Reference:

Letter, S. H. Howell to J. G. Keppler, Midland Nuclear Plant -

Unit No.1, Docket No. 50-329; Unit No . 2, Docket No. 50-330; '

NI/RPS Grounding Concern, Howe h8-78, dated April 6,1978.

The referenced letter was an interim report. This letter is also an interim report, since analysis to determine'the appropriate corrective action is continuing. The review of the condition, as reported by B&W, supported the conclusion that the significant deficiency is applicable to Midland.

The schedule for procedure preparation for the Midland NI/RPS is being revised to include development of a procedure to test for a " loss of ground condition" in anticipation that this will be the appropriate cor ective action. Consumers Power will follow the actions of E&W and the other utilities to benefit from their experience in implementing corrective action on the affected plants.

Another interim report vill be supplied by August 31, 1978.
