Dear Mr. Brockman:

In accordance with the provisions of NUREG-1021, "Operator Licensing Examiner Standards,"

Standard ES-201, enclosed are comments by the Browns Ferry Operator Training staff concerning the written examinations administered at Browns Ferry Nuclear Plant, December 12, 1988.

The enclosed comments are offered with the intent of providing assistance to the NRC examiners in establishing the appropriateness of the examination questions.

Also, the comments serve to clarify and expand the answers on the NRC answer key as supported by TVA reference material.

These comments are respectfully submitted, and it is hoped the enclosed comments and proposed resolutions afford the examinees every opportunity to successfully pass the examination based upon'he kndwledge and skills required to safely operate the facility.

Very truly yours, TENNESSEE VALLEY AUTHORITY

GENERAL COMMENT

S The terms, "Power Defect, Reactivity Defect, and Margin of Shutdown," are not used in our training material and 'caused some confusion during the examination.

Please modify future questions to delete the use of these terms and use BFN specific terms.

Point values between the same question on the RO and SRO were not consistent through out.

Examples:

3.01(2.0) 3.09(2.0) 2.04(1.5) 2.06(1.5) 6.01(1.0) 6.05(1.5) required more responses 6.09(1.0) 6.10(1.0) required more responses 3 ~

The length of the examination for the allotted time caused' great deal of problems for the SRO's.

Everyone put down a answer for each question; however, all said that they just wrote something down, without having time to analyze on several questions.

The SRO examination contained 97 questions for a point total of 114.0 and the RO examination contained 62 questions for a point total of 108.75.

This is a total of 35 additional questions for the SRO's to address within the same time period.

In addition, Item 2 above shows that the same required responses received less credit on some questions.

We feel that the SRO examination was far too long and that this affected the ability of the people to demonstrate their knowledge.

Operational Node Switch Sets the mode of operation of the speed and voltage regulators.

<a)

SINGLE UNIT Used when the generator is the only supply to the associated shutdown board.

Speed (frequency) droop

<decrease) from zero load KILOWATTS to full rated load KILOWATTS is less than one percent

<Figure 8A)-

Voltage droop from zero load OUTGOING KILOVARS to full rated load OUTGOING KILOVARS is less than one percent (Figure SB).

Any fast start signal or DC control power loss automatically places the mode of operation to SINGLE UNIT mode, without lighting the indicator above the SINGLE UNIT position.

Regardless of'tart signal type, pulling up the NODE SELECT handle and placing it in the desired position will change the mode of operation and light up the associated indicator above the NODE SELECT switch.

(b)

(c)

UNITS IN PARALLEL Used when two generators are to be-tied altogether.

Speed and voltage droop are identical to SINGLE UNIT mode.

Breaker positions are sensed to determine if the unit is operating in parallel with any of the other 7 diesel generators.

If so, feedback occurs between speed regulators

<and voltage regulators) of the paralleled generators so that stable load sharing operation results.

PARALLEL WITH SYSTEN Used when generator is to be paralled with offsite power.

To ensure stable load sharing with grid speed droop from zero load KILOWATTS to full rated load KILOWATTS is approximately five percent

<Figure SC).

Voltage droop from zero load OUTGOING KILOVARS to full rated load OUTGOING KILOVARS is approximately five percent

1 Discussion:

The suppression chamber-to-dryvell vacuum breakers are located inside the torus and cannot be relied upon to adequately control suppression chamber t

d 11 differential pressure if eater is present on either side of'hese devices.

Spraying the dr~e11 results in condensation of steam an 0

d depressurixation of the dryvell, under which conditions the vacuum breakers will open and permit noncondensibles to return to the dryvell.

Thus before these vacuum breakers become inoperable, the drywell is sprayed so that they can perform their intended function.

The previously identified condition and restrictions regarding initiation and operation of dryvell sprays remain applicable.

Orywell spray is secure shen pressure drops below 2.45 psig to help preclude going negative in pressure.

UESTION 8.20 TVA COMMENT:

Change answer key to accept "A" for full credit.

TVA RESOLUTION/JUSTIFICATION Since the question stated that there was "No estimated repair time,"

the decision to shutdown due to the inop pump cannot be made yet.

