In order to safely remove transuranic waste (TRU) and mixed low-level waste buried in the subsurface disposal areas (SDAs), it is important to anticipate exactly what materials are directly below the surface.  This project will develop neutron-based, logging tools that can identify TRU and volatile organic compounds (VOCs) in the vicinity of probe holes, thereby permitting safer retrieval and removal of waste from the SDA.  Phase I demonstrated that the tools can identify the material, quantify its concentration, and estimate the radial distance to objects.  Phase II will:  (1) modify to the tools to peform reliably, (2) characterize the response of the tools to TRU and VOC materials, (3) develop data interpretation methods based on the characterization data, and (4) demonstrate the value to personnel concerned with waste removal at the SDA.

Commercial Applications and Other Benefits as described by the awardee:  The technology should lead to the development of a commercial logging service for SDAs that will be made available to the Department of Energy.   In addition, these tools, in modified form, should be directly appicable to the metal mining industry as a complement to core drilling.
