Abstract |
In March-April 1999 The U.S. Department of Energy (DOE), the U.S. Environmental Protection Agency (EPA), and the Washington State Department of Ecology (Ecology) signed the K Basins Interim Action Record of Decision (ROD). The ROD directed removal of the spent nuclear fuel (SNF), sludge, water, and debris from the two K Basins in Hanford's 100 K Area. The ROD also directed that the basins be decontaminated to the extent necessary to make it safe to drain the water from the basins which is used for shielding and contamination control from radioactivity in the basins. The amended remedy changes the sludge disposition and how underwater debris is retrieved, treated, and disposed from both the 105-K East and 105-K West Spent Nuclear Fuel (SNF) Basins. These changes will result in increased protection to human health and the environment. |
