NUREG-1021, Revision 9, Supplement 1 ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Examination Outline Cross-reference: Level RO SRO Tier # 1 Group # 1 K/A # 295025 EA2.02 Importance Rating 4.2 (K&A Statement) EA2.02 - Ability to determine and/or interpret the following as they apply to HIGH REACTOR PRESSURE: Reactor Power Proposed Question: SRO 1 With the plant operating at 80% RTP IAW OP 0105, "Reactor Operations", power is lost to the Electro-Hydraulic Pressure Regulator (EPR).

Which ONE of the following describes the reactor power response and course of action taken to stabilize the plant?

Reactor Power will (1) . The correct course of action is to (2) . A. (1) decrease (2) enter ONLY OT 3115, "Reactor Pressure Transients". Verify the MPR takes control THEN place the EPR in CUTOUT B. (1) increase (2) enter OT 3110, "Positive Reactivity Insertion" AND OT 3115, "Reactor Pressure Transients". Verify the MPR takes control THEN place the EPR in CUTOUT

C. (1) decrease (2) enter ONLY OT 3115, "Reactor Pressure Transients". Place the EPR in CUTOUT and raise the MPR setpoint to the pre-transient pressure D. (1) increase (2) enter OT 3110, "Positive Reactivity Insertion" AND OT 3115, "Reactor Pressure Transients". Place the EPR in CUTOUT and raise the MPR setpoint to the pre- transient pressure Proposed Answer: B NUREG-1021, Revision 9, Supplement 1 ES-401 Sample Written Examination Form ES-401-5 Question WorksheetExplanation (Optional):

SRO-ONLY Question Validity [10CFR55.43(b)(5)]: 1. Question cannot be answered by knowing system operation, flowpath, logic, initiation. 2. Question cannot be answered by knowing the immediate operator actions. 3. Question cannot be answered by knowing EOP entry conditions

4. Question cannot be answered by knowing the purpose, overall sequence of events, or overall mitigation strategy of a procedure. 5. Question requires assessing plant conditions and then prescribing a plant procedure or section of a procedure to mitigate recover, or with which to proceed.

A. (INCORRECT): Power will increase requiring OT 3110 entry B. (CORRECT): With the plant at 80% RTP, the candidate must understand the EPR is in control at a particular demanded setpoint/stoke condition and the MPR stroke is approximately 10% lower and setpoint slightly higher. As the EPR stroke fails low, pressure will be controlled by the MPR once the strokes are approximately matched. The MPR will then control plant pressure higher than its original value. As pressure increases, the void fraction in the core decreases, resulting in a higher moderator to fuel ratio. This will result in positive reactivity being added and a subsequent rise in reactor power. Additionally, in accordance with the UFSAR, a pressure increase collapses the voids in the moderator, causing an insertion of positive reactivity. IAW ARS 7-G-2 and OT 3115: If pressure is rising, THEN verify the MPR takes control and place the EPR CUTOUT SWITCH on CRP 9-7 to CUTOUT. OT 3110 is entered to the positive reactivity insertion. This procedure references you directly to OT 3115. C. (INCORRECT): Power will increase requiring OT 3110 entry and MPR setpoint is lowered to its pre-transient pressure. D. (INCORRECT): The MPR setpoint is lowered to its pre-transient pressure.

A. (INCORRECT): Actual flow is greater than indicated flow. Also, the Discharge Bypass Valve should not have been closed and is NOT directed to be opened to warm up the idle loop IAW OT 3118. The Discharge Valve is re-opened. B. (INCORRECT): Actual flow is greater than indicated flow. The Discharge Valve should have been closed and is directed to be opened to warm up the idle loop IAW OT 3118, NOT OT 3117. C. (INCORRECT): The Discharge Bypass Valve should not have been closed and is NOT directed to be opened to warm up the idle loop IAW OT 3117. The Discharge Valve is re-opened. D. (CORRECT): Comprehension based on understanding plant initial conditions and the flow circuitry response as a result. Some single loop conditions (<5 mlb/hr or 14 kgpm drive flow in operating loop) result in positive flow through the idle jet pumps. If positive flow through the idle jet pumps occurs, actual core flow will be greater than the core flow indicated. IAW OT 3118 step 7a and 7b, IF desired to maintain temperatures of the isolated loop, THEN verify the pump discharge valve has been closed for at least five minutes and OPEN PUMP DISCHARGE RV-53A. The valve was closed in follow-up action #1.

