g Core Cooling Mode: Cyclic natural circulation in the "A" reactor coolant system (RCS) loop via the "A" once through steam i
generator (OTSG), steaming to the main condenser, and RCS loop-A and B cyclic natural circilation to reactor building ambient.
i Available Core Cooling Modes: 0TSG "B" steaming to-the main condenser; long-term cooling "B" (OTSG-B); decay heat removal.
RCS Pressure Control Mode: Standb3 'ressure Control-(SPC) System.
Backup Pressure Control Mode: One of two decay heat removal pumps to supply pressure in conjunction with variable recirculation back to the borated water storage tank (BWST) to provide control of pressure.

Effluent _ and invironmental (Radiologic _al) Infonnation l.
Liquid effluents from TMI site released to the Susquehanna River j
after processing, were made within the regulatory limits 'and in accordance with flRC requirements and City of Lancaster Agreement dated February 27, 1980.
The concentrations of radioactive material i
in the discharged effluent during this weekly period were less than the Lower Limits of Detection (LLD).

EPA Envir_o_nmental Data.
Results from EPA monitoring of the environment around the TMI site were as follows:
3 The EPA measured Krypton-85 (Kr-85) concentrations (pCi/m ) at several environmental monitoring stations and reported the following results:
Location December 12-December 19, 1980 3
(pCi/m )
Bainbridge 25 Goldsboro 20 Observation Center 27 fliddletown 16 All of the above levels of Kr-85 are considered to be back-ground levels.
fio radiation above normally occurrirg background levels were detected in any of the samples collected from EPA's air and gamma rate networks during the period from December 17 through December 31, 1980.

Results from !!RC monitoring of the environment around the if11 site were as follows:
The following are the i4RC ai" sample analytical results for the onsite continuous air som)ler:

Licensee Radioactive flaterial and Radwaste Shipments.
The following shipments were made:
On flonday, December 29,1980, two 40 ml Unit 2 reactor coolant samples were sent to Babcock and Hilcox (B&U), Lynchburg, Virginia.
On f4onday, December 29, 1980, 20 metal boxes of Unit I non-conpacted waste were shipped to the Chem-fluclear site, Barnwell, SoJth Carolina.
4 Major Activities 1.
Reactor Decay Heat Removal.
Decay heat removal continues to be removed by steaming (under vacuum condi tions) in the "A" Once Throuah Steam Generator (OTSG) and by heat transfer fron reactor coolant system to reactor building ambient.
The onsite staff has approved the licensee's proposal (procedure) to use the loss to ambient mode as a means of decay heat removal.
Implementation of the licensee's procedures is expected next week.
3 2.
_ Spent Resin Storage Status.
Sixty-six spent resin liners generated from EPICOR I and II are stored in "A" longterm waste storage nodule.
Six of the occupied cells contain stacked 4' x 4' liners (two per storage cell). The "B" longtern waste storage module is holding seven spent resin liners with a holding capacity equivalent to Module "A" (60 cells).
The licensee has continued to relocate liners from the temporary interim storage facility.
Only five of the twenty-eight spent resin storage cells hold liners.
The final transfers are scheduled for the month of January,1981
L t
iteetings Attended On Tuesday, December 30, 1980, L. Barrett attended the TMI Advisory Panel meeting at the William Penn fluseum in Harrisburg.
The topic of discussion was the disposition of processed radioactive liquids.
Presentations were given by Mr. R. Arnold, Chief Operating Executive, GPU, and Mr. G. Hovey, Director TMI-Unit 2, GPU.
The panel listened to GPU's plans to decouple the processing of contaminated water and the discharge of the processed water.
GPU stated that the processed water could be safely stored on site and no formal proposal for final disposition of processed water would be presented to the NRC before 1982. Panel members discussed the urgency of processing the containment sump wattr, relative environmental impacts of releasing tritium in airborne or liquid form, and the definition of accident related water.
Future Meetings On Thursday, January 22, 1981, L. Barrett will attend a public briefing in Harrisburg sponsored by the Department of Environmental Resources on the status of decontamination at Three Mile Island. Following the presentation, the Nuclear Regulatory Commission, the Environmental Protection Agency and Metropolitan Edison will be available to answer questions.
