A nuclear power reactor is the most intense man-controlled source of electron antineutrinos. An installation of a neutrino detector in close vicinity to a reactor core (approximately 10 m) enables the study of neutrino properties with a higher efficiency, for example an investigation of short-baseline neutrino oscillations and a verification of sterile neutrino hypothesis. A knowledge of the antineutrino flux enables us to determine the reactor power in real time. Measurement of the antineutrino energy spectrum gives the possibility to investigate the isotopic composition of the reactor fuel and to monitor illegal manipulation of 239Pu. The S3 detector was developed as a common effort between IEAP CTU in Prague and JINR (Dubna). The high segmentation of the detector enables identification of the antineutrino interaction which has a specific time, energy and spatial pattern. The software for the data acquisition and visualization is under development in IEAP CTU in Prague. Since the detector does not contain any flammable, toxic, caustic and dangerous materials, it is safe to be installed under the industrial power reactor. The S3 detector has applications in fundamental physics, an applied research as well as nuclear safety.
