High temperature fission chambers engineered for AMR/SMR safety and performance
As the global energy landscape shifts towards safer, smaller, and more flexible nuclear power, Small Modular Reactors (SMRs) and Gen. IV* technologies are at the forefront of innovation. These advanced designs pose new challenges in size, efficiency, and operating environment that traditional instrumentation and control solutions aren’t always designed to handle.

Measurements of mega-electron-volt charged-particle losses in the JET tokamak are reported. The technique is based on sample activation by nuclear reaction from mega-electron-volt particles. Samples are used as flux monitors for leaking fusion plasma particles in the mega-electron-volt energy range. Ultra-low-level gamma-ray measurements were performed at three underground facilities in order to significantly enhance detection levels. Two measured radionuclides (48V and 7Be) were identified as produced predominantly from charged-particle reactions. Quantitative data on charged-particle fluxes to the wall were obtained for the first time as well as angular distribution with respect to the magnetic field.
