Exit Meeting l

An exit meeting was conducted on September 3, 15'87, with the following persons in attendance:

l 1

Northern States Power L. Eliason, General Manager, Nuclear Plants W. Shamla, Plant Manager, Monticello D. Antony, General Superintendent, Operations G. Earney, Training Superintendent M. Brandt, Operations

'R. McGillic, Operations Traisiing Supervisor USNRC J. M. Keeton, Chief Examiner J. Bjorgen, Examiner M. Daniels, Examiner The following items were discussed during the exit meeting:

a.

A potential weakness exists in the Abnormal Procedures. The immediate actions in the majority of the procedures are, " Verify Automatic Actions and Notify Shift Supervision." However, subsequent actions include actions that must be performed in a very short time span and would appropriately be considered as immediate actions. A specific example is " Loss of RBCCW," which requires tripping the recirculation pumps and scramming the reactor within 60 seconds as subsequent actions. A recommendation was made to facility management that these procedures be reviewed and revised to clarify those operator actions that should realistically be considered inmediate actions.

b.

In the previous Exam Report, No. 50-263/0L-87-01, dated April 23, 1987, the E0Ps were identified as being a potential problem area.

The primary concern was that the E0Ps are not " user-friendly."

Although the same concern exists because no changes have been made, facility management stated that they have contracted an outside organization to upgrade the E0Ps.

~DocketLNo. 50-263 Comment:

1.02 Answer The answer for Part 2 actua11y'contains three reasons for the power decrease:

1.'

-Recirculation pump 'down shift (run back) adding negative reactivity due to void coefficient.

2.

Reduced feedwater flow adding negative reactivity due to void coefficient.

3.

Decreasing reactor water level adding negative reactivity due to void coefficient.

Any one of these answers should be sufficient for the second reason.

Resolutions Comment partially accepted. Answer key changed to accept the following:

1.

(The decreased feed flow results in) decreased subcooling which adds negative reactivity due to.the moderator coefficient.

2.

The recirculation pump down shift adds negative reactivity due to the void coefficient.

3.

(The reduced feedwater flow results in) decreased subcooling which adds negative reactivity due to the void coefficient.

4.

(Provided the candidate states the assumption that the l

recirculation pumps trip on low reactor water level) decreasing' reactor. level adds negative reactivity due to the void coefficient.

.etc.

10 CFR 55 Part:43 states that the~ written examination

'Vi' M

for a Senior Operator will ~ include the same items, plus

" Facility ' Operating Limitations in the Technical Specification and their' Bases."-

This has.been interpreted in the past that a R0 candidate does-not have te be as cognizant of the bases as a SR0 candidate;.

therefore, we do not emphasize bases as strongly to the R0 candidates and we doLnot test on bases questions. We feel -

Answer key changed to include the additional correct responses.

Point value for the question remains at six responses at 0.4 points each.

Comment:

2.10 Answer The question does not elicit the answer given, in that it asks why both heater hand switches are never placed in the on position while operating SBGT in manual, it does not ask for what resulting damage will occur. The answer supplied in the answer key was taken from the SBGT lesson plan and used in class as amplifying information. We teach the candidates to answer question whenever possible per the Monticello Operations Mar.ual.

The General Precautions section of B.4.2 (SBGT) contains information on not placing heater switches in "on" while running in manual.

The candidates have been informed as part of their

l l-6 l

watch standing' 0JT that these heaters will not trip on high temperature while in manual and therefore should not be-used, this should also be a correct answer.

Reference:

B.4.2-0035, 0036 Resolution:

Comment accepted. Answer key changed to accept the following alternat. answer:

The heater should not be used while in manual operation because the heaters will not trip on high temperature.

Comment:'

3.01 Question and Answer a.

Que> tion is "open-ended" in that it does not specify the number of responses required for full credit nor does it separate tne point totals between Parts a and b which the candidate could use for guidance.

NUREG-1021, Revision 4 ES-202, Page 5 states that "open-ended" questions should be avoided.

If a specific number of responses are required, the question should clearly state that expectation so the candidate will know when the answer is complete.

Full credit should be given for the four components / systems listed in the Operations Manual.

Comment:

3.02 Answer b.

The change in core flow from a switch from the EPR to the MPR (approximately 918 psig to 923 psig) would be so small it would not be noticed by an operator using available indication. An acceptable answer could also be "no change" due to the slight pressure change.

