CALVERT CLIFFS NUCLEAR POWER PLANT 2012 ~NRC INITIAL LICENSED OPERATOR EXAM JPM #: SIM-7

Appendix C Job Performance Measure Form ES-C-1 Worksheet Facility: Calvert Cliffs 1 & 2 Job Performance Measure No.: SIM-7 Task

Title:

Respond to Inadvertent Dilution During Reactor Startup Task Number: 202.005 KIA

Reference:

015 A3.03 (3.9, 3.9)

Method of testing:

Simulated Performance: D Actual Performance: [gj Classroom: D Simulator: [gj Plant: D Read to the examinee:

I will explain the initial conditions, which steps to simulate or discuss, and provide initiating cues. When you complete the task successfully, the objective for this job performance measure will be satisfied.

Initial Conditions:

1. A reactor startup is in progress on Unit-1, OP-2 at step 6.6.G.
2. Shutdown CEAs are fully withdrawn
3. Regulating group CEAs are being withdrawn per OP-2 (There has been no rod motion for several minutes)
4. RCS Boron Concentration after completion last CEA withdrawal was 1690 PPM
5. Neutron counts unexpectedly begin to rise (30 CPS over the last five minutes)
6. The "S/D MON HI" annunciator (1C05, window D-33) alarms
7. 11 Purification Ion Exchanger has been in service for three weeks
8. You are performing the duties of the Unit-1 CRO Initiating Cue:

The CRS directs you to respond to the reactivity excursion per the appropriate procedure. Are there any questions? You may begin.

Task Standard:

Terminates an Inadvertent Dilution During Reactor Startup and Restores Required Shutdown Margin

Appendix C Job Performance Measure Form ES-C-1 Worksheet Evaluation Criteria:

1. All critical steps completed (denoted by shading).
2. All sequential steps completed in order.
3. All time-critical steps completed within allotted time.
4. JPM completed within validated time. Completion time may exceed the validated time if satisfactory progress is being made.

Required Materials:

Procedures and manuals normally available in the control room General

References:

OP-2, Plant Startup From Hot Standby To Minimum Load AOP-lA, Inadvertent Boron Dilution Time critical task:

No Validation Time:

10 minutes Simulator Setup:

1. IC-8, with reactor subcritical, a startup in progress with only the shutdown CEAs withdrawn, and power in the CPS range.
2. Connect SDM and reset alarms.
3. Set up the 1/M trending plot, on the Plant Computer, using OI-50A.
4. Use System Lineup to change VCT concentration to 0. Modify the file to change the VCT concentration back to 897, but don't execute the file. It is not needed during the AOP to stop the dilution since the operator will fast borate. But changing the file back to 897 restores the simulator to its normal setup.
5. Run simulator until count rate begins to increase and a SDM alarm comes in, then freeze.
