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.

In this research, the effect of the shape of hydrogen-loaded palladium elements on exothermic reactions between gases is shown. It was found that an element with parts of its surface next to each other spontaneously triggers reactions, whereas an element whose surfaces are not next to each other needs outside triggering. The heat developed makes the temperature of the elements rise even by a few hundredths of a degree centigrade.Through photographic techniques, it was shown that the elements, when releasing heat, emit radiation connected to nuclear fusion reactions. These reactions, confirmed also by the analysis of the used hydrogen, showed helium formation. All these tests have confirmed the reproducibility of the phenomenon.
