Stochastic Nonlinear Dynamics of Nuclear Power Plants: Noise Effects on Nonlinear Stability
It is well known from previous work of Bell  and Williams  that in a linear reactor model, fluctuations become very important during start-up operation with weak sources. At this point, it is important to distinguish two different types of random process which are at the origin of neutron density fluctuations: firstly we have the inherent randomness of the emission and absortion events, and secondly we have the parametric noise sources, i.e. external noise due to fluctuations in the reactor parameters.
