/LLINDIS POWER 00MPANY IP CLINTON POWER STATION, P.o. box 678, CLINTON, ILLINOIS 61727 Docket No. 50-461 Septcznber 26, 1984 Director of Nuclear Reactor Regulation Attention: Mr. A. Schwencer, Chief Licensing Branch No. 2 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D. C. 20555 Subj ect: Clinton Power Station Unit 1 i Seismic Qualification of Equipment

Dear Mr. Schwencer:

As referenced in the Clinton SSER 2, attachment 1 is submitted and constitutes a summary update to information previously forwarded with Illinois Power letter #U-0707 dated April 30, 1984. Specific details concerning seismic qualification status for each piece of equipment are available in prelimina , form, and copies can be provided if you need them.

Of the 9.852 pieces of equipment which require seismic qual-ification 5524 are qualified, of which 1767 are installed. Expressed as a percentage, approximately 56% are qualified and 17.9% are qualified and installed. Current schedule projections indicate achievement of the 85% equipment qualified and installed on or before May, 1985.

Substantial improvement in the installation complete status is anticipated in the near term due to improvements in cable pulling and I termination progress which will complete many equipment installations. '

Illinois Power anticipates achievement of 85% qualified and installed criteria commensurate with an NRC SQRT audit by July, 1985.

Please contact us if you have any questions concerning this information.

Sincerely yours, 4.A. a ,
