Subject:

NRC Examination Cc:nments

Dear Mr. Wilson:

The written exams adminis'tered on December 16, 1985, had a significant number of " completion test" items (fill in the blank).

The structure of the questions was generically poor.

There should be only one blank per item with the blank at the end of the item.

Statements taken directly from texts should be avoided; statements taken out of context are often ambiguous.

It is difficult to construct completion items that have only one correct answer and are unambiguous.1 SENIOR REACTOR OPERATOR WRITTEN EXAMINATION C0lGENTS s '

Comment #1 IQuestion 5.07(B)]

Question expects student to. predict Xenon response (magnitude) from a transient condition.

Students were provided with equilibrium curves.

Reconsnendation #1 1

Increase acceptable answer to 3300 +1000 pcm/-500 pcm.

Consnent #2 IQueetion 5.07(D)

Question states that peak Xenon can be overcome and provided data indicates it cannot be overcome.

Recommendation #2 Delete question.
