SUMMARY

NRC administered written and operating examinations to three Reactor Operator applicants =and one Senior Reactor 0perator (Instant) applicant. One Reactor Operator applicant passed the examinations. One Reactor Operator applicant failed the written examination, one. Reactor Operator failed the operating test, and.the Senior Reactor Operator applicant-failed the written examination. b 5 9212040340 921123 PDR ADOCK 05000116

REPORT DETAILS

1. Examiners:.

Warren Eresian, NRC Richard Miller,' Sonalysts

2. Results:

R0 SRO Total IPass/ Fail) (Pass / Fail) IE1111 Fail) NRC Grading: 1/2 0/1 1/3

3. Written Examination:

Two Reactor Operator applicants passed the written examination, and one Reactor Operator and one Senior Reactor Operator failed the written examination.

4. Opt .61ng Tests:

Two Reactor Operator applicants and one SR0 applicant passed the operating test, and one Reactor Operator failed the operating test.

5. Exit Meeting:

The following personnel attended an exit meeting on November 3,1992 to discuss the examination: Warren Eresian, OLB Examiner, NRC John Adams, Reactor Manager, Icwa State Reactor Facility

  .          Mr. Eresian and Mr. Adams discussed the written examinatica, and Mr.

Adams provided facility commenta. n i

. The following are comments concerning the N.R.C. RO/SRO license exam administered on 11/02/92. The exam was reviewed by Richard Danofsky, Facility Director, and John Adams, Reactor Manager. Comments:

1. Problem A-005 None of the answers provided in question A-005 were correct. We feel the correct answer for this $1.11. This answer can be supported with the following calculations:

SDM = (1 Keft) / Keff Keffian ==> = 1/ (1-p an mm) p an == = (1.1 $) * (0.00763 Ak / k / $)

                         = -0.00839 Kef11en ==> = 1/ [1 - (-0.008393)]
                             = 0.99168 SDMAt = (1 - 0.99168) / 0.99168
                       = 0.00839 Ak/k SDMs = 0.00839 / 0.00763
                     = 1.10 $
2) Problem A-011 We feel the question was improperly written for the indicated answer. We think that the question should be written as follows for the given answer (D):
     "Which ONE of the following is the expected momentajy response of the reactor when the -

source is withdrawn to its storage position? " Without the word "mementary" the correct answer should be "(B) The reactor period will become slightly longer and then stabilize." This assumes the reactor is critical at the time when the source is removed from the core. I wouie also like to point out that the section of the Rx Operation-Normal procedure referenced for this problem does contain the word " momentarsj". 3 Problem A-012 - We feel that the answer is correct, but Lamarsh, Introduction to Nuclear Engineering ,1975, is not used to train reactor operators at this facility. The affects of

control rods on the factors of the six factor formula was never coverd during the candidates training.

4. Problem A-015 We have no disagreement with the answer to this question, but the relative absorption cross-sections of the different poisons was never specifically covered in training. Boron is the only poison we specifically talk about in our training due to its use in our control rods. Xenon and Samarium are only mentioned briefly since our operation time is very restricted at higher powers (less than or equal to 10 kw-hr in any 7 day period) due to argon-41 production. Our normal operation is at less than 100 watts which does not result in significant amounts of xenon or samarium being produced in the core. ,
5. Problem A-019 We feel this is a good question with only one point of confusion. The IJfR-10 reactor would never operate for 5 consecutive days due stafravailability or argon-41 production. We would like to see the phra>e, "5 consecutive days ", replaced with, "8 ,

consecutive hours", if this question is used on future exams for this facility.

6. Problem B-012 We feel this is a good SRO question, but we do not require our RO candidates to know the Tech. Spec, basis. We would like to request that this question be removed from-the RO candidate's exams.
7. Problem B-018 .

We feel that the word "large" leads one to the emergency actions associated with a major fire not a minor fire. The key indicates that the correct answer for this question _was (A). This is the correct emergency response for a minor fire. We feel that the correct answer for this particular scenario is (D). (see also page 3 of the Operations-Abnormal and Emergency Procedures)

8. Problem C-020 We feel the answer in the key, (D), is incorrect. On page 14 of the Facility Information, the first sentence states, "The core needs 9 dummy plates to limit the calculated excess reactivity to 0.5% Ak/k, or less." For this reason we feel that selection (C)is the correct answer.

RESOLUTION OF FACILITY COMMENTS QUESTION A005: Comment accepted.- Question will be deleted from the examination. QUESTION A0ll: Comment accepted. "B" will be accepted as the correct answer. QUESTION A012: Comment not accepted. How control rod motion affects reactivity through the six-factor formula (and hence changes K eff) is fundamental. QUESTION A015: Comment noted. No action required. QUESTION A019: Comment noted. No action required. QUESTION B012: Comment not accepted. Facility procedures allow an R0 to operate the ' reactor without the direct supervision of an SR0 (who may be off-site),_ hence R0s should know Technical Specification bases. QUESTJON B018: Comment t.ccepted. Answer key typographical error. QUESTION C020: Comment accepted. Answer key typographical error.
