Deep horizontal drillhole disposal is the concept of disposing of high-level radioactive waste from a nuclear reactor in deep horizontal boreholes instead of in more traditional deep geological repositories that are excavated like mines. The design concept is intended to improve upon the vertical borehole concept developed by Sandia National Laboratories, by utilizing modern advancements in directional drilling technology as well as using isotopic methods to measure the affinity a host rock has for isolation.
