i - . EXECUTIVE SUMMARY Virgil C. Summer Nuclear Station NRC Examination Report Nos. 50-395/97 300 During the period December 1 - 5. 1997 NRC examiners conducted an announced operator licensing initial examination in accordance with the guidance of Examiner Standards. NUREG-1021. Interim Revision 8.

This examination implemented the operator licensing requirements of 10 CFR S55.41 and S55.45.

Doerations Control room activities were observed during the examination validation

week and examination administration week.

The operators were found to be attentive and professional in their duties (Section 01.1).

Eight Reactor Operator (RO) candidates received written examinations and ' operating tests.

The licensee administered the written examination on December 12. and the NRC administered the operating tests December 1 - 5, 1997 (Section 05.1).

In general, the examiners found that the as-submitted examination was

roarginally acceptable.

The examiners ic'entified the following areas as requirine staff attention or improvement: plausibility of written question distractors, sample plan development, and problem solving character.stics for simulator scenario events (Section 05.2).

Conduct of Operations 01.1 Control Room Observation During validation and administration of the examination, the examiners observed the conduct of the operators in the control room.

The R0s were attentive to evolutions in progress. The SR0s limited personnel access for official busir.ess only, which contributed to a quiet professional atmosphere.

Communicatico standards were adhered to and the operators appeared attentive to evolutions in progress.

Operator Training and Qualifications 05.1 General Comments NRC examiners conducted regular, announced operator licensing initial examinations during the period December 1 - 5. 1997.

NRC examiners administered examinations developed by members of the Virgil C. Summer training staff, under the requirements of an NRC security agreement, in accordance with the guidelines of the Examiner Standards (ES). NUREG-1021. Interiir. Revision 8.

Eight R0 license applicants received written examinations and operating tests.

Eight candidates passed the examination.

Five of the eight candidates passed the examination but exhibited weaknesses.

Four of these five candidates demonstrated weaknesses on the written examination. One of these four candidates also demonstrated weakness on the JPM portion of the operatina test. The remaining candidate of the five also demonstrated weakness on the JPM portion of the operating test.

Candidates were considered to have passed but exhibited weakness if they received an unsatisfactory grade on any one administrative topic area, completed only 80 percent of the JPMs successfully, or received a grade of 1.8 to 2.0 on any one competency during the dynamic simulator examinations.

Candidates were considered to have passed the written examination but exhibited weakness if they receive a grade of 80 - 82 percent.

Detailed candidate performance comments have been transmitted under separate cover for management review and to allow for appropriate candidate remediation.

05.2 Pre-Examination Activities a. Scope The NRC reviewed the licensee's examination submittal using tne criteria specified for examination development contained in NUREG-1021. Interim Revision 8.

This examination represented the licensee's first attempt at developing written examinations and operating tests for the NRC's initial operator licensing process.

. b. Observations and Findinas The licensee developed the written examination, one JPM set, and four dynamic simulator scenarios, including one back-up scenario, for use during this examination. All materials with the exception of the operating test outline were submitted to the NRC on time.

NRC examiners reviewed, modified, and approved the examination pria to administration.

The NRC conducted an on-site preparation visit during the week of November 17, 1997, to review and validate the examination materials and familiarize themselves with the details required for examination administration.

Although the training staff was very responsive to the examiners' comments, significant effort was required to modify the examination materials to meet the criteria set forth in NUREG-1021 Interim Revision 8.

(1) Written Examination Development The knowledges and abilities (K/As) selected for testing on the initial sample plan submittal were not evenly distributed as required by NUREG-1021.

Three K/A category tier totals for plant systems recommended sampling no topic areas. Also, although the facility training departme.t representatives indicated the sample plan topics were chosen systematically, NRC review of the licensee's selection methodology could-not confirm all aspects of the process.

In the future, the process for licensee development of the sample plan needs to be more clear and scrutable in this regard.

The NRC examiners reviewed and validated the written examination in a , period of approximately five weeks including parts of the preparation and examination weeks.

Although the examiners found many question subject areas were of high quality, the examination contained numerous deficiencies that were similar in scope and nature to the deficiencies that have been noted at other facilities on the first attempt at developing the NRC licensing examinations. These deficiencies resulted in changes to approximately 79 questions with 51 of these-changes categorized as significant.

The following is a partial listing of some of the problems noted.

Enclosure 1 .- _ , -.

__ _ - .

(a) Approximately forty-five questions were' found to contat'1 distractors classified as' ~ specific determiners." Specific determiners-include: options which can be judged correct or incorrect without referencing the stem implausible distractors, or a correct option that differs from the distractors in style or terminology.

(b) Eight questions contained distractors which were potential additionally correct answers.

Four questions as written had potentially no correct answer.

(c) Three questions were replaced for low discriminatory value or significant overlap with other examination test items.

(d) Technical errors were noted in four questions.

