Leaking Sr-90 will increase Vermont Yankee's eventual decommissioning costs

Entergy Nuclear has now admitted that the bone-seeking radioisotope Strontium-90 has been discovered in soil near underground leaking pipes at its Vermont Yankee atomic reactor on the bank of the Connecticut River. Several years ago, Sr-90 was also detected leaking from the high-level radioactive waste storage pool at Entergy Nuclear's Indian Point atomic reactors on the bank of the Hudson River in New York State. Nuclear engineer Arnie Gundersen of Fairewinds Associates warns that Sr-90, which is highly soluble in water, can concentrate in bones and cause leukemia, and thus is the most hazardous radioisotope yet discovered leaking into the environment at the 38 year old reactor just across the Connecticut River from New Hampshire, and just several miles upstream from Massachusetts. Gundersen points out that this latest discovery means eventual decommissioning costs will climb yet higher at Vermont Yankee. Entergy Nuclear has contributed nothing to Vermont Yankee's inadequate decommissioning fund since taking over ownership and operations in 2002. Other leaking elements discovered into the site's groundwater and soil include tritium, cobalt-60, cesium-137, manganese-54 and zinc-65. Raymond Shadis of the New England Coalition on Nuclear Pollution is very skeptical that Entergy Nuclear's assurances that all Sr-90 contamination at Vermont Yankee has now been accounted for and cleaned up.
