Dear Mr. Hanson:

On December 12, 2019, the U.S. Nuclear Regulatory Commission (NRC) completed an examination at Limerick Generating Station, Units 1 and 2. The enclosed examination report documents the examination results, which were discussed on January 9, 2020, with Messrs.

Frank Sturniolo, Marty Bonifanti, and other members of your staff.

The examination included the evaluation of two applicants for reactor operator licenses, six applicants for instant senior reactor operator licenses, and one applicant for an upgrade senior reactor operator license. The written and operating examinations were developed using NUREG-1021, "Operator Licensing Examination Standards for Power Reactors," Revision 11.

The license examiners determined that all the applicants satisfied the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Part 55, and the appropriate licenses were issued on January 9, 2020.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs Agencywide Documents Access Management System (ADAMS). ADAMS is accessible from the NRC website http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

.1 License Applications

a. Scope

The examiners reviewed all nine 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 all nine of 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.

.2 Operator Knowledge and Performance

a. Examination Scope

On December 12, 2019, the licensee proctored the administration of the written examinations to all nine applicants. The licensee staff graded the written examinations, analyzed the results, and presented their analysis to the NRC on December 19, 2019.

The NRC examination team administered the various portions of the operating examination to all nine applicants on December 2-6, 2019. The two applicants for reactor operator licenses participated in three dynamic simulator scenarios, in a control room and facilities walkthrough test consisting of eleven system tasks, and an administrative test consisting of four administrative tasks. The six applicants seeking an instant senior reactor operator license participated in three dynamic simulator scenarios, a control room and facilities walkthrough test consisting of ten system tasks, and an administrative test consisting of five administrative tasks. The applicant for an upgrade senior reactor operator license participated in two dynamic simulator scenarios, a control room and facilities walkthrough test consisting of five system tasks, and an administrative test consisting of five administrative tasks.

b. Findings

All nine of the applicants passed all parts of the operating test. For the written examinations, the reactor operator applicants average score was 92.67 percent and ranged from 89.33 to 96.00 percent; the senior operator applicants average score was 93.14 percent and ranged from 90.00 to 97.00 percent. The overall written examination average was 93.03 percent. The text of the examination questions, the licensees examination analysis, and the licensees post-examination comments 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.

The NRC examiners completed the final grading of the written examination on December 20, 2019, and conducted a review of each missed question to determine the accuracy and validity of the examination questions.

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.
