NRC examiners provided outline, proposed examination, and post-validation comments to the licensee. The licensee satisfactorily completed comment resolution prior to examination administration. For the written examinations initially submitted by the licensee, NRC examiners determined that the reactor operator (RO) written examination was within the range of acceptability expected for a proposed examination but the senior reactor operator-only (SRO-only) portion of the written examination was not within the range of acceptability expected for a proposed examination.

The NUREG-1021 standard for an acceptable submittal requires that 20 percent or fewer of questions submitted for the RO and SRO-only written examinations (assessed separately) require replacement or significant modification. For this submittal, the SRO-only portion of the examination contained 8 questions (32 percent) that required replacement or significant modifications. The major issue was questions that did not match the selected knowledge and ability statement; other errors included questions not written at an SRO-only level, two or more distracters that were not credible and questions that had multiple correct answers. As identified in NUREG-1021, future written examination submittals should incorporate any lessons learned stemming from this examination effort. The licensee wrote Condition Report 00102279 to address these issues.

No findings were identified. During administration of the operating test scenarios, the examiners were informed of three issues affecting examination integrity. Because none of the issues resulted in replacing or modifying any test items, the issues were evaluated as not more than minor, but are identified here per guidance in NUREG-1021, ES-501, Section E.3.a. Issue 1: Scenario #1:  A book containing several abnormal (off-normal)procedures was not updated after the first scenario run but was returned to the simulator for use in subsequent runs. As a result, one BOP applicant discovered one event procedure was missing and in subsequent event, the same BOP applicant discovered a procedure that had place-keeping marks from the previous scenario run. NRC examiners determined the impact as minor since a replacement procedure was readily available to the BOP applicant and the place-keeping marks offered no discernable advantage to the applicant. The licensee wrote Condition Report 00101585 to address this issue.

Issue 2: Scenario #3: A cue was given by the booth operator to the CRS applicant without prior concurrence of the lead examiner.

SUMMARY

ER 05000482/2015301; 11/13/2015 - 12/29/2015; Wolf Creek Generating Station; Initial

Operator Licensing Examination Report.

NRC examiners evaluated the competency of eight applicants for reactor operator licenses and seven applicants for an instant senior reactor operator license at Wolf Creek Generating Station.

The licensee developed the examinations using NUREG-1021, "Operator Licensing Examination Standards for Power Reactors," Revision 10. The written examination was administered by the licensee on November 13, 2015. The NRC examiners administered the operating tests November 16-23, 2015.

The examiners determined that 14 of the 15 applicants satisfied the requirements of 10 CFR Part 55, and the appropriate licenses have been issued. However, 2 reactor operator applicants and 1 instant senior reactor operator applicant had the issuance of their license delayed until any written examination appeal can be reviewed for possible impact on their licensing decision in accordance with NUREG-1021, Revision 10, ES-501, Section D.3.c.

REPORT DETAILS

OTHER ACTIVITIES (OA)

4OA5 Other Activities (Initial Operator License Examination)

.1 License Applications

a. Scope

NRC examiners reviewed all license applications submitted to ensure each applicant satisfied relevant license eligibility requirements. The examiners also audited four 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 Examination Development

a. Scope

NRC examiners reviewed integrated examination outlines and proposed examinations submitted by the licensee against the requirements of NUREG-1021. The NRC examination team conducted an onsite validation of the operating tests.

b. Findings

No findings were identified.

NRC examiners provided outline, proposed examination, and post-validation comments to the licensee. The licensee satisfactorily completed comment resolution prior to examination administration.

For the written examinations initially submitted by the licensee, NRC examiners determined that the reactor operator (RO) written examination was within the range of acceptability expected for a proposed examination but the senior reactor operator-only (SRO-only) portion of the written examination was not within the range of acceptability expected for a proposed examination.

