U-0583 ILLINDIS POWER 00MPANY L30-82(12-13)-6 500 SOUTH 27TH STREET, DECATUR, ILLINOIS 62525 December 13, 1982 Mr. A. Schwencer Licensing Branch No. 2 Division of Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Schwencer:

References:

(1) Letter, W. C. Gerstner to D. G. Eisenhut November 30, 1982, " Containment Purge" (2) Memorandum, J. H. Williams to Harold Bernard July 26, 1982, " Meeting with Illinois Power Company on Containment Purge" Clinton Power Station Unit 1 Docket No. 50-461 Containment Continuous Vent & Purge System The purpose of this letter is to follow up on the matter of the Clinton Power Station containment vent and purge system as we stated we would do in Reference (1). It is our conclusion that we should proceed immediately with design changes to the existing CPS systems to implement a Grand Gulf-type configuration as described in Reference (2).

We wish to meet with the Staff in early January to review the basis for redesign as discussed in a telephone conversation of today between L. Ruth, J. A. Kudrick, and W. R. Butler of the NRC and E. W. Kant of IP. We propose January 11, 1983, for this purpose.

This matter has been one of the most difficult questions in our licensing reviews. I trust that the extra time required to

reach this decision has not caused you unnecessary inconvenience.

l j Sincerely,

).Y G. E. Wuller
