- Аннотация: In 1979, there was a serious accident in the U.S. at the Three Mile Island nuclear power plant(NPP) which involved twoNPP units. In 1986,the world witnessed a large-scale disaster in the USSR at the Chernobyl NPP that operated fourNPP units. The last major accident occurred inMarch of 2011 in Japan, where six reactorswere involved. It is known that during thenuclear reactions in the reactors the flows of anti-neutrino are released.At first, the neutrino () emission waspostulated as extremely high-penetrating, practically non-reactive to thematter. However, the capture cross sections (CCS) of , 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 (n0). n0 also has high penetrating capacity and often low CCS, but, nevertheless,the cases of resonant interaction processes of n0, which have CCSof many orders larger than usual, were well known. Since the discoveryof the , the "pervasive bias" has been adopted in its propertiesdescription, and little is knownaboutits possible resonant interactions with matter. Resonant interactions are widespread in the microcosm and the elementary particlesphysics, and it is not prudent to exclude their presence for , even with a very small probability.It must be said that for the relict , the high level of interaction with matter is already widely discussed, but with the proviso that it is not typical for nuclear . It is obviousfor themajor part of the energy spectrum, but not for resonant. There is also another point: the interaction of with matter is among the weak interactions, butthe interaction between the particles themselves can proceed according to strong interactionmechanism[1-3].This radically changes the situation: the presence of two or more 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 ofthe reactorregimeto 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 ofthe effect of natural neutrinoflow on their work also requires a systematic study.
