“As the plume from Pilgrim travels inside the bay and along the Outer Cape, it would be diluted by as much as 100 times from initial concentrations at the point of release. But that may not be enough to avoid accumulation of contaminants, according to the study. “Although the plume will be significantly diluted, the passing of the plume in close proximity to the coast has the potential to lead to the accumulation of some radionuclides in the sediments, and the long flushing times of the southern/eastern Bay further enhances this concern,” wrote Rypina.”
