_ _ _ _ _ _ _ _ _ _ EXAMINATION SUMMARY - Examination Report 50 333/97 09 (OL) Initial exams were administered to four senior reactor operator (SRO) instant applicants and four reactor operator-(RO) applicants during the period of November 4 7,1997, at the Jarnes A. FitzPatrick (JAF) Nuclear Power Plan OPERATIONS All eight applicants passed the exam. All applicants were well prepared for the examination. The JAF training staff and a contractor developed the examination. .The quality of the initial submittal was not at the level that met NRC expectations as defined in NUREG 1021. However the JAF training staff responded to the NRC comments on the proposed examination and developed a fina' examination that was acceptabl ' An unresolved item was identified related to a change made to the Emergency Operating Procedures regarding initiation of isolations that should have occurred but did no On the operating test, the examiners noted very good performance regarding team work, use of prints, communication, procedure use, and peer checking. Also, the examiners noted weak performance related to a1 alternate path task related to the refueling interlock test, ii .

Reoort Details 05.1 Operator Initial Exams $1QQg, The examiners administered initial examinations to four RO and four SRO instant applicants in accordance with NUREG 1021, " Examiner Standards," Interim Revision 8. The examinations were prepared by Jarr.es A. FitzPatrick (JAF) staff and were approved by the NRC JAF staff administered and graded the written examination. The NRC administered and graded the operating test and concurred with the JAF staff grading of the written examination, Observations and Findinas The results of the initial examinations are summarized below: ' l SRO RO Pass / Fail Written 4/0 4/0 8/0 Operating 4/0 4/0 8/0 Overall 4/0 4/0 8/0 The examinations were prepared by JAF staff. The JAF staff involved with the development of these examinations signed security agreements to ensure the integrity of the initial examination proces . JAF staff submitted their proposed sample plan on August 27,1997. The NRC Chief examiner made minor changes to the submitted sample plan which were made by the JAF staf The JAF proposed SRO and RO written examinations were submitted for NRC approval on September 25,1997, and the operating tests the following week as agreed by the Chief Examiner. The JAF initial submitted examination was not an examination capable of discriminating between acceptable and unacceptable license candidates and required modification to meet NRC Examiner Standards. The following is a summary of the problems noted with the prope, sed examinatio Simplistic written, JPM and admin questions
-
Poor written questiun distractors which were easily eliminated
-
Written questions which did not correlate with the assigned K/A
-
Awkwardly worded written and JPM questions
-
Written and JPM questions that did not solicit the answer in the answer key
- . . _ _ _ . _ _ - _ _ - _ _ - _ - _ _ _ _ _ _ _ _ _ _ _ _
- Double jeopardy questions - Lack of balance in the written distractors -- More than one correct answer - Inadequate cues for in-plant JPMs - JPM and admin questions not written at the SRO level - JPM questions writtnn as direct look up rather than "open reference" use - Inadequate operator actions in the proposed simulator scenarios - Sperification of scenario critical task 4 - Inadequate malfunctions to assess each operator in the competency evaluation The NRC examination team held an examinav e > reparation visit the week of September 20,1997. As a result of the NRC and JAF staff interaction, an acceptable examination was developed and administere JAF staff administered the written examinations on November 3,1997. The NRC examiners administered the operating examinations in the period of
, November 4 7,199 By letter, dated November 12,1997, JAF staff provided the grading of the written examination and identified comments on five questions. A copy of the JAF letter is contained in Attachment 3. The NRC accepted the JAF comments on the written examination as described in Attachment 4. The examiners reviewed the grading of the written examinations and concurred with the grading by JAF staf During the walkthrough portion of the operating test, the SRO instant applicants performed poorly in the following task: Alternate path task related to the refueling interlock tes During the operating test, the following items were significant and consistent positive observation P&lD, electrical, and logic prints were effectively used by the applicant Teamwork within the crews was very goo Communication within the crews was very good. Crew briefings were concise, timely, and appropriate. The applicants were very poise Procedures, including alarm response procedures, were effectively used during the scenario Effective use of peer checking, Conclusions The applicants were well prepared for the examination, and as a result,8 of 8 applicants passed the examinations and were subsequently issued license JAF staff did not have a complete understanding of the NRC expectations in the development of their proposed initial examination. Significant interactions between ' the NRC and JAF staff were required to develop an examination that was consistent with the NRC Examiner Standards, in the end, JAF staff were successful in Jeveloping an acceptable examination.
03.1 Emeraency Operatina Procedures (EOPsl Scope The examiner reviewed the change to EOPs which changed the Emergency Procedure Guideline (EPG) step HC,,L-1 from " Initiate each of the following which should have initiated but did not" to " Verify initiation of". Observations and Findinas During the examination the examiners noted that the applicants did not always
" Verify initiation of" during the execution of the EOPs. The examiners noted that the EOPs were revised to change the step as a concurrent step rather than a series step and also " Initiate" was chenged to " Verify initiations".
At JAF, in accordance with AP-02.01 " verify initiation" meant "to observe that the associated activities have been performed or that the expected conditions or characteristics exist." This was not the same as " Initiate each of the following which should have but did not". AT JA.F " verify" was performed on a concurrent, when available basis by the ROs informing the SRO what actions should have initiated but did not. The SRO was allowed to decide as to whether to initiate those actions. At JAF " ensure" was used to mean initiate each of the following which should have initiated but did no The EOP procedure change, dated December 6,1996, which made the change and the resulting plant specific technical guide (PSTG) indicated that this was plant specific terminology and did not specifically identify whether the wording change was meant to be identical in interpretation. In addition,the change from series to concurrent execution of initiate isolations was not specifically addresse Conclusion
- An unresolved item was identified for JAF to provide an assessment of whether "
Verify isolations" was meant to be equivalent to " initiate each of the following which should have but did not". 'If this was not the case, then the procedure i change documentation _should be reassessed for completeness and adequacy. In addition the adequacy of the change from series to concurrent, when available execution should be documented.- This is unresolved item (50 333/97 09-01)- Review of UFSAR Commitmerits A recent discovery ~of a licensee operating their facility in a manner contrary to the updated final safety analysis report (UFSAR) description highlighted the need for a special focused review that compares plant practices, procedures and/or parameters to the UFSAR descriptions. While performing the examination activities discusssd l In this report, the examiner reviewed portions of :he UFSAR that related to a main steam line break accident examination question. The selected examination question reviewed was consistent with the UFSA V. Manaaement Meetinas X1 Exit Meeting Summary At the conclusion of the examination, the examiners discussed their observations of the examination process with members of JAF management. The examinations noted that no simulator fidelity concerns had been observed or identified. JAF management acknowledged the examiner observations.
The JAF personnel present at the exit included the following: P. Brozenich, Operations Manager R. Locey, Training Manager J. Morris, initial Program Administrator J.

