c 5.0 SPECIAL CONSIDERATIONS 5.1 Gas decay tanks may only be released during certain weather conditions (see Section 3.0, Precautions and Limitations). Due to the unpredictability of the weather, Waste Gas releases may need to be suspended or terminated before the tank has emptied entirely.

5.2 Suspending a waste gas release until desirable conditions exist is acceptable, however once a release procedure is begun, it should be terminated within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

5.3 If unfavorable weather occurs prior to releasing any gas to the environment (up to Section 7.13) it is acceptable to terminate the release, detach the Effluent Release Permit from the old release procedure marking applicable steps N/A, and reattach the Effluent Release Permit to a new release procedure. If a release is terminated after Section 7 .13 has begun, a new gas decay tank sample and Effluent Release Permit should be generated before another release is attempted.

- A LOCA has occurred on Unit 1.

- Containment pressure is 0.1 psig and stable.

- RCS subcooling is 92°F and stable.

- Total feed flow to SGs is 250 gpm and stable.

- RCS pressure is 1840 psig and stable.

- Pressurizer level is 0% and stable.

- Auxiliary building radiation alarms are the ONLY radiation alarms occurring.

- Additional equipment failures result in the break NOT being isolable from the RCS.

2014 NRC INITIAL LICENSE WRITTEN EXAM SENIOR REACTOR OPERATOR 3-SPK EXPLANATION:

This question is linked to 10 CFR 55.43(b)(5) Assessment and selection of procedures. The question can NOT be answered by solely knowing "systems knowledge" OR by solely knowing immediate operator actions OR by solely knowing entry conditions for AOPs or plant parameters that require direct entry to MAJOR EOPs OR by solely knowing the purpose overall sequence of events or overall mitigative strategy of a procedure. The question requires assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed.

Justifications:

a. Correct. Since the LOCA is in the Auxiliary Building, transition is made directly to 1ECA-1.2 based on adverse radiation levels in the Auxiliary Building. The transition to 1ECA-1.1 is made because all RCS water is going to the Auxiliary Building instead of sump B in containment; therefore, loss of recirc capability.

b. Incorrect. Plausible as the SS will transition from 1E-0 to 1ECA-1.2; however, the unit will not be cooled down using ES-1.1.

c. Incorrect. Plausible if the examinee incorrectly believes SI termination criteria is met and incorrectly believes the unit will be cooled down using 1ES-1.1. SI termination criteria is not met because pressurizer level is below 7% and RCS pressure is below 2000 psig. During a normal small break LOCA (i.e. inside containment), the unit would be cooled down using 1ES-1.1.

d. Incorrect. Plausible as the crew would transition to 1ES-0.2 and the unit would be cooled down using 1C1.3; however, this procedure flow path would only be used in this situation if SI termination criteria was met. SI termination criteria is not met because pressurizer level is below 7% and RCS pressure is below 2000 psig.

Fuel Cladding RCS Containment A. POTENTIAL LOSS LOSS INTACT B. POTENTIAL LOSS INTACT INTACT C. INTACT LOSS INTACT D. INTACT INTACT POTENTIAL LOSS Page 43

2014 NRC INITIAL LICENSE WRITTEN EXAM SENIOR REACTOR OPERATOR 3-SPR EXPLANATION:

This question is linked to 10 CFR 55.43(b)(6) Procedures and limitations involved in alterations in core configuration. This question requires evaluating emergency classifications based on core conditions.

Justifications:

a. Correct. A potential loss of fuel cladding barrier is indicated by the Core Cooling CSF being orange and by RVLIS full range less than 40% with both RCPs stopped. A loss of RCS is indicated by subcooling being less than 35F (containment is adverse because pressure is greater than 5 psig). Containment is intact because pressure is less than 46 psig. Also both trains of depressurization equipment (CFCU &

CS) are operating.

b. Incorrect. Plausible as there is a potential loss of fuel cladding; however, the RCS is NOT intact.

c. Incorrect. Plausible as there is a loss of RCS; however, fuel cladding is NOT intact.

d. Incorrect. Plausible if examinee incorrectly believes RVLIS level is ok because it is green instead of red on the STAT screen and misses that Core Cooling is orange. Also, if examinee does not notice the RCS is at saturation indicating a LB LOCA condition. Also, if examinee incorrectly believes containment is potentially loss because containment pressure is above 23 psig; however, this will only cause containment to be potentially loss if there is less than one full train of depressurization equipment running.

According to the STAT screen in this case, both trains are operating.
