SUBJECT:

CALLAWAY PLANT - NRC EXAMINATION REPORT 05000483/2013301

Dear Mr. Heflin:

On March 26, 2013, the U.S. Nuclear Regulatory Commission (NRC) completed an initial operator license examination at Callaway Plant. The enclosed report documents the examination results and licensing decisions. The preliminary operating test results were discussed on March 22, 2013, with Mr. M. Hall, Director Nuclear Operations; Ms. S. Banker, Director Training; and other members of your staff. A telephonic meeting was conducted on May 1, 2013, with Mr. B. Cox, Senior Director Nuclear Operations, and other members of your staff who were provided preliminary examination results and the NRC-identified violation. A telephonic exit meeting was conducted on May 2, 2013, with Mr. L. Wilhelm, Operations Supervisor - Training, who was provided the NRC licensing decisions.

The examination included the evaluation of four applicants for reactor operator licenses, three applicants for instant senior reactor operator licenses, and three applicants for upgrade senior reactor operator licenses. The license examiners determined that three of the applicants satisfied the requirements of 10 CFR Part 55. One license has been issued and two licenses are being held in abeyance by NRC Region IV until the resolution of a written examination appeal. There was one post examination comment submitted by your staff. Enclosure 1 contains details of this report and Enclosure 2 summarizes post examination comment resolution.

Additionally, an NRC-identified Severity Level IV violation is listed in Section 4OA5 of this report.

The NRC is treating this violation as a non-cited violation consistent with Section 6.4 of the NRC Enforcement Policy because it is a Severity Level IV violation and because it is entered into your corrective action program. If you contest the violation or the significance of the non-cited violation, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555-0001, with copies to the Regional Administrator, U.S. Nuclear Regulatory Commission, Region IV, 1600 E. Lamar Blvd, Arlington, Texas, 76011-4125; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident Inspector at the facility.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS

ER 05000483/2013301; March 18, 2013 - May 2, 2013; Callaway Plant; Initial Operator

Licensing Examination Report.

NRC examiners evaluated the competency of four applicants for reactor operator licenses, three applicants for instant senior reactor operator licenses, and three applicants for upgrade senior reactor operator licenses at Callaway Plant.

The licensee developed the examination and test using NUREG-1021, "Operator Licensing Examination Standards for Power Reactors," Revision 9, Supplement 1. The written examination was administered by the licensee on March 26, 2013. NRC examiners administered the operating test from March 18 through 22, 2013.

The examiners determined that three of the applicants satisfied the requirements of 10 CFR Part 55. One license has been issued and two licenses are being held in abeyance by NRC Region IV until the resolution of a written examination appeal.

Cornerstone: Mitigating Systems

• Severity Level IV. The examination team identified a Severity Level IV, non-cited Violation (NCV), of Title 10 CFR Part 55.49, Integrity of Examination and Tests.

Specifically, the licensee failed to ensure that Door 143, Entrance to Simulator Instructor Booth, remained closed/latched upon personnel exiting the simulator.

This resulted in the failure to ensure examination security requirements were met as required by procedures TDP-ZZ-00019, NRC License Examination Security and Integrity, Revision 019, and TDP-ZZ-00019, Appendix A, Simulator Security Guidelines, Revision 027. The examination compromise existed because personnel not signed onto the examination security agreement could have gained access to the simulator where examination materials were in plain view.

Therefore, unauthorized personnel could have gained knowledge of initial license examination materials during the conduct of the operating test portion of the initial license examination.

The failure to ensure the requirements of procedures TDP-ZZ-00019 and TDP-ZZ-00019, Appendix A, were met resulted in the failure to establish proper examination security. Failure to meet the requirements of approved examination security procedures is a performance deficiency. This performance deficiency was determined to be Severity Level IV because it fits the SL-IV example of Enforcement Policy Section 6.4.d, Violation Examples: Licensed Reactor Operators. This section states, Severity Level IV violations involve, for example: a non-willful compromise of an application, test, or examination required by 10 CFR Part 55. The performance deficiency could have impacted the regulatory process if licensing decisions were made with applicants having prior knowledge of examination materials. However, since the simulator door was only unlatched for a short period of time and all applicants were sequestered under the supervision of licensee examination team personnel, it is deemed that there was no actual effect on the equitable and consistent administration of the exam as a result of the compromise. This is a violation of 10 CFR 55.49,

Integrity of Examination and Tests. There are no cross-cutting aspects assigned to traditional enforcement violations.

Licensee-Identified Violations

None

REPORT DETAILS

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. 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 developed the written exam outline and reviewed all other outlines, draft examination, and test submitted by the licensee against the requirements of NUREG-1021. The NRC examination team conducted an onsite validation of the operating test.

b. Findings

No findings were identified.

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

NRC examiners determined the written examination and operating test initially submitted by the licensee were within the range of acceptability expected for a proposed examination. However, it was noted that both the proposed written examination and operating test contained many administrative errors and the licensee must improve their draft submittals in the future.

.3 Operator Knowledge and Performance

a. Scope

The NRC examination team administered the various portions of the operating test to all applicants on March 18-22, 2013.

On March 26, 2013, the licensee proctored the administration of the written examination to all ten applicants. The original written examination administration date was March 25, 2013, but was delayed one day due to inclement weather. The licensee requested, and NRC Region IV management approved, the one day delay via email. The licensee staff graded the written examinations, analyzed the results, and presented their analysis to the NRC on March 28, 2013.

b. Findings

No findings were identified.

