The power of a nuclear reactor, in the operating conditions, presents fluctuations due to various causes. This random behavior can be included in the study of noise. Among other sources of noise, analysis was made of the fluctuations due to the discontinuous emission of neutrons from an independent source; and to the multiplication of neutrons inside the reactcr. The method used made use of the analogies between the rules governing a nuclear reactor in operation and a number of radioelectrical systems, in particular the feed-back loops. The reactor can be characterized by its passing band and is described as a system submitted to a sequence of random pulses. In non-linear operating conditions, the effect of neutron noise is defined by means of a non-linear functional, this theory is thus related to previous works. This leads, in particular in the case of nuclear reactors, to some results given in the ease of radioelectrical loops. (auth)
