REPORT DETAILS
4OA5 Other Activities
.1 Initial Licensing Examinations
a. Examination Scope
The U.S. Nuclear Regulatory Commission (NRC)examiners and members of the facility licensee's staff used the guidance prescribed in NUREG
-1021, "Operator Licensing Examination Standards for Power Reactors," Revision 1 1, to develop, validate, administer, and grade the written examination and operating test. The written examination outlines were prepared by the NRC staff and were transmitted to the facility licensee's staff.
Members of the facility licensee's staff prepared the operating test outlines and developed the written examination and operating test. The NRC examiners validated the proposed examination during the week of Ju l y 24, 2017, with the assistance of members of the facility licensee's staff. During the on
-site validation week, the examiners audited all license application s for accuracy. The NRC examiners, with the assistance of members of the facility licensee's staff, administered the operating test, consisting of job performance measures and dynamic simulator scenarios, during the period of August 21 to August 29 , 2017. The facility licensee administered the written examination on August 31, 2017.
b. Findings
- (1) Written Examination The NRC examiners determined that the written examination, as proposed by the licensee, was within the range of acceptability expected for a proposed examination.
Less than 20% of the proposed examination questions were determined to be unsatisfactory and required modification or replacement.
All changes made to the proposed written examination, were made in accordance with NUREG-1021, "Operator Licensing Examination Standards for Power Reactors," and documented on Form ES 9, "Written Examination Review Worksheet
." On September 5, 2017 , the licensee submitted documentation noting that there were no post-examination comment s for consideration by the NRC examiners when grading the written examination
. The written examination outlines and worksheets, the proposed written examination, as well as the final as
-administered examination and answer key (ADAMS Accession Number ML17068A43 2), will be available
, in 24 months
, electronically in the NRC Public Document Room or from the Publicly Available Records component of NRC's Agencywide Document Access and Management System (ADAMS). The NRC examiners graded the written examination on Septemb er 6, 2017, and conducted a review of each missed question to determine the accuracy and validity of the examination questions.

- (2) Operating Test The NRC examiners determined that the operating test, as originally proposed by the licensee, was within the range of acceptability expected for a proposed examination. Following the review and validation of the operating test, minor modifications were made to several Job Performance Measures (JPMs), and some minor modifications were made to the dynamic simulator scenarios. Changes made to the operating test
, documented on Form ES 7, "Operating Test Review Worksheet" as well as the final
, as-administered
, dynamic simulator scenarios and JPMs, will be available, in 24 months, electronically in the NRC Public Document Room or from the Publicly Available Records component of NRC's ADAMS. The NRC examiners completed operating test grading on September 14, 2017.
- (3) Examination Results Eight applicants at the senior reactor operator level were administered written examinations and operating tests.
All eight applicants passed all portions of their examinations and were issued their respective operating licenses on September 21, 2017.
.2 Examination Security
a. Scope
The NRC examiners reviewed and observed the licensee's implementation of examination security requirements during the examination validation and administration to assure compliance with Title 10 of the Code of Federal Regulations, Section 55.49, "Integrity of Examinations and Tests
." The examiners used the guidelines provided in NUREG-1021, "Operator Licensing Examination Standards for Power Reactors
," to determine acceptability of the licensee
's examination security activities.
b. Findings
None
4OA6 Management Meetings
.1 Debrief The chief examiner presented the examination team's preliminary observations and findings on August 29, 2017 , to J. Washko , Plant Manager
, and other members of the Dresden Nuclear Power S tation staff.
.2 Exit Meeting
The chief examiner conducted an exit meeting on September 12, 2017, with Mr. D. Thomas III , Training Manager

SIMULATION FACILITY FIDELITY REPORT
Facility Licensee:
Dresden Nuclear Power
S tation Facility Docket No: 50-237; 50-249 Operating Tests Administered:
August 21 through 29, 2017 The following documents observations made by the U.S. Nuclear Regulatory
Commission (NRC) examination team during the initial operator license examination. These observations do
not constitute audit or inspection findings and are not, without further verification and review, indicative of non
-compliance with Title 10 of the Code of Federal Regulations
55.45(b). These observations do not affect NRC certification or approval of th
e simulation facility other than to provide information which may be, used in future evaluations.
No licensee action is required in response to these observations.
During the conduct of the simulator portion of the operating tests, the following items wer
e observed: ITEM DESCRIPTION
2-8540-2/4; Drywell Pressure Indicator
During Scenario 2, the Drywell Pressure Indicator did not respond to lowering drywell pressure. After initiating drywell sprays with drywell pressure about 9 psig, about 3 minutes later, the indicator dropped from 9 psig to 3 psig. The licensee replaced a degraded cable which repaired the sluggish indicator.
