SUMMARY- 0F GENERIC DEFICIENCIES NOTED ON ORAL / SIMULATOR EXAMS: Reactor Operator (RO) candidates were not familiar with locations of reference data / procedures in the control roo RO candidates were slow to locate some of the supervisory switches and specific meter parameter . SUMMARY OF GENERIC DEFICIENCIES NOTED FROM GRADING OF WRITTEN EXAMS: R0 candidate knowledge of principles of nuclear power plant operation, thermodynamics, heat transfer and fluid flow is good, More than one-half of the candidates lacked some knowledge in the following areas: The effects of core burnup on the Moderator Temperature Coefficien The functions / purposes of the Emergency Diesel Generator Blowe The closing motive forces for Main Steam Isolation Valves when the plant is at powe The actions an operator is to immediately perform if the " Valve 730 or 731 not fully open" annunciator is receive The purpose of steam dump interlock The reason for the precaution of not adding hydrazine until the oxygen content in the volume control tank is less than 2%. The criteria for approval of temporary changes to plant procedure The people that are required to authorize the installation of a jumper that defeats a trip or nuclear safety circuit in a non-emergency situatio _ _ _ _ _ _ _ _ _ _ _ _

5. WRITTEN EXAMINATION REVIEW At the conclusion of the written examination, the examiners met with the following facility personnel to review the master written examinations and answer keys to identify any inappropriate questions relative to plant specific design and to e.nsure that the questions elicited the answers in the key and that they reflect current plant conditions: B. Ray, Nuclear Training Coordinator C. Embry, Nuclear Training Specialist - C. Lambert, Nuclear Training Specialist E. Diamond, Nuclear Training Specialist R. Robenstein, Training Specialist Verbal comments were received from the reviewers. The plant specific references that supported these comments were verified by the examiners and the comments were appropriately incorporated into the answer key during the review. No other verbal nor written comments were received by the examiners. Significant changes are listed in Attachment . PERSONNEL PRESENT AT EXIT INTERVIEW: NRC Personnel P. Koltay, Resident Inspector D. Coe, Reactor Engineer (Examiner) NRC Contractor Personnel A. Vinnola, EG&G, Idaho P. Isaksen, EG&G, Idaho R. Sailor, EG&G, Idaho Facility Personnel J. Brons, Resident Manager J.

. SUMMARY OF NRC COMMENTS MADE AT EXIT INTERVIEW:
Individuals who clearly passed the operating examination were identifie Significant knowledge and ability weaknesses noted during the operating examination were presente The following general comments were also presented by the examiners: isndidates had d;fficulty locating specific procedures within a inder because .he procedures had misplaced pages and were not indexed like the procedures located in the control roo The examiners expressed concern about the dissimilarities between the Indian Point 2 simulator used for examinations and the Indian Point 3 control room, because some of the candidates were slow to locate switches and meters that were either in dissimilar locations or were not identical between the two units. The examiners stated that the NRC Region I Office would follow up on this item.
