Résumé

We provide a detailed overview of an ongoing, multinational test program that is developing aerosol particle data for some spent fuel sabotage scenarios on spent fuel transport and storage casks. Data being measured are to quantify the aerosolized materials plus volatilized fission products produced from actual spent fuel and surrogate material test rods, resulting from an impact by a high energy density device, HEDD. The need for this information has been strongly supported, and this program is coordinated by program participants in the U.S. plus Germany, France, and the U.K., as part of the international Working Group for Sabotage Concerns of Transport and Storage Casks, WGSTSC. Sandia National Laboratories, SNL, has the lead test role for conducting this program; test program support is provided by both the U.S. Department of Energy and Nuclear Regulatory Commission. WGSTSC partners need this research to better understand potential radiological impacts from sabotage of nuclear material shipments and storage casks, and to support subsequent risk assessments, modeling, and preventative measures. We provide a summary of the overall, multi-phase test design and a description of all explosive containment and aerosol collection test components used. We focus on the recently initiated tests on “surrogate” spent fuel, unirradiated depleted uranium oxide, and forthcoming actual spent fuel tests. The depleted uranium oxide test rodlets were prepared by the Institut de Radioprotection et de Surete Nucleaire, in France. These surrogate test rodlets closely match the short test rodlets of actual spent fuel from the H.B. Robinson reactor (high burnup PWR fuel) and the Surry reactor (lower burnup PWR fuel), both in the U.S. The characterization of the spent fuels and fabrication into short, pressurized rodlets has been performed by Argonne National Laboratory, for testing at SNL. The ratio of the aerosol and respirable particles released from HEDD-impacted actual spent fuel to the aerosol particles produced from surrogate depleted uranium oxide, i.e., the spent fuel ratio, SFR, will be determined under closely matched test conditions. We shall briefly summarize similar results from completed, surrogate tests that used non-radioactive cerium oxide sintered ceramic pellets in test rods, documented separately.
