Subject:
Quad Cities Station Units 1 and 2 Proposed Amer.dments to Appendix A Technical Specifications to DPR-29 and DPR-30 Concerning The Containment Cooling Mode o f the RHR System NRC Docke t No s. 50-254 an d 50-26 5 References (a):

J. Rausch letter to H. R.
Denton dated December 3, 1981.
(b):
T. J. Rausch letter to H. R. Denton dated December 14, 1981.
(c):
R. Bevan letter to L. O. DelGeorge dated December 18, 1981 ( Am. 7 5 & 6 8).
Dear Mr. Denton:
Reference (c) amended the Quad Cities Station Unit Nos.1 and 2 Operating Licenses Nos. DPR-29 and DPR-30 to allow the "A"
loop of the Residual Heat Removal (RHR) heat exchangers on each unit to be fed from the RHR "A" and "B" Service Water pumps from Unit 2 via a cross-tie line.
These amendments allowed continued operation of both units using the cross-tie until June 1, 1982, at which time it was anticipated that modification and repair of the Unit 1 loop "A" service water line could be completed.
The modification consists of a complete above ground rerouting of the 16 inch, safety-related and seismically qualified service water piping from the turbine building condensate pit to the reactor building basement HPCI room.
Due to the complexity of this modification, and the tight work schedule, we have determined that additional time will be required to complete this modification.
Although we expect to have the modification completed in all respects except for final installation of seismic restraints by June 6, 1982, minor Technical Specification changes will be necessary to allow continued operation of the units.
