The nuclear cross section of a nucleus is used to describe the probability that a nuclear reaction will occur. The concept of a nuclear cross section can be quantified physically in terms of "characteristic area" where a larger area means a larger probability of interaction. The standard unit for measuring a nuclear cross section (denoted as σ) is the barn, which is equal to 10 m , 10 cm or 100 fm . Cross sections can be measured for all possible interaction processes together, i… WebFission product release in thoria and urania defective fuel experiments FDO-680 and FDO-681 ...

WebHigher fission cross-section of 239 Pu. The fission cross-section is about 750 barns in comparison with 585 barns for 235 U. Higher energy release per one fission event. A MOX core does not require the neutron flux of the uranium fueled core to generate the same energy. Larger fissile loading. The main reason is the larger fissile loading.
