MATERIALS 



Through the good offices of Mr. Philip Stohr, NRC, we 

 received from the operators of the two reactors at Mill- 

 stone Point, Connecticut (Millstone Point No. 1 and No. 2) 

 and of the Maine Yankee reactor at Wiscasset, Maine, 

 samples that represented their periodic storage tank dis- 

 charges for parts of the years 1977 and 1978. These were 

 replicates of the discharge samples that the operators 

 collect routinely for assay of major radionuclides. 



In the case of the Millstone Point reactors, the samples 

 were adjusted to represent the monthly discharge experi- 

 ence. The series we received began with January 1977, 

 continued through the year (without samples for August or 

 September), and through the first four months of 1978. 



In the case of Maine Yankee, we received a separate sample 

 to represent each discharge event, the volume representa- 

 tion being adjusted for those of the various tanks dis- 

 charged. Discharges occurred as seldom as once or as 

 often as eleven times a month. The period represented by 

 samples we have so far analyzed extended from 20 June 

 1977 through 25 March 1978.
