NUCLEAR POWER PLANT Russian patent published in 2005 - IPC

FIELD: nuclear power engineering; liquid-metal cooled reactor plants.

SUBSTANCE: proposed nuclear power plant has liquid-metal cooled reactor using liquid lead or its alloys as coolant and incorporating reactor core whose space under empty state holds steam generators, circulating means, shielding gas system, and gas mixture inlet device in the form of motor-rotated gas-delivery chamber immersed under coolant empty state in its circulating path that communicates by means of channels with shielding gas system and with circulating coolant space; top and bottom walls of gas delivery chamber function as carrying members of liquid-metal coolant circulators shaping flow toward channel for gas mixture outlet from gas delivery chamber. Such design provides for dispensing with cold traps and with hydrodynamic and mechanical filters.

EFFECT: effective cleaning of reactor unit surfaces, core and steam generator heat-transfer surfaces from deposits of coolant oxides.
