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.

Volatilization of I34Cs from simulated high-level waste glass in a canister during several reheatings up to a maximum of 1000°C was examined. The results showed that the temperature dependence of the amount of 134Cs suspended in the air inside the canister could be divided into two categories. As the temperature was increased above 500°C, the amount of 134Cs suspended in the air inside the canister also increased. On the other hand, for temperatures <500°C, the amount of 134Cs suspended in the air inside the canister had an almost constant value after several reheatings up to a maximum of 1000°C. In this case, the air contamination by cesium-bearing material inside the canister is considered to be significant even at waste storage temperatures <500°C.
