.1 Initial Licensing Examinations

a. Examination Scope

The NRC examiners and members of the facility licensees staff used the guidance prescribed in NUREG 1021, Operator Licensing Examination Standards for Power Reactors, Revision 11, to develop, validate, administer, and grade the written examination and operating test. Members of the facility licensees staff developed the written examination and NRC examiners prepared the operating test. The NRC examiners validated the proposed examination during the week of March 15, 2021, with the assistance of members of the facility licensees staff. During the on-site validation week, the examiners audited more than 20 percent of the license applications for accuracy. The NRC examiners, with the assistance of members of the facility licensees staff, administered the operating test, consisting of job performance measures and dynamic simulator scenarios, during the period of April 19 through April 22, 2021.

The facility licensee administered the written examination on April 26, 2021.

b. Findings

(1) Written Examination The NRC examiners determined that the written examination, as proposed by the licensee, was within the range of acceptability expected for a proposed examination.

Less than 20 percent of the proposed examination questions were determined to be unsatisfactory, requiring significant modification or replacement.

During validation of the written examination, several questions were modified or replaced. All changes made to the proposed written examination were made in accordance with NUREG-1021, Operator Licensing Examination Standards for Power Reactors, and documented on Form ES-401-9, Written Examination Review Worksheet. Form ES-401-9, the written examination outlines, and both the proposed and final written examinations, will be available electronically in the NRC Public Document Room or from the Publicly Available Records component of NRCs Agencywide Documents Access and Management System (ADAMS) on May 14, 2023 (ADAMS Accession Numbers ML20136A313, ML20136A310, ML20136A312, and ML20136A316, respectively).

On May 14, 2021, the licensee submitted documentation noting that there were no post-examination comments for consideration by the NRC examiners when grading the written examination.

The NRC examiners graded the written examination on May 11, 2021, and conducted a review of each missed question to determine the accuracy and validity of the examination questions.

(2) Operating Test During the validation of the operating test, several Job Performance Measures were modified or replaced, and some modifications were made to the dynamic simulator scenarios. Changes made to the operating test portion of the examination, were documented on Form ES-301-7, Operating Test Comments. Form ES-301-7, the operating test outlines, and both the proposed and final as administered dynamic simulator scenarios and Job Performance Measures, will be available electronically in the NRC Public Document Room or from the Publicly Available Records component of NRC's ADAMS on May 14, 2023 (ADAMS Accession Numbers ML20136A313, ML20136A310, ML20136A312, and ML20136A316, respectively).

The NRC examiners completed operating test grading on May 20, 2021.

(3) Examination Results Three applicants at the Senior Reactor Operator level and three applicants at the Reactor Operator level were administered written examinations and operating tests. In addition, one Senior Reactor Operator applicant was administered only a written exam.

All seven applicants passed all portions of their examinations and were issued their respective operating licenses on May 20, 2021.

.2 Examination Security

a. Scope

The NRC examiners reviewed and observed the licensee's implementation of examination security requirements during the examination validation and administration to assure compliance with Title10 of the Code of Federal Regulations, Part 55.49, Integrity of Examinations and Tests. The examiners used the guidelines provided in NUREG 1021, Operator Licensing Examination Standards for Power Reactors, to determine acceptability of the licensees examination security activities.

b. Findings

None.

4OA6 Meetings

.1 Debrief

The chief examiner presented the examination team's preliminary observations and findings on April 23, 2021, to Mr. D. Thomas, Senior Manager of Training, and other members of the Dresden Nuclear Power Station Operations and Training Department staff.

The following documents observations made by the U.S. Nuclear Regulatory Commission

examination team during the initial operator license examination. These observations do

not constitute audit or inspection findings and are not, without further verification and review,

indicative of non-compliance with Title 10 of the Code of Federal Regulations, Part 55.45(b).

These observations do not affect U.S. Nuclear Regulatory Commission certification or approval

of the simulation facility other than to provide information which may be used in future

evaluations. No licensee action is required in response to these observations.

During the conduct of the simulator portion of the operating tests, the following items were

observed:
