REPORT DETAILS

REACTOR SAFETY

Cornerstone: Mitigating Systems - Reactor Operator (RO) and Senior Reactor Operator

(SRO) Initial License Examination

.1 License Applications

a. Scope

The examiners reviewed all 14 license applications submitted by the licensee to ensure 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 examiner also audited six of the license applications in detail to confirm that they accurately reflected the subject applicant's qualifications. This audit focused on the applicant's 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 October 15, 2010, the licensee proctored the administration of the written examinations to all 14 applicants. The licensee staff graded the written examinations in parallel with the NRC, analyzed the results, and presented their analysis to the NRC on October 20, 2010.

The NRC examination team administered the various portions of the operating examination to all 14 applicants October 4-8,2010. The four applicants for reactor operator licenses participated in two to three dynamic simulator scenarios, in a control room and facilities walkthrough test consisting of 11 system tasks, and an administrative test consisting of four administrative tasks. The five applicants seeking an instant senior operator license participated in three 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 five applicants seeking an upgrade senior operator license participated in 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

All 14 applicants passed all parts of the operating test. For the written examinations, the reactor operator applicants' average score was 91.66 percent and ranged from 86.66 to 96.00 percent, the senior operator applicants' average score was 90.30 percent and ranged from 86.00 to 96.00 percent. The overall written examination average was 90.71 percent. The text of the examination questions, the licensee's examination analysis, and the licensee's post-examination comments may be accessed in the ADAMS system under the accession numbers noted in the attachment.

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. The licensee conducted this performance analysis for three questions that met these criteria and submitted the analysis to the chief examiner. This analysis concluded that all three of these questions were valid as written. There were no post written examination comments submitted by the licensee .
