mMRC

mMRC, or modified Millon Reaction Chamber, is a type of nuclear reactor designed for research and development purposes. It is a small, low-power reactor that operates at atmospheric pressure, making it safer and more cost-effective than traditional high-pressure reactors. The mMRC was developed by the Argonne National Laboratory in the United States in the 1950s and has since been used in various research projects, including studies on nuclear fuel behavior, reactor safety, and the development of advanced reactor designs.

The mMRC is a pool-type reactor, meaning that the fuel and coolant are contained in a pool of water. This design allows for easy access to the fuel and makes it possible to conduct experiments with different fuel types and configurations. The reactor operates at a power level of approximately 100 kilowatts, which is low enough to prevent significant heating of the surrounding environment but high enough to generate a neutron flux suitable for research purposes.

One of the key features of the mMRC is its ability to simulate the conditions found in a full-scale nuclear reactor. This makes it an ideal tool for studying the behavior of nuclear fuel under various operating conditions, including those that might occur in an accident scenario. The reactor's low power level and atmospheric pressure operation also make it a safer option for conducting experiments that might otherwise be too risky in a high-pressure environment.

The mMRC has been used in a variety of research projects over the years, including studies on the behavior of nuclear fuel under irradiation, the development of new fuel designs, and the investigation of reactor safety issues. Its unique design and capabilities have made it a valuable tool for the nuclear research community, and it continues to be used today in support of ongoing research and development efforts.
