CLEANER REACTORS. In a reactor with thorium fuel, some neutrons are absorbed by thorium-232 atoms, which become uranium-233. Uranium-233 is a more efficient nuclear fuel than uranium-235 or plutonium, with a high fission cross-section, a high number of neutrons released per fission (which makes it easier to sustain a critical reaction), and a …Web

interest in thorium as a nuclear fuel continues in part owing to its higher abundance relative to uranium.