Resolution:

Comment partially accepted. Answer key for Part b changed to the following:

Comment:

4.09 Answer b.

Answer could be false if the operator felt he should tell. his immediate-supervisor (Shift Supervisor) and let the SS inform the General Superintendent Operations, or if-he was not medically qualified due to taking medication.

Reference:

4ACD-4.7 Page 17 Paragraph F

- Resolution:

Comment not. accepted. Monticello Administrative Control Document 4 ACD-4.7 states the following:

'4'ACD-4.7, Page 5, Paragraph 5.6.1 states "Ros and SR0s-shall be responsible for informing the General Superintendent

' Operations-(GS0) upon. determining they do' not meet the medical

. qualification delineated in 10 CFR 55."

Attachment:

1 4 ACD-4.7,.Page 17, Paragraph g states "R0s and SR0s.shall immediately inform the General Superintendent Operations (GS0) upon determining they do not meet the medical qualifications delineated in 10 CFR 55."

4 ACD-4.7, Page 17, Paragraph f states " Operators shall immediately inform the Shift Supervisor if taking medication that may impair their ability to operate the plant. The Shift Supervisor shall determine if a relief is warranted."

The Monticello Administrative Controls clearly state the requirement that the operator is responsible for notifying the GS0 if not meeting the medical qualifications.

The Shift Supervisor is only responsible to determine if a' relief is required for the operator.

Comment:

4.10 and 4.12 1

-The Abnormal Procedures C.4 contain immediate operator actions l-which state, " verify automatic actions;" there is also a section which states, "The possible automatic actions which may occur."

l 4 ACD-4.2 (Integrated Operating Procedures) concerning automatic actions states "The Automatic Actions that will probably occur as a result of the event should be identified."

l i

10 4 AWI-4.2.1 draft copy'(Abnormal Operating Procedures (C.4)

Writer's Guide) concerning automatic actions states, "The Automatic Actions section shall list the pertinent najor system automatic actions that the operator could exp1ct to see following the casualty."

The intent of the imm:diate operation action to " verify automatic actions" is for the operator to identify the event which is occurring and verify that auto _matic actions which should have v. curred did in fact occur.

It is not expected that all automatic actions listed will occur every time an event occurs, the automatic actions that occur depend on the initiating cause of the event.

The intent of the automatic action list in the procedure is not to list all the expected actions which would or could occur. The intent is to ensure the operator verifies automatic actions which will occur for that particular situation and if 1

the proper initiating signals are present.

(i.e., Group 1-5 i

isolition, diesel generator start, ECCS Initiation, etc.)

Depending on the event there are automatic actions which can and do occur which are not listed in the Abnormal Procedures.

A good example is the Reactor Scram procedure C.4-a; not listed in the Procedure Automatic Action List are items'which normally occur af ter a high power scran, such as SBGT start, secondary containment isolation, group 2 isolation, group 3 isolation, etc.

If the scram were to occur from low-low water level events such as Group 1 isolation, Recirculation pump trip, HPCI start, etc.

.j would occur.

The lists of Automatic Actions in the Abnormal Procedures are not all inclusive, other automatic actions should and will occur.

Reasonable answers, other than those listed in the scram procedure should be counted as correct.

[

Paragraph 6.2.3.5, "Immediate Operato, Actions" states, "Immediate operator actions are those actions that operators should take immediately, when there are indications of an off normal situation. When applicable, the actions shall be generic steps common to all abnormal procedures. With the exception of C.4-A, Reactor Scram, they should include the following:

1.

Verify automatic actions or manually initiate if they have not occurred.

T-t,

-11

-2.

Monitor the blant for entry conditions to the Emergency Operating Procedures, Operations Manual Section C.S.:

3.:

Notify shift supervisor of the' plant condition.. These actions are normally performed without having to refer to-a' procedure.

' 4 ACD-4.2, Page 4, Paragraph _6.2.6 states, "During. abnormal conditions, applicable Abnormal Procedures in Section C.4 of the Operations Manual should be referred to after the immediate actions have,been taken and the situation is under control."

TheLexamination questions stated to list-the automatic' actions in'accordance with the procedures. The'Monticello administrative documents state that the operator should refer to the procedure after the immediate actions have been completed._ If the operators do not know the automatic actions for the procedure

~

then the operator. will. not know what immediate actions are required.