Question requires detailed knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific sub-procedures or emergency contingency procedures.

Justification for K/A match: OT 3100 Reactor Scram directs level to be controlled using various systems. These systems include HPCI and RCIC. There is a statement to use these systems unless directed otherwise by the EOPs. This is the tie to using Caution 3 basis to a reactor scram (post scram level control).

A. (INCORRECT): Vortexing in the CST is a concern based on CST water level. The basis for operating HPCI/RCIC with Torus suction <140F does not deal with vortexing concerns and damage to the pump impeller. Operation of HPCI and RCIC at high suction temperatures is permitted under emergency conditions to address adequate core cooling concerns with the understanding that the equipment may fail under continued operations.

B. (INCORRECT): The basis for operating HPCI/RCIC with Torus suction <140F does not deal with vortexing concerns and damage to the pump impeller.

C. (INCORRECT): Operation of HPCI and RCIC at high suction temperatures is permitted under emergency conditions to address adequate core cooling concerns with the understanding that the equipment may fail under continued operations.

D. (CORRECT): In accordance with the HPCI and RCIC Design Basis Documents, operation <140°F ensures NPSH requirements are met in order to prevent HPCI/RCIC pump cavitation and erosion which can lead to degraded performance or complete loss of function. In accordance with OP 2120 and OP 2121 (HPCI/RCIC), operation >140°F is not permitted unless required by the EOPs. In accordance with the EOP Study Guide (Volume 4), this caution does not imply that they can't be run and that it may be necessary to operate the turbines to address adequate core cooling concerns.

(3) Question cannot be answered by knowing the TS Safety Limits or their bases.

(4) Question can be answered by applying sections 3 and/or 4 in accordance with rules of application requirements.

A. Incorrect- The indications provided support a loss of DC-1/24V ECCS Distribution Panel "A". LI-2-3-91B is fed from LT-2-3-73B which was lost as a result of losing power to DC-1. Additionally, the loss of one indicator requires action to be taken within 30 days (T.S. Table 3.2.6 Note 1).

B. Incorrect- The loss of one indicator requires action to be taken within 30 days (T.S. Table 3.2.6 Note 1). After realizing DC-1 has been lost, LI-2-3-91B is plausible due to the cross arrangement of the 24V ECCS electrical distribution.

C. Correct- The indications provided support a loss of DC-1/24V ECCS Distribution Panel "A". DC-1 provides normal control power to the "B" EDG. Therefore, LT 3-73A still remains (powered from DC-2). Referring to G-191267. Sheet 1, LT-2-3-73A feeds LI-2-3-91A. IAS T.S. Table 3.2.6, LI-2-3-91A is a post accident instrument. With one level instrument (LI-2-3-91A/B) unavailable for use, T.S. Table 3.2.6 (Note 1) states: Within 30 days following the loss of one indication, restore the inoperable channel to service or-D. Incorrect- The indications provided support a loss of DC-1/24V ECCS Distribution Panel "A". LI-2-3-91B is fed from LT-2-3-73B which was lost as a result of losing power to DC-1. After realizing DC-1 has been lost, LI-2-3-91B is plausible due to the cross arrangement of the 24V ECCS electrical distribution.

• Drywell Pressure is 5.5 psig and rising slowly

• RPV Level is 137" and steady. The lowest observed level post scram was 95".

• RPV Pressure is 870 psig and lowering slowly.

• OT 3122, "Loss of Normal Power", Immediate Actions are complete with NO other actions performed.

Five minutes after level control is established, annunciator 4-U-2 "RCIC STEAM LINE P HI" alarms. RCIC responds as designed. There are NO Steam Leak Detection alarms and temperatures in the steam tunnel and Reactor Building remain steady.

SRO-ONLY Question Validity [10CFR55.43(b)(5)]: 1. Question cannot be answered by knowing system operation, flowpath, logic, initiation. 2. Question cannot be answered by knowing the immediate operator actions. 3. Question cannot be answered by knowing EOP entry conditions

4. Question cannot be answered by knowing the purpose, overall sequence of events, or overall mitigation strategy of a procedure. 5. Question requires assessing plant conditions and then prescribing a plant procedure or section of a procedure to mitigate recover, or with which to proceed.

