Application de la théorie des processus en chaine de Kolmogorov dans le cas de réacteurs à plusieurs zones couplées (réacteurs réflechis, réacteurs à deux zones multiplicatrices)

Kolmogoroff chain process theory can be used to establish the generating probability distribution function of the number of pulses recorded in a given sequence of disjoint time intervals. The theory is used to study a subcritical nuclear reactor system composed of M (here M equals 2 or 3) coupled point zones into which neutrons are injected at random from external sources and cause chain reactions. The Kolmogoroff equations are formulated for a reflected reactor (one active and one passive zone) and for a reactor with two multiplying zones and a passive intermediate zone.
