Playing the “bad guy” to enhance next-generation safety
Sometimes, cops and robbers is more than just a kid’s game. At the Department of Energy’s national laboratories, researchers are channeling their inner saboteurs to discover vulnerabilities in next-generation nuclear reactors, making sure that they’re as safe as possible before they’re even constructed.

A mock-up of the inboard shield and vacuum vessel of ITER was set up at ENEA Frascati and irradiated with 14-MeV neutrons produced by the Frascati Neutron Generator. The mock-up includes the coil region, and its dimensions and materials composition are consistent with the latest ITER design. The objective of the experiment is to validate the calculations of nuclear heating in the ITER toroidal field coil performed with the Monte Carlo code MCNP-5 and the FENDL-2.1 library, through measurement performed by thermoluminescent dosimeters. The goal was to reach a calculated-to-experiment accuracy of less than or equal to ±10%, possibly as low as ±8%.
