KiA MATCH ANALYSIS Question asks which indication would be the earliest indication of gross failed fuel to the control room operators. Candidiate must pick the correct choice from the list. ANSWER I DISTRACTOR ANALYSIS A. Incorrect. Plausible candidate may pick this since some accidents result in high radiation on the plant vent. Since this is high range, it is least likely for radiation to appear first. While the Plant Vent Radiogas may see some activity, an RCS leak would be required for it to detect gross failed fuel. B. Incorrect. This is a method of obtaining specific activity but it will not be the earliest. Plausible candidate may choose this if not aware of function of letdown rad monitor. C. Correct. This is the function of this radiation monitor and failed fuel is listed as a cause in the annunciator response procedures. D. Incorrect. This is a method that requires an RCS sample and a calculation. While failed fuel could be detected by this method, it would not be the earliest. Plausible candidate could choose this if unaware of function of the letdown rad monitor.

QUESTIONS REPORT for HL-14 NRC SRO DRAFT Exam This question meets 10CFR55.43(b) criteria for item # 4 - Radiation hazards that may arise during normal, abnormal, and situations, including maintenance activites and various contamination conditions. The SS has to make a decision on whether to perform early isolatation of the radiation release to limit contamination. This question meets 10CFR55.43(b) criteria for item # 5 - Assessment of facility conditions and selections of procedures during normal, abnormal, and emergency conditions. Per Vogtle Rules of EOP Usage procedure 10020-C, isolation would not be allowed until a transition to 19030-C has occurred. This implies a selection or transition of procedures must take place before the isolation is allowed. ANSWER I DISTRACTOR ANALYSIS A. Incorrect. Plausible the candidate may confuse this with the isolation of AFW / feed flow to the S/G which should not occur until S/G level is > 10% NR. B. Incorrect. Plausible the candidate may choose this as it is method to shut down the TDAFW pump,however, it is an RNO action if the individual steam supply is not able to be closed. Early actions are not allowed per 10020-C, Vogtle's EOP Rules of Usage Procedure. C. Incorrect. Plausible the candidate may not feel there is enough information to identify the ruptured S/G, but with the given indications and the BOP requesting permission to isolate implies he has identified the SG that is ruptured. However, per our EOP Rules of Usage this action would not be allowed early and is the reason it cannot be perfomred. D. Correct.

Question meets 10CFR55.43(b) criteria item # 2 - Facility operating limits in Tech Specs and their bases. There is no bases for the Shift Mannin Admin requirements. Question also is SRO due to KA importance factor for this topic is only 2.3 for the RO level and 3.4 for the SRO level. Therefore, it is an SRO only topic. ANSWER I DISTRACTOR ANALYSIS A. Incorrect. You can only go below minimum staffing for an exepected absence of duty. In this instance, there would be time to hold shift personnel over to maintain the minimum staffing. Plausible the candidate could think it would be OK to allow the personnel to leave as long as the off duty person arrives within 2 hours or not think of minimun requirements pertaining to non-licensed personnel. B. Incorrect. Miminum for unexpected on duty person is limited to 2 hours. Would need a replacement within 2 hours. Plausible the candidate could think there is one shift to replace the persons since a lot of other admin requirements are within one shift. C. Correct. Could go below minimum due to unexpected absense but would be required to replace the personnel within 2 hours. D. Incorrect. There is a 2 hour time limit for unexpected absence of on duty personnel. Would have to hold someone over. Plausible the candidate would think it is OK to allow the person to leave since a replacement should arrive within 2 hours.

Question meets 10CFR55.43(b) criteria item # 5 - Assessment of facility conditions and selection of procedures during normal, abnormal, and emergency situations. ANSWER I DISTRACTOR ANALYSIS A. Correct. ACCW pumps would not be running on a simultaneous LOSP / SI as SI sequence prevails and locks out the pumps. Initial Operator Actions of E-O would have the RO notify the SS of the condition and request permission to start the ACCW pumps, if they can't be started, trip the RCPs. B. Incorrect. Plausible if the candidate does not realize E-O initial actions address restoring ACCW or recognize why the pumps are stopped. An ACCW pump should be started and the RCPs not tripped. C. Incorrect. Plausible that candidate may realize why the ACCW pumps are stopped but not realize E-O Initial Operator Actions addresses. Stopping RCPs to protect them is a logical choice on loss of ACCW and AOP could be run in parallel by another operator. Restart of RCPs when available is also directed in many EOPs. D. Incorrect. Plausible the candidate may not recognize why the pumps are stopped or that E-O Immediate Operator Actions will address the condition. It is plausible that E-O would address the situation later, other EOPs such as the LOCA procedure which is the most likely transition in this situation would address the loss of ACCW pumps.
