Magnitude of Fissile Element at the Order of a Neutron.

[nucerl]

Consider a fissile element whose magnitude is at the order of a neutron. In this situation, how can we derive the point kinetic equations?

Thanks everyone.

Please clarify what one means by "Magnitude of Fissile Element at the Order of a Neutron".

There are 'fissile' nuclides which readily fission upon absorption of a neutron, as opposed to 'fertile' nuclides which require interaction with high energy (MeV) neutrons in order to fission but otherwise absorb neutrons and subsequently decay, possibly into fissile species.
