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.

The Proliferation Resistance and Physical Protection (PR&PP) Working Group of the Generation IV International Forum conducted a high-level pathway analysis of a hypothetical sodium fast reactor and integral fuel processing facility (called collectively the Example Sodium Fast Reactor, or ESFR), as a test of the effectiveness of its analysis methodology. This paper presents the results of the analysis based on the breakout scenario. Four representative strategies were chosen for analysis: diversion of low-enriched uranium feed material, two different types of misuse of the reactor facility, and misuse of the fuel processing facility. A high-level pathways analysis was conducted for each strategy to determine relative ranking of the proliferation-time measure, specifically as it applies to the postbreakout period.
