DETAILS

During the period of January,1986 though May,1988, Vennont Yankee Nuclear

Power Corporation disposed of sewage waste containing licensed material in the

Town of Brattleboro's sewage waste treatment facility. Sewage from two onsite

sewage holding tanks were routinely transported by truck to the treatment facility

and disposed of there. The COB holding tank was emptied approximately twice

per week during periods of heavy contractor activity. The main septic tank was

emptied twice per year. During the period of June 8-10, 1988, a representative

of the State of Vennant, Department of Health, made radioanalytical mea:urements

of sludge sampled at the Brattleboro sewage waste treatment facility. Soee of

-

the radioar.tivity measured originated at the Vermont Yankee Nuclear Power Station.

The radio .uclides Cs-137, Cs-134, Co-60, Mn-54, and Zn-65 itere found in the

sludge ramples.

Several of these radionuclides are byproc'ucts of the operation

of the fermont Yankee Nuclear Power Station.

A co;;y of the report prepared by the State of Vermont representative is enclosed.

The report indicates the presence of licensed material in the Brattleboro sewage

treatment facility sludge samples and provides specific concentrations of Co-60

that were detected. This situation is considered unresolved pending receipt

of the licensee's complete evaluation of this problem.

(88-09-01)

The Vermont Yankee Nuclear Power Station management was informed in a telephone

conversation with Dr. Walter J. Pasciak of the Region I office on July 5,1988.
