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 January 8,1982, through January 14, 1982, the effluents contained no detectable radioactivity at the discharge point and individual effluent sources, which originated within Unit 2, contained no detectable radioactivity.

Environmental Protection Agency (EPA) Eny'ir"ohmentil Data.
The EPA Middletown bffice has noYrede'thed thd analytical results for Kr-85 measurements'around the 1MI site from the EPA's Counting Laboratory at Las Ve' gas,.NeYada.$.When these results become available, they will be inclu ed in a* subsequent report.
(
No radiation above nomally occurring background levels was detected in any of the samples collected from EPA's air and gamma rate networks during the period from January 6,1982 l
through January 14, 1982.

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:

4 No Shipments were made by,the licensee during this reporting period.
i Major Activities 1.
Submerged Demineralizer System (SDS).
Processing of batch 16 was completed on January 10, 1982.- From January 10, 1982 to January ll,1982,
_appro' imat'ely 45,000 gallons of water,'(batch.17) Nere, transferred x
from the reactor building sump.. The total a' mount of water transferred s
'from the reactor buildirg sump as of January 15,1982,'is approximately 445,000 gallons. ' The SDS will commence processing batch 17 c
following modification of an underwater tool used to move the SDS vessels from the processing position to underwater storage.
The modification is expected to be completed around January 20, 1982.
SDS Performance parameters for batch 16 a're enclosed.
2.
EPICOR II.
EPICOR II processing of SDS effluent continued this week.
The latest performance parameters,for EPICOR II are enclosed.

Borated Water Storage Tank Leak. On Wednesday, January 13,1982, a leak was discovered from a 3/8 inch instrument line connected to the Borated Water Storage Tank (BWST).
It is estimated that the leak may have caused as much as 50 gallons of radioactive water to leak onto the ground.
The tank contained a mixture of pre-accident Unit 2 water, a substantial amount of water transferred from the Unit 1 BWST in March 1979, and some processed auxiliary building water from EPICOR II.
The predominant radionuclides in the water include:
Cs 137 3.7 x 10-4 uCi/ml Cs 134 1.1 x 10-4 uCi/ml Co 60 1.3 x 10-5 uCi/ml After the leak was repaired, workers began removing the contaminated soil from under the faulty pipe.
The groundwater around the BWST is monitored by several sampling stations which were installed as part of the site groundwater monitoring system. Water samples from selected groundwater monitoring points were taken on Thursday to determine the extent of the contamination.
Based on the cold ambient temperatures, the small quantity of the spill and the relatively low activity, it is not expected that the activity resulting from the leak will be detectable away from the immediate vicinity of the pipe.
The 3/8 inch line failure is attributed to the cold weather.
The instrument line apparently froze and cracked after the electric heat tracing system which normally heats the line failed.
4.
Reactor Building Entries. Reactor building (RB) entry 29 was completed on Thursday, January 14, 1982.
The major tasks performed during the entry included testing of the NI-2 neutron detector cables, survey of the electric caole path for the polar crane power lift, and additional examination of clues to evaluate the nature of the hydrogen burn during the March 1979 accident.
The start of the gross decontamination experiment, which is a prerequisite activity for, polar crane repair and reactor disassembly, has been delayed to February 1982.
The decontamination experiment was originally scheduled to be completed in December 1981.
Del ays have been experienced in completing prerequisite activities to support the decontamination experiment.
Specifically, two,10 inch flanges which are to be installed at both ends of a spare RB penetration to route decontamination water into the RB have not been built due to engineering delays.
It is anticipated that the flanges will be built and installed in time to support the decontamination experiment in February 1982.
The next RB entry is scheduled for the last week in January.
Following the decontamination experiment, the licensee plans to reduce the frequency of RB entries because of financial limitations.
