Abstract: The period of a nuclear reactor is usually represented as a deterministic quantity. In this article, the reactor period is described as a random variable. An approach based on the first passage time is used. In this case, the effect of the change in entropy on the value of the period of the reactor is determined. Relations are obtained that describe the effect of entropy on the period of the reactor. Expressions are obtained for the dispersion of the reactor period. This value cannot be found from a deterministic approach. Knowing the effect of total entropy change on the period of the reactor makes it possible to control the behaviour of the reactor.

Keywords: first-passage time; entropy changes; reactor period.
