Earthmounded Concrete Bunkers

Earth-mounded concrete bunkers (EMCB), a combination of trenches and vaults, are being strongly considered by many of the new state disposal sites mandated by Congress. EMCB disposal technology involves isolating low-level radioactive waste in an engineered vault located above or below the natural grade of the site. A multilayer, engineered earthen cover is positioned over the vault to provide an additional barrier. Depending on the design, Class A, B, or C wastes can be stored in these structures.

Other disposal methods for LLRW have been proposed, but at this time shallow land burial is the only successful and cost effective commercial method (Gershey, Klein, Party & Wilkerson 1990).