A. Correct - A high DW pressure signal exists coincident with an LNP, as a result the only injection system operating is HPCI. A Group VI isolation of RCIC occurs; however, RCIC did not initiate because RPV level never reached 82.5". With RPV water level steady at 137" with HPCI injection, the correct level band is 127-177" using Table "C" Preferred Injection Systems. HPCI is a Preferred Injection System.

B. Incorrect - Table "D" Alternate Injection Subsystems are not directed unless RPV water level can not be restored and maintained above 127" (RC/L-1). With RPV water level above 127" and HPCI injecting, Table "D" is incorrect. This is a plausible distractor based on: if the student believes that either the HPCI system is a Table "D" alternate injection subsystem or that other systems from Table "D" should be used.

C. Incorrect - The RPV water level band should remain 127-177" since HPCI is still available and the isolation of RCIC, which was not injecting, should have no affect on RPV water level. The water level band is expanded to +6-177" when water level can not be restored and maintained above 127". If the student believes RCIC was injecting and has now isolated, this is a plausible distractor.

D. Incorrect - The water level band is expanded to +6-177" when water level can not be restored and maintained above 127". If the student believes RCIC was injecting and has now isolated, this is a plausible distractor. This is a plausible distractor based on: if the student believes that either the HPCI system is a Table "D" alternate injection subsystem or that other systems from Table "D" should be used.

With the plant operating at 70% RTP, a Loss of Normal Power (LNP) occurs coincident with a Loss of Coolant Accident (LOCA).

Post scram plant conditions are as follows:

• The Reactor Building is NOT accessible due to high radiation levels.

• The "B" EDG failed to start due to a fault on the respective bus.

• Buses 8 and 9 are NOT cross tied.

• All other systems respond as designed.

• Drywell and Torus pressures are identical at 12.0 psig and rising quickly.

• Torus level is 11 feet and rising slowly.

Additionally, the control room receives the following:

• Annunciator 3-J-1, "RHR PUMP A TRIP"

• Annunciator 3-J-3, "RHR PUMP A/B OVLD"

• Report from the TBAO that ONLY the 51A and 51B targets on the "A" RHR pump breaker cubicle are dropped.

IAW OP 2142, "4KV Electrical System", under some circumstances the "A" RHR Pump can be restarted WITHOUT being cleared by the Maintenance Department if it tripped on (1) .

Proposed Answer: A NUREG-1021, Revision 9, Supplement 1 ES-401 Sample Written Examination Form ES-401-5 Question WorksheetExplanation (Optional): SRO-ONLY Question Validity [10CFR55.43(b)(5)]: 1. Question cannot be answered by knowing system operation, flowpath, logic, initiation. 2. Question cannot be answered by knowing the immediate operator actions. 3. Question cannot be answered by knowing EOP entry conditions

4. Question cannot be answered by knowing the purpose, overall sequence of events, or overall mitigation strategy of a procedure. 5. Question requires assessing plant conditions and then prescribing a plant procedure or section of a procedure to mitigate recover, or with which to proceed.

A. (CORRECT): The candidate must first understand the nature of the trip. In this case, it's a time delay overcurrent trip which is allowed to be re-started IAW OP 2142 Precaution # 15 if the pump is needed for an emergency condition. In this case, with Drywell and Torus pressures equal, there is a problem with containment. If this problem is not addressed, the PSP curve will be challenged. The options are to spray the torus using alternate systems or to restart the only available RHR pump (C and D are powered from Bus 3 which is not powered and B was tagged out for maintenance leaving A as the only available RHR pump). Because the RB is inaccessible, OE 3107 Appendix "S" cannot be performed (local operation of RHR-183, 184, 70A/B, 71A/B). Therefore the only other option is to restart the pump that tripped on time delay overcurrent in an effort to prevent exceeding the PSP curve limits.

B. (INCORRECT): The RB is inaccessible to perform OE 3107 Appendix S

C. (INCORRECT): OP 2142 Precaution #14 does not allow restarting a pump on instantaneous overcurrent unless cleared by the maintenance department.

