C NRC TMI PROGRAM 0FFICE WEEKLY STATUS REPORT Week of August 24-29, 1980 Plant Status Core Cooling Mode:
Cyclic natural circulation in tia "A" reactor coolant
' system (RCS) loop via the "A" once through steam generator (OTSG), steaming to the main condenser, and RCS loop-A and 8 cyclic natural circulation to-reactor building ambient.
1 Available Core Cooling Modes: 0TSG "B" to the main condenser; icag-tenn cooling "B" (OTSG-B); decay heat removal.
RCS Pressure Control Mode: Standby Pressure Control (SPC) System.
Backup Pressure Control Mode: Makeup system in conjunction with letdown flow (Emergency use only due to suspected leaks in the seal injection system).

Environmental & Effluent Information 1.
Liquid effluents from TMI-l released to the Susquehanna River, after processing, were within the limits specified in Technical Specifications.
2.
No liquid effluents were discharged from TMI-2.

Bainbridge 30 Goldsboro 28 Observation Center 33 Middletown 27 Hill Island 26 All of the above levels of krypton-85 are considered to be background levels.
EPA environmental stations registered background levels for air particulate and water samples.
Gama scan results for all sampling locations were negative.

Radioactive Material and Radwaste Shipments were as follows:
On Monday, August 25,1980, a 40 ml Unit 2 reactor coolant sample was shipped to Babcock & Wilcox (B&W), Lynchburg, Virginia.
On Wednesday, August 27, 1980, smear samples and various samples of glass and metal from the Unit 2 containment entry on August 15, 1980, were shipped to Exxon Nuclear Laboratories, Idaho Falls, Idaho.
-On Thursday, August 28, 1980, one shipment of Unit I non-compacted waste was sent to Chem-Nuclear System, Incorporated, Barnwell, South Carolina.
Major Activities 1.
EPICOR II System The system is presently in an outage condition.
Startup of this system is expected to occur next week.

Reactor Building Status Purging of the reactor building was not accomplished this week due to the relatively low currie content.
3.
Mini Decay Heat (MDH) System Preoperational testing'of the MDH pumps started this week. System operational readiness date was not finalized.
Meetings Held 1.
- 8. Snyder and J. Collins conducted a news conference at 10:30 a.m.,
on Monday, August 25, 1980, in the NRC Middletown office to discuss and answer questions about the staff's draft Programmatic Environ-mental Impact Statement (PEIS) for the decontamination and defueling of TMI-2.
2.
On Thursday, August 28, 1980. J. Collins was interviewed by radio station WKBO, Harrisburg, cracerning the staff's PEIS.
The program will be aired on Sunday, ".agust 31,1980, at 8:30 a.m. as part of the station's public service program.
Future Meetings 1.
On Wednesday, September 3,1980, J. Collins and B. Snyder will brief local elected officials, citizens, and the press on the i
contents of the PEIS. The meeting is being hosted by the PA l'
Department of Environmental Resources and will be held at the Forum j
Building, Harrisburg, beginning at 9:00 a.m..
Representatives of i
EPA will also be in attendance at this meeting.
j 2.
On Friday, September 5,1980, J. Collins and EPA representatives will brief members of the Susquehanna River Basin on the contents of the PEIS.
