Nuclear Station; Operator License Examinations.

Nuclear Regulatory Commission (NRC) examiners conducted an initial examination in accordance with the guidelines in Revision 11, of NUREG-1021, "Operator Licensing Examination Standards for Power Reactors." This examination implemented the operator licensing requirements identified in 10 CFR §55.41, §55.43, and §55.45, as applicable.

The NRC developed the written examination outline. Members of the Virgil C. Summer Nuclear Station staff developed both the operating tests and the written examination. The initial operating test submittal met the quality guidelines contained in NUREG-1021.

The NRC administered the operating tests during the period September 13 - 17, 2021.

Members of the Virgil C. Summer Nuclear Station training staff administered the written examination on September 23, 2021. Six Reactor Operator (RO) and six Senior Reactor Operator (SRO) applicants were administered the examination. All applicants passed both the operating test and written examination. All applicants were issued licenses commensurate with the level of examination administered.

There were two post-examination comments.

No findings were identified.

REPORT DETAILS

OTHER ACTIVITIES

4OA5 Operator Licensing Examinations

a. Inspection Scope

The NRC reviewed the licensees examination security measures while preparing and administering the examinations to ensure compliance with 10 CFR §55.49, Integrity of examinations and tests.

The NRC performed an audit of license applications during the preparatory site visit to confirm that they accurately reflected the subject applicants qualifications in accordance with NUREG-1021.

The NRC administered the operating tests during the period September 13-17, 2021.

The NRC examiners evaluated six Reactor Operator (RO) and six Senior Reactor Operator (SRO) applicants using the guidelines contained in NUREG-1021. Members of the Virgil C. Summer Nuclear Station training staff administered the written examination on September 23, 2021. Evaluations of applicants and reviews of associated documentation were performed to determine if the applicants, who applied for licenses to operate the Virgil C. Summer Nuclear Station, met the requirements specified in 10 CFR Part 55, Operators Licenses.

The NRC evaluated the performance or fidelity of the simulation facility during the preparation and conduct of the operating tests.

b. Findings

No findings were identified.

The facility developed both the operating tests and the written examinations. All examination material was developed in accordance with the guidelines contained in Revision 11, of NUREG-1021. Examination changes agreed upon between the NRC and the licensee were made per NUREG-1021 and incorporated into the final version of the examination material.

All applicants passed both the operating test and written examination and were issued licenses.

Copies of all individual examination reports were sent to the facility Training Manager for evaluation of weaknesses and determination of appropriate remedial training.

The licensee submitted two post-examination comments concerning the operating test and no comments concerning the written examination. A copy of the final written examinations and answer keys, with all changes incorporated, may be accessed not earlier than September 27, 2023, in the ADAMS system (ADAMS Accession Number(s)

ML21279A228 and ML21279A222). A copy of the licensees post-examination comments may be accessed in the ADAMS system (ADAMS Accession Number ML21279A219.

FACILITY POST-EXAMINATION COMMENTS AND NRC RESOLUTIONS

The facility submitted two post-examination comments as indicated in a letter which can be

found in ADAMS under Accession Number ML21279A219.

Post-Examination Comment #1:

Comment: 2021 NRC JPM A1-b (SRO)

The JPM required candidates to determine shift manning requirements given a set of

parameters. One candidate observed that the attachment they were given did not match the

attachment in the frozen procedures folder. The revision had a different name for one of the

watchstanders and who was responsible for filling this attachment out.

Facility Licensee Recommendation

This did not impact the administration or performance of this JPM in any fashion. This was

solely a visual issue and it did not change any answers or critical steps.

.

NRC Resolution:

Once the error was identified during administration the NRC examiner determined the correct

revision of the attachment would be given to the applicants. Both versions of the attachment will

be added to ADAMS in accordance with NUREG-1021, Rev. 11, ES-501, Section F.1. The

error did not affect the JPM task standard or the applicants ability to successfully complete the

task.

Post-Examination Comment #2:

Comment: 2021 NRC JPM A1-a (SRO)

The JPM required candidates to review a set of logs and determine any deficiencies. Reactor

BLDG Temp - IPCS is above the allowed value on the logs. One candidate manually

recalculated this temperature out using the equation from the logs. When they did this, it was

determined that the AO wrote down the incorrect value and that the Reactor BLDG Temp was

actually within the allowed band.

Facility Licensee Recommendation

During the performance of the A 1-a JPM for SROs, one candidate performed the JPM

differently than how it was validated. This led to a new correct way to complete the

JPM correctly.

During validation, all candidates reviewed the CB Tech Spec Rounds and found that

REACTOR BUILDING TEMPERATURE was logged at 119.1°F, which is above the

maximum allowed value of 118.3°F. There is a calculation to find the average Reactor Building

Temperature. This specific point that is logged from IPCS, already takes this calculation into

account. All validators saw the value above the maximum allowed of 118.3°F, applied the

Technical Specification of 3.6.1.5.

During the performance of this JPM, one candidate manually recalculated the average

Reactor Building Temperature using the formula and points that are given in the CB TECH

SPEC ROUNDS logs. When performing the manual calculation, an average Reactor Building

Temperature of 111.2°F was calculated, which is in specifications for allowed average Reactor

Building Temperature.

The candidate than said that the value was incorrectly written down and there is no need to

enter Technical Specification 3.6.1.5. The candidate is correct with his statement.

The facility recommends that this JPM have two correct answers. Because the specific IPCS

point already calculates the average temperature, those that read 119.1 °F and applied

Technical Specification 3.6.1.5 would be correct since this is how the JPM was intended to be

written. If the candidate manually calculated the average Reactor Building Temperature out and

determined the value was incorrectly logged and therefore Technical Specification 3.6.1.5 is not

applicable, is also correct. In accordance with NUREG 1021, ES-303, two correct answers

should be accepted because there was a deficiency in the procedure (CB rounds handout) that

was beyond the applicant's control. Both methods have validity to the way you answer the

questions to complete the JPM satisfactorily. Both methods allowed the candidate to find an

error within the logs.

NRC Resolution:

The NRC concurs with the facilities recommendation. The initial design of the JPM failed to

accurately ensure the data feeding the calculation was correct, it was assumed that an applicant

would not go back and recalculate a data point. However, since an applicant did go back and

recalculate the data point, his method and approach to the log review was acceptable.

Both versions of the modified answer key will be added to ADAMS in accordance with NUREG-

21, Rev. 11, ES-501, Section F.1.
