- 1. - -Effluent and Environmental (Radiological) Information Liquid effluents from the TMI site released to the Susquehanna River after sampling and monitoring were within the regulatory limits and in a'ccordance with NRC requirements and City of Lancaster Agreement.
,During the period December 31, 1982, through January 6, 1983, the effluents contained no detectable radioactivity at the discharge point althokgh inGi^ dual effluent sources which originated within Unit 2 contained mW u e amounts of radioactivity.
Calculations indicate that less than one ten-millionth (0.0000001) of a curie of cesium and less than 20 millionths (0.000020) of a curie of tritium were discharged.
o Uncert'ainties exist as to the exact location and accuracy of these readings.

Environmental' Protection Agency (EPA) Environmental Data i
I The EPA Middletown Off. ice has not received the environmental Kr-85 results for the samples which were taken subsequent to December 10, 1982 from the EPA's Counting Laboratory at Las Vegas, Nevada. These results will be included in a subsequent report.-
No radiation above normally occurring background levels was detected, in any of the samples collected from the EPA's air and gamma rate networks during the periods from December 29, 1982 through January 6, 1983.
- 3. ' NRC Environmental Data Results are from NRC monitoring of the environment around the TMI site.
The following are the NRC air sample analytical results for the onsite continuous air sampler:

Licensee Radioactive Material and Radwaste Shipments On January 3,1983, one box containing a one liter liquid sample taken from the Unit 1 waste evaporate condensate storage tank was i
mailed to Radiation Management Corporation, Philadelphia, 4
On January 3, 1983, 78 drums containing contaminated laundry from Unit 1 and Unit 2 were shipped to Interstate Uniform Services, i
New Kensington, Pennsylvania.
On January 6, 1983, one box containing Unit i liquid samples was mailed to Radiation Management Corporation, Philadelphia, Pennsylvania.
On January 6, 1983, one drum containing three Unit 2 control rod drive mechanism (CRDM) electrical cables was shipped to Westinghouse Hanford Co., Richland, Washington.
On January 6, 1983, one drum containing one Unit 2 CRDM electrical cable was shipped to Westinghouse Hanford Co., Richland, Washington.
On January 6, 1983, one drum containing eight 250-milliliter once-through-steam-generator (OTSG)flushtestsamplesfromUn'itI was shipped to Babcock and Wilcox, Lynchburg, Virginia.

On January 7,1983, one box containing various smear and swipe samples from Unit 1 was shipped to Babcock and Wilcox, Lynchburg, Virginia.
On January 7,1983, one drum containing water samples taken from a Unit 1 OTSG and miscellaneous swipes was shipped to Babcock and Wilcox, Lynchburg, Virginia.
I On January 7,1983, a CNS-8-120 (type B) shipping cask containing EPICOR 11 prefilter No. PF-50 was shipped to Idaho' National Engineering Laboratory, Scoville, Idaho.

On January 7, 1983, 101 drums containing contaminated laundry from Unit 1 and Unit 2 were shipped to Interstate Uniform Services, New Kensington, Pennsylvania.
Major Activities 1.
Submerged Demineralizer System (SDS). The SDS performance parameters for Batch 6 of reactor coolant system (RCS) water (which comprised SDS Batches 39 and 40), are included in Attachment 1.
RCS Batch 6 was completed on December 27, 1982.
Processing of SDS Batch 41 (48,000 gallons of reactor building sump water) began January 4, 1983.
It was interrupted to allow the EPICOR II processing of the water from the "A" once-through-steam-generacor.
In addition, 40,000 gallons of RCS water, which had gone through the
" feed-and bleed" process, have been staged in the "C" reactor coolant bl.eed tank to await SDS processing.
2.
EPICOR II.
EPICOR 11 processed 2,000 gallons of water from the "A" (The performance contaminated drain tank (CDT) on January)5,1983.The processing of the CDT parameters are included in Attachment 1.
water was necessary to allow the drain down of water from the "A" once-through-steam-generator (OTSG)tothecontaminateddraintank. The OTSG transfer is scheduled to begin on January 7,1983; it will consist of approximately 35,000 gallons, which will then be processed by EPICOR II.
Subsequent to this, EPICOR II will begin processing of SDS Batch 41.
3.
Reactor Building Entries.
Four reactor building entries were made during the first week of January. The decontamination of exposed reactor building surfaces is being reevaluated after post decontamination surveys of horizontal surfaces indicated that surface recontamination was
- occurring.
Preliminary data indicate that the recontamination is occurring at rates which significantly reduce the long term effectiveness of the original decontamination.
Experiments have been devised to determine the recontamination mechanism. While the surface recontamination phenomenon is being investigated, remote decontamination of walls on the 282 ft. elevation is continuing.
Decontamination of the reactor vessel service structure and the refueling pool area commenced on Friday, January 7, 1983.

Polar crane refurbishment is proceeding without major obstacles.
Crane inspection by an NRC contractor is scheduled for mid-January. The crane j
load test is scheduled for late February.
l Lack of available man-rem for certain personnel in the specialized work force has been identified as a potential limiting factor in the projected work scheduled during the first two quarters of 1983.
The licensee has procured shielding material for use on the high radiation sources in the.
j reactor building, and it is scheduled for installation in January. The -
effectiveness of the shielding and the decontamination program will be critical factors in the progress of the reactor building recoverygffort.
Five reactor building entries per week have been scheduled during the next two' weeks.
4.
SDS Liner Shipment Preparations. The first recombiner loaded SDS waste liner, which was shipped from TMI last week, arrived safely at the DOE facility in Richland, Washington on January 3,1983. The licensee is making preparations for the next SDS shipment, which is tentatively scheduled for January 21, 1983.
The shipping preparations will be similar to those for the first shipment, including a monitoring period to demonstrate that non-combustible gas conditions will be maintained for a minimum of twice the expected handling and shipping period.
5.
EPICOR II Prefilter Shipment.
EPICOR II prefilter liner PF-50 was shipped from TMI to the Idaho National Engineering Laboratory (INEL) on January 7, 1983. This EPICOR prefilter shipment brings to a total of 17 (in a group of 49) prefilters that have been shipped to INEL. One prefilter shipment is scheduled for next week.
