March 21,1994 Mr. Williarn T. Russell, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington D.C. 20555 Attn.: Document Control Desk

Subject:

Quad Cities Station Units 1 and 2 Resolution of Systematic Evaluation Program Issues for Quad Cities Station NRC Docket Nos. 50-254 and 50-2f5

Reference:

(1) J.L. Schrage to USNRC letter dated September 18,1992 (2) J.M. Taylor to J.J. O'Connor letter dated November 17,1993 Mr. Russell, r

in the Reference (1) letter, Commonwealth Edison (CECO) discussed the planned

! efforts to address the results of the Dresdon Station Unit 2 Systematic Evaluation Program (SEP) at Quad Cities Station. CECO indicated that these planned efforts consisted of developing action plans to: 1) evaluate and prioritize recommended actions in light of current planned work; 2) implement appropriate recommendations; and 3) identify alternative recommendations. CECO stated that the schedule for the development of action plans was August 31,1993.

In the Reference (2) letter, the NHC transmitted the Diagnostic Evaluation Team (DET) Report for Quad Cities Station. This report indicated that, as of September 24, 1993, the action plans to address the Dresden 2 SEP issues at Quad Cities had not been completed. This letter transmits the status and schedule for completion of the action -

plans.

CECO has completed the development of action plans at Quad Cities Station to evaluate and prioritize recommended actions associated with seventeen Dresden Station .

Unit 2 SEP issues at Quad Cities Station. Of these seventeen nction plans, CECO has completed the actions associated with five of the action plans. The Attachment to this letter lists the five SEP Topics with completed Action Plans, and the Action Plans for the remaining twelve SEP Topics (including the expected completion dates). CECO will verbally communicate any changes to the Action Plans (including the expected completion dates) with the NRR Project Manager.
