'
During the period of November 4-7,1997, the NRC administered initial exams to eight employees of your company who had applied for licenses to operate the James A.
FitzPatrick Nuclear Power Plant. At the conclusion of the examinations, the prelimi, nary findings were discussed with Mr. Topley and members of your staff.
All eight applicants passed the exams. All applicants were well prepared for the examination.
Your staff developed the initial examinations. However, the quality of your staff's initial input did not meet our expectation. Based on the interaction between the chief examiner and your staff, an acceptable examination was eventually developed and subsequently administered. We hope that the lessons learned will be applied during future examination development efforts.
An unresolved item was identified related to a change made to your Emergency Operating Procedures.
In accordance with 10 CFR 2.700 of the NRC's " Rules of Practice," a copy of this letter and its enclosures will be placed in the NRC Public Document Room (PDR).

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 James A. FitzPatrick (JAF) Nuclear Power Plant.
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 defir.ed in NUREG 1021. However the JAF training staff responded to the NRC comments on the proposed examination and developed a final examination that was acceptable.
An unresolver' item was identified related to a change made to the Emergency Operating Procedures regarding initiation of isolations that should have occurred but did not.
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 an alternate path task related to the refueling interlock test.

Reoort Details 05.1 Operator initial Exams a. Scone 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 James 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.
b. Observations and Findinas The results of the initial examinations are summarized below:
I SRO RO Pass / Fail Written 4/O 4/O 8/O
' Operating 4/0 4/O 8/0 l Overall 4/O 4/0 8/O 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 process.
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 staff.
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 proposed examination. I
- Simplistic written, JPM and admin questions
-
Poor written question 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 writt'en at the SRO level
-
JPM questions written as direct look up rather than "open reference" use
-
Inadequate operator actions in the proposed simulator scenarios
- Specification of scenario critical tasks
-
Inadequate malfunctions to assess each operator in the competency evaluation ,
The NRC examination team held an examination preparation visit the week of September 20,1997. As a result of the NRC and JAF staff interaction, an acceptable examination was developed and administered.
JAF staff administered the written examinations on November 3,1997. The NRC examiners administered the operating examinations in the period of November 4-7,1997.
By letter, dated Nover%r 12,1997, JAF staff provided the grading of. o written examination and identh.1: 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 staff.
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 test.
During the operating test, the following items were significant and consistent positive observations.
P&lD, electrical, and logic prints were effectively used by the applicants.
Toimwork within the crews was very good.
Communication within the crews was very good. Crew briefings were concise, timely, and appropriate. The applicants were very poised.
. . -
.. . .... - . . . .
.
. . . .
.
l
Procedures, including alarm response procedures, were effectively used during the scenarios.
Effective use of peer checking.
c. Conclusions The applicants were well prepared for the examination, and as a result,8 of 8 applicants passed the examinations and were subsequently issued licenses.
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 developing an acceptable examination. !
03.1 Emeraency Operatina Procedures (EOPs)
a. Scope The examiner reviewed the change to EOPs which changed the Emergency Procedure Guideline (EPG) step RC/L-1 from " Initiate each of the following which should have initiated but did not" to " Verify initiation of".
b. 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 changed 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 JAF " 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 not.
The EOP pr.aedure 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 addressed.
c. 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 j change documentation should be reassessed for completeness and adequacy. In 1 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)
l'
E.8 Review of UFSAR Commitments j A recent discovery of a licensee operating their facility in a mentar contrary to the updated final safety analysis report (UFSAR) description highlighted the need for a i special focused review that compares plant practices, procedures and/or parameters )
to the UFSAR descriptions. While performing the examination activities discussed l in this report, the examiner reviewed portions of the UFSAR that related to a main j steam line break accident examination question. The selected examination question -(
reviewed was consistent with the UFSAR. .

ATTACHMENT 3 JAF COMMENTS ON WRITTEN EXAMINATION
. r RO 009 SRO 009 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 balancing the examination di. tractors. 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 open.
l Distractor C is incorrect because the SRV tailpiece would rise to approximately 380
!
degrees if the valve were open.
Distractor D is incorrect because the EPIC alarm RESET condition indicates that the high noise level condition associated with an open SRV has cleared.
I The key was changed from D to B to correct this error.

l STANDBY GAS TREATMENT SYSTEM * OP-20 i B. SYSTEM DESCRIPTION The Standby Gas Treatment System includes two identical filter tra',ns. Each filter train is a full capacity system -
that has the ability to maintain reactor building to i
'
atmosphere differential pressure more negative than negative O.25 inches water gauge.
Each filter train includes the.following:
- Demister: Removes entrained moisture, and in conjunction with the air heater, maintains humiolty less than 70% at the inlet to the charcoal filter.
- 39 KW Electric Air Heater: Maintains humidity less than 70% at the inlet to the charcoal filter.
- Prefilter: Removes particles.
- High Ef ficiency Particulate Absolute Pre-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.
- 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 *iO% humidity. Charcoal filter material is iodide or T2DA impregnated activated carbon.
- High Efficiency Particulate Absciute Af^er-Filter (HEPA) :
Designed to be capable of removir.g 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 stack.

Rev. No. 22 Page 5 of 45
STANDBY GAS TREATMENT SYSTEM * OP-20 Each filter train can take suction from one or more of the following suction supplies:
- Reactor Building above 369' elevation
- Reactor Building below 369' elevation
- Drywell vent connections
- Torus vent connections
- HPCI gland seal exhauster
- Main Steam Leakage Collection System
- Auxiliary Gas Treatment System Standby gas treatment trains are cross-tied at the fan suctions to allow drawing cool air over the charcoal filter of the inactive train to remove decay heat.
T'he Standby Gas Treatment System auto-initiates when any of the following conditions occur:
- Reactor Building Ventilation above 369' elevation exhaust duct radiation high-high: PCIS logic A sensors start A train; PCIS logic B sensors start B train
.
- Reactor Building Ventilation below 369' elevation exhaust duct radiation high-high: PCIS logic A sensors start A train; PCIS logic B sensors start B train
- Drywell pressure high (2.7 psig increasing) : Both trains start
- RPV water level low (177 inches decreasing) : PCIS logic A sensors start A train; PCIS logic B sensors start B train
-
- HPCI auto-initiation: Both trains start The Standby Gas Treatment System can be manually placed in service from panel 09-75 in the Control Room.

SRO 647 During the administration of the examination, a typographical error was noted in that distractors A and C were the identical. Distractor C was changed from:
.
Turbine Govemor Valve open; Turbine Steam Inlet Isolation Valve closed.
to:
Turbine Governor Valve open; Turbine Steam Inlet Isolation Valve open.
This corrected the typographical error but necessitated a key change for the SRO exam from C to A. The determination to change distractor C vice distractor A was based on the fact that some candidates had already recognized A to be a conect answer and marked their answer sheets to reflect their choice.
.
.
.
RO 061 SRO O61 During the post-examination review, it was discovered that there were two correct answers given for the question.
The rod drift indication however is not referenced as a symptom of an uncoupled control rod in the applicable procedure, AOP-25, UNCOUPLED CONTROL ROD. 'Ihat procedure states the symptom:
An overtravel alarm is received during a coupling check of control rod."
Both the ROD DRIFT and ROD OVERTRAVEL' annunciators will alarm if the respective condition exists for any of the 137 control rods. Each of the control rods also has an individual rod drift light on the full core display. There is actually no " Individual" 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 answer.
The answer key was changed to reflect either A or B as a correct answer.
