Dear Mr. Welsch:
On March 1, 2021, the U.S. Nuclear Regulatory Commission (NRC) completed an initial
operator license examination at your Diablo Canyon Power Plant, Units 1 and 2. The enclosed
report documents the examination results and licensing decisions. The preliminary examination
results were discussed on February 3, 2021, with Ms. P. Gerfen, Site Vice President, and other
members of your staff. A telephonic exit meeting was conducted on March 1, 2021, with
Mr. A. Kadir, Exam Supervisor, who was provided the NRC licensing decisions.
The examination included the evaluation of fifteen applicants for reactor operator licenses, four
applicants for instant senior reactor operator licenses and one applicant for an upgrade senior
reactor operator license. The license examiners determined that all applicants satisfied the
requirements of 10 CFR Part 55, and the appropriate licenses have been issued. There were
no post-examination comments submitted by your staff. The enclosure contains details of this
report.
No findings were identified during this examination.

REPORT DETAILS
OTHER ACTIVITIES - INITIAL LICENSE EXAMINATION
.1
License Applications
a.
Scope
The NRC examiners reviewed all license applications submitted to ensure each
applicant satisfied relevant license eligibility requirements. The NRC 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
The NRC examiners reviewed integrated examination outlines and draft examinations
submitted by the licensee against the requirements of NUREG-1021. The NRC
examiners conducted an onsite validation of the operating tests.
b.
Findings
The NRC examiners provided outline, draft examination and post-validation comments
to the licensee. The licensee satisfactorily completed comment resolution prior to
examination administration.
The NRC examiners determined the written examinations and operating tests initially
submitted by the licensee were within the range of acceptability expected for a proposed
examination.

.3
Operator Knowledge and Performance
a.
Scope
On February 12, 2021, the licensee proctored the administration of the written
examinations to all twenty applicants. The licensee staff graded the written
examinations, analyzed the results, and presented their analysis to the NRC on
February 22, 2021.
The NRC examination team administered the various portions of the operating tests to
all applicants on January 25 - February 3, 2021.
b.
Findings
No findings were identified.
All applicants passed the written examination and all parts of the operating tests. 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 as indicated in the licensee submittal.
The examination team noted no generic weaknesses associated with applicant
performance on the operating tests. The licensee identified four generic weaknesses
associated with applicant performance on the written examinations:
1.
Pressurizer Level Post-Accident Monitoring (PAM) instruments - 12 of 20
missed Question 3
2.
Loss of battery charger versus loss of battery bus (indications) - 11 of 20 missed
Question 23
3.
Notification times for a fire in containment - 3 of 5 missed Question 83
4.
Who approves troubleshooting activities - 3 of 5 missed Question 97
These deficiencies were captured in the licensees corrective action program as
Notification 51108054. Copies of all individual examination reports were sent to the
facility training manager for evaluation and determination of appropriate remedial
training.
.4
Simulation Facility Performance
a.
Scope
The NRC examiners observed simulator performance regarding plant fidelity during
examination validation and administration.
b.
Findings
No findings were identified.
.5
Examination Security
5
a.
Scope
The NRC examiners reviewed examination security for examination development during
both the onsite preparation week and examination administration week for compliance
with 10 CFR 55.49 and NUREG-1021. Plans for examination security and applicant
control were reviewed and discussed with licensee personnel.
b. Findings
No findings were identified.
