REPORT DETAILS
4OA5 Other Activities
.1 Initial Licensing Examinations
a. Examination Scope
The U.S. Nuclear Regulatory Commission (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. The written examination outlines were prepared by the NRC staff and were transmitted to the facility licensees staff. Members of the facility licensees staff prepared the operating test outlines and developed the written examination and operating test. The NRC examiners validated the proposed examination during the week of March 11, 2019, with the assistance of members of the facility licensees staff. During the on-site validation week, the examiners audited three 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 8, 2019, through April 17, 2019. The facility licensee administered the written examination on April 18, 2019.
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 and required modification or replacement.
During the validation of the written examination, several questions were modified or replaced. All changes made to the written examination were made in accordance with NUREG-1021, Operator Licensing Examination Standards for Power Reactors, and were documented on Form ES-401-9, Written Examination Review Worksheet. The Form ES-401-9, the written examination outlines (ES-401-1 and ES-401-3), 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 April 24, 2021 (ADAMS Accession Numbers ML17214A858, ML17214A855, ML17214A856, and ML17214A854, respectively).
On April 24, 2019, 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 April 26, 2019, and conducted a review of each missed question to determine the accuracy and validity of the examination questions.
- (2) Operating Test The NRC examiners determined that the operating test, as originally proposed by the licensee, was within the range of acceptability expected for a proposed examination.
Following the review and validation of the operating test, minor modifications were made to several job performance measures, and some minor modifications were made to the dynamic simulator scenarios. All changes made to the operating test were made in accordance with NUREG-1021, Operator Licensing Examination Standards for Power Reactors, and were documented on Form ES-301-7, Operating Test Review Worksheet. The Form ES-301-7, the operating test outlines (ES-301-1, ES-301-2, and ES-D-1s), and both the proposed and final operating tests, will be available electronically in the NRC Public Document Room or from the Publicly Available Records component of NRCs ADAMS on April 24, 2021, (ADAMS Accession Numbers ML17214A858, ML17214A855, ML17214A856, and ML17214A854, respectively).
The NRC examiners completed operating test grading on May 13, 2019.
- (3) Examination Results Nine applicants at the Senior Reactor Operator level and four applicants at the Reactor Operator level were administered written examinations and operating tests.
Thirteen applicants passed all portions of their examinations. Thirteen applicants were issued their respective operating licenses on May 13, 2019.
.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 Title 10 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
Two minor examination security-related issues were identified during operating test exam administration. In the first instance, an applicant noted a simulator procedure contained place-keeping markups that had not been sanitized following the previous scenario administration. Upon identifying the markups, the applicant immediately closed the procedure and reported the discrepancy to their NRC examiner of record. In the second instance, the simulator did not perform a complete reset following scenario administration and certain digital trend recorders maintained data from the previous crews scenario at the start of the next scenario. The trend recorder which could have provided actual exam information to the crew was located on a back panel and was manually reset by the training staff before any applicants could assess the information.
The NRC staff determined that in both instances, the examination security-related issues did not affect the fair and equitable administration of the examination. Nor did they require the replacement of examination material.
4OA6 Management Meetings
.1 Debrief
The chief examiner presented the examination team's preliminary observations and findings on April 18, 2019, to Mr. P. Karaba, Site Vice President, and other members of the Dresden Nuclear Power Station staff.
.2 Exit Meeting
The chief examiner conducted an exit meeting on May 9, 2019, with Mr. J. M. Condreay, Operations Training Manager, and other members of the Dresden Nuclear Power Station staff, by telephone. The chief examiner asked the licensee whether any of the material used to develop or administer the examination should be considered proprietary. No proprietary or sensitive information was identified during the examination or debrief/exit meetings.