Eight applicants passed the written examination and five applicants passed all parts of the operating test. The final written examination, final operating test, and post examination analysis and comments may be accessed in the ADAMS system under the accession numbers noted in the Supplemental Information attachment. (Public release of the final written examination has been delayed for 24 months from the date of administration at the request of the licensee.) There was one post examination comment submitted by the licensee. The post examination comment recommendation was rejected by the NRC and no changes were made to the written examination answer key. See Enclosure 2 for the question, licensee comment and recommendation, and the NRC resolution.

The examination team noted the following generic weaknesses during administration of the operating test:

(1) One of four RO applicants, two of three SRO-Instant applicants, and two of three SRO-Upgrades failed one or more portions of the operating test.

(2) The majority of SRO applicants demonstrated weak performance on one Administrative Job Performance Measure; Review Shiftly Logs.

(3) Performance of the applicant crews in successfully accomplishing Critical Tasks (CTs) was weak, including SRO-Upgrades. Specifically, crew performance was weak on the following CTs:

a. Establishing Auxiliary Feedwater prior to meeting bleed and feed criteria.

b. Isolating feedwater to a ruptured steam generator.

c. Starting an Emergency Diesel Generator during a loss of all AC event.

While not a generic weakness, the examination team did note that the licensee failed to retain the original simulator performance data (e.g., system pressures, temperatures, and levels) generated during the dynamic operating test until the examination results are final. This requirement is identified in NUREG-1021, Section ES-302, as well as the Notification of NRC Initial Operator Licensing Examination letter sent to Callaway Plant.

The examination team noted the following generic weakness on the written examination:

(1) Of the three RO applicants that passed the written examination, two received a score of 81 percent and one received a score of 80 percent.

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

.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.

.5 Examination Security

a. Scope

The NRC examiners reviewed examination security during both the onsite validation 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.

1. Failure to Maintain Initial Operator Licensing Examination Integrity

A compromise of examination security occurred during administration of the simulator scenario portion of the operating test that resulted in the NRC-identified non-cited violation documented in this section. The finding is being treated under traditional enforcement because the violation, if not found or corrected, had the potential to impact the ability of the NRC to perform its regulatory oversight function.

Specifically, licensing decisions could have been made based on a compromised examination.

Introduction.

The examination team identified a Severity Level IV, non-cited violation (NCV), of Title 10 CFR Part 55.49, Integrity of Examination and Tests.

Specifically, the licensee failed to ensure that Door 143, Entrance to Simulator Instructor Booth, remained closed/latched upon personnel exiting the simulator.

This resulted in the failure to ensure examination security requirements were met as required by procedures TDP-ZZ-00019, NRC License Examination Security and Integrity, Revision 019, and TDP-ZZ-00019, Appendix A, Simulator Security Guidelines, Revision 027. The examination compromise existed because personnel not signed onto the examination security agreement could have gained access to the simulator where examination materials were in plain view. Therefore, unauthorized personnel could have gained knowledge of initial license examination materials during the conduct of the operating test portion of the initial license examination.

Description.

On March 20, 2013, the NRC examination team was conducting the simulator scenario portion of the operating test. During a break for lunch, an NRC examination team member found Door 143, Entrance to Simulator Instructor Booth, was not fully closed/latched. When the team member entered the simulator through the unsecured door, he observed the simulator instructor booth and floor unmanned.

He also observed examination material laid out in the simulator instructor booth.

The team member then informed the NRC chief examiner of the examination security compromise. The chief examiner immediately informed licensee personnel who assumed control of the simulator door. The licensee entered this issue into their corrective action program as Callaway Action Request 2013-01940.

Analysis.

The failure to ensure the requirements of procedures TDP-ZZ-00019 and TDP-ZZ-00019, Appendix A, were met resulted in the failure to establish proper examination security. Failure to meet the requirements of approved examination security procedures is a performance deficiency. This performance deficiency was determined to be Severity Level IV because it fits the SL-IV example of Enforcement Policy Section 6.4.d, Violation Examples: Licensed Reactor Operators. This section states, Severity Level IV violations involve, for example: a non-willful compromise of an application, test, or examination required by 10 CFR Part 55.

The performance deficiency could have impacted the regulatory process if licensing decisions were made with applicants having prior knowledge of examination materials. However, since the simulator door was only unlatched for a short period of time and all applicants were sequestered under the supervision of licensee examination team personnel, it is deemed that there was no actual effect on the equitable and consistent administration of the exam as a result of the compromise.

This is a violation of 10 CFR 55.49, Integrity of Examination and Tests. There are no cross-cutting aspects assigned to traditional enforcement violations.

Enforcement.

Title 10 CFR Part 55.49, Integrity of Examination and Tests, states, in part, Applicants, licensees, and facility licensees shall not engage in any activity that compromises the integrity of any application, tests, or examination required by this part. The integrity of a test or examination is considered compromised if any activity, regardless of intent, affected, or, but for detection, would have affected the equitable and consistent administration of the test or examination. Contrary to the above, the licensee engaged in an activity that compromised the integrity of an application, test, or examination required by this part. Specifically, the licensee failed to ensure the requirements of procedures TDP-ZZ-00019, NRC License Examination Security and Integrity, Revision 019, and TDP-ZZ-00019, Appendix A, Simulator Security Guidelines, Revision 027, were met during administration of the simulator scenario portion of the operating test. If not for detection, this could have affected the equitable and consistent administration of the operating test. This violation is being treated as an NCV, consistent with Section 6.4, Licensed Reactor Operators, of the NRC Enforcement Policy and is designated as Severity Level IV, NCV 05000483/2013301-01, Failure to Maintain Initial Licensing Examination Integrity. The performance deficiency was entered into the licensees corrective action program as AR-2013-01940.
