SUBJECT: JOSEPH M. FARLEY NUCLEAR PLANT - NRC OPERATOR LICENSE

EXAMINATION REPORT 05000348/2020301 and 05000364/2020301

Dear Mr. Kharrl:

Due to the national pandemic emergency, administration of the operating test and written

examination was delayed from the dates identified in the corporate notification letter

(ML19219A218). The written examination was administered by your staff on July 31, 2020.

During the period August 24 - 28, 2020, the Nuclear Regulatory Commission (NRC)

administered operating tests to employees of your company who had applied for licenses to

operate the Joseph M. Farley Nuclear Plant. At the conclusion of the tests, the examiners

discussed preliminary findings related to the operating tests with those members of your staff

identified in the enclosed report.

Seven Reactor Operator (RO) and six Senior Reactor Operator (SRO) applicants passed both

the operating test and written examination. One RO retake applicant, who was granted an

excusal from the operating test, passed the written examination. Two SRO applicants, whose

applications were subsequently withdrawn before the operating test was administered, failed the

written examination. There was one post-administration comment concerning the written

examination and three post-administration comments concerning the operating test. These

comments, and the NRC resolution of these comments, are summarized in Enclosure 2. A

Simulator Fidelity Report is included in this report as Enclosure 3.

The operating test outlines and the written examination were developed by the NRC. All

examination changes agreed upon between the NRC and your staff were made according to

NUREG-1021, Operator Licensing Examination Standards for Power Reactors, Revision 11.

The initial operating test, written RO examination, and written SRO examination met the quality

guidelines contained in NUREG-1021.

SUMMARY

ER 05000348/2020301, 05000364/2020301; July 31, 2020 & August 24 - 28, 2020; Joseph M.

Farley Nuclear Plant; Operator License Examinations.

Due to the national pandemic emergency, administration of the operating test and written

examination was delayed from the dates identified in the corporate notification letter

(ML19219A218).

Nuclear Regulatory Commission (NRC) examiners conducted an initial examination in

accordance with the guidelines in Revision 11, of NUREG-1021, "Operator Licensing

Examination Standards for Power Reactors." This examination implemented the operator

licensing requirements identified in 10 CFR §55.41, §55.43, and §55.45, as applicable.

The operating test outlines were developed by the NRC and the written examination was

developed by the NRC. The initial operating test, written RO examination, and written SRO

examination met the quality guidelines contained in NUREG-1021.

Members of the Joseph M. Farley Nuclear Plant training staff administered the written

examination on July 31, 2020. The NRC administered the operating tests during the period

August 24 - 28, 2020. Seven Reactor Operator (RO) and six Senior Reactor Operator (SRO)

applicants passed both the operating test and written examination; one RO retake applicant,

who was granted an excusal from the operating test, also passed the written examination.

Fourteen applicants were issued licenses commensurate with the level of examination

administered.

There were four post-examination comments.

No findings were identified.

REPORT DETAILS

4. OTHER ACTIVITIES

4OA5 Operator Licensing Examinations

a. Inspection Scope

The NRC reviewed the licensees examination security measures while preparing and

administering the examinations in order to ensure compliance with 10 CFR §55.49,

Integrity of examinations and tests.

The NRC performed an audit of license applications before the preparatory site visit in

order to confirm that they accurately reflected the subject applicants qualifications in

accordance with NUREG-1021.

Members of the Joseph M. Farley Nuclear Plant training staff administered the written

examination on July 31, 2020. The NRC administered the operating tests during the

period August 24 - 28, 2020. The NRC examiners evaluated seven Reactor Operator

(RO) and six Senior Reactor Operator (SRO) applicants using the guidelines contained

in NUREG-1021. Evaluations of applicants and reviews of associated documentation

were performed to determine if the applicants, who applied for licenses to operate the

Joseph M. Farley Nuclear Plant, met the requirements specified in 10 CFR Part 55,

Operators Licenses.

The NRC evaluated the performance or fidelity of the simulation facility during the

preparation and conduct of the operating tests.

b. Findings

No findings were identified.

The NRC developed the written examination sample plan outline, the operating test

outlines, and the written examination. All examination material was developed in

accordance with the guidelines contained in Revision 11, of NUREG-1021. Members of

the Joseph M. Farley Nuclear Plant training staff reviewed the proposed examination.

Examination changes agreed upon between the NRC and the licensee were made per

NUREG-1021 and incorporated into the final version of the examination materials.

Seven RO applicants and six SRO applicants passed both the operating test and written

examination. One RO retake applicant, who was granted an excusal from the operating

test, passed the written examination. Two RO applicants, whose applications were

subsequently withdrawn before the operating test was administered, failed the written

examination. Eight RO applicants and six SRO applicants were issued licenses.

