ABSTRACT:
A method of measuring reactivity of a nuclear reactor includes automatic normalization. Normalization is achieved by determining the ratio of a linear amplifier used to form an analog detection signal, before and after a range change has taken place. A normalization factor is calculated according to this ratio which is applied to a delay neutral precursor concentration used for calculating the reactivity period.