D. (INCORRECT): The RB is inaccessible to perform OE 3107 Appendix S. Also, OP 2142 Precaution #14 does not allow restarting a pump on instantaneous overcurrent unless cleared by the maintenance department.

Question requires detailed knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific sub-procedures or emergency contingency procedures.

A. (INCORRECT): Power is lost to Group 1 logic and the Main Condenser is not available. B. (CORRECT): To prepare for the possibility of the MSIVs closing as water level is intentionally lowered, Appendix P is implemented to prevent an unintended loss of the main condenser. Preserving the Main Condenser as a heat sink significantly reduces the energy that must be absorbed by the Torus and prolongs the availability of the Condensate/Feedwater Systems. With a loss of Normal Power (LNP), power is lost to both RPS buses therefore the MSIVs go shut due to a loss of power to Group 1 logic. Additionally, the Main Condenser is not available as required by step ARC/OR-5. Once power is restored to Bus 1 and/or Bus 2, the CW System can be restored to make the Main Condenser available. The MSIVs should remain closed an cannot be re-opened. C. (INCORRECT): If the MSIVs could be re-opened, step ARC/OR-5 directs the use of Appendix P, not CC. D.

Two LPRMs bypassed would not result in an INOP trip because its value would be greater than 12 LPRMs D. - Correct - APRM "D" is associated with "B" RPS. Ten LPRMs are assigned to "D" APRM. With two LPRMs bypassed and all of the shared LPRMs from "A" RPS de-energized an INOP trip signal will be generated because there are <9 LPRMs available as indicated by annunciator 5-M-2. The INOP trip signal on "B" RPS and the shutdown of "A" RPS MG set should result in a full reactor scram. The failure of the AUTO "B" RPS scram signal to function resulted in a failure of the auto scram function which meets the criteria for EAL A-7-c. Since the OATC actions failed to move the control rods, the manual scram failure will meet the criteria for EAL S-7-csince power is >2%.

The reactor is at 45% RTP and EOP-2, "ATWS RPV Control", has been entered. Additionally:

• Both SLC Pumps are unavailable.

• The Field Support Supervisor is directed to implement alternate measures for Boron injection using OE 3107, "EOP/SAG Appendices".

SRO-ONLY Question Validity [10CFR55.43(b)(5)]: 1. Question cannot be answered by knowing system operation, flowpath, logic, initiation. 2. Question cannot be answered by knowing the immediate operator actions. 3. Question cannot be answered by knowing EOP entry conditions

4. Question cannot be answered by knowing the purpose, overall sequence of events, or overall mitigation strategy of a procedure. 5. Question requires assessing plant conditions and then prescribing a plant procedure or section of a procedure to mitigate recover, or with which to proceed. 6. Question requires detailed knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific sub-procedures or emergency contingency procedures.

A. (INCORRECT): Appendix K uses the CRD System to pump the contents of the SLC Tank to the RPV. This Appendix does NOT use drums of Boric Acid or Borax. Those are used by Appendix J. Also, this amount is equivalent to HSBW.

B. (INCORRECT): Under boron injection conditions where the SLC tank is available and a flowpath exists this would be the amount of Hot Shutdown Boron Weight- not CSBW. Additionally, the use of Appendix I requires at least one SLC pump be available.

C. (CORRECT): Under boron injection conditions where the SLC tank is available and a flowpath exists (Appendix K with CRD) then this is the Cold Shutdown Boron Weight. Appendix K will result in the SLC Tank being injected to the RPV. IAW EOP-2, once the tank level decreases by 30% (CSBW), then a cooldown can commence.

D. (INCORRECT): While 660 ppm represents the correct amount of boron injected into the RPV for CSBW conditions (OE 3107 Appendix J discussion), 2 samples are not required to prove the concentration for use of any boron injection procedure.

Additionally, the use of Appendix I requires at least one SLC pump be available.

SRO-ONLY Question Validity [10CFR55.43(b)(4)]: 1. Question requires analysis and interpretation of radiation readings as they pertain to selection of administrative, normal, abnormal, and emergency procedures.

A 20 minute exposure in a 10.5 R/hr field is an exposure of 3.5 R plus the current exposure of 380 mR equals a total exposure of 3.88 R.

