NeutronKinetics#
Point Kinetics Model#
This module contains a model of the neutronic power with six groups of delayed neutrons (it could be easily changed to 8 groups if needed). Starting from the total reactivity (model input from the ReactivityFeedbacks module), this module calculates the time evolution of the fission power of the reactor. The total power take into account also the residual power (which is computed and provided by the DeecayHeat module).
The default values for \(Tlife\) (prompt neutron lifetime), \(Beta\) (delayed neutron fraction) and \(lambda\) (decay constant), valid for U235, are taken from S. Marguet, La physique des réacteurs nucléaire, Ed. Lavoisier, 2013.
The equations can also be derived from the same source, setting:
\(n(t)\) proportional to \(Pneut\)
\(C_i(t)\) proportional to \(Pdelay\)
