EXAMINATION REPORT a.

EXAMINATION REVIEW COMMENT RESOLUTION In general, editorial comments or changes made durir.g the examination, review, or subsequent grading reviews are.not addressed by this resolution section. 'This section reflects resolution of substantive comments made by CPSES. The only coments addressed in this section

- are those which were not accepted for incorporation.into the examination and/or answer key.

Those coments accepted are incorporated into the master examination key which is included in this report.

Comments from CPSES may be paraphrased for brevity. The full text of the comments is attached.

5.06 The question is similar to 5.04 a.nd should be dropped from the examination. The question is also double jeopardy between Parts a. and b.

Adjust answer in Part b to allow

- answer given in Part a.

The question is totally confusing in that the question refers to the ratio of PU-239 and PU-240 atoms to U-235 atoms in relation to delayed neutron fraction and reactor period, however this ratio has little or nothing to do with the doppler coefficient.

The ratio of PU-239 and PU-240 to U-238 does. Therefore Part c. should be dropped from the exam and points adjusted.

If question is allowed, no point value is assigned for the how. Reassign point values for all 5.06 for equal weighting for a, b, and c.

2 Resp; Partially accepted.

The only change made to the key was to allow answer in Part b. to reflect assumption made.in Part a.

The candidate's performance was 95 percent regardless of the change.

Point value for Part c. was not allowed as this same information was solicited-in Question 5.04.

The comment about similarity to Question 5.04 is not understood as the only comon thread is doppler coefficient, which candidates I

are asked to evaluate from two different perspectives.-

5.13 The wording "action" may have confused some examinees and led them to think of indications. Maximum grader discretion.

Also accept c. for full credit because the action of raising RCS temperature means there is a greater delta T between the heat source and the heat sink and the thermal driving head is proportional to the delta T.

-Resp:

Coment not accepted.

Deliberate operator action to enhance natural circulation should be to carefully decrease heat sink temperature vice increase RCS temperature.

6.11.c.1 Change answer to'yes because answer concerns the basic flow path of the Containment Air Cooling and Recirculation System (CACRS) during a LOCA condition.

Since the CACRS is tripped upon receipt of an "S" signal, this does represent a significant change in the basic flow path as air will no longer be drawn into, cooled by, and discharged into the CACRS plenum.

Resp:

Not accepted.

Flow path does not change in the interim between trip and restoration. Only the. flow. conditions change.

7.04.a The PDP and PCV-131 are the major components manipulated to form a bubble in the pressurizer.

Change answer to accept PDP.

Resp:

Not acceptsd.

The question solicits valves that are manipulated. The answer was expanded to include only 2 out of 3 possible valves.

7.06 Answer d. is incorrect. Steam generator becomes "faulted" implies a major cooldown of the RCS, and depressurization of the steam lines. Both will actuate SI which is equivalent to emergency boration.

3 Resp:

Not accepted.

SI is not the equivalent of operator-initiated emergency boration.

8.03.a Answer should include Boration Systems Flowpath, TS 3.1.2.1-and 3.1.2.2.

Resp:

Not accepted.

This Technical Specification is not applicable to the stated scenario.

8.03.b The answer for this question should read required by Technical Specifications, or necessary for inventory control.

Resp:

Not accepted.

Inventory control is'always a basis and is acceptable for no credit.

However the basis in the Technical Specifications does not say "required by Tech.

Spec's," and will not be allowed.

b.

The following apparent problems or areas of weakness were observed by by the examiners:

l (1) Several candidates were unfamiliar with, and could not find out the crux of the most recent revision (5) to the facility Technical Specifications.

How'AND why will Axial Flux Difference change if reactor power is reduced from 100% to 50%7 Assume the reactor is operating at 100% power with all rods out'(ARO), early in cycle life at equilibrium Xenon conditions when power is reduced to 50% by borating (no rod motion).

Neglect changes due to Xenon.

(1.5)

ANSWER 5.01 (1.50)

Due to the greater decrease in the temperature of the coolant exiting the core' relative to the decrease of the inlet coolant ( 0. 5 ),

more positive reactivity will be added in the upper core regions (0.5), resulting in a more pos it ive (less negative) AFD [0.51 (1.5)

QUESTION 5.08 (2.50)

Answer TRUE or FALSE to each of the following statements concerning Xenon.

a.

At full power, with equilibrium conditions, approximately one half of the xenon is produced by iodine decay and the other half is produced directly from fission.

b.

When a reactor is shutdown, xenon burnup effectively stops while the decay.of iodine continues.

Therefore, the xenon concentration starts to increase.

c.

The production of xenon from iodine decay continues for up to approximately 35 hours4.050926e-4 days <br />0.00972 hours <br />5.787037e-5 weeks <br />1.33175e-5 months <br /> after a reactor shutdown.

Because all production of xenon has ceased at this time, xenon concentration reaches its minimum level in the reactor core, d.

Xenon production and removal increase linearly as power level increases; i.e.,

the value of 100 percent equilibrium xenon is twice the value of 50 percent equilibrium xenon.
