.* EXECUTIVE SUMMARY Monticello Nuclear Generating Station NRC Examination Report 50-263/99301(OL) A licensee developed and NRC approved initial operator licensing examination was administered to two reactor operator license applicants using the requirements stated in NUREG-1021, " Operator Licensing Examination Standards for Power Reactors," Interim Revision 8, January 1997. This examination process consisted of a one week examination preparation and validation period, and a three day examination administration period.

Additionally, the NRC examiners observed a period of routine operations in the control room.

Results: Both reactor operator license applicants passed all portions of their respective

examinations and were issued reactor operator licenses for the Monticello Nuclear Generating Station. Based upon the applicants' performance, the examination team concluded that the applicants were well prepared for the licensing examination. (Section 05.4) Report Summarv: Control room operators demonstrated appropriate control and awareness during

abnormal evolutions while maintaining steady state operations. In general, the licensed - operators demonstrated appropriate knowledge and understanding of plant system status. (Section 01.1) The operations procedures were appropriately written to direct the safe operation of the

plant. No operational deficiencies were identified during the examination development, validation, or administration. (Section O3.1) The licensee provided knowledgeable stafMuring the validation process. The licensed

operators, who served as surrogate senior reactor operators during a portion of the exam's' administration, demonstrated appropriate operator command and control during all abnormal events. (Section 04.1) , While the licensee had established appropriate procedures to control test material j

integrity, the examination team identified a lack of plant staff understanding regarding current examination security measures that resulted in an examination compromise.

The licensee took appropriate short-term corrective actions to prevent any additional exam compromise.' (Section 05.1)

The licensoe developed examination as originally submitted did not meet all of the necessary requirements listed in NUREG-1021 to be a valid licensing test. The written test required substantial modification and the operating test required only moderate . modification _ to make them consistent with NUREG-1021. The examination team identified the written examination development area as needing improvement. (Section 05.2)

e.

.- The plant specific simulator provided realistic plant response throughout the operating i

test. (Section 05.3) i The applicants were well prepared for the licensing examination. No programmatic - weaknesses were identified. (Section 05.4) The licensee's performance during post-examination activities was satisfactory.

f - However, the NRC post-examination review revealed a potential weakness in the j licensee's verification process in the job performance measures (JPM) question area of the operating test. (Section 05.5) , i t i . n i

un Report Details - 1. Operations 01-Conduct of Operations 01.1 Main Control Room Observations

a.

Scooe (71707) i Using inspection Procedure 71707, Plant Operations, the NRC examination team . observed control room operations and questioned the licensed operators on plant status during a two-hour period. That observation included operator response to a failed component and performance during a routine surveillance activity.

b.

Observations and Findinas In general, the examination team observed proper face-to-face communications, operator response to plant alarms, procedure usage, and decision making processes during steady state operations. The examination team also observed surveillance testing for a fire alarm for the emergency diesel generator room and the reactor building ventilation wide range gas monitors (WRGMs). The reactor building ventilation WRGMs testing was partially completed but had to be stopped due to a component failure.

During the observation period, the examination team noted the following: Distractions in the main control room were minimized and control room access

. was limited.

Control room operators were attentive to the control panel indications and

anticipated all expected alarms associa*.ed with testing in progress.

Plant operators informed the shift supervisor of problems encountered, such as

the failure of WRGM's 'B' channel to purge, during surveillance testing.

The shift manager promptly declared the 'B' channel of WRGM inoperable and entered Technical Specifications as required.

.When questioned by the examination team, the control room operators appeared knowledgeable of the current plant status. However, the operators were unable to describe the reason for a high pressure coolant injection gland seal condenser's condensate pump control switch being in the "run" position versus the normal " auto" position.. The examination team received clarification on the switch's position from the licensee staff during the administration of the examination.

.4 __ y & c.

Conclusions . Control room operators demonstrated appropriate control and awaren3ss during testing evolutions while maintaining steady state operations. In general, the licensed operators demonstrated appropriate knowledge and understanding of plant system status.

~ O3 Operations Procedures and Documentation 03.1 Operations Procedures a.

Scooe (71707) Using inspection Procedure 71707, Piant Operations, the examination team reviewed portions of selected administrative and operating procedures. This review was part of l the licensing examination verification and validation process, j b.

