EXAMINATION QUESTION RO #3 l LICENSEE COMMENT l The question asked how was a procedure change procedurally conveyed to members of i the operating crew. Procedure BwAP 350-2 Rev 6," Daily Order Book," requires only the Shift Manager (SM) to read and initial the Daily Orders and was responsible to ensure appropriate operating personnel were notified, as necessary. The question distractor (A) was incorrect because a "memn" was not issued to all crew personnel and the SM may not be the person who places the information in the Daily Order Book.
! Distractor (B) was incorrect because the SM was not necessarily informed by memo and ! it wasn't proceduralized. Distractor (C) was incorrect because individual operators were briefed by the SM (by procedure). Distractor (D) was also incorrect because the Shift Operation Supervisor does not make an announcement at the shift briefings; it was the SM who does. Therefore, there was no definitive correct answer.
Recommend deleting the question.
) NRC RESOLUTION The comment was accepted and the question was deleted.
Question His. tory No chales were made to the original question as submitted.
2.
EXAMINATION QUESTION RO # 10 LICENSEE COMMENT The question asked the condition for entry into a fuel handling accident given the plant conditions. The entry condition for distractors (B) and (D) directly apply. No procedural differentiation or hierarchy for a backup indication or report to cause the immediate actions to occur. BwOA Refuel-1, Rev. 54, symptoms / entry conditions include: observed dropping of, or damage to, a fuel assembly; observed dropping of an object or a fuel assembly; observed from a potentially damaged fuel assembly. Any of the procedure entry conditions necessitate use of BwOA Refuel-1. Step 3 only requires one of the alarms (AR011 or AR012) in order to execute actions. Expected, conservative operator actions would be to initiate or actuate Unit 1 Containment evacuation alarm when RE-AR012 alarms, followed by a report from personnel in containment or corresponding rise on a duplicate monitor.
Recommend changing the answer key to accept both (B) and (D) as correct answers.
NRC RESOLUTION The comment was accepted, and both (B) and (D) was noted as correct answers.
Question History No changes were made to the original question as submitte __ - -...= - _ . Enclosure 2 , 3.
EXAMINATION OUESTION RO # 13 LICENSEE COMMENT The reference cited for this question / answer was BwAP 380-2, Rev. 6E1. This was not valid for the plant conditions stated in the question. This procedure applies for alarms that are in alarm condition >1 shift and for power levels > P-8 set point (30%). The only applicable standard that applies was NOD OPS DEPT STD-BWD which states that "the SER shall be utilized to verify the exact cause of each annunciator..." and " announcement of repetitive alarms... are not required with the concurrence of the Unit Supervisor...," BwAP 300-1, Rev.19E1, also applies, giving generic good operating l practice guidance to "believe their instruments until the indications are proven to be false." OPS DEPT STDS and BwAP 300-1 are governing guidance.
Recommend changing the answer key to eccept both (A) and (C) as correct answers.
NRC RESOLUTION The comment was accepted, and both (A) und (C) was noted as correct answers.
Question History: No changes were made to the original question as submitted.
4.
EXAMINATION QUESTION SRO # 54 LICENSEE COMMENT Candidate answered question correctly for current Braidwood plant configuration and procedures in effect. Automatic actuations in combination with designated SG levels would have resulted in both auxiliary feedwater pumps running. The student was advised to use current plant configuration, procedure references and setpoints for the purposes of this examination (" freeze" point of training and evaluation process). This was clarified to him by the ILT group lead in preparation for this examination. The proctor at the point of administering the examination directed use of "NEW" SG numbers (setpoints, data) based on the belief that the student had received this specific training (which he had not). The student had received SG RO training which characterized the modification / purpose, not the setpoints/ procedure specifics. Candidate had not attended licensed requal training v1.ich revi3wed abnormal and emergency operating procedure changes relative to new set points. He was in formal ILT remediation at this point.
These changes are not in place yet. He will receive this training during September and October 1998 as part of preparation for license activation.
Recommend changing the answer key to accept choice (A) as the correct answer.
NRC RESOLUTION The comment was NOT accepted, and the correct answer remains as (B). The original examination question, with the associated answer key and reference based on the New i SG information, was submitted to the NRC. The exam documentation with the NRC Quality Assurance checklist (ES 401-6), original submittal and subsequent revision, was , l accepted and signed by the Braidwood Training Department as part of the NRC exam submittal. The licensee had several opportunities to review, verify, and correct the , written examination prior to final submittal to the NRC for exam administration.

. Enclosure 2 Additionally, the licensee's exam development group specifically noted that the examination referenced the new SG and approved by the Braidwood facility.
' Qgestion Historv Minor wording change on the question stem was made. Changed some information in the question stem that potentially gave information for a previous question. Also, the deleted information was not needed to answer the question. Deleted the word "ONLY" from two distractors, to eliminate " specific determiners" per NUREG 1021, Appendix B.
Remainder of the question stem, distractors, and answer were left the same.
5.
EXAMINATION QUESTION RO # 96 , ' LICENSEE COMMENT The question stated that RCS activity was increasing due to corrosion product activation and to identify the effects of placing the cation bed demineralizer in service.
Procedural guidance discriminates the purposes of each ion bed. The cation bed was efficient at removing Lithium which contributes to low pH and further corrosion products
and associated activity. BwOA PRI-4 (High Reactor Coolant Activity) provides guidance / direction for action to be taken in the event of high RCS activity, it directs that the standoy mixed bed demineralizer be placed in service NOT the cation demineralizer.
BwOP CV 8 references use of the Cation Demin for the reduction of pH or fission products, (not for the purpose of reduction of activated corrosion products). Based on procedural guidance and use, the cation demineralizer would not be placed in service, substantiating (A) as a correct answer; (B) would be correct based on the physical properties of the demineralizer, not accounting for procedural guidance and use.
Recommend -changing the answer key to accept both (A) and (B) as correct answers.
NRC RESOLUTION The comment was accepted, and both (A) and (B) was noted as correct answers.
Question Histort No changes were made to the original question as submitted.

If it fails high Tref goes to maximum value (581*F) and results in rods being withdrawn to match Tave to Tref. PR failure high compares the rate of change of reactor power to the rate of change of turbine power. Initially high rate of change during failure but rapidly the rate of change falls to zero and so rods may initailly begin to insert but quickly stop motion with no more rate of change. Auctioneered high Tave is used and Tcold failing low will remove this input (if prevolusly auctioneered high). Tref failing low will cause rods to move inward to match Tave to Tref.
