The question was psychometrically correct and correct as written. The students indicated that they were under a misconception 18 when answering this question, they considered the narrow range on the instrument itself and the smaller graduations on the scale to determine accuracy, not the effect of the change in temperature and flow. Following the review of the exam, the students that missed this question understood why they missed it and what the real answer is.

This question dealt with the response of the HPCI system on an automatic trip following a manual initiation. The question is psychometrically correct and as written has one correct answer. The students could not remember what actions other than the 22 stop valve closing would occur. This may be a weakness in the base HPCI knowledge of the students that missed this question. A follow-up reminder will be sent to the students concerning this concept.

This question dealt with actions that should be performed, given a set of conditions. The question is psychometrically correct and as written has one correct answer. The students could provide the reasons why each action should be done, but when presented 26 with a set of conditions could not recognize which way the correct action that must be done. This may be a weakness in the way they studied this material. A follow-up reminder will be sent to the students concerning this concept.

This question dealt with Precautions and Limitations from the Operating Procedures. The question is psychometrically correct and as written has one correct answer. The students indicated that they had not studied the Precautions and Limitations as deeply as 32 they should have and realized that, upon review of the exam that the reason was clearly stated in the procedure. This may be a weakness in the way they studied this material. A follow-up reminder will be sent to the students concerning this concept.

This question dealt with the Tech Spec maximum temperature for SLC. The question was challenged psychometrically and as written has the incorrect answer specified. Most of the students that missed this question were aware of the graph in Tech Specs and knew that the graph did not go above 100 deg. They just could not remember what the values was. The Procedure for SLC 33 and the USAR specifies a maximum temperature of 140 deg. The students that got this question correct indicated that they knew the value from the Precaution in the procedure. This may be a weakness in the way they studied this material. A follow-up reminder will be sent to the students concerning this concept. This question is being challenged in accordance with NUREG 1021, to change the answer from "C" to "B".

This question dealt with the affects that a loss of Rx Building Reliable Air would have on the ADS valves if an actuation would occur. The question is psychometrically correct and as written has one correct answer. The students that missed this question 39 stated that they confused the air supply with the Nitrogen supply to the ADS valves. This may be due to the way we re-enforce the failures to them. The instructors concentrated on re-enforcing the loss of N2, not air, because nothing happens when you lose air, if N2 is lined up. This should go as a lessons learned for the instructors in the way we present failures.

6/13/05 ILT 10-05 NRC Exam This question dealt with the definition of a symmetric rod pattern. The question is psychometrically correct and as written has one correct answer. The students that missed this question stated that they had not studied the definitions out of the procedures 54 concerning rod motion. This may be a weakness in the way they studied this material. A follow-up reminder will be sent to the students concerning this concept.

This question dealt with RHR system valve alignments that would prevent intersystem LOCAs. The question is psychometrically correct and as written has one correct answer. The students that missed this question stated that they picked choice "D" because 55 it sounded right. Many of the students remembered the reason way the 101 and 102 are never opened at the same time, because during an outage an operator drained water from one loop of RHR to the other drained loop by opening these valves.

This question dealt with the RHR system in Fuel Pool Cooling Assist and the affects a lowering flow would have on the ability to cool the fuel pool. The question is psychometrically challenged as written because the minimum flow valves are tagged closed 59 during this evolution. It however has only one correct answer. The students that missed this question stated that they picked choice "A" because they knew that the minimum flow valves were tagged closed and that was the only other answer that could be right.

This question dealt with cycle efficiency and the effect the loss of extraction steam would have on reactor power and hotwell temperatures after an hour. The question is psychometrically correct and as written has one correct answer. The students that missed this question stated that they forgot that the A5 Feedwater Heater did not have a dump valve back to the condenser and 60 therefore believed that raw steam would be rejected to the condenser, thus making the hotwell temperature rise. This may be a lack of fundamental knowledge on the steam cycle and as a result a follow-up reminder will be sent to the students concerning this concept.

This question dealt with LCO entry conditions. The question is psychometrically correct and as written has one correct answer.

68 Distractor "D" was chosen because the students knew that RCIC has a surveillance for testing the MO-30 but failed to realize that it was not a surveillance for the RCIC system. This concept will be discussed with the students before they go on watch.

This question dealt with the requirements for monitoring occupational dose. The question is psychometrically correct and as written has one correct answer. There is a CNS requirement to have everybody wear a DRD and TLD when entering the RCA and the 72 students considered that monitoring of occupational dose. They did not realize the difference between 10CFR20 requirements and CNS requirements. CNS is more restrictive and therefore they chose that answer.

This question dealt with the the requirement of an ALARA brief. The question is psychometrically correct and as written has one 73 correct answer. The students stated that they did not think that this concept would be asked on an NRC Exam. They wer told that all radiological requirements are required knowledge and they understand that now.

This question dealt with the technical basis for the operability of the torus to drywell vacuum breakers. The question is psychometrically correct and as written has one correct answer. The students remembered the old reason given in the BWR EPGs 82 concerning the upper region of the DWSIL graph, that was removed and the reason behind that removal elimiated the words implosion. THis was a case where the students remembered old material versus the new material that was pressented during class. They all understand that now.

This question dealt with the Tech Spec requirements to be in MODE 3 on a failure to do a surveillance on the RPS High Pressure 83 Scram sensors. The question is psychometrically correct and as written has one correct answer. The two students that missed this question stated that they made a math error.

This question dealt with the required procedure that is required to be entered on a total loss of off site power when one of the 90 diesels is tied to their bus for testing. The question is psychometrically challenged as written. THe students felt that there was no correct answer so they picked the best one of the choices provided.

This question dealt with the a non-spiral off-load that was in progress and the SRM requirements per Tech Specs. The question is psychometrically correct and as written has one correct answer. The two individuals that missed this question stated that they did 91 not full research the surveillance requirement and missed that the less than three count requirement did not apply. They now that now.

This question dealt with temporary alterations to the facility and the time limit requirement for 50.59 evaluation. The question is 95 psychometrically correct and as written has one correct answer. This concept was not studied by the students and they have been instructed on that requirement during the exam review.

This question dealt with the Emergency Director's authorization of emergency dose. The question is psychometrically correct and as written has one correct answer. The two individuals stated that they had forgotten the exact requirement, but know where to find 98 it, and just answered incorrectly. Emergency dose requirements were re-enforced with those two students again during exam review.
