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.

Five-layered W/Cu functionally graded materials with fine grain sizes of 0.2, 1, and 7 m were fabricated by resistance sintering under ultrahigh pressure. Microstructure analysis found that they have a good graded composition distribution and mechanical properties. After about 2000 s edge plasma exposure in the HT-7 superconducting tokamak, the results indicated that the fine-grained tungsten can enhance mechanical strength, and it is favorable to hold back crack propagation and growth; however, the effects on impurity deposition and compound formation were not obvious.
