Recently, the Moscow Institute of Engineering Physics of the Russian state nuclear energy research university has carried out a series of tests to monitor the operation of nuclear reactors by using the effect of neutrino coherent elastic scattering, which is expected to increase the accuracy of remote control of nuclear reactors by nearly 1000 times. The research was funded by the State Atomic Energy Corporation of Russia. < / P > < p > one of the ways to monitor the operation of nuclear reactors is to analyze neutrino radiation, which helps to prevent the theft of nuclear fuel that can be used to make illegal nuclear weapons. Normally, the analysis of neutrino radiation is carried out remotely to avoid interference with the operation of a suspected nuclear power plant. < / P > < p > neutrinos are a large number of experimental particles formed in nuclear reactions, which can easily pass through the protective layer of nuclear power plants. Therefore, in order to prevent the neutrino leakage from the nuclear reactor, a “lead wall” with sufficient thickness is needed. By analyzing neutrino radiation, researchers can grasp the isotopic composition produced by nuclear reaction and the phenomena occurring in the center of reactor active region. Alexander bolozdenia, director of the cross teaching and research section Laboratory of experimental nuclear physics at the Moscow Institute of Engineering Physics, said that the so-called weapon plutonium was formed during the operation of the nuclear reactor, and the neutrino radiation detector could help detect the material when recording the changes in the isotopic composition of the reactor active region. Russian researchers have developed a new biphasic emission detector by using the neutrino coherent elastic scattering effect, which improves the neutrino detection method and helps to improve the accuracy of nuclear reactor remote control by nearly 1000 times. According to Alexander bolozdenia, the data obtained from neutrino coherent elastic scattering have been analyzed and the theoretical model has been greatly revised. He said relatively light argon nuclei were used as neutrino targets in the experiment. The nature of argon is close to that of xenon used in the experimental detector, but its price is only a fraction of that of xenon. Alexander bolozdenia said their new detector technology, which helps make nuclear energy safe and transparent, has attracted the attention of the International Atomic Energy Agency. At the same time, the new technology can also be used to analyze the neutrino radiation of the sun or supernovae to understand the processes occurring inside them. The research team plans to carry out the first tests at the Kaliningrad nuclear power plant in Russia next year. Global Tech
