Description In this paper, simple linear single-input-single output models of the reactor-regulating system have been considered, and risk-sensitive filtering and risk-sensitive parameter-estimation techniques have been used to obtain temporal-redundancy relations. While a risk-sensitive filter is used to provide a temporally redundant measurement of reactivity from an analytically redundant process parameter during a reactor start-up, a risk-sensitive parameter estimation technique is used to obtain temporally redundant measurements during steady state operation.
