Subject:

McGuire Nuclear Station Review of Written License Examinations

Dear Sir:

Attached are our specific comments on the Reactor Operator and Senior Reactor Operator written examinations administered April 18, 1988 at McGuire Nuclear Station.

In addition, as a general comment, several questions depended too heavily on rote memorization of reference material e.g. question 4.02 which referred to a table in a tech spec interpretation; question 4.09 which referred to fuel maneuvering limit tables in the data book; and question 4.15 which referred to reactor site boundary criteria in 10CFR100.

Very truly yours, j l

-e t REACTOR OPERATOR EXAM COMMENTS Page 1 QUESTION 1.06 Concern:

The question requires the RO to determine the net result between two off setting effects; faster dilution of NCS at high boron concentration versus higher differential boron worth at lower boron concentrations; without the use of differential boron worth curve or dilution rate tables which include 1200 ppm. -

Recommendation:

Accept answer C and B as correct. Or at least partial credit for C since it demonstrates knowledge on the part of the operator.

Reference / Reason:

During operation in the control room, the operators have these curves available to them for reference and are not required to memorize them. Selecting item C or B indicates sufficient knowledge of effects.

Concern:

This question involves two effects on axial flux distribution:

1) Rod position - inserting Rods drives AFD more negative
2) Power level - Reducing power shifts AFD toward the  ;

positive l Answer C could also be correct since AFD being more negative )

than the target value of -3.0 implies that the axial power distribution has shifted more negative than the full power axial distribution. j J

Recommendation:

Allow credit for C or D. Or at least partial credit if item C s selected since it demonstrates knowledge on the part of the operator.

concern:

Opera (Jrs.may not put all three Pump Head Curves on same Graph. The point break down in the answer key gives .2 for "correct placement". If the correct placement means the telationship between the ND, NT, and NV Pump Curves on the smne Graph, some operators may be penalized unnecessarily.

The question doesn't clearly emphasize that all three Pump Head Curves should go on the same Graph so the relationship betwat" them can be shown.

Recommendation:

, ~rators should not be penalized if they put the Head Curves on separate Grap.9 such that the relationships are not shown.

Reference /Rssson:

When reviewing question it was not apparent that all three curves needed to gc on one Graph until we looked at the answer key.

QUESTION 2.03 Page 9 Concern:

At McGuire, The Plasma Display for RVLIS for the given condition would have invalid indicated with no values shown.

Therefore the operator would not see 70% and 106% as described in the question.

Recommendation:

The question has too many technically incorrect conditions / assumptions to be salvaged. Throw out question If question is not thrown out accept C as an alternate answer since it is partially correct just as answer A is partially correct i.e. for Pump's running with UR RVLIS failed it would indicate pegged high which would be 120% not 106%, also for Pump's running UR RVLIS normal indication is pegged low at 70% not 106%.

Reference / Reason:

The Lesson Plan Referenced in the answer key reflects the indications which would be seen on RVLIS vhen the read out was meter indication. The McGuire Plant no longer has meter indication. The indication now is computerized plasma display. These displays will only indicate P when the instrument is valid i.e. Pumps on or off.

QUESTION 2.11C Page 12 Concern:

Valve nomenclature in question is incorrect. ND-43 should be NS 43. Valve ND-38 should be NS 38. The name "ND Aux Spray Valves is Correct." Some Operators may have caught this and assumed it was a "Trick" question. Inaddiclon, ND to Aux Spray would only be available if ND was on the containment Sump since NS 38 and NS 43 require the Sump Valve to be open before they can be opened.

Recommendation:

Inadditon to accepting true; false should be accepted if it is stated that valves are NS 43 and 38 and not ND 43 and 38 or if it is stated that the statement is not always true since ND to Aux Spray is not.always available since it must be aligned to the containment Sump in order to open NS 43 and 38.

1 Since the question only required a true or false, many operators may not qualify their answer. If a large number of operators miss this question, it should be re-evaluated as to whether it should be thrown out.

QUESTION 2.16a Page 13 Concern:

i To answer four(4) modes of operation of this system the operator must include "train A".and "train B". The two basic modes of operation of this system are "Series" and "Parallel" and train related modes of operation.are normally not referred to as such.

