EXECUTIVE SUMMARY Byron Generating Station, Units 1 & 2 NRC Examination Reports No. 50-454/96301; 50-455/96301 A licensee developed and NRC approved initial operator licensing examination at the senior l reactor operator (SRO) level was administered to ten applicants. This examination process '
incorporated a one week on-site period for administration of the operating examination and ;
the supporting NRC review and approval effort. In addition, the written examination was l reviewed by and received NRC approval for administration by the license l i
During this examination, a loss of examination material control was identified by the '
licensee and was in violation of NRC requirements as stated in 10 CFR 55.49, " Integrity of Examinations and Tests." However, as described in the enclosed examination report l (section 05.1), the violation is not being cited because the criteria specified in Section '
Vll.B.1 of the NRC Enforcement Policy was satisfie Results: Eight applicants passed all portions of their respective examinations and were issued senior reactor operator licenses. Two applicants failed one or more portions of their ,
respective examinations and were denied an operating licens l l
Summarv: The following is a summary of performance:
e A loss of examination material control required the generation of replacement examination material and resulted in a substantial delay in examination administration. (Section 05.1)
e Licensee validation of examination materiallacked comprehensive review as evident by errors detected during examination administration. (Section 05.2)
e A generic knowledge deficiency regarding independent verification requirements was recorded while performing a clearance tagout review. (Section 05.3)
e The applicants' effective use of communications during dynamic scenarios enhanced good teamwork. (Section 05.5)

Reoort Details i i
1. Ooerations 05 Operator Training and Qualification j 0 General Comments j The licensee volunteered to participate in a pilot process in which the NRC initial ;
operator license examination consisting of operating and written test sections were '
,
prepared by the licensee, then reviewed and approved by the NRC. The operating i test was administered by the NRC and consisted of two areas: i e A walkthrough section covering two categories which focused on administrative topics and job performance tasks related to control room and inplant system e A performance-based section focused on dynamic, integrated plant !
conditions evaluated during dynamic simulator scenario sets.
.
The written test was administered by the licensee and consisted of 100 multiple- i choice questions focusing on a broad spectrum of plant systems' design and