(e) Approximately 29 questions were reclassified from "significantly modified" to " bank" questions.

(2) Operating Test Development The NRC reviewed and validated all portions of the operating test November 17'- 22, 1997. using the Virgil C. Summer Nuclear Station simulator and walking down inplant JPMs.

In general, the JPMs were considered acceptable for evaluation of the candidates' system-related knowledge and abilities, and at an appropriate level of di fficulty. One JPM was substantially revised due to the inaccessibility of its in-plant location (high radiation area) and minor changes were made to five other JPMs to increase their discriminatory value.

However, approximately 30 percent (8 of 28) of the Category A and B pre-scripted questions were inappropriate direct look-up or simple memory questions. The examiners considered the revised questions, rewritten by the fdcility's examination team, to be very good test items for evaluation of the candidates' -understanding of the systems' referenced K/As.

The examiners considered the facility proposed simulator scenarios marginal in discriminatory value.

Although the scenarios exercised the candidates on the minimum number of required evolutions, failures and transients as prescribed on form ES-301-5. " Transient and Event Checklist." the examiners considered the scenarios deficient with regard to analysis and problem solving events. -Adequate scenario coverage for all competencies and rating factors per Form ES-301-6.

" Competencies Checklist." such that an unsatisfactory rating. factor evaluation would result if the candidates performed poorly, was not - -apparent.

In a number of instances, coverage for the six competencies and associated 20 rating factors was improperly credited to a singular event.

For example, event FW19-2 of-proposed scenario

3 credits the BOP operator candidate with performance on all six Enclosure 1

-=- - -. - .

competency areas.

While coverage for three competency areas - Understand and Interpret Annunciators and Alarms. Comply With and Use Procedures, and Operate Control Boards - is apparent, coverage for the remaining competencies is doubtful should the candidate properly - implement the appropriate procedure actions.

The licensee worked diligently with the NRC examiners during the preparation week to resolve these concerns and produce an excellent quality product exhibiting a nigh level of discriminatory value.

c. Conclusion The NRC concluded that the facility licensee's first effort at " developing NRC initial operator licensing examinations was a valuable but difficult and resource intensive learning experience.

The examiners noted the fa * Ity training staff for their professionalism and unflagging work efforts in correcting and improving the licensing examinations.

However, the quality of the examination submittal needs to be improved for future examinations consistent with the overall quality reflected in the as-given examinations.

Greater emphasis needs 'o be placcd on the credibility and plausibility of written examination . question distractors, and the analysis and problem solving attributes of the simulator scenarios * events.

Due to the scope and-number of changes needed on the written examination, the facility and the NRC mutually agreed to postpone the administration of the written examination until December 12, 1997, to allow for an additional review and a revalidation.

05.3 Examination Results and Related Findinas. Observations. and Conclusions a. Scope The examiners reviewed the result of the written examination and - evaluated the candidates' compliance with and use of plant procedures during simulator scenarios and JPMs. The guidelines of NUREG-1021.

Forms ES-303-3 and ES-303 /. " Competency Grading Worksheets for Integrated Plant Operations." were used as a basis for the operating test evaluations.

b. Observations and Findinas-Written Examination The written examination was administered by the facility licensee on December 12, 1997, transmitted to the NRC in Rockville. Md., the next week and received December 16, 1997. The facility had no post-examination review comments but recommended that one question (#17,

5324) be deleted from the examination.

In response to a candidate's inquiry regarding this question, the proctor identified an error common to the question's stem and all answer choices. The marked-up, revised copy of the questien provided to the candidates contained the answer Enclosure 1

-- - - - . - - --.--_- -.- -. . . - .. - .

since it was inadvertently derived from the master examination that included the-answers.

This error was immediately identified by a . candidate and was then reported by the proctor to the NRC in Region II.

The NRC's post-examination review of the written examination results identified nine_ questions that 50 percent or more of the candidates answered incorrectly.

These are considered potential generic weaknesses , and are being provided to the training staff for consideration and implementation into their Systematic Approach to Training based program: Question Number Knowledae Weakness Area 01 (5303) Protective action sequence for a large steam line break in the Turbine Building.

04 (5101) The preferred method for tripping the reactor following a control room evacuation.

11 (5207) Operation of the "A" Service Water System Train following a loss of offsite power to emergency bus IDA with the "A" Diesel Generator responding as designed.

12 (5345) Status of the block / reset circuitry for the safety injection and phase A containment isolation logic systems following a manual safety injection with one reactor trip breaker closed.

19 (5326) Status of the operating systems providing cooling to the Reactor Building with a Loss of Coolant Accident and several emergency system failures.

21 (5214) Reason for E0P-15.0. Response to Loss of Secondary Heat Sink, directing operator placement of the Feedwater Isolation Valve Switches in the Bypass position.

