Effluent and Environmental (Radiological) Information 1.
Liquid effluents from the TMI site released to the Susquehanna River after processing, were made within the regulatory limits and in accordance with NRC requirements and City of Lancaster Agreement dated February 27, 1980.
During the period November 20, 1981, through December 3,1981, the effluents contained no detectable radioactivity at the discharge point although individual effluent sources which originated within Unit 2 contained minute amounts of radioactivity.
Calculations indicate that less than two hundred thousandths (0.00002) of a curie of tritium was discharged.
Resul ts Environmental Protection Agency (EPA) Environmental Data.

The EPA Kr-85 samples experienced a shipping delay; results Area Kr-85 concentrations will be reported were not available.

fio radiation above normally occurring background levels was detected in any of the samples collected from the EPA's air 18, 1981, and gamma rate networks during the period from flovember through December 1,1981.

On Monday, November 23, 1981, four Unit i liners of solidified evaporator bottoms were shipped to Chem Nuclear Systems Inc.,
Barnwell, South Carolina.
On Wednesday, November 25, 1981, 50 drums of contaminated laundry were shipped to Tri-State Industrial Laundry, Utica, New York.
30,1981, a Unit 2 dewatered resin liner On Monday, November (EPICOR 11 liner K-3) was shipped to U.S. Ecology, Hanford, Washington.
On Tuesday, Dacember 1,1981, a Hittman radwaste mixing head used at Unit I was shipped back to Hittnn Nuclear Development Corporation, Col umbia, Maryland.
On Wednesday, December 2,1981, a Unit 2 deeatered resin liner (EPICOR 11 liner F-13) was shipped to U.S. Ecology, Hanford, Washington.

idajor Activities 1.
Submerged Demineralizer System (SDS).
Processing of batch number 11 was completed on November 28, 1981.
During November 29,1981, to December 1,1981, approximately 50,000 gallons of reactor coolant bleed tank water were transferred to the SDS feed tanks in the fuel handling building.
Processing of batch number 12 commenced on December 2,1981.
To date, approximately 295,000 gallons of reactor building sump water have been transferred from the reactor building sump and processed.
Transfers of reactor building sump water ir expected to continue following the processing of two batches (12 and 13) of reactor coolant bleed tank water.
SDS performance parameters for batch 11 are attached.
2.
EPICOR II.
Processing of SDS effluent through the EPICOR 11 tystem continued this week.
Approximately 285,000 gallons of reacter building sump water have been polished.
Recent performance parameters for EPICOR II are attached.
3.
Reactor Buildine Entries.
Reactor building (RB) entry number 23 was completed on Thursday, December 3,1931.
This was the e cnth entry in support of the gross decontcmination experiment.