Recommendation:

Change question point values to place more weight on the "Series" and "Paralled" alignments and less importance on the train relationship. Request a change to reflect "Sericsd (0.4) "Parallel" (0.4) and the remaining (.2) pts applied to the train relationship.

QUESTION 2.20 Page 16 Concern:

Question asks why "A" RN Pump instead of "B" RN Pump supplies containment ventilation units. It does not ask why RN supplies these units during a blackout situation. The answer key requires that_the operator state that the RV Pumps have lost power (.S pts).

Recommendation:

No requirement in answer key for student to state that the RV Pumps have no power. Full credit given for "greater NPSH" or "Cooler Water Supply".

Reference / Reason:

Answer key requires more than question asks.

l Concern:

Part a) Operators have no ETQS task related with the operation of the Incore Instrument Panel.

Operation of this panel is normally conducted by  :

plant performance personnel. Due to this the l answer key seems to require too much detail in the answer required for full credit. Also, the point j value is higher than is reasonable for the '

question.

Part b) Answer states "Honeywell Indicator". Honeywell is the vendor name and should not be part of required answer. Also, answer does not reflect the possible answers: Inadequate Core Cooling Monitor (ICCM) display or SSF which also have temperature displays of the Incore Temperatures, and are separate from the OAC.

Recommendation:

Part a) Allow less detail in answer for full credit example:

1) Calibrate - allows calibration of detectors
2) Emergency - back-up path
3) Common Group - back-up to calibration path
4) Storage - stores detectors Reduce overall point value of question Part b) Allow full credit for either c( the following answers:
1) Temp. Indicator on panel i
2) ICCM display Reference / Reason: l

i 1

Concern: i i

The question is not clear about whether it wants the l immediate eftects of the S/G level channels failing or if a  !

Reactor Trip would occur some time later as a result of the I failure. l I

our S/G level control circuits controls off of S/G level channel 1 normally. If this channel fails .aw the control I circuit will try to increase that S/G level back to program level. However with the channel failed level will continue  :

to increase until P14 (82% LVL) is reached. P14 will cause l the Turbine to Trip which in turn will cause the Reactor to l Trip. I l

1 Recommendation: l In additio.1 to the answer key, if the operator says yes the l Reactor Will trip because the failed channel 1 would cause A I S/G to feed up to P14 which will trip the Turbine which trips the Reactor, this should also be acceptable.

QUESTION 4.02 Page 27 Concern:

This question requires noma ization of a table out of a Technical Specification 1cttrpretation. Since this document is readily available in the control room for review this is beyond the required knowledge of a Reactor Operator. We feel the operator should be aware that there is an interpretation associated with operating above 100% RTP and refer to this interpretation when necessary.

Recommendation:

Since the RO would have to be aware of a time limit associated with operating above 100% RTP, then we recommend i that both "C" or "D" be accepted for full credit since both answers show interpretation knowledge. Since the limit is 60 min. operating of 30 minutes would also be allowable.

Reference / Reason:

Tech. Spec. interpretations are readily available as  ;

reference material in the control room. Student Awareness that there are item limits for operating at 100.5% powec is sufficient to ensure that this interpretations would be referred to under conditions specified in the question.

QUESTION 4.09 Page 30 .

f Concern:

Question does not provide sufficient information for the operator to determine if the fuel is conditioned or not.

The question stated that the Reactor had operated at 70% for one week, but it did not say if this was following a refueling shutdown or if the Reactor had operated above 70%

FP prior to the past week of 70% FP operation.

Inaddition, the operating procedures directs the operator to refer to the Data Book for fuel manuevering limits prior to increasing power (OP/1/A/6100/01 page 18 note following step 3.2.75 and OP/1/A/6100 page 1 note following step 2.4).

The operator is not required to memorize this information and it is readily available in the control room.

Recommendation:

Throw out question if question,will not be thrown out accept either of the following as correct.

1) Unconditioned fuel - 3%/HR all the way to 100% FP
2) Conditioned fuel - 10%/HR to 90% then 3%/HR to 100%

Reference / Reason:

We have no training objectives which requires an RO to memorize the fuel manuevering limits. The fuel manuevering  !

limits are readily available in the control room and the l procedures directs the operator to use them when required.  ;
