In Reference (a), the NRC staff requested additional information from Commonwealth Edison (ComEd) to support the review and approval of ComEd's TSUP project. Regarding TSUP Section 3/4.8, the NRC requested further evaluation by ComEd concerning the comparison of current requirements and the proposed TSUP requirements. ComEd submitted TSUP Section 3/4.8, "Plant Systems," to the NRC staff on September 10, 1993 (Reference (b)). The purpose of this letter is to respond to the NRC staff's RAI for TSUP Section 3/4.8 and supplement the information previously provided in the Reference (b) submittals. The information provided in this letter provides a comprehensive evaluation
, between current requirements against those proposed in TSUP and provides a discussion demonstrating the acceptability of any apparent deviations. Other portions of ComEd's response to the RAI regarding other Sections of TSUP will be forthcoming under separate cover.

Attachment A and B to this letter proVides ComEd's response to NRC staff Generic Question No. 1 (supplemental significant hazards evaluation for TSUP 3/4.8) and Generic Question No. 2. Our response to Generic Question No. 2 includes supplemental information regarding proposed TSUP Section 3/4.8 as well as additional information regarding the comparison to current Technical Specification requirements. Attachment C provides ComEd's response to the NRC staff RAI regarding specific issues for TSUP 3/4.8.
In order to most effectively implement TSUP at Dresden Station, ComEd's goal is to complete implementation of TSUP at Dresden during October, 1995. The goal for implementation at Quad Cities is February 1996.
It should be noted that the proposed TSUP Section 3/4.8 requirements are consistent with and confirm the current safety analysis as described in the UFSAR. Any changes to the UFSAR necessitated by the approval and implementation of TSUP will be incorporated into the UFSAR, where applicable.
