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.

These lecture notes provide a short overview of classical and neoclassical transport in tokamaks. The classical theory is widely applicable in laboratory and space plasma physics if the mean free path is shorter than the macroscopic scale length. The neoclassical theory predicts important phenomena in tokamaks such as the bootstrap current, electric conductivity, transport in the scrape-off layer, and cross-field transport in regions where the turbulence is suppressed.
