. EVENT DESCRIPTION AND PROBABLE CONSEQUENCES h O 2 l On March 10, 1980, Boston Edison received an analyses report from the Yankee l

Atomic Electric Laboratory which indicated that reportable concentrations of Cr-51 l o 3 l IO TTl I (339 i 14 pCi/kg) and Co-60 (167

• 25 pCi/kg) existed in a mussel sample taken l-1 ITrT) l - from the Pilgrim Station Discharge Canal on January 10, 1980.

l

{

O e l

These concentrations are in excess of 10 times the Lower Limit of Detection at l

l"5T' l I the Control Station in Marshfield (LLD for Cr-51 was 31.pci/kg and' for Co-60 l

1 O Ie I I-was 4.7 pCi/kg).
