Professionals, Teachers, Students and Kids Trivia Quizzes to test your knowledge on the subject. Fast reactors generally have an excess of neutrons (due to low parasitic absorbtion), the neutrons given off by fission reactions can “breed” more fuel from otherwise non-fissionable isotopes or can be used for another purposes (e.g.transmutation of spent nuclear fuel). The non-fissile isotopes 238 U and 232 Th are converted to fissile isotopes of 239 Pu and 233 U, respectively, thus producing fresh fuel during reactor operation.