40 (5346) Preferred method for refilling the pressurizer per E0P-4.2, SGTR with Loss of Reactor Coolant: Subcooled Recovery Desired, with a concurrent grid disturbance and loss of all three Reactor Coolant Pumps.

45 (5356) Method for refilling the pressurizer per E0P-2.1, Post-LOCA Cooldown and Depressurization.

Enclosure 1 . - .

- .

58 (5131) Required operator actions for failure to achieve criticality by the desired estimated critical position during a reactor startup.

Oneratina Test The operating test was administered during the period of December 1 - 5.

1997.

Based on post-examination review and discussion with the facility training staff. the !!RC determined JPM steps #515 and #S26 were not critical for accomplishment of the task standards in JPMs #JPPF-144 and

JPSF-171. respectively.

The examiners' post -examination review of the operating tests identified the following generic strength and weaknesses: All of the candidates routinely adhered to and practiced the

principles of the STAR program during the performance of operator tasks and actions.

Five candidates did not know the bases for the Minimum

Temperature for Criticality (question #ADMA1B).

Four candidates could not correctly determine the dose limit and . stay time from EPP-20 to protect valuable property (question

ADMA38).

Three candidates could not correctly calculate the Reactor Vessel . Head Venting time for given plant conditions following a SBLOCA (question #JPF-144A1).

Three candidates properly identified isolation valve failures for . two different JPMs but did not act to close the valves (JPM

JPSF-137 & #JPSF-057).

The wording of E0P -1.0. Alternative " Action step #15 (b) " Verify Phase B isolation by ensurina - may have contributed to one candidate's failure to close the failed isolation valve.

Additionally, in several other instances, the candidates recognized degraded system and component operation and reported the status and indications to the SR0 but failed to take or recommend any action to addiess the problem.

For example, in scenario #6A. one candidate recognized the failure of the DG governor, reported to the SRO. and directed local operators to observe the DG locally.

However, although the DG load oscillations increased in magnitude over a period of five minutes, the candidate took no further action nor made any recommendation for action to the SRO. The DG automatically tripped on overspeed.

In several instances during the dynamic simulator and control . room systems operating examinations, the candidates demonstrated a lack of awareness of plant conditions and available control Enclosure 1

- - - .

room indications which delayed the event diagnosis process.

For example, in scenario #6A. event MS21-2. one candidate failed to recognize that there was indicated steam flow on the 'B' main steam line with the MSIV closed. This impeded the identification of the safety valve failure.

In two other instances, the candidates failed to identify a second dropped rod and as a result did not trip the reactor as required (JPM #JPS-168).

Candidate communicat. ions during the dynamic simulator

examinations were considered marginal.

The candidates riid not always complete the third leg of the 3-way communications process and in several instances did not always report communications received from outside the control room via the radio to the SRO.

Also, in some cases only one of the R0 candidates would acknowledge the SR0's announcement of an E0P transition, c. [ An.c] psi g n The examiners concluded that candidate performance on the written examination and operating tests was satisfactory but the number of weaknesses was considered somewhat higher than average.

V. Manaaement Meetinos X1, Exit Meeting Summary At the conclusion of the site visit, the examiners met with representatives of the plant staff listed on the following page to discuss the results of the examinations. The licensee's management representatives prcijded no dissenting comments, flo proprietary information was identified.

These observations do not constitute audit or inspection findings and are not, without further verification and review, indicative of noncompliance with 10 CFR 55.45(b).

These observations do not affect NRC certification or approval of the simulation facility other than to provide information that may be used in future evaluations.

No licensee action is required in response to these ' observations.

While conducting the simulator portion of the operating tests, the following deficiencies were observed (if none, so state): During performance of scenario #1 (no 3A). radiation monitor alarms

were spuriously received.

These alarms were not related to the scenario.

During the second run of scenario #1 (no. 3A), the simulator computer . locked-up.

, . . , ..i Modified questiion from:~527 by.Ihanging "IR trip" to PR trip" because' examinee would have had to calculate a reactivity balance from memory to determine that PWR RELIEFS will turn power prior to trip.

a.

Incorrect since initial conditions are too far from setpoint for Tavg penalty to bring setpoint down far enough to trip (Actual AT is low at 2% power) before S/G safeties stop transient.

.

_.. _ - . . , . . . . . , 4. '3 b.

Incorrect.

Power defect will balance Tavg

Must recognize that initial startup out of ' Refueling Outage 10 has'a positive MTC.

Also inust ' ' determine that a loss of C-9 will cause a loss of I . ' steam dumps, which will heatup the RCS.

Correct";i RequEres traibee to analy::e symptoms, apply Note 1, EOP-13.0, then determine appropriate response.

Note 1 applies to an Immediate Operator Action in EOP-13.0, which should be performed from memory.

Manual rod speed is 48 spm; anything faster is acceptable.

Also requires examinee to apply knowledge that prior to adjusting N44, rods must be in MAN.