Observations and Findinas The examination team reviewed a variety of plant procedures that included normal operating procedures, abnormal operating procedures, annunciator response procedures, emergency operating procedures, and administrative procedures. The examination team did not identify any deficiencies with the procedures referenced. In general, the procedures contained appropriate instructions, notes, precautions, limitations, and cautions to direct operations in a safe manner.

c.

Conclusions The operations procedures were appropriately written to direct the safe operation of the plant. No operational deficiencies were identified during the examination development, validation, or administration.

04' Operator Knowledge and Performance 04.1 Examination Development and Suooort a.

Scope The examination team used guidance in NUREG-1021, sections ES-301 and ES-401, to verify and validate the licensee submitted examination material. That verification included the observed performance of two licensed operators, who served as surrogate senior reactor operators, during the administration of the operating test.

. b.

Observations and Findinas During the verification and validation phase, the licensee staff demonstrated a high level of plant specific knowledge and understanding. However, the examination team i

identified a common misunderstanding in the construction of acceptable written questions for a multiple choice type examination. The training staff promptly corrected

i

e ' all examination team identified errors and provided revised written questions suitable for validation. See section 05.2 for a complete discussion on the quality of the test material.

During the administration of the dynamic simulator portion of the operating test, the examination team observed two licensed operators. These operators performed surrogate senior reactor operators duties to augment the crew composition since only two reactor operator applicants were tested. The surrogate operators demonstrated appropriate procedure usage, effective communications, and proper command and control. Their appropriate performance contributed to the validity of the examination as administered.

c.

Conclusions The licensee provided knowledgeable staff during the validation process. The licensed operators, who served as a surrogate senior reactor operators during a portion of the exam's administration, demonstrated appropriate operator command and control during all events.

Operator Training and Qualification 05.1 Pre-Examination Activities: Examination Security a.

Scope Licensee's training staff developed the licensing examination outline and test material using guidance in NUREG 1021, sections ES-301 and ES-401. The examination outline and material were reviewed by the NRC examination team using the same guidance.

b.

Observations and Findinas The licensee's staff delivered the licensing examination outline and test material as scheduled in properly sealed envelopes. The necessary quality check forms were also included with that delivery.

Prior to the administration of the examination, the licensee identified one example of a violation of NRC examination integrity requirements and promptly notified the examination team. Specifically,10 CFR 55.49 required all applicants, licensees, and facility licensees to not engage in any activity that compromises the integrity of any application, test, or examination required by 10 CFR 55, which includes initial NRC licensing examination activity. The following details were provided to the NRC: On July 12,1999, one crew of licensed operators signed on to a security agreement form then participated in a review of the written examination questions. On July 19, 1999, the same crew was approached by one of the two license applicants and agreed to orally examine the applicant by conducting an on-the-job-training session relating to electrical breaker alignment, security key control system, control room logs, reportable -

. . -

e ' occurrences, and the reporting of abnomial conditions._ Licensee management became aware of the potential examination compromise on July 21,1999 and promptly informed the NRC. Licensee management provided the examination team supporting documentation which were analyzed to establish the impact on the test material - integrity. The examination team determined that one question on the written examination had to be replaced by the licensee's staff. The examination team determined that appropriate procedures were in place but a lack of management emphasis on examination security led to a violation of NRC requirements. The licensee took prompt corrective action to inform the licensed operators of their responsibilities.

This Severity Level IV violation is being treated as a Non-Cited Violation (NCV), consistent with Appendix C of the NRC Enforcement Policy (VIO 50-263/99301-01).

This violation is in the licensee's corrective action program as condition report No.

99002059.

c.

Conclusions While the licensee had established appropriate procedures to control test material integrity, the examination team identified a lack of plant staff understanding regarding current examination security measures that resulted in examination compromise. The licensee took appropriate short-term corrective actions to prevent any additionai exam compromise.

05.2 Pre-Examination Activities: Quality of Submitted Materials a.

Scope The licensee's tr6ining staff developed the test outline and material using guidance in NUREG 1021, sections ES-301 and ES-401. The licensing examination was reviewed by the NRC examination team for validity and consistency with the guidance in NUREG-1021.

b.

