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.

A general spatial kinetics model has been developed for boiling water reactor (BWR) stability analysis utilizing nodal analysis, a commonly used technique for analyzing power distributions in large power reactors. Kinetics parameters for use in the kinetics equations have been derived by utilizing self-consistent nodal data and power distribution. Spatial coupling effects on the stability margin have been analyzed for a typical BWR. Various influences on stability are investigated. Spatial kinetics is found to have substantial effects on the stability margins for density wave oscillations.
