"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. " - Fast breeding reactor
