- Аннотация: In 1979, there was a serious accident in the U.S. at the Three Mile Island nuclear power plant (NPP) which involved two NPP units. In 1986, the world witnessed a large-scale disaster in the USSR at the Chernobyl NPP that operated four NPP units. The last major accident occurred in March of 2011 in Japan, where six reactors were involved. It is known that during the nuclear reactions in the reactors the flows of anti-neutrino are released. At first, the neutrino (ν) emission was postulated as extremely high-penetrating, practically non-reactive to the matter. However, the capture cross sections (CCS) of ν, although really having very low values, are being measured at the extremely rough criteria. The situation here is somewhat similar to what happened to the neutron (n). n also has high penetrating capacity and often low CCS, but, nevertheless, the cases of resonant interaction processes of n, which have CCS of many orders larger than usual, were well known. Since the discovery of the ν, the "pervasive bias" has been adopted in its properties description, and little is known about its possible resonant interactions with matter. Resonant interactions are widespread in the microcosm and the elementary particles physics, and it is not prudent to exclude their presence for ν, even with a very small probability. It must be said that for the relict ν, the high level of interaction with matter is already discussed, but with the proviso that it is not typical for nuclear ν. It is obvious for the major part of the ν energy spectrum, but not for resonant. There is also another point: the interaction of ν with matter is among the weak interactions, but the interaction between the particles themselves can proceed according to strong interaction mechanism [1-3]. This radically changes the situation: the presence of two or more ν fields close to each other can lead to a strong interaction between them, precisely: 1) To a sharp acceleration of the inverse β-process which will lead to a large release of additional energy. 2) To an increase in the fraction of excited nuclei in fissile material, which will lead to a decrease in its critical mass, and to an uncontrolled change of the reactor regime to a supercritical state. Therefore, the work of two or more reactors located near each other is extremely dangerous. However, the tendency to a greater increase in the number of cooperating NPP units (up to 7-8) is clearly observed. The conception of independence of the adjacent units, which is the prevailing conception at present, may appear misleading. At present, the most dangerous situations exist in Japan, Canada, India, Ukraine and Russia. In addition to the mutual influence of NPP units, the question of the effect of natural neutrino flow on their work also requires a systematic study.