Several applicants demonstrated knowledge weaknesses during a job performance

measure (JPM) to recover a dropped control rod in accordance with FNP-1-AOP-19.0,

Malfunction of Rod Control System, Section 1.3, Dropped Rods in Mode 1. The JPM

was designed such that once withdrawal of the dropped rod was initiated, a second

control rod then dropped (i.e., alternate path portion of the JPM); the applicants were

then expected to initiate a reactor trip. Applicant weaknesses during administration of

3

this JPM included failure to reset the rod group step counter, failure to perform a reactor

trip, and failure to interpret plant indications associated with the second dropped rod.

Copies of all individual examination reports were sent to the facility Training Manager for

evaluation of weaknesses and determination of appropriate remedial training.

The licensee submitted one post-examination comment concerning the written

examination and three post-examination comments concerning the operating test. A

copy of the final written examinations and answer keys, with all changes incorporated,

may be accessed not earlier than September 26, 2022, in the ADAMS system (ADAMS

Accession Number(s) ML20276A129 and ML20276A130). A copy of the licensees post-

examination comments may be accessed in the ADAMS system (ADAMS Accession

Number ML20276A128.

4OA6 Meetings, Including Exit

Exit Meeting Summary

On August 28, 2020, the NRC examination team discussed generic issues associated

with the operating test with Mr. Charles Kharrl, Site Vice President, and members of the

Joseph M. Farley Nuclear Plant staff. The examiners asked the licensee if any of the

examination material was proprietary. No proprietary information was identified.

FACILITY AND APPLICANT POST-EXAMINATION COMMENTS AND NRC RESOLUTIONS

A complete text of the facility licensee and applicant post-examination comments can be found

in ADAMS under Accession Number ML20276A128. There were four post-exam comments.

One applicant provided a post-exam comment for SRO Written Exam Item #94; other applicants

provided post-exam comments related to a scenario guide and two job performance measures

(JPMs). The facility licensee agreed with all the applicants contentions.

Post-Examination Comment #1: SRO Question #94

The applicant contended that there were two correct answers for the first part of the question

because NMP-OS-007-001, Conduct of Operations Standards and Expectations, Section

4.28.5, Manual Operation of Motor-Operated Valves (MOVs) and Air-Operated Valves (AOVs),

stated that a motor-operated valve (MOV), which was manually actuated using its handwheel

operator, should be unseated and electrically stroked prior to declaring the valve operable, even

though the same administrative procedure stated that the MOV may be considered operable

when the MOV was manually actuated via the handwheel operator to its required safety

position. The applicant contended that the stem of the question did not specify the availability of

the MOVs electrical power supply, and the word should was a stronger administrative

requirement than may. Therefore, the applicant contended that the stem of the question did

not contain any conditions that would preclude electrically stroking the MOV, which was a

management expectation, even though the procedure allowed that the MOV to be considered

operable as long as the MOV was electrically stroked later.

The facility licensee agreed with the applicants contention and further contended that the past

and current operational practice was to use the motor prior to returning a valve to remote

service unless precluded by plant conditions.

Background

Question #94 was a two-part question:

Enclosure 2

The answer key indicated that Choice A was the correct answer. Neither the facility licensee

nor any of the applicants contested the second portion of the test item. One of the eight SRO

applicants who took the written exam picked Choice A as the original correct answer; four

SRO applicants picked Choice B; one SRO applicant picked Choice C; and two SRO

applicants picked Choice D. During the administration of the written exam, a different

applicant asked the proctor whether power was removed from the MOV when the System

Operator manually operated the MOV.

NRC Resolution: Applicant and facility comment accepted

The first part of the question tested Item g in NMP-OS-007-001, Conduct of Operations

Standards and Expectations, Section 4.28.5, Manual Operation of Motor-Operated Valves

(MOVs) and Air-Operated Valves (AOVs), which stated:

2

The first part of the question asked if the MOV is / is NOT operable. In accordance with

Item g (1), an MOV which was manually actuated using the hand wheel operator

SHOULD [emphasis added] be stroked prior to declaring it operable, which implied a

management expectation that was to be performed unless specific conditions precluded

the action. The stem of the question did not specify the availability of the MOV power

supply or whether an immediate discretionary decision was required; therefore, the stem

of the question did not provide information to imply Item g (2) was necessary, i.e., the

stem did not imply that an immediate discretionary decision by the SRO was required.

Item g (2) stated that an MOV which was manually actuated using the handwheel

operator MAY [emphasis added] be considered operable if the MOV was in its required

safety position, but still required electrical cycling later.

