Effluent and Environmental (Radiological) Information Liquic effluents from the TMI site releasec to the Susquehanna River after processing, were cade within the reculatory limits and in acccrcance min N:.C requirenents and City of Lan:cster Agrecr.ert.
During the period October 7, 1982, through October 14, 1982, tne effluents contained no detectable radioactivity at the discharge point and individual effluent sources, which originated within Unit 2, contained no detectable radioactivity.
- Uncertainties exist as to the exact location and accuracy of these readings.
- The primary water level is below the hot leg temperature sensors.

'Middletown 21 Yorkhaven 22 TMI Observation Center 24 The EPA Middletown Office has not received the environmental Kr-85 for the samples which were taken subsequent to September 24, 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 period from October 6, 1982 through October 14, 1982.

On October 8, 1982, two Unit 2 reactor coolant samples were shipped to the Babcock and Wilcox Lynchburg Research Center, Lynchburg, Virginia.
On October 11, 1982, two Unit 1 solidified evaporator bottoms were shipped to U.S. Ecology (Hanford Burial Site), Richland, Washington.
On October 12, 1982, two Unit 2 25-ml reactor coolant bleed tank "A" liquid samples were shipped to Westinghouse Hanford Company, Richland, Washington.

On October 13, 1982, two Unit 1 solidified evaporator bottoms were shipped to U.S. Ecology, Richland, Washington.

On October 14, 1982, ene Unit 1 solidified evaporator bottom, and nine Unit 1 and three Unit 2 LSA waste containers were shipped to U.S. Ecology, Richland, Washingten.
On October 15,1982, 77, drums containing contaminated laundry from Units 1 and 2 were shipped to Interstate Uniform Services, New Kensington, Pennsylvania.
Major Activities 1.
Submerged Demineralizer System (SDS).
SDS completed processing Batch No. 37 (approximately 5,000 gallons of miscellaneous letdown water) on October 7,1982 and is presently in standby status.
2.
EPICOR II. The EPICOR II system is presently in standby status.
3.
Reactor Building Entries.
Four reactor building entries were conducted during the week of October 10, 1982.
(Reactor building entries are typically scheduled on Monday, Wednesday, and Friday with makeup entries on Thursday.)
The ongoing flushing of reactor building interior surfaces has added approximately 60,000 gallons of processed water to the reactor building sump. Thirty thousand gallons of this water have been subsequently transferred to the SDS feed tanks for reprocessing.
Flushing of the reactor building dome has been comoleted.
The current decontamination effort is focused on remote spraying below the 305 ft. elevation and a manual decontamination of the polar crane.
In conjunction with these decontamination activities, the closed circuit television inspection of the 282 ft. elevation has continued.
A prominent " dirt ring" approximately one foot wide was visible on vertical surfaces. The elevation of the " dirt ring" appears to correspond to the elevation of the reactor building high water level (291 ft.).
An examination of the 282 ft, floor surfaces was masked by apprcxinately four inches of water wl)ich accumulated in the reactor building basement frcn decontamination activities.
The water appearec re'atively clear, i
but its cepth distorted the view of the floor surface.
An inspecticn of the cactor coolant drain tank cubicle,s.hich included an inspection of the rupture disk discharge pipe, did not identify any component damage.
l In addition to decontamination, the following reactor building activities are scheduled for the remainder of October:
l l
A second attempt to uncouple the three leadscrews still coupled to their control rod spider assemblies, l
Temporary power installation to the polar crane, and l
Preparation of work packages for testing the polar crane motors.

EPICOR 11 Prefilter Shipment Status.
The EPICOR 11 PF-2 liner, which was shipped from THI on October 7,1982, arrived safely at the Idaho National Engineering Laboratory (INEL) on October 12.
No prefilter shipments were d'
made this week because of delays in cask availability.
Two EPICOR II I
shipments are scheduled next week:
PF-7 on October 20 and PF-8 on October 21, 1982.
This schedule is predicated on having a HN-200 cask available from Hittman Nuclear and a CNS-8-120 cask returned from IddL.
5.
TMI Aerial Radiological Survey't The aerial radiological survey of the Three Mile Island area has been tentatively scheduled to'begin on October 20, 1982. is the October 14, 1982 NRC press release that describes the survey.

5 Future Meeting 1.
On October 29, 1982, Lake H. Barrett will meet with Friends and Family of 3,.
TMI to discuss various TMI-2 issues.
2.
On November 9,1982, the NRC Commissioners will hold a public meeting 12r discuss the potential restart of TMI Unit No. 1.
Further detail's regarding location and local contact for public statements will be included in a press releases'when they become available.
3.
On November 17, 1982, the Advisory Panel for the decontamination of TMI Unit 2 will hold a meeting --open for public observation-- to discuss the current status of cleanup efforts and the disposition of processed water.
The meeting will take place at the Holiday Inn, 23 South Second Street, Harrisburg, Pennsylvania, from 7:00 to 10:00 PM.

I AIRCRAFT TO PERFORM BACKGROUND RADIATION SURVEY AROUND THREE MILE ISLAND NUCLEAR PLANT IN PENNSYLVANIA A blue and white helicopter will fly a routine radiological background
~
survey at low altitudes over a 25 square-mile' area surrounding the Three beginning Mile Island Nuclear Power Plant near Goldsboro, Pennsylvania, chout October 20, 1982, and ending about 10 days to two weeks later.
The U.S. Department of Energy (DOE) will perform the survey as part of n cooperative effort with the Nuclear Regulatory Commission (NRC) to conduct an ongoing research and environmental radiation monitoring program.
The DOE has conducted similar surveys around many facilities in the United States for more than 20 M ars.
The last cuch survey of the Three Mile Island area was done in 1976.
An EG&G, Inc., crew from the firm's Washington, D.C., Aerial Measure-ments Operations Office will operate tho DOE-owned helicopter.
The crew will map the natural terrestrial radiation profile of the area surrounding the Three Mile Island Nuclear Power Plant.
The helicopter will fly during the day at an altitiude of 150 f66t.
Flight schedules will depend on weather conditions.
All flights will be coordinated with the Federal Aviation Administration.
