Abstract

The US DOE Office of Nuclear Energy Used Nuclear Fuel Disposition Campaign (UFDC) is initiating a Deep Borehole Field Test (DBFT), which will not use any radioactive waste, to evaluate the geoscience bases and technical feasibility for implementation of deep borehole disposal (DBD). DOE has identified Sandia National Laboratories (SNL) as the Technical Lead for the UFDC DBFT Project for supporting DOE in (i) developing the overall DBFT Project Plan, (ii) managing/integrating of all DBFT Project activities, and (iii) providing technical guidance to DOE, other DOE National Laboratories, and university partners. The DBFT includes drilling one Characterization Borehole (CB-8.5” diameter), followed by an optional Field Test Borehole (FTB), to a depth of about 5,000 m (16,400 feet) into crystalline basement rock in a geologically stable continental location. The DBFT CB will be drilled and completed to facilitate downhole scientific testing and analyses. If site conditions are found to be favorable, DOE may drill the larger-diameter (17”) FTB to facilitate proof-of-concept of handling, emplacement, and retrieval activities using surrogate waste containers. Discussion will cover guidelines for favorable DBFT site geohydrochemicalmechanical characteristics, example data sets for sites, and status of the DBFT Project.

Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the United States Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000. SAND2015- 6664A.
