Web19 mrt. 2024 · Any plutonium that does not fission stays in the spent fuel. Spent nuclear fuel from U.S. reactors contains about one percent plutonium by weight. The different isotopes have different "half-lives" – the time it takes for one-half of a radioactive substance to decay. Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years.
