More than half of material thefts reported to IAEA occurred during transport
The International Atomic Energy Agency has said that more than half of all thefts of nuclear and other radioactive material reported to the agency’s Incident and Trafficking Database (ITDB) since 1993 occurred during authorized transport, with the share rising to nearly 70 percent in the past decade. The ITDB covers incidents involving nuclear material, radioisotopes, and radioactively contaminated material.

With the growth of the private fusion industry and a shift in R&D programs toward the engineering aspects of fusion energy systems, the study of neutronics is likely to play an increasingly important role in the overall design of fusion systems. The geometric complexity, deep shielding type problems, and needs for multiphysics integration and uncertainty quantification in fusion systems pose significant methodological challenges to be addressed by the fusion neutronics community. This panel brings together experts from industry, academia, and government laboratories to discuss the current state of fusion neutronics modeling and where challenges lay ahead.
