WebJul 4, 2024 · Light water reactors are thermal reactors and can convert 238 U into 239 Pu. Technically they are "converters" not "breeders" because they cannot produce more Pu nuclei than they burn up fissile fuel nuclei. A fast reactor can be a "breeder"; that is, it can produce more Pu that it burns fissile fuel. Hence the interest in fast breeder reactors. WebFast reactors have high breeding ratios and more neutrons going around The breeding ratio is a measure of how much new fissile fuel a reactor is capable of producing as it runs. It is the ratio of the number of fissile …
