WBN Nuclear Instrumentation Malfunctions 1-AOI-4 Unit 1 Rev. 0000 4.0 DISCUSSION 4.1 Source Range Failure SRM channels N131 & N132 are blocked manually above P-6. SRM channel indications are automatically removed above P-10. SRM channel failure may be evidenced by various alarms caused by loss of supply voltage, or the channel indicating high, low, and/or erratic. If one SRM channel fails high, Rx will trip at 105 cps unless the SRM trip is blocked. Audio count rate is required in Cntmt and in the Control Room when refueling operations are being conducted, and should be operating in the Control Room at all times when the source range channels are in service.
4.2 Intermediate Range Failure Malfunction of an IRM channel N135 or N136 may be evidenced by erratic or loss of indication, various alarms caused by loss of supply voltage, or by the channel indicating high, low, or erratic. One of two IRMs indicating greater than 25% power (and NOT blocked) will cause an Rx trip.

WBN Nuclear Instrumentation Malfunctions 1-AOI-4 Unit 1 Rev. 0000 4.3 Power Range Failure PRM channel malfunction may be evidenced by erratic or loss of indication, various alarms caused by loss of supply voltage, or the channel indicating high, low, or erratic. Greater than one PRM must fail high before Rx will trip on high flux.
DCS median signal selector will select the high-median value of the 4 PRM channels as NIS power to the S/G level setpoint for all four S/Gs. If two channels fail (one high and one low) the S/G level setpoint is defaulted to the Last Good Value (LGV).
The failure of one PRM to a value greater than 103% will result in an Auto/Manual Rod withdrawal block.
The rod control circuitry contains multiple lead/lag modules. Even with TAVG/TREF matched within 1 °F, rod movement could occur when the rods are returned to AUTO if rod control inputs change while rods were in MANUAL.
- Decay time for TAVG lead/lag modules is approximately 3 minutes.
- Decay time for TREF lead/lag modules and NIS lead/lag modules is approximately 5 minutes.
Allow at least 5 minutes between any change to rod control inputs (i.e., TAVG, TREF, or NIS) and placing rods in AUTO, this will help prevent undesired control rod movement.
Ensuring zero demand on the CERPI monitors in the main control room will also help prevent undesired control rod movement.

NRC EXAM 2013-302 READ TO APPLICANT DIRECTION TO APPLICANT:
I will explain the initial conditions, and state the task to be performed. All control room steps shall be performed for this JPM, including any required communications. I will provide initiating cues and reports on other actions when directed by you. Ensure you indicate to me when you understand your assigned task. To indicate that you have completed your assigned task return the cue sheet I provided you.
INITIAL CONDITIONS:
- 1. The Unit is at 100% RTP.
- 2. Auto Make-up from the Blender is out-of-service.
- 3. The STA has completed Appendix C, Calculation Of Boric Acid And Primary Water Integrator Setting For Manual Makeup, using REACTINW to raise VCT level from 35% to 40%.
INITIATING CUES:
The Unit Supervisor directs you to increase VCT level from 35% to 40%, using 1-SOI-62.02, Boron Concentration Control, Section 6.5, Manual Makeup, and the Appendix C/REACTINW data provided.
Notify the Unit Supervisor when the level increase has been completed.

WATTS BAR NUCLEAR PLANT JOB PERFORMANCE MEASURE D
NRC EXAM 2013-302 STEP/STANDARD SAT/UNSAT START TIME: _______
CAUTION When maintaining VCT level using Manual, level must be monitored closely to avoid charging pump suction auto swap over to RWST.
NOTES
- 1) Manual is used when auto makeup is unavailable or if desired due to special operating conditions. As RCS CB is changed during load follow, the Manual blended solution setpoints must be adjusted. Controls are on 1-M-6.
- 2) RCS CB may be slightly changed during blended makeup because of the inaccuracy in flow controller settings. When this occurs, small RCS temperature changes will be seen and control rod adjustments may be required to compensate for the temperature change.
- 3) If batching to the VCT, use several small batches, (rather than one large batch) to allow time to evaluate possible reactivity effects between batches. A maximum batch of 100 gallons at a time is allowed EXAMINER: Ensure that the applicant has been provided the REACTINW sheet for the level increase to 40%.
STEP 1: [1] PERFORM Appendix C, Calculation Of Boric Acid And ___ SAT Primary Water Integrator Setting For Manual Makeup OR ___ UNSAT USE Appendix B for Blending at greater than 2500 ppm.
STANDARD:
Applicant determines that Appendix C is complete based on INITIAL CONDITION 3 and utilizes the REACTINW printout provided.

[5.1] CHECK Red light is LIT. STEP STANDARD: ___ SAT Applicant locates 1-HS-62-140A, VCT MAKEUP CONTROL and rotates ___ UNSAT the handswitch to the right to the START position.
The applicant observes the GREEN light is DARK and the RED light is LIT.
Step is critical since this action is required to initiate manual makeup.
COMMENTS:
NOTE When blending to VCT through 1-FCV-62-128, Chemistry cannot get a representative sample of the blender outlet.
EXAMINER: When the applicant opens either 1-HS-62-128, MAKEUP TO VCT INLET or 1-HS-62-144, MAKEUP TO VCT OUTLET, the selected valve will fail open; 1-FCV 140D, BA TO BLENDER will fail OPEN; and 1-FC-62-139, BA TO BLENDER FCV-62-140 CONTROL will fail.
This combination of malfunctions will require the applicant to stop the boric acid pumps to terminate the boration.

WATTS BAR NUCLEAR PLANT JOB PERFORMANCE MEASURE I
NRC EXAM 2013-302 STEP/STANDARD SAT/UNSAT NOTE The next step will cause a pressure swing in the letdown header. The MCR operator and local operator should coordinate actions to minimize the pressure swings.
EXAMINER: The following step is a controlled iterative process. The applicant should throttle OPEN the bypass valve (1-BYV-62-672) a finite amount and then throttle CLOSED the isolation valve (1-ISV-62-673) an approximately equal amount. In doing this, the applicant will minimize the overall transient on the letdown subsystem.
If the applicant excessively throttles the bypass valve open (without isolating the normal letdown path an equivalent amount), then flashing in the letdown stream will occur.
If the applicant excessively throttles the isolation closed (without bypassing the normal path), then lifting of the letdown relief valve will occur (with diversion of letdown to the PRT).
