. EVENT DESCRIPTION AND PROBABLE CONSEQUENCES h O 2 l On March 10, 1980, Boston Edison received an analyses report from the Yankee l o 3 l Atomic Electric Laboratory which indicated that reportable concentrations of Cr-51 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) . l 80 7 8 9 E CO E $ 8CO E COMPONENT CODE SU8 ode SU E 7
