Comparison Of Results From Two Spent Fuel Sabotage Source Term Experiments

Abstract

Estimation of the radiological impact of a sabotage attack on a spent fuel cask requires values for the respirable spent fuel aerosol that might be produced by the attack. Two potential sources of relevant source term data are reviewed and shown to provide consistent information which leads to values of 6 × 10⁻⁵ to 8 × 10⁻⁴ g of respirable surrogate spent fuel aerosol released from the cask per gram of surrogate fuel matrix disrupted by a sabotage attack using a high energy density device (HEDD). Using a respirable spent fuel to respirable surrogate conversion factor of 3 enables estimation of the spent fuel respirable source term from the experiments reviewed.