In

practice, we WILL get a estimated repair time and make our decision based on that.

This would not violate the "intent" of Tech Spec since we are allowed to operate for 7 days with this equipment out-of-service (Ref; Tech Spec 3.5.A).

Therefore, based on the fact that an estimated repair time is yet to be determined we conclude the answer "A" is correct for. this question.

EPIP-1 classification logic directs the SED to make the protective action recommendations:to state and local authorities when a general emergency is classified and declared.

For purposes of clarifying event classification, the reference to ONP-REP, appendix A has been added to EPIP-1.

- This reference and increased emphasis during classroom and simulator training has been mandated by plant and corporate management.

Following EPIP-1 classification logic, when a general emergency is classified prior to CECC being staffed, attachment'-1 must be completed.

Attachment 1 directs the use of attachment 4 to make the mandated protective action recommendations to state and local civil authorities.

Classroom and simulator training emphasis is placed upon this responsibility and is considered an SED action.

Offsite Emergency Organization a ~

The offsite organization is designated as the Central Emergency Control Center (CECC). staff.

The CECC staff is composed of a CECC Director, a

supporting group of technical assistants, and representatives of other organizations within TVA.

TP-3 b.

The purpose of the CECC and the associated stafF is to provide the facilities and manpower for evaluating, coordinating, and directing the overall activities involved in coping with the radiological emergency.

c.

The CECC (located in Chattanooga) is designated to serve as the central point for information collection, assessment, and transfer during an emergency.

TP-4 C.

Emergency Notification and Activation of the Plan 1.

Emergencies can be caused by natural disasters such as tornadoes or floods, hazards such as aircraft crashes, releases of toxic gases, or breaches of plant

security, as well as by conditions involving plant systems directly.

2.

Recognition of the emergency class is primarily a judgement matter.

The initiating conditions used for recognizing and declaring the emergency class are based on specific measurable values or observable conditions defined as Emergency Action Levels (EALs).

3.

Upon detection of an emergency, the Shift Onerations Supervisor

{SOS) will determine the proper event classification using Emergency Plan Implementing Procedure (EPIP)-l.

(This responsibility may not be delegated.)

He then acts as the Site Emergency Director and If more informat i or is needed, the SOS should refer to Appendix A of ONP-REP.

Site Area Emergency This classification assures that response centers are staffed, monitoring teams are dispatched, personnel required for evacuation of near-site areas are at duty stations if the situation becomes more

serious, and provides current information for, and consultation with, offsite authorities and the public.

EPIP-4 contains the directions for activating the emerg'ency response for the Site Area Emergency.

2.

Upon declaration of this class, the actions described in E.2. are performed.

In addition:

a.

A precautionary evacuation of nonessential personnel is initiated in

.accordance with EPIP-8.

3.

b.

Any appropriate protective actions for the public are rec'oIINIended to State agencies by the CECC.

The initiating conditions and emergency action levels which require the Site Area Emergency are explained in Appendix A of the Radiological Emergency Plan, section A.l".3.

EPIP-4 directs that the event be reevaluated at least every two hours.

TP-6 G.

General Emergency This classification initiates predetermined protective action for the public, provides continuous assessment of information, and initiates additional measures as required by releases of radioactivity.

EPIP-5 contains the directions for activating the emergency response for the General Emergency and the guidance for ma~ing protective action recommendations.

The Site Emergency Oirector must make any required recommendations until the CECC is staffed.

(This responsibility cannot be delegated.)

>"!y 20 1S87 2.

When a system, subsystem,

train, component, or device is

determined to be inoperable solely because its onsite power source is inoperable, or solely because its offsite povec source is inoperable, it may be considered operable for the purpose of satisfying the requirements of its applicable Limiting Condition For Operation, provided:

(1) its corresponding ofisite or diesel pover source is operable; and {2) all of its redundant system(s),

subsystem(s),

train{s), component(s),

and device(s) are operable, or likewise satisfy these requirements.

Unless both conditions (1) and (2) are satisfied, the unit shall be placed in at least Hot Standby vithin 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in at least Cold Shutdown within the folloving 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

This definition is not applicable in Cold Shutdown or Refueling.

