BC Cribs and Trenches Geophysical Characterization Project: One Step Forward in Hanford's Cleanup Process

摘要

A geophysical characterization project was conducted at the BC Cribs and Trenches Area, located South of 200 East at the Hanford Site. The area consists of 26 wastes disposal trenches and cribs, which received approximately 30 million gallons of liquid waste from the uranium recovery process and the ferrocyanide processes associated with wastes generated by reprocessing nuclear fuel. Waste discharges to BC Cribs contributed perhaps the largest liquid fraction of contaminants to the ground in the 200 Areas. The site also includes possibly the largest inventory of Tc-99 ever disposed to the soil at Hanford with an estimated quantity of 400 Ci. Other waste constituents included high volumes of nitrate and U-238.
