Dear Mr. Case:

We have reviewed your letters and the enclosed questionnaires.

From the on-set of ste~ generator problems we have provided all relevant infonnation on de-sign, operating conditions, inspection results, and operating experiences.

As acknowledged in your letters, a majority of the information requested has already been submitted.

The effort that would be required to complete the questionnaire would result in delays of high priority' projects being handled by our staff. Since this information is in the hands of your staff, we ask that you refer to it to de-termine whether it will satisfy your needs.
