REPORT DETAILS

4OA5 Other Activities Initial Operator License Examination

.1 License Applications

a. Scope

The examiners reviewed all license applications submitted by the licensee to ensure the applications reflected that each applicant satisfied relevant license eligibility requirements. The applications were submitted on NRC Form 398, Personal Qualification Statement, and NRC Form 396, Certification of Medical Examination by Facility Licensee. The examiners also audited the license applications in detail to confirm that they accurately reflected the subject applicants qualifications. This audit focused on the applicants experience and on-the-job training, including control manipulations that provided significant reactivity changes.

b. Findings

No findings were identified.

.2 Operator Knowledge and Performance

a. Examination Scope

On September 21, 2021, the licensee proctored the administration of the written examinations to all applicants. The licensee staff graded the written examinations, analyzed the results, and presented their analysis to the NRC on September 27, 2021.

The NRC examination team administered the various portions of the operating examination to all applicants on September 13-17, 2021. The applicants for reactor operator licenses participated in at least two dynamic simulator scenarios, a control room and facilities walkthrough test consisting of 11 system tasks, and an administrative test consisting of four administrative tasks. The applicants seeking an instant senior reactor operator license participated in at least two dynamic simulator scenarios, a control room and facilities walkthrough test consisting of 10 system tasks, and an administrative test consisting of five administrative tasks. The applicants seeking an upgrade senior reactor license participated in at least one dynamic simulator scenario, a control room and facilities walkthrough test consisting of five system tasks, and an administrative test consisting of five administrative tasks.

b. Findings

No findings were identified.

Twelve of the thirteen applicants passed the operating test and all applicants passed the written examination. For the written examinations, the reactor operator applicants average score was 91.8 percent and ranged from 85.3 to 96.0 percent, the senior operator applicants average score was 89.6 percent and ranged from 82.0 to 94.0 percent. The text of the examination questions may be accessed in the ADAMS system under the accession numbers noted in the Attachment. In accordance with current NRC policy, the release of this written examination in ADAMS to the public will be delayed for two years.

Chapter ES-403 and Form ES-403-1 of NUREG 1021 require the licensee to analyze the validity of any written examination questions that were missed by half or more of the applicants. Licensee training staff performed this analysis and forwarded it to the Chief Examiner. The licensee also submitted two emailed post-exam comments dated September 27, 2021, and October 6, 2021, both of which requested a change to the answer key for Crew Dynamic Scenario 1, Event 3 (Loss of VIAC 3). The NRC accepted one of the two emailed proposals (email dated October 6, 2021) and made the appropriate changes to the answer key. Details of those post exam comments and the associated NRC response may be accessed in the ADAMS system under the accession numbers noted in the Attachment.
