STEAM-GENERATING PLANT OF DOUBLE-CIRCUIT NUCLEAR REACTOR WITH BLOWDOWN AND DRAINAGE SYSTEM Russian patent published in 2021 - IPC F22B37/52 F28G9/00 G21C15/14 

FIELD: physics.

SUBSTANCE: proposed steam-generating plant of double-circuit nuclear reactor with blowdown and drainage system is implemented in closed loop without classical blowers and is designed for maximum pressure of working medium in steam generators (SG). Pouring water of SG is combined into one line, cooled in regenerative heat exchanger, then in after-cooler of blowdown and drainage and discharged behind sealed shell. Outside the sealed envelope purging water of SG is supplied for purification into system of special water purification of purging water of SG, calculated for maximum pressure of working medium in SG. After purification the purging water is returned to the sealed shell and through the regenerative heat exchanger into the feed pipelines of each SG.

EFFECT: technical result is increased flow rate of SG blowing, which leads to accelerated normalization of water-chemical mode even with considerable deviations and, as a result, to longer service life of each SG and steam generating plant as a whole, as well as reduction of energy losses for return of purified purging water to the second circuit, with simultaneous independence of the system due to lack of communication with equipment of the computer room.
