago and will NOT be returned to service for an additional 5 days.

After completing shift turnover and relief, the BOP will lower Unit 1 reactive load 1 KV in accordance with BwOP MP-23.

After lowering reactive load, First Stage Turbine Impulse Pressure channel , 1PT-505, will fail low. After the crew diagnoses the failure of 1PT-505, the A TC will take manual control of rods after verifying turbine load stable. Initial ATC response is per hard card 1BwPR 1-10-RD, followed by entry into 1BwOA INST-2 "OPERATION WITH A FAILED INSTRUMENT CHANNEL, ATTACHMENT D." Tech Spec 3.3.1 Conditions A and P will be entered. The ATC will return rod control to automatic after verifying Tave and Tref are stable and within 1°F.

After the 1PT-505 failure is addressed, 1CV121, Charging Pump Flow Control Valve Controller 1FK-121, will fail to 0% demand. The 1CV121 valve will fully close and pressurizer level will drop. The crew will take actions to stabilize the plant by taking manual control of the 1FK-121 controller and restore charging flow.

Afterthe 1FK-121 failure has been addressed , 1C SG NR level transmitter, 1LT-539, will fail low.

1FW530, Feedwater Regulating Valve, will open and 1C SG level will rise. The BOP will take manual control of 1C SG level per hard card 1BwPR 1-15-SG and stabilize 1C SG level. 1BwOA INST-2 "OPERATION WITH A FAILED INSTRUMENT CHANNEL," ATTACHMENT E, will be entered. The BOP will restore 1C SG level control to automatic after 1C SG level is restored to normal and an operable 1C SG NR level controlling channel is selected. Tech Specs 3.3.1 Conditions A and E and 3.3.2 Conditions A and Dare applicable.

After the 1LT-539 failure has been addressed , 1A Heater Drain Pump will trip. 1BwOA SEC-1 "SECONDARY PUMP TRIP," ATTACHMENT C, will be entered. The BOP will initiate a turbine load reduction to 780 MW at 20 MW/minute. The ATC will borate the RCS as necessary during the load reduction.

As the crew is reducing load to address the 1A HD pump trip, a large steam break will occur on the 1C MS line. When containment pressure reaches 20 psig , Phase B actuates but the CS pumps do not start.

The crew should manually realign train B CS valves which will start the 1B CS pump. Operators should transition to 1BwEP-2 "FAULTED STEAM GENERATOR ISOLATION" and recognize that the MSIVs have failed to close and that an uncontrolled depressurization of all SGs is in progress. The crew will transition to 1BwCA-2.1 "UNCONTROLLED DEPRESSURIZATION OF ALL STEAM GENERATORS" where they will throttle AF flow to the SGs. Entry into 1BwFR-H.1 "RESPONSE TO LOSS OF SECONDARY HEAT SINK" will be required when the crew throttles AF flow to 45 gpm per SG; however, a note in 1BwFR-H.1 directs that the procedure should NOT be performed . The crew will continue in 1BwCA-2.1 .

Completion criteria is stopping the RH pumps in 1BwCA-2.1.

Critical Tasks

1. Manually actuate one train of containment spray prior to transition out of 1BwEP-0.

SCENARIO OVERVIEW Unit 1 is operating at 100% power, steady state, equilibrium xenon , SOL. 1B CW pump is OOS for motor inspection. Automatic Rod Control is failed (rod speed programmer failure). Rods are in MANUAL. IMO troubleshooting will commence in 3-4 hours. Following completion of turnover, the crew is to perform 1BwOS EH-M1 "UNIT 1 PUMP OPERABILITY SURVEILLANCE, " using the preferred method of depressing and holding the MCB pushbutton. An Equipment Operator has been briefed and is standing by at the Unit 1 EH skid .

After completing shift turnover and relief, the BOP will perform 1BwOS EH-M1 "UNIT 1 PUMP OPERABILITY SURVEILLANCE. "

After completing the surveillance, feed flow channel , 1FT-530, will fail low resulting in rising feed flow and opening of 1FW530, 1C SIG Feed Reg Valve, to match feed flow with steam flow. The BOP will diagnose the failure and take manual control of 1FW530 to restore 1C SG level. The US will enter 1BwOA INST-2 "OPERATION WITH A FAILED INSTRUMENT CHANNEL -ATTACHMENT G." The crew will take actions per hard card 1BwPR1-15-SG & 1BwOA INST-2 and perform appropriate actions. The crew will swap to an operable feed flow channel.

After addressing the failed feed flow channel, the 1A CV pump shaft shear will occur. The crew will implement 1BwOA PRl-15 "LOSS OF NORMAL CHARGING. " The crew will start the 18 CV pump to restore normal charging . Technical Specifications 3.5.2 Condition A and TRM 3.1.d Condition A apply.

After the charging pump failure is addressed, the 1A Essential Service Water (SX) pump will trip due to an overcurrent condition. The crew will take actions per hard card 1BwPR 1-2-A 1 to start the 1B SX pump. The crew MAY enter 1BwOA PRl-8, ESSENTIAL SERVICE WATER MALFUNCTION . Tech Specs 3.7.8 Condition A applies. The 1A SX pump will remain unavailable for the rest of the scenario .

