Abstract
The paper presents a criticality analysis of the first fatal nuclear accident with unexpected criticality of the fissionable system. The operator of the experiment, Harry Daghlian, received a radiation dose of about 5.1 Sv and died 28 days later due to acute radiation syndrome. The paper features a numerical reconstruction of the experimental set-up and the environment in the laboratory at the time of the accident, based on publicly available documentation. The Monte Carlo Continuous Energy Burnup Code was used in all criticality calculations. The study is a follow-up of the previous criticality analysis of the Louis Slotin accident (LA-2), in which the same plutonium core was used in a fatal experiment. In the paper, I present the numerical model developed, the influence of the system components on the criticality state, the approach to criticality in function of the tungsten-carbide reflector mass, as well as a benchmarking study using JEFF3.1 and ENDF/B-VII.1 nuclear data libraries.
