/ Abstract
There has been designed an experimental project «Neutrino-4» for 100 MW reactor SM-3 to test the hypothesis of the «reactor antineutrino anomaly» [1, 2]. Advantages of the reactor SM-3 for such an experiment are low background conditions as well as small dimensions of a reactor core – 35x42x42 cm 3 . One has carried on the Monte-Carlo modeling of a position sensitive antineutrino detector consisting of 5 operation sections, which as a result of displacement, covers the distance from 6 to 13 meters from the reactor core. One has succeeded in obtaining an experimental area of sensitivity to oscillation parameters 2 m and 2 sin 2 , which enables to verify the hypothesis of reactor antineutrino oscillations into a sterile state.
