Dear Sir:

Three Mile Island Nuclear Station, Unit II (TMI-2)

Operating License No. DPR-73 Docket No. 50-320 Proposed Program for Auxiliary Building Sump and Associated Tanks Decontamination Enclosed please find the Decontamination Plan discussed in our letter dated December 21, 1979, GQL 1509 (Item #13).

The Auxiliary Building sump and associated tanks decontamination will take place over the remainder of 1980.

The internal decontamination of these tanks and sump will be performed in accordance with approved procedures that will be submitted for NRC ' review and approval.

The proposed schedule for accomplishing this decontamination effort will require three hundred (300) working days to accomplish, based on logical steps-and manpower availablilty.

The schedule is dependent on the availability of EPICOR II processed water for flushing systems, tanks ar.d components and is a best case p1m. based on the assumption that no plating of contaminants has taken place in the tanks and that processed water flushing and filtering will remove all contamination.

The processed water is also needed to wash down exterior surfaces inside the tank cubicles prior to entry for tank decontamination.

With the exception of the Auxiliary Building sump and sump tank, the amount of decontamination required in the tanks will be determined as each system is finshed and an internal inspection of the tank has been accomplished.

This internal inspection will determine the extent of residual contaminatian, remaining inside, that must be removed.

It is presently planned to circulate the tank water through filters to remove the tank residuals.

The system and the operating techniques used will be supported by approved procedures.