Observations and Findinas (1) Written Test: The written examination as originally submitted did not meet the requirements of NUREG-1021, sections ES-401 and Appendix B. The i examination team identified that 22 test items of the 100 question examination contained deficiencies associated with the question construction. The NRC informed the licensee's oversight manager, who was responsible for the examination development and review process, that a number of deficiencies had been identified. Based on that conversation, the licensee applied additional resources into correcting those deficiencies prior to the administration of the examination. The most significant deficiencies included the following examples: i ' Five questions were not written to match the selected knowledge / ability a (K/A) item chosen from NUREG-1023," Knowledge and Abilities Catalog for Nuclear Power Plant Operators-Boiling Water Reactors," Revision 2, June 1998. This was contrary to the guidance of NUREG-1021, Appendix B, Section C.1.b.

t ,o One question contained a low content validity in that it did not have a

direct, important relationship to the applicant's ability to perform the duties of a reactor operator. This was contrary to the guidance of NUREG-1021, Apper; dix B, Section C.1.a.

Two questions were ambiguous and lacked sufficient focus to elicit the - correct answer. This was contrary to the guidance of NUREG-1021, Appendix B, Section C.1.c.

Four questions contained more than one plausible answer choice. This = was contrary to the guidance of NUREG-1021, Appendix B, Section B.2.

Three questions contained no correct answer choice. This was contrary . to the guidance of NUREG-1021, Appendix B, Section B.2.

Five questions contained an unclear answer choice or a highly - implausible distractor. This was contrary to the guidance of NUREG-1021, Appendix B, Sections C.1.c, C.2.g, and C.2.h.

One question contained a collection of true-false statements in the - answer choices. This was contrary to guidance of NUREG-1021, Appendix B, Section C.2.c.

One question contained specific determiners or clues pointing to the - correct answer choice. This was contrary to the guidance of NUREG-1021, Appendix B, Section C.2.m.

The licensee staff replaced or significantly modified each question identified as being unsatisfactory. These changes exceeded the normally required changes of 10% or less that would be expected on a licensee developed examination.

( 2) Ooeratina Test: The operating examination as submitted did not meet the requirements of NUREG-1021, sections ES-301 and Appendix C & D. These inconsistencies are noted below: Cateaory A-Administrative Tooles: The administrative items as originally submitted did not meet the requirements in ES-301. Specific deficiencies i included: One question contained a low discriminatory value when distinguishing j - between a competent and an incompetent operator. This was contrary to ] the guidance in section D.1.d.

I One question required knowledge of an unrelated duty as associated with - a reactor operator. This was contrary to the guidance in section D.2.d.

I Cateaory B - Control Room Systems & Facility Walk-throuah: The walk-through items as originally submitted did not meet the requirements ES-301 and Appendix C. Specific deficiencies included:

1

r . **. Two of the 10 job performance measures (JPM) submitted had been ' . used during an audit exam for the applicants. This duplication was contrary to the guidance in section D.1.a.

One control room systems JPM contained only one control panel switch + manipulation to complete the task. Even though the assigned task was safety significant, the JPM did not provide a legitimate basis for evaluating the applicant's ability to safely operate the facility. This was contrary to the guidance in section D.1.d and Appendix C.

. Five c/ the 10 JPMs lacked meaningful performance standards to allow

the eLamination team to evaluate successful progress toward completing the task. This was contrary to the guidance in Appendix C.

Cateaorv C - Intearated Plant Ooerations: The dynamic simulator scenarios as submitted did not meet the requirements in ES-301 and Appendix D. Specific deficiencies included: Scenario No.1 lacked specific expected operator actions for 5 of the 8 - events. Operator actions such as start a component or verify a plant parameter had not been included. This was contrary to the guidance in Appendix D.

Scenario No. 2 lacked specific expected operator actions for 4 of the 9 - events. Operator actions such as start a component or verify a plant parameter had not been included. This was contrary to the guidance in Appendix D.

Scenarios No.1 and' No. 2 contained one event each that lacked any l - measurable performance indicator needed to verify the ability of the ' applicants to safety operate the plant. This was contrary to the guidance in section D.4.d.

, Th'e licensee staff replaced or significantly modified each test item on the operating test identified as being unsatisfactory. In general, these changes were consistent with other licensee developed examinations, c.

Conclusions The licensee developed examination as originally submitted did not meet all of the necessary requirements listed in NUREG-1021 to be a valid licensing test. The written test required substantial modification and the operating test required moderste modification to make them consistent with NUREG-1021. The examination team identified the written examination development area as needing improvement. Licensee management acknowledged the performance deficiency as needing attention.

E j 't ' 05.3 Examination Administration ar"1 Staff Suooort a.