operatio ;
J 05.2 Licensee Developed Examination Material and Security 1 Examination Scone (NUREG-1021 & GL-95-06)
Examination development guidance and security measures were prescribed by NUREG 1021, " Operator Licensing Examiner Standards," Revision 7, and
-
superseded in part by Interim Pilot Examination Guidance provided in Generic Letter (GL) 95 06, " Changes in the Operator Licensing Program."
" Observations and Findinas l
l Security Measures (1)
During the initial development phase, the licensee became aware on Monday, July 29,1996, that the examination development room's secure door had been left unlocked for some 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> between July 26,1996 and July 29,1996. The loss of examination material control was reported to the
-
NRC on Tuesday, July 30,1996. Also, the NRC was informed of a similar but minor occurrence on Thursday, July 25,1996. The examination development room had been left unattended for approximately 2 minutes with the secure door locked but aja i
. i
,
The examination development room contained stand-alone computers which were password protected and a lockable file cabinet used for storage of examination material. This second level of security was deemed appropriate by the licensee until the NRC examiners questioned the security risk of routinely storing the lockable file cabinet's key within the examination development room. This key had been located in the examination development room during both occurrence The licensee took prompt action to submit a Problem Identification Form (PIF) addressing both occurrences and initiate short-term corrective actions (such as: replacement of the secure door key-lock with an improved security mechanism, and permanent removal of the lockable file cabinet's i key from the room). Additional long term corrective actions were proposed l to strengthen existing security measures. Based upon NRC concerns, the j licensee proposed replacing all of the potentially compromised examination material with newly developed item Following a review of this occurrence and the licensee's corrective actio the NRC concluded that the examination material compromise could have been prevented or minimized based upon corrective actions take ;
Additionally, the replacement of all compromised examination material was j deemed appropriate. Because of the added burden to develop replacement examination material, the NRC agreed to delay the operating test by three weeks and the written test by six week ,
l Failure to maintain control of examination material was a violation of 10 CFR I 55.49, Integrity of Examinations and Tests, which states in part that licensees shall not engage in any activity that compromises the integrity of 1 any test required by this part. This licensee-identified and corrected violation l I
is being treated a Non-Cited Violation, consistent with Section Vll.B.1 of the NRC Enforcement Poliev (50-454/96301-01(DRS)).
(2) Develonment of Examination Material The licensee provided an integrated examination outline for NRC review and approval some 60 days in advance as required. The outline content was !
acceptable and met the requirements specified in NUREG-1021 to begin l examination developmen The replacement examination material was delivered to the NRC some 30 days prior to examination administration as required. In general, the replacement material was consistent with the guidance in NUREG 1021 and GL-95-06. Some twenty percent of the written examination questions and JPM tasks / questions were revised or replaced to enhance the examination validity and/or level of difficult The following information is provided for evaluation by the licensee via their SAT based training program. No response is require !
.
.
(a) Written Examination The written test was considered technically accurate with two exceptions as evident by the post examination comments. In order to clarify technically incorrect information, the licensee required a change to one question's stem while another question required a change to the wording in one of its distractors. These changes were considered appropriate but should have been identified during the validation revie The following are examples of selected test items which contributed to a reduced level of difficulty requiring NRC enhancement:
- Selected distractors were implausible and could be easily discarde e Selected distractors were not related to the intent of the question or could be easily eliminated (such as exact opposite responses " decrease versus increase").
e r; elected distractors referenced specific information in the stem of the question and reflected the most correct choic e Use of selected plant conditions or events in the stem of some questions reduced the evaluation focus from complex analysis to simple comprehensio The licensee incorporated the NRC review comments into a revised version of the examination which was approved for administratio (b) Walkthrouah The walkthrough test was considered technically accurate requiring a few minor changes within selected tasks and the replacement of one task to enhance the examination qualit (c) Dynamic Simulator Scenarios The integrated operating simulator test was considered technically accurate required only a few minor changes to enhance selected scenario event .3 Ooerational Examination Validation Examination Scoce (NUREG-1021)
Using NUREG-1021, Operator Licensing Examiner Standards, Revision 7, the examination team revised and validated the operational examination material
.
,
consisting of walkthrough and dynamic scenario portions. This involved extensive use of the plant specific simulator and an inplant tou Observations and Findinos The replacement operational examination material was content validated in accordance with guidance contained in NUREG-1021. The NRC examiners verified that each portion of the operational examination was valid and ready for administration.
1 During examination administration, the NRC examiners identified a number of minor
'
validation deficiencies. However, one of these was deemed significant enough to potentially impact the applicants' performance requiring prompt NRC intervention to ensure exam validity was maintained. The following are selected examples of improper attention-to-detail during validation:
i e The lack of a Master Out-Of-Service Card for the perfoimence of an i
administrative tagout review was questioned by the apolicants. Tiiis card
- should have been included with a normal package review bui was not identified during the validation process as being necessar e JPM NRC-9 (Locally Close RWST to RH Suction Valve) contained an evaluator cue to be given to the applicants which directed them to perform an operator action on valve "2RH8812." A discrepancy was identified by i the applicants during the examination administration. Valve 2RH8812 does
,
not exist. The valve nomenclature should have been "2Sl8812."
e Dynamic Scenario 2-3, Event E (RCP Seal Failure following a loss of I
Instrument Bus 114), resulted in a loss of power to selected meters and chart recorders on the main control board. During the validation process, the licensee failed to identify that a loss of Bus 114 would result in a complete loss of meter / recorder indication for the failed RCP pump seal. The required main control board indication necessary to identify the event in progress was not available as expected. The NRC examiners were required to provide appropriate indication by communicating the necessary data through the simulator operato .4 Ooerational Examination Administration Examination Scooe (NUREG-1021)
Using NUREG-1021, Operator Licensing Examiner Standards, Revision 7, the examiners administered an operational examination consisting of a job performance (JPM) walkthrough section and a dynamic scenario set section to each applican This involved extensive use of the plant specific simulator to perform dynamic scenarios and a section of the JPM walkthrough. A separate section of the JPM walkthrough was simulated during an inplant tou .
. Observations and Findinas in general, the applicants demonstrated an above average level of skill while operation the licensee's plant specific simulator facility. The applicants' effective useci eway communication and crew mini-briefings during the dynamic sce' . contributed to good teamwor Onu administrative section required the applicants to perform a review of an out-of-service tagout prior to return to service. Six of the ten applicants failed to determine that one of the eight components had been improperly verified to be in its required position. Each component was required to be acknowledged as being in its correct position by a second, independent verifier. The NRC examiners informed the licensee of this knowledge deficiency and were informed by the licensee that prompt corrective actions were being formulate Simulator operator support during the dynamic scenarios and simulator JPMs was mixed. The following concerns regarding simulator operator support were noted:
e During one scenario, the simulator operator failed to place the simulator in RUN following a turnover until prompted by one of the board operators. This caused a short delay in scenario implementation but did not impact the applicants' performanc e During one scenario, the simulator operator caused a premature reactor trip during an attempt to remove a previously set malfunction per NRC's reques This resulted in a small delay to allow a reset of the simulator but did not impact the applicants' performanc e During JPM setup on the RM-11 console, the simulator operator reversed the HIGH and ALERT setpoints on one JPM. However, this error had no impact on the applicant's performance and was corrected prior to performance by another applican The licensee's operational and support staff provided quick, responsive assistance to the NRC examiners' needs ensuring minimal delays in the examination process during simulator operations and inplant tours. A licensed reactor operator's performance in the surrogate role was appropriate and met NRC expectation .5 Simulator Fidelity Examination Scone (NUREG-1021)
Using NUREG-1021, Operator Licensing Examiner Standards, Revision 7, the examiners observed the performance of the plant specific simulator during job performance (JPM) walkthrough and dynamic scenario sets. This fidelity review ]
was conducted in relation to simulation tasks performed on the plant specific i simulator during the examination proces l
.
. Observations and Findinas The plant specific simulator was able to accurately mimic plant parameters during a variety of malfunctions and plant conditions. However, during the performance of selected dynamic scenarios and JPM tasks, the examiners observed three separate equipment fidelity occurrences which are described in Enclosure 2, Simulation Facility Repor .6 Conclusions on Ooerator Trainina and Qualification i The licensee developed examination material met the examiners' standards as j outlined in NUREG-1021 as superseded by GL-95-06. The written examination portion was evaluated as having a low discrimination value requiring more than average NRC effort to enhance its quality. The walkthrough and dynamic scenario )
examination portions were evaluated as having a medium discrimination value !
requiring less than average NRC effort to modify the examination materials to meet I
'
the standard The applicants appeared well prepared for the examination and their overall performance was good. This was most evident during the dynamic simulator evaluations as demonstrated through effective use of three-way communications and crew mini-briefs during routine as well as abnormal plant condition V. Manaaement Meetinas X1 Exit Meetino Summarv ;
The chief examiner presented the examination team's observations and findings to members of the licensee's management on October 17,1996. The licensee acknowledged the findings presented. No proprietary information was identified during the examination or at the exit meetin .

- A radiochemical analysis for E shall consist of the quantitative i
measurement of the specific activity for each radionuclide, except for
- radionuclides with half-lives less than 10 minutes and all radiciodines,
- which is identified in the reactor coolant. The specific activities for these individual radionuclides shall be used in the determination of E