-:SRO 909 During the post-examination review, it was discovered that the key contained an incorrect
- answer, D vice the correct answer, B. This was a typographical error that occurred while - t
*
balancing the examination distractors. The first submittal (attached) indicated the answer ' correctly. -
.
:
'
Distractor A is incorrect because the red light on indicates that the pilot solenoid is energized, not that the main valve is ope ;
'
Distractor C is incorrect because the SRV. tailpiece would rise to approximately 380
- degrees if the valve were ope 'i Distractor D is incorrect because the EPIC alarm RESET condition indicates that the high noise level condition associated with an open SRV has cleared.- !
The key was changed from D to B to correct this error.

o- . RO 031 SRO O31 This question was deleted from the examination. During the post-examination review it was determined that the question had no correct answer. The limits stated form an envelope that bounds the operation of the system and no direction exists to violate one limit at the expense of another, a. OP 20, STANDBY GAS TREATMENT SYSTEM, directs: IF reactor building difTerential pressure is less negative than -0.25 inches water, TIIEN ensure that SGT Train A (B) is in service per Subsection D.l(2).' No direction is given allowing this limit to be violated to meet other limits, b. OP-20, STANDBY GAS TREATMENT SYSTEM, directs if the high temperature annunciator is received then the affected train is shutdown and cooling flow for the charcoal filters established using the other train.2 No direction is given allowing this limit to be violated to meet other limits, c. OP-20, STANDBY GAS TREATMENT SYSTEM, directs: Ensure flow rate is 3000 to 6000 scfm on SGT FLOW 01 125FI 106A(B).3 No direction is given allowing this limit to be violated to meet other limit ' OP-20, STANDBY GAS TREATMENT SYSTEM, revision 22, steps D.I.6 on pg.

