Query: Influence of entropy changes on reactor period   The period of a nuclear reactor is considered as the average value of the
first passage time. This approach makes it possible to find the effect of
entropy changes on the period of the reactor during this period. Differences in
the reactor periods with and without entropy changes are found, as well as
possible features of the behavior of the reactor period when entropy changes
are taken into account. The relation of entropy changes to the period of the
reactor provides opportunities for controlling the behavior of the reactor.
