Yes, TerraPower is a company that is researching and developing advanced nuclear reactor technology, including the use of breed-and-burn reactors. Breed-and-burn reactors are a type of fast reactor design that aims to breed fissile material, such as uranium-233 (U-233) or plutonium, within the reactor core through the process of neutron capture.
In a breed-and-burn reactor, fertile material, such as depleted uranium or thorium, is irradiated by fast neutrons, which convert it into fissile material. In the case of TerraPower’s design, U-233 can be bred from thorium by capturing neutrons, and U-233 can then undergo fission to generate energy.
The goal of breed-and-burn reactors is to maximize the utilization of nuclear fuel and minimize the production of long-lived nuclear waste. By efficiently breeding fissile material within the reactor core, breed-and-burn reactors have the potential to achieve high fuel efficiency and reduce the need for frequent refueling.
However, breed-and-burn reactor designs are still in the research and development stage, and commercial deployment of such reactors may be several years or decades away. Regulatory approval, safety assessments, and public acceptance are also important factors that will influence the future of breed-and-burn reactor technology.
