LASER SYSTEM FOR MEASURING HEAT CARRIER PARAMETERS OF NUCLEAR POWER REACTOR Russian patent published in 2019 - IPC G21C17/22 G01N21/27 

FIELD: nuclear energy.

SUBSTANCE: invention relates to nuclear power engineering and is intended for rapid measurement of heat carrier parameters of water-water power nuclear reactor. Laser system for measuring heat carrier parameters of nuclear power reactor. Proposed plant comprises first and second laser generators, measuring cell connected to heat carrier circuit, first reference cell, three photoreceiving units, controlled spectral filter, two optical switches, information processing and control unit, as well as four reflecting mirrors and six semitransparent mirrors. Apparatus enables to perform high-accuracy determination of heat carrier parameters in a first or separately in a second circuit of a nuclear reactor based on radiating heat carrier by laser probing radiation and measuring parameters of Raman scattering of laser radiation caused by molecules of boric acid and molecules of impurity substances.

EFFECT: invention increases sensitivity of the laser measuring system and increases accuracy of determining concentration of boric acid and impurities formed during operation of the nuclear reactor.
