SUBJECT:

THREE MILE ISLAND NUCLEAR GENERATING STATION, UNIT 1 - INITIAL OPERATOR LICENSING EXAMINATION REPORT 05000289/2019301

Dear Mr. Hanson:

On June 17, 2019, the U.S. Nuclear Regulatory Commission (NRC) completed an examination at Three Mile Island Nuclear Generating Station, Unit 1. The enclosed examination report documents the examination results, which were discussed on July 29, 2019, with Messrs. Ed Callan, Joe Dulinger, Dave Lewis, Jeff Goldman, Lynn Florey, Ed Carreras, and other members of your staff.

The examination included the evaluation of four applicants for reactor operator licenses and two applicants for instant senior reactor operator licenses. 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 six of 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 25, 2019.

No findings were identified during this examination.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and the NRC Public Document Room in accordance with 10 CFR Part 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

SUMMARY

ER 05000289/2019301; June 10-13, 2019, June 17, 2019; Three Mile Island Nuclear

Generating Station, Unit 1; Initial Operator Licensing Examination Report.

Five NRC examiners evaluated the competency of four applicants for reactor operator licenses, and two applicants for instant senior reactor operator licenses at Three Mile Island Nuclear Generating Station, Unit 1. The facility licensee developed the examinations using NUREG-1021, Operator Licensing Examination Standards for Power Reactors, Revision 11.

The written examination was administered by the facility on June 17, 2019. NRC examiners administered the operating tests on June 10-13, 2019. The NRC examiners determined that all six of the applicants satisfied the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Part 55, and the appropriate licenses have been issued.

NRC-Identified and Self-Revealing Findings

No findings were identified.

Licensee-Identified Violations

None.

REPORT DETAILS

4OA5 Other Activities (Initial Operator License Examination)

.1 License Applications

a. Scope

The examiners reviewed all six 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 two 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.

b. Findings

No findings were identified.

.2 Operator Knowledge and Performance

a. Examination Scope

On June 17, 2019, the licensee proctored the administration of the written examinations to all six applicants. The licensee staff graded the written examinations, analyzed the results, and presented their analysis to the NRC on June 26, 2019.

The NRC examination team administered the various portions of the operating examination to all six applicants on June 10-13, 2019. The four applicants for reactor operator licenses participated in two or 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 two 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.

b. Findings

All six of the applicants passed all parts of the operating test. For the written examinations, the reactor operator applicants average score was 82.67 percent and ranged from 80 to 85.33 percent, and the senior operator applicants average score was 83.84 percent and ranged from 82.83 to 84.85 percent. 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 20 questions that met these criteria and submitted the analysis to the chief examiner. The NRC examiners completed the final grading of the written examination on July 26, 2019, and conducted a review of each missed question to determine the accuracy and validity of the examination questions.

The licensee submitted four post-examination comments on the written exam, reevaluated the expected technical specification action requirements for Event 4 in Simulator Scenario 2 and commented on aspects of a critical task in Scenario 2. The NRC reviewed the facilitys post-exam comment submittal package and generally agreed with the facility analysis. The NRC accepted multiple answers on three questions, deleted a question, and graded the operating test technical specification action statements in accordance with the revised Scenario 2. The text of the written examination questions, the operating test, and the licensees post-examination comments with the NRC resolutions may be accessed in the ADAMS system under the accession numbers noted in the Attachment 1. In accordance with current NRC policy the release of these documents will be delayed for 2 years.

.3 Initial Licensing Examination Development

a. Examination Scope

The facility licensee developed the examinations in accordance with NUREG-1021, Revision 11. All licensee facility training and operations staff involved in examination preparation and validation were listed on a security agreement.