After the 1A SX pump trip is addressed, the master pressurizer pressure controller output will fail to 2195 psig (0% demand) in automatic. The RO will identify the failure and take manual control to restore pressurizer pressure .

After the master pressurizer pressure controller failure has been addressed, an air leak will develop in the main condenser. The crew will enter 1BwOA SEC-3 "LOSS OF CONDENSER VACUUM ," dispatch operators to locate the leak and contact Engineering to evaluate the leakage. With the 1B CW pump OOS; the crew will be required to commence a ramp down of Unit 1 to stabilize the loss of vacuum.

During the ramp, the boric acid transfer pump will trip during the first boration. The common boric acid pump will not be available and the ATC will have to continue the ramp with rods only.

After a sufficient reactivity manipulation has occurred, an inadvertent FWI occurs. When the crew manually trips the reactor, a feed line break on the 1C SG inside containment will occur. The 1B CV pump trips when the reactor trips . The crew will enter 1BwEP-0 to stabilize the plant and SI will actuate. The 1B SI pump fails to auto start and must be manually started . The 1A and 1B AF pumps will not start resulting in a transition to 1BwFR-H.1 "RESPONSE TO LOSS OF SECONDARY HEAT SINK" at step 15of1BwEP-O. Bleed and feed will be required due to NO CV pumps running.

Completion criteria is establishing bleed and feed during the loss of heat sink.

SCENARIO OVERVIEW Unit 1 is at 53% power, steady state, equilibrium xenon , MOL. Online risk is green. Following completion of turnover, the crew will perform 1BwOSR 3.7.4.1 "MAIN STEAM SYSTEM ISOLATION 1MS018A/B/C/D VALVE TRAVEL AND INDICATION 18 MONTH SURVEILLANCE. " Once the surveillance is complete , the SM has directed ramping Unit 1 to 938 MW at 3 MW/min .

After completing shift turnover and relief, the BOP performs 1BwOSR 3. 7.4.1 . The 1B SG PORV, 1MS018B, will fail the test due to a broken hydraulic line when the valve is stroked open. The Unit Supervisor will enter Tech Spec 3.7.4 Condition A and Tech Spec 3.6.3 Condition C. 1MS019B will remain closed to comply with TS 3.6.3 Condition C. 1MS018B will remain unavailable for the remainder of the scenario. The crew should inform the SM following the 1MS018B failure.

After the 1MS0188 failure has been addressed, the crew will commence a ramp to 938 MW at 3 MW/min.

After a measurable change in power, 1PK-455C, Pressurizer Spray Valve controller, will fail to 100%

demand position. 1RY455C will fail full open and pressurizer pressure will drop. The ATC will take manual control of 1PK-455C per hard card 1BwPR 1-12-RY and lower demand to close the pressurizer spray valve .

Tech Spec 3.4.1 Condition A will apply if pressurizer pressure drops below 2209 psig.

After the 1PK-455C failure has been addressed, the controlling PZR level channel , 1LT-459 , will fail low.

The crew will implement 1BwOA INST-2 and take actions to restore PZR level control and stabilize plant conditions. Technical Specification 3.3.1 Conditions A and K apply (Tech Spec 3.3.3 and 3.3.4 for Accident Monitoring and Remote Shutdown Panel minimum channel requirements are still met).

After the failed PZR level channel has been addressed, 1FK-520, Feed Reg Valve 1FW520 Controller, will fail to 100% demand. 1FW520, 1B FRV, will fully open and 1B SG level will rise. The crew will take actions per hard card 1BwPR 1-15-SG to stabilize the plant by taking manual control of the 1B FRV controller.

After the 1FK-520 failure is addressed, Heater Drain Tank (HOT) Level Controller, 1LK-HD009A, will fail to 0% demand . The 1HD046A/B valves will throttle close and HOT level will rise. The BOP will take actions to stabilize the plant by taking manual control of the 1LK-HD009A controller.

After the HOT Level Controller failure is addressed, the 1B MSIV fails closed causing three SG safety valves on the 1B SG to stick open resulting in a faulted SG. SG pressure will drop and a manual reactor trip will be required. The crew will implement 1BwEP-0 "REACTOR TRIP OR SAFETY INJECTION." When safety injection is actuated , the 1A CV pump will trip. The 1B CV pump must be manually started to establish high head ECCS flow. After determining 1B SG secondary pressure boundary is not intact, the crew will transition to 1BwEP-2 "FAULTED STEAM GENERATOR ISOLATION." When 1B SG pressure drops to 600 psig , a SGTR will occur on the 1B SG , causing a faulted/ruptured SG. The crew will complete isolation of 1B SG and transition to 1BwEP-3 "STEAM GENERATOR TUBE RUPTURE" based on secondary radiation trends on the 1B SG. In addition, the crew will recognize 1B SG pressure does not drop to zero and lowering pressurizer level/pressure will indicate a SGTR (alternate indications) . After determining the ruptured SG pressure is less than 320 psig, the crew will transition 1BwCA-3.1 "SGTR WITH LOSS OF REACTOR COOLANT-SUBCOOLED RECOVERY DESIRED. "

Completion criteria is completion of step 8 to stop the RH pumps in 1BwCA-3.1.