IAW OP 3507 the following provides guidance:

• Section 4.1 "The Shift Manager is responsible for authorizing emergency dose guidelines depending on the emergency until relieved by the Emergency Plant Manager or Emergency Director."

• Section 5.2 "

IF tasks are being conducted within areas that show a significant increase in general area dose rates from normal plant radiological conditions, OR -- THEN the emergency dose control process will be used to control radiation exposure of personnel."

• Attachment 9.5 Emergency Dose Limits. Line 1 - Dose Limit 5 Rem (TEDE) for All Work Activities A. Incorrect - EN-RP-201 is for normal planned exposures. The SM is not the approving authority for this exposure.

B. Incorrect - This is the correct answer for normal planned exposures and the GMPO is the approving authority since the total exposure is between 3 - 4 R.

C. Correct - OP 3507 Emergency Radiation Exposure Control provides guidance on exposure limits during an emergency. During an emergency condition, the Plant Emergency Director (PED) authorizes the exposure limits. Since the EOF, TSC, and OSC are not manned, the SM is the PED. An exposure limit of 5 R TEDE is authorized IAW Attachment 9.5 of OP 3507.

Proposed Question: SRO 22 A plant startup is in progress IAW OP 0105, "Reactor Operation" with the turbine online. The reactor is at 20% RTP with annunciator 5-K-8, "STOP/CTRL VLV FAST CLOSURE BYP", illuminated.

Additionally, Annunciator 7-F-2, "TURB Excessive Vibration" alarms in the control room.

The ERFIS screen for "Turbine Bearing Performance" indicates the following:

• Bearings 1X, 1Y and 8X are alarming with a slowly rising trend in all three values.

• All other bearing temperatures and trends are stable.

Failure to take operator action in a timely manner will result in:

(1) Which ONE of the following plant responses? (2) What required actions to be taken?

A. (1) Bearings 1X and 1Y reach the trip setpoint causing MTS-1 to trip resulting in a turbine trip. (2) Enter ONLY ON 3154, "Load Reject". Verify 1T ACB, 81-1T ACB and T-1 MOD open. B. (1) Bearings 1X and 8X reach the trip setpoint causing MTS-1 to trip resulting in a turbine trip. (2) Enter ONLY ON 3154, "Load Reject". Verify 1T ACB, 81-1T ACB and T-1 MOD open. C. (1) Bearings 1X and 1Y reach the trip setpoint causing MTS-1 to trip resulting in a turbine trip. (2) Enter OT 3100, "Reactor Scram" AND ON 3154, "Load Reject". Verify house loads have transferred to the Startup Transformers.

D. (1) Bearings 1X and 8X reach the trip setpoint causing MTS-1 to trip resulting in a turbine trip. (2) Enter OT 3100, "Reactor Scram" AND ON 3154, "Load Reject". Verify house loads have transferred to the Startup Transformers.

NUREG-1021, Revision 9, Supplement 1 ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Proposed Answer: A Explanation (Optional):

SRO-ONLY Question Validity [10CFR55.43(b)(5)]: 2. Question cannot be answered by knowing system operation, flowpath, logic, initiation. 3. Question cannot be answered by knowing the immediate operator actions.

4. Question cannot be answered by knowing EOP entry conditions

5. Question cannot be answered by knowing the purpose, overall sequence of events, or overall mitigation strategy of a procedure. 6. Question requires assessing plant conditions and then prescribing a plant procedure or section of a procedure to mitigate recover, or with which to proceed.

A. (CORRECT): First the candidate needs to understand the logic. A turbine trip will occur if both axes on the same bearing reach the trip setpoint. Then the candidate must integrate the fact that power is <25% RTP, therefore annunciator 5-K-8 is lit (bypass of the auto scram on a turbine trip). Since a scram will not occur, OT 3100 is not entered. ON 3154 is entered based on ARS 7-F-2. B. (INCORRECT): The same axis for two different bearings will not result in a turbine trip. C. (INCORRECT): With power <25% RTP, an automatic scram will not occur. Also, there is nothing in the stem that suggests a manual scram is required. Therefore entry into OT 3100 and verification of house load transfer is not applicable. D. (INCORRECT): The same axis for two different bearings will not result in a turbine trip. Also, with power <25% RTP, an automatic scram will not occur. Also, there is nothing in the stem that suggests a manual scram is required. Therefore entry into OT 3100 and verification of house load transfer is not applicable.