Scope ) The examination team administered an operating test to two license applicants using ' - guidance in NUREG-1021, ES-302. The training staff administered an NRC approved written test to the same two license applicants using guidance in NUREG-1021, ES-402.

b.

Observations and Findinos The examination team identified no significant examination administration or licensee support deficiencies. The licensee's training staff consistently and correctly established the required simulator conditions. The simulator was properly set up for each scenario and the prescripted malfunctions were properly inserted in a timely manner. In addition, the training staff effectively coordinated the availability of the simulator and plant during the walk-through portion of the operating test. Licensee staff, who participated as support personnel (e.g., technicians, engineers, in-plant operators, etc.) during the scenarios, provided appropriate feedback and communications to the applicants.

c.

Conclusions The training staff provided appropriate support during the administration of all portions of the operating test. The plant specific simulator provided realistic plant response throughout the operating test.

05.4 License Aoolicant Performance a.

Scope Initial operator licensing examinations were administered to two reactor operator applicants during the week of August 23,1999, in accordance with NUREG-1021. The examination team documented the applicants' performance using guidance in NUREG-1021, ES-501.

b.

Qbservations and Findinas-Written Examination Performance: Both applicants achieved greater than 90.0% on the written examination and given a passing score. The relatively high score achieved by each applicant demonstrated an appropriate level of preparation. Only one question was answered incorrectly by both applicants. The subject matter of the missed question related to the operation of the fuel pool cooling system during a loss of the reactor building closed cooling water system.

Ooeratina Test Performance: Both applicants passed all portions of the operating test.

After the operating test grading was finalized, the examination team identified three generic weaknesses.

A knowledge weakness associated with the main steam isolation valve closure

scram logic;

l i i

n' j

y

- A performance weakness associated with approved procedure adherence; and

A performance weakness associated with using three-way communications.

These generic items did not constitute a programmatic weakness in the Monticello training program but should be considered for incorporation into the systematic approach to training (SAT) program.

c.

Conclusions The examination team concluded that the applicants were well prepared for the licensing examination. The examination team identified no programmatic weaknesses.

O5.5 Post Examination Activities a.

Examination Scope The examination team conducted post-examination activities using the guidelines contained in NUREG-1021, ES-501.

b.

Observations and Findinas The examination team identified no deficiencies with the licensee's staff performance during the post-examination activities. Following the completion of the examination, the NRC examination team requested the assistance of the licensee's training personnel to clarify five JPM question area responses that were somewhat different than the validated answer key. The examination team was informed that the altemate responses were correct answers and should be given full credit. The examination team determined that the licensee's validation of the JPM question area had not been all inclusive.

The licensee did not have any post written examination comments. The examination team's post-examination review revealed no changes. The as-administered licensing examination was deemed valid.

c.

Conclusions The licensee's performance during post-examination activities was satisfactory.

However, the post-examination review revealed a potential weakness in the licensee's verification process for the job performance measures (JPM) question area of the operating test.

' 05.6 Simulator Fidelity -. The examination team observed no simulator modeling or simulator performance deficiencies during examination validation or administration.

e '

Miscellaneous Operations issues 08.1 (Closed) Unresolved item 50-263/99010-01(DRS): Licensed operator maintaining active status issue. The licensee's Technical Specifications Table 6.1.1, "Minimurn Shift Crew Composition," only specified four licensed operators (two licensed reactor operators and two licensed senior reactor operators) as being needed to operate the facility. However, the licensee had identified a third licensed senior reactor operator (SRO) position (NLPE&RO) as being required in the control room and had been giving that position credit for maintaining an active SRO license.

On June 15,1999, the operations department issued an operations policy statement (No. 99-01) to clarify the expectations for maintaining an active license. Specifically, the NLPE&RO position would not be recognized as a SRO license required position by plant administrative procedures. The duties and responsibilities of the NLPE&RO were consistent with those of a reactor operator (RO) licensed counterpart. The SRO licensed NLPE&RO position would require training, examination, and evaluation in the SRO position during annual requalification training to maintain a current SRO license.

This item will be closed based upon the licensee's corrective action to clarify the license status expectations for a NLPE&RO position.

V. Manaaement Meetinas X1 Exit Meetina Summary The Chief Examiner presented the examination team's observations and preliminary findings to members of the licensee's management on August 25,1999. The licensee was contacted on September 10,1999, to inform plant management of the examination results. The licensee acknowledged the findings as presented. No proprietary information was identified during the development and administration of the examination or at the exit meeting.