The Standby: Gas Treatment 1 System. includes two identical-filter trains. Each filter train is a full _ capacity system thet has the ability to maintain reactor building to atmosphere differential' pressure more negative than negative 0.25 inches water gaug ~Each filter train includes the following:-
-* Decister: Removes entrained moisture, and in conjunction with the air heater, maintains humidity less than 70% at the inlet to the charcoal filte ; * 39 KW Electric Air Heater: Maintains humidity less than 70% at the inlet to the charcoal-filte ' * Prefilter: Removes particle * High Efficiency Particulate Absolute Pre-Filter (HEPA) :
Designed to be capable of removing at least 99.97% of the O'.3 micron particles which impinge on the filter, however i credit is only taken for 90% removal capabilit e Activated Charcoal Filter: Removes in excess of 95% of the iodine in the air stream, with 10% of the iodine in the form of methyl iodide, with air entering the charcoal
- filter at less than 70% humidity. Charcoal filter material is iodide or TEDA impregnated activated carbo * High Efficiency Particulate Absolute After-Filter (HEPA) :
Designed to be capable of removing at least 99.97% of the 0.3 micron particles which impinge on the filter, however credit is only taken for 90% removal capability.
- * Fan: Provides the differential pressure to draw gases through-the train for treatment. The fan discharges to the stac :

STANDBY GAS TREATMENT SYSTEM * OP-20 Precautions C.2.1- Reactor-building ventilation _shall be isolated before performing any of-the following activitie This action is necessary to comply with the requirements of safetyLevaluation JAF-SE-96-071:
* Puel handling * Core alterations * Movement of heavy loads over the spent fuel pool or open reactor cavity * Placing RX MODE switch in START & HOT STBY, without Primary Containment Integrity in effect C. During normal operation, 27MOV-120 (containment exhaust to standby gas treatment isol valve) shall remain closed when primary containment is required per Tech Spec 4.7. C. Operating a SGT train with the charcoal filters installed to vent paint fumes, welding fumes, or smoke could damage the charcoal filter. Guidelines to prevent possible charcoal filter damage from paint fumes are as follows: * Painting shall stop during periods of SGT operatio * Painting shall stop whenever Reactor Building Ventilation is isolated, unless SGT will not be required for 24 hours following the completion of paintin * SGT should not be run for at least 30 minutes following the completion of paintin * :If a SGT run is desired within 8 hours following . painting, Reactor Building Ventilation should not be isolated until the end of the SGT ru * SGT runs are kept as short as possible within 8 hours following paintin C. To prevent plugging of the spray nozzles from debrir caused by rust or corrosion, the fire protection water supply spray header between 76FCV-107A/B and the spray nozzles shall be drained following-system actuatio ,

J SRO 0471 l During the administration of the examination, a typographical errorfwas note 41 in that - , l ' distractors A and C were the identical.' Disanctor C was changed from: y -Turbine Governor Valve open; Turbine Steam lnlet Isolation Valve closed,
-
r to:
, Turbine Governor Valve open; Turbine Steam Inlet Isolation Valve ope . ,
This corrected the typographical error but necessitated a key change for the SRO exam from C to A. The determination to change distrac'or C vice distractor A was based on the .
~ - fact that some candidates had already recognized A to be a correct answer and marked
_
-their answer sheets to reflect their choice.

Rod Overtravel alarm as the question asks nor is there an " individual" Rod Drift alarm (there are however, individual rod drift lights). This ambiguity apparently led the candidates to associate individual in the sense of "an alarm caused by moving an individual rod." That perspective, coupled with the procedural symptom makes B also a correct answe The answer key was changed to reflect either A or B as a correct answe .