NMP-AP-003, Procedure and Work Instruction Use and Adherence, Section 2.0,

Definitions, stated:

The stem of the question did NOT ask whether NMP-OS-007-001 allowed [emphasis

added] the MOV to be considered [emphasis added] operable, and the stem did not

include any information that implied an immediate discretionary operability decision was

required; therefore, the applicants were forced to make an assumption whether

electrically stroking the valve was possible. Based on an operationally valid assumption,

there were two possible answers.

  • IF an applicant assumed that the power supply was available, THEN the applicant

could select Choice B (not operable) because the management expectation was

to use the motor prior to returning a valve to remote service.

  • IF an applicant assumed that the power supply was NOT available AND further

assumed that an immediate discretionary operability decision was required,

3

  • THEN the applicant could select Choice A (operable) because there was no

known issue with the valve in its required safety position.

NUREG-1021, ES-403, Grading Initial Site-Specific Written Examinations, Section D.1.a

stated, in part:

The following types of errors, if identified and adequately justified by the facility

licensee or an applicant, are most likely to result in post-examination changes

agreeable to the NRC:

  • a question with an unclear stem that confused the applicants or did not

provide all the necessary information.

ES-403, Section D.1.c stated, in part,

If a question is determined to have two correct answers, both answers will be

accepted as correct.

Therefore, the answer key was changed to accept both Choice A and B as correct.

Post-Examination Comment #2: Simulator Scenario 1, Event 5

One applicant contended that Form ES-D-2, Required Operator Actions, for Scenario 1 Event 5

did not align with Revision 23.0 of AOP-100, Section 1.4, Step 3. The applicant contended that

the Form ES-D-2 should be changed to say, IF desired to stabilize the plant and a ramp is in

progress, place turbine on HOLD. The facility licensee concurred with the applicants

contention.

Background

Scenario 1, Event 5 was 1A Steam Generator Feed Pump (SGFP) Controller failure. The

operating test Form ES-D-2 for Scenario 1 included the following Step 3 from 1-AOP-100,

Instrument Malfunction, Section 1.4, SGFP Speed Control:

However, version 23.0 of 1-AOP-100, Section 1.4, included the following Step 3:

4

NRC Resolution: Applicant and facility comment accepted

Version 23.0 of 1-AOP-100 was issued on February 12, 2020; the facility licensee froze the

initial exam procedures on February 28, 2020 following their internal validation of the operating

test. However, the new version 23.0 was not incorporated into the ES-D-2 for the scenario.

Therefore, evaluation of the applicants performance during Scenario 1, Event 5 was completed

in accordance with ES-303, Documenting and Grading Initial Operating Tests, using the

corrected marked-up version of Form ES-D-2 for Scenario 1 Event 5 that reflected Revision

23.0 of AOP-100, Section 1.4, Step 3. In accordance with NUREG-1021, Rev. 11, ES-501,

Section F.1, the marked-up version of Form ES-D-2 will be added to ADAMS.

Post-Examination Comment #3: JPM D, Place Letdown in service after Spurious SI

One applicant contended that the task standard for JPM Step 6 did not align with ESP-1.1, SI

Termination, Step 14.1.4. Specifically, the applicant contended that the phrase Open letdown

orifice isolation valve(s) should be added to the standard. The applicant contended that Step

14.1.4 allowed any one orifice isolation valve to be opened since the word valve(s) meant that

the singular form of only opening any one orifice isolation valve was permitted.

The facility licensee agreed with the applicants contention and further contended that the intent

of Step 14.1.4, according to the ESP-1.1 basis document, was to establish a controlled bleed

path from the RCS to allow lowering and controlling pressurizer level. The facility licensee

contended that ANY one of the letdown orifices provided adequate flow to reestablish a RCS

bleed path, with charging and seal injection in service, to lower and control pressurizer level.

The facility licensee contended that the intent of the AND / OR connectors in Step 14.1.4 was

to preclude two 60 gpm orifices from being placed in service because 120 gpm could exceed

the allowed flow through the CVCS demineralizers. The facility licensee stated that a procedure

change request was subsequently initiated via the corrective action program to enhance Step

14.1.4.

Background

The initial conditions for JPM D were:

JPM Step 6 (Procedure Step 14.1.4) and its performance standard was:

5

ESP-1.1, Step 14.1.4 Action/Expected Response (A/ER) and Response NOT Obtained (RNO)

columns were:

NRC Resolution: Applicant and Facility Comment NOT accepted

In Step 14.1.4, the word valve(s) allowed two options to be performed.

Option 1: Plural valves: Open the 45 gpm (8149A) AND the 60 gpm (8149B) orifice isolation

valves (plural) to achieve 105 gpm.

