Subject:

McGuire Nuclear Station Review of Written Licensing Exams

Dear Sir:

Attached are our specific comments on the RO and SRO written examinations administered here on December 8, 1986. In addition, we also have these general concerns:

1. It appears that the learning objectives stated in our supplied training material were not used in selection of appropriate questions. Several questions appear to have been taken from the body of lesson plans and do not relate to the learning objectives for that lesson. This is inappropriate since our systematic approach to training is based on learning objectives. Lesson plans contain material that is beyond the expected learning objectives, and we strongly feel that questions on exams should be related to learning objectives.

4

^

, 2. It appears that several questions require the verbatim memorization of Tech i Spec action statements that give the operator greater than one hour to take i the appropriate action. We feel that expecting memorization of this type information, which is available for reference in the control room, is ,

inappropriate.

Recommendation Change answer key to read DBW is more negative.

Justification Lesson Plan: OP-MC-RT-RCO, page 34 Lesson Plan reads "Overall effect of core age is that differential boron worth will get continually more negative from BOL to EOL. This is reflected by the DBW curve in the Data Book.

(Data Book Curve 6.2)

Question 1.05 Comment Test answer key reflects wrong answer.

Pago 2 t L Question 1.06 Comment We feel that the explanations given in the answer key are incorrect.

Recommendation For all answers a, b, c, d explanations reference the Data Book Curve 6.5 that indicates the plant conditions that affect shutdown margin which is burnup, Tave, Boron concentration.

Rod height has no affect on shutdown margin.

Justification

1. Data Book curve 6.5

2. Lesson Plan OP-MC-RT-RB, page 14 through 18 Question 1.07 comment We feel that 1/2 of the required answer by the test answer key is not related to question asked. The question only asks "How" and not "Why".

Recommendation Delete the second part of the test answer given for this questicn and allow full credit for the first part which fully answers the question asked.

Justification he feel that, as indicated above, the first part of the test answer given fully answers the question asked.

SECTION 2 Question 2.02c Comment We feel that the required answer by the test answer key is not related to question asked. The question did not ask for the individual NC Pump components. It only asks for additional actions that could occur upon Containment Phase B Isolation signal.

Recommendation We feel you should also accept "the Isolation of the KC System or RN System cooling to the NC pumps" for full credit.

Justification We feel that, as indicated above, the test answer given fully answers the question asked.

Question 2.03b comment Test answer key reflects wrong answer.

We feel that Part C to this question was not specific enough to require the answer indicated by the test key. The answer is only

for pressurizer spray provided by the NC pumps.

Recommendation The actual answers provided by the students may include the pressure difference developed by the NV pumps and ND pumps which ,

is pressurizer Aux. spray supplies.

Justification Lesson Plan: OP-MC-SPS-SY-NC, page 15, 9.e and 9.f i

Question 2.07 j comment j

We feel this question is beyond the scope of required Reactor 1 Operator knowledge.

We recommend this qu4stion be removed.

I i Justification l Lesson Plan: OP-MC-IC-IRE

! No Lesson Plan objectives and Lesson Plan does not provide a clear answer to this question. (Operator is required to know i

the cause of the Urgent Alarm, but is not required to know the i condition that cause the individual failures.)

Recommendation We recommend that an acceptable answer should also be " EMF-46 Trip II alarm is received on high activity in the KC System, it i

will automatically close the KC surge tank vent".

Justification i Lesson Plan: OP-MC-SPS-SY-KC, page 10, 7.b i

f Recommendation Change answer key to read: a. 12

b. 12

c. 33 l

' d. 57 i

The answer should be based on the answer the student indi-i cates in (a). The answer in (a) will dictate the NV System flow i balance values for b, c, and d.

i Justification i 1 The answer key has an incorrect assumption that seal leakoff flow decreases at the same proportion as seal injection flow

decreases. This assumption is wrong because seal leakoff flow 4 is based on the #1 seal gap clearance which is dependent upon the #1 seal pressure difference.

. i Question 2.15 Comment We feel it is beyond the required operator knowledge to memorize relief valve setpoints and the answer key does not reflect all the possible correct answers.

Recommendation Full credit should be received for five relief valves that discharge to the PRT without including the setpoints and the answer key should include the following relief valves:

1. NS pump suction relief

2. NI pump suction relief

3. NI, NV, NS relief valves Contact the McGuire Nuclear Station Training Organization for any answer in question (704)875-2961.

sequencer actuation on a Blackout signal. This should be considered in the students' answers. l 1 Justification The question asks for all the initial automatic actions that I occur for each signal.

Question 3.06 Comment The answer key does not include all possible correct answers.

Recommendation Include as a correct answer for full credit: No, containment spray will not occur because containment pressure is less than the CPCS setpoint of .35 psig."

Justification Lesson Plan: OP-MC-ECC-NS, page 11, 1.5.A.1 Question 3.08a and 3.08d Comment The answer key reflects the wrcng answer.

Recommendation Change the answer key to read:

a. Rods will move out because Tref > Tave and the Temperature Error signal is the dominant signal between power mismatch and temperature error.

d. Rods move in because Tref < Tave and Tref is decreasing due to turbine load decrease. This is the dominant signal and the power mismatch signal t

will also move rods in.

Paga 9 Question 3.13b Comment The student may answer the question between a possible range of 365 psig to 400 psig.

Recommendation Change answer key range to: "365 psig to 400 psig" Justification The test procedures at MNS accepts as a valid test lift pressure a value between 365 psig and 400 psig. The operators may answer the question with these values. There has been a recent incident at MNS in which a PORV operated at approximately 365 psig while in the low pressure. mode of operation. This incident is being incorporated into the Pzr Pressure Control Lesson Plan.

Question 3.16 Comment Answer key does not reflect all possible answers.

Recommendation Add to list of answers: P/A Converter Justification Lesson Plan: OP-MC-IC-IRE, page 23, Sect. 3.e i Question 3.17 Comment l l

The answer key does not reflect correct answer. The NV Lesson Plan reference has an incorrect value for VCT Lo Level auto swap.

Recommendation The correct value should be 1%. We recommend that you accept either 1% or 1.4%. This setpoint error will be corrected in the NV Lesson Plan.

Justification

Comment Answer key is wrong.

Recommendation Change the answer key to read #2.

Justification Lesson Plan: OP-MC-SPS-IC-SPD, page 8 Question 4.02b comment The answer key does not reflect all the possible correct answers. The answer key only reflects case I of the NC Pump Malfunction Procedure.

Recommendation Include the following pump trip conditions in addition to the answers on the answer key for full credit:

Shaft vibration > 20 mils Frame vibration > 5 mils Motor Bearing Temp. > 195'F Stator Winding Temp. > 311*F Any three conditions acceptable for full credit. l l

Justification 1 AP/1/A/5500/08 Malfunction of NC Pump requires the operator to trip the NC pump if any of these conditions exist.

Question 4.03b Comment We feel it is beyond the required knowledge of the operator to memorize specific steps of the subsequent action section of procedures.

Recommendation We recommend that you accept for full credit the following answer: 1. Start two boric acid transfer pumps

2. Open emergency boration control valve (NV-265)

Justification I The operator has all the Abnormal Procedures available for reference in the control Room for specific step sequence.

We feel this question is beyond the acope of required operator j knowledge.

Recommendation Change answer key to read: Increase Justification QPTR by Tech. Spec. definition cannot be < 1; and the answer stated is for the Quadrant QPTR that had the divider barrier failure.
