ИСТИНА

JUNO-TAO is a liquid scintillator antineutrino spectrometer being built as a satellite experiment within the Jiangmen Underground Neutrino Observatory (JUNO). The JUNO-TAO detector will be placed about 30 m from one of the twins EPR reactors of the Taishan nuclear power plant (Taishan, Guangdong Province, China). In the 90s of the XX century, it was experimentally proved that antineutrino spectrometers based on liquid scintillators are capable of monitoring the power of a nuclear reactor and the isotopic composition of fuel in real time. These capabilities provide a complementary way of nuclear power plant reactor monitoring with respect to the standard methods. Moreover, such capability offers a promising safeguard tool for independent verification of the declared reactor power. The development of such monitoring tool supported by the International Atomic Energy Agency (IAEA). Ten square meters of cooled SiPM photons sensors with more than 50% photon detection efficiency will observe the spherical volume of liquid scintillator with 4500 photoelectrons per MeV light output in the TAO detector. The detector will fix about 2000 reactor antineutrinos per day. It is designed to be well shielded from cosmogenic and ambient backgrounds to have a 10% background-to-signal ratio Unique spectrometry capabilities due to symmetrical construction, low temperature scintillator and cooled photo sensors together with comprehensive active and passive shielding make TAO-detector an ideal tool to contribute greatly to this effort and open a possibility for industrial tool development