Question.7.05

. Operations Manual C.2 Page 32 states "take action as required by technical Specification 3.1.B.," Technical Specification

' 3.1.B. states " satisfy the minimum requirements by placing appropriate devices, channel, or trip system'in the tripped condition, or place and maintain the plant under the specified required condition using normal operating procedures."

The candidate may answer take action required by Technical Specifications, place RPS channel in trip condition or commence reactor shutdown until APRM's are readjusted.

Comment:

Question 7.08 The answer key lists a reference of C.5-1101 and C.5-1101.

There are no immediate actions in the E0Ps. The question would lead the candidate to answer referring to the abnormal 1'

~

12 procedure. The automatic ' actions listed in the abnormal procedure are only some of the auto functions that may occur during that particular event, given that the scram occurred due to high drywell pressure, Group I isolation, and RCIC initiation, should not be verified because their logic does not receive a drywell pressure input.

Some of the events to verify for high pressure are:

Group 2, 3 isolation Diesel generator starts ECCS actuation ie., HPCI, CS, LPCI Reactor Scram Resolution:

Comment noted. The comment was taken into consideration during grading. Tha answer key is unchanged.

Comment:

Question 7.11 The abnormal procedure assumes the reactor is at power. The question could be answered to trip the CRD pump if the candidate assumes the reactor is shutdown or in refuel mode when loss of RBCCW occurs.

I QUESTION 8.11 (2.00)

)

i TRUE or FALSE?

a M

a.

The Technical Specifications require reactor shutdownfif more than 6 "non-fully inserted rods are inoperable," because the reactor cannot meet the required shutdown margin if another withdrawn rod sti cks.

b.

The surveillance requirement for control rods allows one rod in a two-by-two array to be cycled one-notch only once per month instead of weekly.

c.

The Technical Specifications allow the Rod Worth Minimi:er to be bypassed during startup at beginning of rod withdrawal provided a second operator or engineer verifies each withdrawal.

d.

A control rod with an inoperable accumulator is fullv inserted and electrically disarmed; therefore, the accumulator is not considered inoperable.

QUESTION 8.12 (3.00)

You are Shift Supervisor during power operation.

One recirculation pump

-has tripped due to electrical problems and cannot be restored for several days.

The load dispatcher wants you to stay online because of high power demand.

Answer the f ollowing questions with regard to Technical Specification requirements.

Of'erdidy a.

WHAT TWO

'rty limits must be changed and HOW MUCH must they be changed?

b.

The APRM Scram and Rod Blocks must also be reset; given S < 0.58 (W-dw) + 6 2*/., IDENTIFY the term that must be changed and STATE the new value.

QUESTION 8.13

(.50) 7 RUE or FALSE?

In accordance with 4 ACD-3.5, " Plant Operations Key Control," the key,s requi red to shut down the reactor subsequent to abandoning the control room must be logged out of the Shift Supervisor?s key cabinet.

ANSWER 5.05 (1.50)

Power Coefficient of Reactivity is the change in reactivity f or a 1%

change in reactor power.

(0.5) a.

During reactor startup, the moderator temperature coefficient is dominant.

(0.5) b.

At power, the void coefficient is dominant.

(0.5)

REFERENCE Monticello Reactor Theory, Chapter 4 292OO4K114

...(KA'S)

ANSWER 5.06 (2.50)

Longer (0.5)

Because the power down transient is limited by the decay of the long-lived delayed neutron precursors (0.5) whereas, the power up transient is dependent on prompt neutrons (0.25) and short-lived delay neutron precursors.

(0.25)

The down transient is stabilized by the void coefficient (alpha V)

(0.25) and the decrease in doppler (alpha D)

(0.25).

The up transient is stabilized by the void coefficient (alpha V)

(0.25) and the increase in doppler (alpha D)

(0.25).

(Accept any reasonable, correct discussion of the effect that doppler and void coefficient have on stabilizing power.)

! ANSWER 3.02 (2.25) a.

Increase [0.253 due to the control valves throttling shut in response to the pressure regulator system shifting from the EPR to the MPR and the MPR setpoint being at higher than the EPR EO.53.

b.

Increase EO.253 the increased pressure reduces the void content of the two phase mixture in the core. Less two phase flow, less restriction to core flow EO.53 -or-no indicated flow change

~EO 253 due to the small change in pressure no change in core flow would be indicated-

[0.53.

c.

Increase [0.253 higher reactor pressure collapses voids and a negative void coefficient adds positive reactivity and increases power EO.53.
