During the fuel dissolution this radioactive krypton is released into the air. This krypton release can be detected and ...

WebAlthough both yield more neutrons per fission when split by fast rather than slow neutrons, this is incidental since the fission cross sections are much smaller at high neutron energies. While the conversion ratio (the ratio of new fissile nuclei to fissioned nuclei) in a normal reactor is around 0.6, that in a fast reactor may exceed 1.0. WebGraph of Fission Product Yields.
