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 October 9,1981 through October 15,1981, the effluents contained 'no detectable radioactivity at the discharge point and individual effluent sources which originated within Unit 2 contained no detectable radioactivity.

Environmental Protections Agency (EPA) Environmental Data.
The EPA announced on July 6,1981 that, due to a new shipping procedure for Kr-85 samples to the laboratory, the results for the Kr-85 environ-mental monitoring stations around TMI will not always be available on a weekly basis.
The NRC will report these re" Its as they become c
available.
No radiation above normally occurri cac4 ground levels was detected in any of the samples ce'
.eted from the EPA's air and gamma rate networks durino a period from October 7,1981, through October 15, 1981.
3.
NRC Environmental Data.
Results from NRC monitoring of the environment around the TMI site were as follows:
The following are the NRC air sample analytical results for the onsite continuous air sampler:

Licensee Radioactive Material and Radwaste Shipments.
On Wednesday, October 7,1981, one EPICOR II dewatered resin liner (F-2) was shipped to U.S. Ecology, Richland, Washington.
On Monday, October 12,1981, a 40 ml Unit 2 reactor coolant sample was sent to Babcock and Wilcox (B&W), Lynchburg, Virginia.
On Monday, October 12, 1981, two TMI-l liquid samples were shipped to Teledyne Isotopes, Westwood, New Jersey.
4 On Wednesday, October 14, 1981, 50 drums containing TMI-1 and TMI-2 contaminated laundry were shipped to Tri-State Industrial Laundries, Utica, New York.
On Friday, October 16, 1981, two EPICOR II dewatered resin liners (F-4 and F-5) were shipped to U.S. Ecology, Richland, Washington.

1.
Submerced ~ Demineralizer-System (SDS).
Processing of batch' number 7 -
v4 began October 19,1981, and as of October 16, 1981, 34,500 gallons cf of the 50,000 gallon bat'ch had been processed.
Processing was-interupted for approximately two days for correction of reduced flow in the auxiliary building ventilation sy:t?m.
The problem was 7ci resolved and processing of the remainde.r of batch number 7 was
~ "
resumed. As of October 16, 1981, approximately 100,000 gallons of l
reactor building sump water has been processed through the SDS. -
l
~
l On October 17 1981, an SDS zeolite vessel' loaded with 'approximately 25,000 Ci of Cs-137 and approximately 1,000 Ci of Sr-90 was successfully.
dewatered.
The NRC onsite. staff provided backshift coverage during i
the dewatering evolution.
The dewatered vessel will be used to verify the shielding capability of the shipping cask to be used to transport the SDS vessels.
This data will be used to determine if i
the vessels can be loaded up to approximately.60,000 Ci of Cs-137.
Early during the week of October 18,198h the licensee is expected to commense processing batch number 8 (another 50,000 gallons o'f f
j reactor building sump water).
p 2.
EPICOR II. Processing of the SDS effluent through the EPICOR II system continued this week except for the' two day interuption due
~
i to the auxiliary building ventilation problem as mentioned in the -
,f:ji SDS paragraph above. Another of the first stage EPICOR II liners
.. M 4
(F-6) along with one'of the second stage ' liners.(K-1) were' removed
' 7059 from the system.
Two more of the first stage liners (F-4 and F-5)'
g have been dewatered and shipped to Richland, Washington for disposal t zyj at a ' commercial burial facility.
As of October 16,.1981, approximately di;4fg:
95,000 gallons of sump water has been polished.

o fleetingAttended On Tueiday, October 13, 1981, Lake Barrett addressed the Downingtown Rotary Club and,gave an upda.te on the.. cleanup efforts at TMI and discussed the functions of the NRC.
Future Meetings 1.
The NRC's Advisory Panel for the Decontamination of Three Mile
-3 Island Unit 2 will meet October 21, 1981, in York,. Pennsylvania and November 16, 1981, in Lebanor, Pennsylvania.
At both meetings, the panel plans to discuss the current status of cleanup activities at Three Mile Island.
The October 21 meeting will be held at 7:00 PM to 10:00 PM in the Hotel Yorktown, 48 East Market Street, York.
The November 16 meeting will be held from 7:00 PM to 10:00 PM in the Municipal Building, 400 South 8th Street, Lebanon.
Both meetir.gs are open to the public.
2.
On Saturday, November 14,1981, at 8:00 PM, Lake Barrett will participate in a panel discussion at the Elizabethtown Public Library on the government's response to the TMI accident.
