Are limit cycle calculations a stochastic process

PDF Version Also Available for Download.

Description

Stochasticity is typically associated with processes that produce uncertain results which, in many cases, are due to process nonlinearities and/or extreme sensitivity to initial conditions. By its name, a stochastic process should have a probabilistic or random nature; however, it is well known that many if not all, of the processes that behave stochasticly are indeed deterministic. This is the case with computer calculations to predict the stability of boiling water reactors (BWRs). This paper attempts to introduce the reader to some of the stochastic'' uncertainties involved in this topic, and in particular the errors introduced by the approximations used ... continued below

Description

Stochasticity is typically associated with processes that produce uncertain results which, in many cases, are due to process nonlinearities and/or extreme sensitivity to initial conditions. By its name, a stochastic process should have a probabilistic or random nature; however, it is well known that many if not all, of the processes that behave stochasticly are indeed deterministic. This is the case with computer calculations to predict the stability of boiling water reactors (BWRs). This paper attempts to introduce the reader to some of the stochastic'' uncertainties involved in this topic, and in particular the errors introduced by the approximations used to integrate numerically the solutions in the time domain. The knowledge of this type of errors is relevant not only in BWR stability calculations but also in time domain calculations involving nonlinear or stochastic processes.
