Rev 2

2017 ANO-1 NRC Exam Administered June 15, 2017 Page 1 of 3 RO Final Written Examination Analysis The threshold for determination of questions to be analyzed was a percentage of 50% incorrect responses. Due to only three applicants taking the exam this means that if two applicants missed a question, then it was analyzed.

1. 19 2/3 total applicants incorrect (66.7%)

Both chose A. The correct answer is B.

This question involves an approach to criticality where the operator is withdrawing rods when there is outward rod motion without a command and SUR is sustained at 2.5 DPM. The correct response in B is to trip the reactor and go to the Reactor Trip EOP. Distractor A contains only part of a sequence of commands (not all) which might stop outward rod motion without a command.

No change to the key was made. The question is technically correct as written, with no construction problems. We will be performing training needs analysis on this question.

1. 46 2/3 total applicants incorrect (66.7%)

Two chose C. The correct answer is B.

This question involves a Blackout condition and asks the minimum time the vital batteries are designed to power essential loads, and what loads are secured to extend battery capacity. The C distractor contains the correct loads which are secured but has the incorrect minimum time. No change to the key was made. The question is technically correct as written, with no construction problems. We will be performing training needs analysis on this question.

1. 57 3/3 total applicants incorrect (100.0%)

Two chose A, one chose D. The correct answer is C.

This question asks what feature in the ICS is specifically designed to respond to malfunctions which will have an effect on the nuclear fuel. The correct answer is the Delta Tc Controller whose only purpose is to minimize differences in cold leg temperatures between the loops and thus minimizes the effects those differences could have on quadrant tilt in the reactor core. No change to the key was made. The question is technically correct as written, with no construction problems. We will be performing training needs analysis on this question.

Rev 1

2017 ANO-1 NRC Exam Administered June 15, 2017 Page 2 of 3 (RO Final Written Examination Analysis continued)

1. 61 2/3 total applicants incorrect (66.7%)

Both chose D. The correct answer is C.

This question is about commencing a Reactor Building purge. This is an operation performed only during refueling outages and as such, the applicants may not have any experience with this equipment. However, this topic is part of their curriculum and is included in the K/A catalog. No change to the key was made. The question is technically correct as written, with no construction problems. We will be performing training needs analysis on this question.

1. 67 3/3 total applicants incorrect (100.0%)

Two chose D and one chose B. The correct answer is C.

This question is about the procedural requirements for manually seating a non-Q MOV inside the Reactor Building. The answer choices are in a 2x2 format and thus one must know two pieces of knowledge: 1) are danger tags used in the Reactor Building during heatup, and 2) do non-Q MOVs require the use of a torque wrench. Both incorrect answers chosen contain the use of danger tags.. No change to the key was made. The question is technically correct as written, with no construction problems. We will be performing training needs analysis on this question.

Rev 1

2017 ANO-1 NRC Exam Administered June 15, 2017 Page 3 of 3 SRO Final Written Examination Analysis Since there was only one SRO applicant the threshold for determination of questions to be analyzed was simply a miss of the question.

1. 95 1/1 total applicants missed (100.0%)

One chose A. The correct answer is D.

The question concerns two pieces of knowledge: 1) the maximum Tech Spec limit for dose equivalent I-131, and 2) which accident, besides a Main Steam Line Break, is this specification designed for. The answer chosen did not contain either correct piece of information. No change to the key was made.

The question is technically correct as written, with no construction problems. We will be performing training needs analysis on this question.
