3. Written Examination and Facility Review:

1 The written examination was administered to the candidate on December 14, 1987.

At the conclusion of the written exam,-Dr. Whittemore was given copies of the written exam for review. The conments made by Dr. Whittemore at the conclusion of the review are included in the attachment (1). These comments were discussed with the staff and appropriate changes were made to the exams prior to the grading of the exams.

4. Exit Meeting The Chief Examiner met with the facility representative denoted in Paragraph 2 on December 14, 1987. The examiner discussed the findings to that point and the examination process.

Resolution of Facility Coinments Facility Comment: L-11 "This is a legitimate question but your key answer is only partially correct. A better answer is given here with the addition underlined.

' Prevent withdrawal of more than one control ro at a time.

Prevent application of air to transient rod (s) unless all standard rods are fully inserted and moveable cylinders are fully inserted.'"

Resolution:

Agreed, will change key.

Facility Comment: L-15 "The key answer to L-15 was correct until well into 1987 when NRC unilaterally issued a Technical Specification change for 9.1.1 as follows:

The operating power level of the reactor shall not be intentionally raised above 1500 kilowatts except for pulsing operations."

Resolution:

The examiner will change the key, and take into consideration any assumptions used by the candidate.
