Power relaxation
Serpent relaxes the power distribution calculated in the iterations using the stochastic approximation based method[1], where the power distribution at iteration is calculated by
where is the unrelaxed power distribution tallied on iteration , is the relaxed power distribution after the previous iteration, is the active neutron population simulated on iteration and is an underrelaxation factor that can be defined by the set relfactor option.
