Uranium Oxide - an overview | ScienceDirect …

Newly fabried uranium oxide fuel contains up to 3–5% 235 U and the rest is 238 U. Nuclear reactions in the reactor burn up part of the uranium and produce radionuclides. A total of 80% of 235 U consumed is burned by fission reactions and 20% by neutron capture to 236 U. 236 U is then burned by neutron capture to 237 Np, 25% of which is then converted to 238 Pu.
