Plant Sta_tus i

Core Cooling Mode:

Cyclic natural circulation in the "A" reactor coolant system (RCS) loop via the "A" once through steam generator (OTSG), ; teaming to the main condenser, and RCS loop-A and B cyclic natural circulation to reactor building ambient.

I j

Available Core Cooling Modes:

0TSG "B" to the main condenser; long-term cooling "B" (OTSG-B); decay heat removal.

Liquid effluents from TMI-l released to the Susquehanna River, d

after processing, were within the limits specified in Technical Specifications.

2.

No liquid effluents were discharged from TMI-2.

EPA Environmental Data. Results from EPA monitoring of the er.vironment j

around the TMl site were as follows:

l The EPA measured Krypton-85 (Kr-85) concentrations (pCi/m3) at several environmental monitoring stations and reported the following results:

l Location Octob_r 17 - 24, 1980 l

(pCi/m3)

Bainbridge 17 Goldsboro 20 Observation Center 22 1

Middletown Insufficient Sample All of the above levels of Kr-85 are considered to be back-ground levels.

No radiation above normally occurring background levels were detected in any of the samples collected from the EPA's air and gamma rate networks during the period from October 22 through October 30, 1980.

4.

NRC Environmental Data.

Results from NRC monitoring of the environment l

around the TMI site were as follows:

The following'are the NRC air sample analytical results for the onsite continuous air sampler:

<8.2 E-14 <8.2 E-14 Environmental TLD measureinents for the period August 26 through September 30, 1980, have be.!n completed.

Evaluation of the TLD results and the statistical flutuations indicate gama radiation to be within the. expected range of the natural

..,3 background levels.

5.

Licensee Radioactive Material and Radwaste Shipments. The following shipments were made:

~~

On Monday, October 27,1980, a 40 ml Unit 2 reactor coolant sample was sent to Babcock and Wilcox (P W Lyrchburg, Virginia.

On Wednesday, October 29, 1980, a box containing Unit 2 air filter papers was mailed to Teledyne Isotopes, Westwood, New Jersey.

On Wednesday, October 29,1980, a Unit 1 Waste Evaporator Condensate Storage Tank (WECST) "A" Start-up sample was mailed to Teledyne Isotopes, Westwood, New Jersey.

3 Major Activities _

1.

Mini _ Dec_ay___ Heat (MDH) System.

The MDH system remains in an operational status pending turnover to the operations group and issuance of technical specifications.

2.

Reactor Building Entry and Purge.

The next entry into the Unit 2 reactor building is scheduled for Ncvember 13, 1980.

A minor purge of Kr-85 is expected prior to the entry.

The tasks for the entry are being reviewed by the onsite NRC staff.

Specifics will be j

detailed in next week's report.

]

3.

Reactor Decay Heat Cooling.

Reactor Coolant System (RCS) temperature parameters continue to remain at approximate steady state values i

(see plant status section). On three occassions during the week incore thermocouple temperatures decreased approximately 5 F.

It appeared a small-amount of natural circulation flow occurred in the RCS.

j The Loss of Decay Heat to Ambient Test is expected to start early next week.

Initial temperature changes are anticipated to be extremely slow due to already established equilibrium between decay

)

heat input and loss to ambient output in the RCS.

~

The onsite NRC staff continues to review this area.

t 4.

Ground Water Monitoring P_rogram.

The ground water nonitoring program to detect radioactive water leakage from the reactor building sump to the ground water is continuing.

Following a pump test at minitoring Well No. 2 on August 23, 1980, the maximum tritium level was measured at 4,940 picocuries per liter after i

the test. This value is within noted concentration values during previous observations.

4 Meetiris Held 1.

On Tuesday, October 28, 1980, J. Collins attended a luncheon meeting of the Si 'elton Kiwanis to discuss the contents of the draf t Progranmatt. Environmental Impact Statement (PEIS) and status of cleanup operations at TMI-2.

One of the major concerns expressed by those who attended the meeting was the schedule for possible restart of TMI-1.

2.

On Wednesday, October 29, 1980, B. Snyder, J. Collins, P. Leech.

O. Lynch, C. Hickey, L. Chandler and T. Elsasser held a public meeting at Havre de Grace, Maryland to discuss the contents of the draft PEIS.

The major concern expressed by those who attended the meeting was the potential adverse environmental effect on the lower Susquehanna River and the Chesapeake Bay which might result from activities related to the cleanup of TMI-2.

There was universal opposition to the dumping of any processed radioactive waste water into the Susquehanna River.

Many people voiced the opinion that radioact've releases to the river, no matter how small, would have adverse ;ffects on the shell fish and fishing industries in the Chesapeake Bay.

3.

On Friday, October 31, 1980, J. Collins, T. Elsasser, W. Kirk, EPA, and T. Gerusky, DER, met with the Lebanon Valley Chamber of Commerce to discuss the con. tents of the draft PEIS.

Those who attended the meeting expressed serious concern about the possibility of a one year delay until TMI-l would be restarted.

It was the opinion of those at the meeting that a delay of this nature would have very serious adverse financial impact on central Pennsylvania.

Methods of petitioning the NRC Commissioners for relief from the current shut down order were discussed at some length.

It is most probable that as a result of this meeting the Commissioners will be contacted by area Chambers of Commerce on this issue.

Future Meetin_gs 1.

On Thursday, November 6,1930, J. Collins will address the Middletown m;?

Rotary on the status of the TMI-2 cleanup program and the contents

- +,

of the draf t PEIS.

2.

A public meeting has been scheduled for Monday, November 10, 1980, at the auditorium of the Forum Building, Harrisburg, to discuss the draft PEIS.

Participating in the meeting will be NRC Commissioner V. Gilinsky, B. Snyder, J. Collins, F. Congel, T. Elsasser, and M. Bills from EPA.