OR

Option 2: Singular valve: Open ONLY the 60 gpm (8149C) orifice isolation valve (singular) to

achieve 60 gpm.

Step 14.1.4 did not allow ONLY the 45 gpm (8149A) orifice to be opened because of the AND

connection to the 60 gpm (8149B) orifice, and also did not allow both 60 gpm orifice isolation

valves (8149B and 8149C) to be opened.

The basis for establishing letdown, in accordance with FNP-0-ESB-1.1, Specific Background

Document for 1/2 ESP-1.1 SI Termination, was to establish a controlled bleed path from the

RCS, and stated, in part:

6

Normal letdown provided a controlled mechanism for offsetting volume additions

through the charging system. If normal letdown cannot be established, excess

letdown is established to balance seal injection flow. Charging may have to be reduced

after excess letdown is established due to the limited capacity of excess letdown.

The applicant and facility licensee contended that opening any ONE of the letdown orifices met

the intent of Step 14.1.4 because sufficient RCS bleed path flow would be established such that

charging and seal injection flow would be maintained. The JPM initial conditions stated that

pressurizer level was 44% and rising. The letdown flow with only the 8149A (45 gpm) orifice

was ~ 49 gpm; the total seal injection flow was ~ 24 gpm (8 gpm per pump); and the #1 Seal

Leakoff flow was ~ 7.5 gpm (2.5 gpm per pump).

Although the 8149A (45 gpm) orifice could [emphasis added] potentially meet the intent

[emphasis added] of Step 14.1.4 with additional charging flow adjustments, Step 14.1.4 did not

allow only the 8149A (45 gpm) orifice to be placed in service.

NUREG-1021, Appendix C, Job Performance Measure Guidelines, Section B.3 stated, in part,:

Every procedural step that the examinee must perform correctly (i.e., accurately, in the

proper sequence, and at the proper time) to accomplish the task standard shall be

identified as a critical step and shall have an associated performance standard.

Therefore, the task standard for JPM Step 6 was retained because procedure Step 14.1.4 did

not allow only the 8149A (45 gpm) orifice to be placed in service.

Post-Examination Comment #4: SRO Admin JPM, Determine LHRA Access Controls and

Evaluate Administrative Dose Limit Requirements

Two applicants contended that the task standard for JPM Step 2 should be revised to also

permit the use of a flashing light and barrier as a compensatory action to preclude unauthorized

individuals access into the locked high radiation area (LHRA); the applicants contended that the

task standard for JPM Step 2 only allowed an access control guard even though the flashing

light and barrier was permitted.

The facility licensee agreed with the applicants and contended that NMP-HP-302, Restricted

Area Classification, Postings, and Access Control, allowed the use of a flashing red light and

barrier, in lieu of an access control guard, and has been utilized by the facility licensee in the

past, although not on a routine basis.

Background

The administrative JPM involved entering the Letdown Heat Exchanger Room when it was

posted as a LHRA and one element of the JPM was for the applicants to identify the required

compensatory action(s) to ensure only authorized individuals gained access into the LHRA

while a system operator entered the room to manually close a valve. The initial conditions of

the JPM specified that the Letdown Heat Exchanger Room did not have a way to be re-locked

while the system operator was performing the work in the room.

7

JPM Step 2 and its performance standard was:

NMP-HP-302, defined the following boundary requirements for LHRAs:

The standard for JPM Step 2 (access control guard) was based on the 6th bullet, i.e., an Access

Control Guard may be used while an area is being routinely accessed or additional time is

required to establish controlled boundaries. Attachment 4, LHRA Access Guard

Responsibilities Checklist, provided requirements for an individual performing the function of an

Access Guard to a LHRA.

Precaution and Limitation 24 stated:

8

The standard for JPM Step 2 did not include all the options available for compensatory actions

that precluded unauthorized individuals from entering the Letdown Heat Exchanger Room while

the work was being performed, i.e., the standard for JPM Step 2 only identified one option,

which was the access control guard, even though NMP-HP-302 also allowed a flashing light and

barrier with RP Manager approval.

NUREG-1021, Appendix C, Job Performance Measure Guidelines, Section B.3 stated, in part,:

Every procedural step that the examinee must perform correctly (i.e., accurately, in the

proper sequence, and at the proper time) to accomplish the task standard shall be

identified as a critical step and shall have an associated performance standard.

Therefore, the performance standard for JPM Step 2 was revised to include both options, i.e.,

an access control guard or a flashing light and barrier with RP Manager approval. In

accordance with NUREG-1021, Rev. 11, ES-501, Section F.1, the marked-up version of this

SRO administrative JPM will be added to ADAMS.
