Ef fluent and Environmental (Radiolooical) Information l

1.

Licuid effluents from the TMI site released to the Susquehanna River after processing, were made within the regulatory limits and l

in accordance with NRC requirements and City of Lancaster Agreement dated February 27, 1980.

During the period March 20, 1981, to March 26, 1981, the effluents contained no detectable radioactivity at the discharge point although individual effluent sources which originated within Unit 2 contained minute amounts of radioactivity.

Calculations indicate that iess tnan one millionth (0.000001) of a curie of cesium-137 (CS-137) was discharged.

This represents less than 0.0000lf, of tne permissable total liquid activity as specified in Technical Specifications for operational commercial reactors.

Major Events 1.

Submerged Demineralizer System (SDS).

Region I specialists in instrumentation and preoperational testing performed preliminary inspections on the SDS this week.

These inspections are expected to continue for the next three weeks. The fuel pool, which -

contains the SDS is expected to be filled with water near,the end of April.

EPICOR-II Spent Resin Dis'posal.' On March 25, 1981, the NRC revised - g-7-

the Unit 2 License to provide alternatives to on-site processing

u prior to ultimate disposal of radidactive EPICOR-II resins. When the NRC approved the operation of EPICOR-II in October 1979, the NRC required that the spent resins be mixed with a binder material, e.g., cement, prior to shipment for off-site disposal. This special requirement was established because it was expected that the EPICOR-II resin radioactivity loadings would be much higher than nonnal reactor waters and that they would be disposed of by routine low-level waste land burial practices.

Since October 1979, much has been learned about the EPICOR-II resins. The actual radioactivity loadings of the spent EPICOR-II resin liners are grouped into either highly loaded resin prefilters or lower loaded polishing resin beds. The curie content of the lower loaded EPICOR-II polishing resins are within the normal range of reactor resin wastes.

Consequently, there is no need for the addition of a binder material provided that the resin liners are dewatered and meet all DOT and NRC transportation rules and also meet applicable state burial site criteria. This amendment allows prompt shipment of these lower loaded polishing resins off-site for disposal.

The higher loaded prefilters are the subject of on-going waste disposal characterization by DOE. This work will determine the method of ultimate off-site dispostion.

4 Meetings Held 1.

On Tuesday, March 24, 1981, Lake Barrett met with area mothers to discuss various issues related to nuclear power. The mothers' stated that the TMI accident.has caused severe mental stress and

'J *

~

that this stress will continue especially if TMI Unit 1 is restarted.'

2.

On Tuesday, March 24, 1981 Harold Denton and Lake Barrett aktended a meeting of the American Society of Zoological Park Managers in

..o Hershey, PA. Mr. Denton gave an invited after dinner talk anda.x a

4 responded to questions concerning nuclear power. -. -+n.. $

3.

On Friday, March 27, 1981, Congresiman Morris Udall a'nd' members of the Energy and Environment subcomittee made an inspection tour of - -

TMI Unit 1 and TMI Unit 2.

During their visit, the.subcomittee members met with representatives of General Public Utilities and the U.S. Nuclear Regulatory Comission to discuss various issues related to the cleanup process of TMI Unit 2 and the possible restart of TMI Unit 1.

Later in the day they met with representatives of the Coalition of Greater Harrisburg Labor Union, TMI Alert, Building Trades Ur ion, Friends and Family of TMI, TMI Public Resource Center a1d other groups to be briefed on their concerns regarding TMI anc then held a press conference for media representatives and the public.

4.

On Saturday, March 28, 1981, Lake Barrett participated on a cail-in radio show marking the second anniversary of the accident on CBS affili;ted WCAU in Philadelphia.

Future Meetings 1.

On Monday, March 30, 1981, the NRC's Citizens Advisory Panel will meet with Congressman Morris Udall and members of the Energy and Environment subcomittee to discuss various issues related to the cleanup program for TMI Unit 2.

2.

On Wednesday, April 1,1981, Lake Barrett will meet with members of the Susquehanna Valley Alliance to discuss the TMI Programatic Environmental Impact Statement.

Representatives of EPA's Independent Scientific Advisory Panel will also discuss their findings.