The NUREG-1021 standard for an acceptable submittal requires that 20 percent or fewer of questions submitted for the RO and SRO-only written examinations (assessed separately) require replacement or significant modification. For this submittal, the SRO-only portion of the examination contained 8 questions (32 percent) that required replacement or significant modifications. The major issue was questions that did not match the selected knowledge and ability statement; other errors included questions not written at an SRO-only level, two or more distracters that were not credible and questions that had multiple correct answers. As identified in NUREG-1021, future written examination submittals should incorporate any lessons learned stemming from this examination effort. The licensee wrote Condition Report 00102279 to address these issues.

NRC examiners determined the operating tests initially submitted by the licensee were within the range of acceptability expected for a proposed examination.

All 15 applicants passed all portions of the operating test. Fourteen of the 15 applicants passed the written examination. The final written examinations and post-examination analysis may be accessed in the ADAMS system under the accession numbers noted in the attachment. There were no post-examination comments submitted by the licensee.

The licensee requested and received approval by the NRC to withhold the written examinations from the public document room for 24 months after the administration date.

The examination team noted a generic weakness during the administration of the job performance measure associated with the ability to develop a Protective Action Recommendation. Seven out of seven instant senior reactor operator applicants failed to complete one or more portions of the emergency notification form correctly and within the established time limit. The licensee wrote Condition Report 00102021 to address this issue.

.4 Simulation Facility Performance

a. Scope

The NRC examiners observed simulator performance with regard to plant fidelity during examination validation and administration.

b. Findings

No findings were identified.

During the performance of one simulator job performance measure, NRC examiners observed a possible simulator hardware issue. While performing actions to restore power to a vital bus following a loss of all ac power, the normal feeder breaker NB HIS-4 failed to close, tripping on the attempt. With the assistance of a simulator engineer, a fix was identified and administration of the operating test continued with minimal delay. It is noted that during NRC validation of the operating test, this job performance measure was performed as scripted. See Enclosure 2 for additional details.

.5 Examination Security

a. Scope

The NRC examiners reviewed examination security during both the onsite preparation week and examination administration week for compliance with 10 CFR 55.49 and NUREG-1021. Plans for simulator security and applicant control were reviewed and discussed with licensee personnel.

b. Findings

No findings were identified.

During administration of the operating test scenarios, the examiners were informed of three issues affecting examination integrity. Because none of the issues resulted in replacing or modifying any test items, the issues were evaluated as not more than minor, but are identified here per guidance in NUREG-1021, ES-501, Section E.3.a.

Issue 1: Scenario #1: A book containing several abnormal (off-normal)procedures was not updated after the first scenario run but was returned to the simulator for use in subsequent runs. As a result, one BOP applicant discovered one event procedure was missing and in subsequent event, the same BOP applicant discovered a procedure that had place-keeping marks from the previous scenario run.

NRC examiners determined the impact as minor since a replacement procedure was readily available to the BOP applicant and the place-keeping marks offered no discernable advantage to the applicant. The licensee wrote Condition Report 00101585 to address this issue.

Issue 2: Scenario #3: A cue was given by the booth operator to the CRS applicant without prior concurrence of the lead examiner. The cue was inappropriately given prior to the CRS applicant identifying that a load reduction was required. However, NRC examiners determined the impact as minor since the applicant had multiple other opportunities to be evaluated in the Directing Operations competency. The licensee wrote Condition Report 00101586 to address this issue.

Issue 3: Scenario #2: A laminated copy of EMG E-0, REACTOR TRIP OR SAFETY INJECTION, Foldout Page, grease pencil markings were not wiped clean between the 2nd and 3rd applicant crews. NRC examiners determined the impact as minor since the grease pencil markings offered no discernable advantage to the applicant who identified the markings. The licensee wrote Condition Report 00101587 to address this issue.

In addition, the licensee wrote Condition Report 00101655, Trending CR for OPS Exam Security Issues, to track corrective actions for an adverse Operations examination security trend.

4OA6 Meetings, Including Exit
