Abstract:

The U.S. Army Engineers Waterways Experiment Station and U.S. Army Engineer Division, Huntsville, have developed general design criteria and specific design review criteria for the earth-mounded concrete bunker EMCB alternative method of low-level radioactive waste disposal. An EMCB is generally described as a reinforced concrete vault placed below grade, underneath a tumulus, surrounded by filter-blanket and drainage zones. The tumulus is covered over with a low permeability cover layer and top soil with vegetation. Eight major review criteria categories have been developed ranging from the loads imposed on the EMCB structure through material quality and durability considerations. Specific design review criteria have been developed in detail for each of the eight major categories.