A. Incorrect - With EDG room temperature <50F, the associated EDG should be declared INOPERABLE. Risk Management - availability will be assessed using AP 0172. When RCS pressure is 100 psig, the transition from AP-0172 - Online to AP-0173 - Outage Risk is performed. At 800 psig, AP 0172 should still be used to assess availability.

B. Incorrect - AP 0173 is a plausible distractor since the plant is shutdown, while the outage period has begun by output breaker status, risk management transitions to AP-0173 has not been met with RCS pressure greater than 100 psig.

C. Correct - "A" EDG is INOPERABLE with room temperature <50F and AP 0172 will assess the availability of "A" EDG

Proposed Question: SRO 24 A plant startup is in progress IAW OP 0105, "Reactor Operations". Reactor Power is being held at ~22%. Chemistry has taken reactor coolant samples IAW OP 4612, "Reactor Water System Sampling and Treatment". The following results were given to the Control Room Supervisor for review:

• Conductivity is 2.8 mho/cm

• Chloride ion concentration is 0.15 ppm

• I-131 dose equivalent is 1.8 Ci/gm. (This is the first I-131 sample)

Which ONE of the following actions is required based on these coolant chemistry results?

A. The startup shall continue IAW OP 0105 since all given chemistry samples are satisfactory.

Proposed Answer: B NUREG-1021, Revision 9, Supplement 1 ES-401 Sample Written Examination Form ES-401-5 Question WorksheetExplanation (Optional):

SRO-ONLY Question Validity [10CFR55.43(b)(2)]: (1) Question cannot be answered by knowing 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> TS/TRM action (2) Question cannot be answered by knowing the LCO/TRM information listed above the line. (3) Question cannot be answered by knowing the TS Safety Limits or their bases. (4) Question can be answered by applying sections 3 and/or 4 in accordance with rules of application requirements.

A. (INCORRECT): The candidate may believe these results are sat based on thinking the Iodine limit is 4 Ci/gm (T.S. 3.6.B.1.c), Conductivity limit is 10 mho/cm (TRM 3.6.B.3), and chloride limit is 0.1 ppm (TRM 3.6.B.3). However, in this case, Radioiodine concentrations are UNSAT IAW OP 4612 Table 3 and TS limits. Samples are required every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to ensure 1.1 Ci/gm is not exceeded for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This action to continue a startup may not be conservative since a concentration >1.1 Ci/gm is indicative of failure of the cleanup demineralizer or gross activity in the gaseous effluents is near the limit which is indicative of a potential fuel failure. B. (CORRECT): T.S section 4.6.B.1.e C. (INCORRECT): Chlorides are not out of spec. Because steaming rate is greater than 100,000 lbm/hour, the chloride spec is now 0.5 ppm. If steaming rate was <100,000 lbm/hour, then chlorides would be out of spec. 22% power provides greater than 100,000 lbm/hour. D. (INCORRECT): This would be the case if either radiochemistry iodine concentration exceeded 1.1 Ci/gm for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or if concentration exceeded 4.0 Ci/gm at any time. 4.0 Ci/gm is the iodine spike limit. Exceeding this limit will not guarantee we will be within the 10CFR50.67 dose guidelines in the event of a postulated LOCA.

4. Question cannot be answered by knowing the purpose, overall sequence of events, or overall mitigation strategy of a procedure. 5. Question requires detailed knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps.

A. Incorrect - Appendix G CAN NOT be implemented because the CRD flow control valve fails closed rendering drive and cooling water pressures unavailable for control rod insertion.

B. Incorrect - Appendix G CAN NOT be implemented because the CRD flow control valve fails closed rendering drive and cooling water pressures unavailable for control rod insertion. There are notes in Appendix D, G, and BB providing this information. Nothing in the stem prevents Appendix H from being performed.

C. Incorrect - Appendix G CAN NOT be implemented because the CRD flow control valve fails closed rendering drive and cooling water pressures unavailable for control rod insertion.

D. Correct - Appendix H CAN be implemented because there is no affect on the ability to vent the overpiston area. Also, there is adequate RPV Pressure to insert control rods (>500#).
