Dear Sir:
/
Three Mile Island Nuclear Station, Unit 2 (TM1-2)
Operating License No. DPR-73 Docket No. S'J-320 Submerged Demineralfzer System This letter forwards our revised SDS Technical Evaluation Report.
The revised TER incorporates changes necessitated as a result of our continuing re-evaluation of our decontamination plan.
The primary change described in the use of EPICOR-II as a polishing system for SDS ef fluent treatment. EPICOR-II utilization will provide for enhanced decontamination factors, primarily for the recalcitrant species and removal of trace radionuclides. Use of EPICOR-II has enabled the effective decontamination of 500,060 gallons of radioactively contaminated water in the Auxiliar -
Building.
Your letter, NRC/TMI-80-145, dated November 7,1980, requests that we revise the SDS TER and forward c;mments and concerns. We will respond to those comments and concerns separately in the very near future.
We believe that the SDS, followed by EPICOR-II as an effluent polishing system, represents a viable and effective method for decontamination of the containment sump water and the RCS water.
Your appraval to operate this sytem is requested.
Sincerely, j [