This provision describes what additional conditions must be satisfied to permit operation to continue consistent vith the specifications for power sources, vhen an offsite or onsite power source is not operable.

It specifically prohibits operation when one division is inoperable because its offsite or diesel power source is inoperable and a system, subsystem,

train, component, or device in another division is inoperable for another reason.

This provision. permits the requirements associated vith individual systems, subsystems,

trains, components, or devices to be consistent vith the requirements of the associated electrical pover source.

It allows operation to be governed by the time limit of the requirements associated vith the Limiting Condition For Operation ior the offsite or diesel power source, aot the individual requirements for each

system, subsystem,

ENCLOSURE 4 NRC RESOLUTION OF FACILITY COMMENTS Generic Comments 1.

Comment noted.

During the pre-examination review, it was noted that the term "Margin to Shutdown" was not used at Browns Ferry.

When asked for substitute terminology, the facility reviewers suggested the term "Margin of Shutdown".

No mention of concern for the terms "Power Defect" or "Reactivity Defect" was made.

It is not felt this was detrimental to the examination since all candidates were specifi-cally instructed to question any terms that were confusing or not plant specific.

No candidate questioned the use of these terms during the examination.

2.

Comment noted.

3; Comment noted with exception.

The typical Region II BWR exam contains between 105. and 115 points.

The Browns Ferry exams fell within this range.

The reason for the difference in the number of questions between the RO and SRO examinations is that the RO examination contained more multi-part questions than did the SRO examination.

When the number of required'esponses is compared, the length of the two examinations is almost the same -

153 responses required of the 'RO exam'inati'on versus 152'esPonses required of the SRO examination.

Additionally, the proctors monitored the progress of the SROs and noted that several spent an excessive amount of time on Sections 6 and 7.

As a result, these candidates had only a short period of time to complete Section 8 let alone time to perform any problem analysis.

Since the other SRO and RO candidates had no trouble with the exam, it is suggested that the Training Department's exam taking techniques be reviewed.

4.

Comment noted.

The intent of the pre-examination review is to ensure the technical accuracy and operational relevancy of the written and simulator examinations.

Additional benefits of this process are a

reduced number of interruptions during the examination for clarifica-tion of questions and a reduced number of post-examination facility comments.

The facility should ensure that the highest quality personnel are provided to guarantee the future success of this review process.

SRO Examination guestion 6.10/2.06 NRC resolution:

Comment noted.

The supporting reference material provided by the facility does not address seal damage.

Instead, it addresses increased drive maintenance.

Therefore, the answer key has been expanded to accept answers indicating increased CROM maintenance.

guestion 7.22 NRC resolution:

Comment accepted.

The answer key has been changed as recommended by the facility.-

guestion 8.05 NRC resolution:

Comment accepted.

The'nswer key has been changed as recommended by the facility.

guestion 8.20 NRC resolution:

Comment accepted.

The answer key has been changed as recommended by the facility.

guestion 8.22 NRC resolution:

Comment partially accepted.

The additional reference material supplied by the facility clearly states that classification of the event and recommendation of protective action cannot be delegated.

These answers will be accepted as alternative correct responses.

The additional reference material,

however, does not support the response of "determining radiation dose limits" as an acceptable response.

guestion 8.24 NRC resolution:

Comment partially accepted.

-The facility justification states that TS 1.C.2 applies.

Therefore, simply deleting the incorrect response as recommended by the facility is inappropriate.

The answer key has been changed to require TS 1.C.2 as a full credit answer.

RO Examination guestion 2.11 NRC resolution:

Comment accepted.

The answer key has been expanded to accept "D/G continues to run" as an alternative response.

It should be noted that following the pre-review of the examination the answer key was

changed, as recommended by the facility, to substitute "shifts to the single unit mode" for "continues to run unloaded".

guestion 3.12b NRC resolution:

Comment accepted.

Based on a review of the answers given by the candidates, the clarity of this question may not have been sufficient to elicit the desired responses.

Therefore, the answer key has been modified to accept the three individual fast start signals as independent answers.
