Description

Technical field [0001] The invention belongs to the field of comprehensive utilization of energy, and specifically relates to a system for providing condensed water (steam) heat to a low-temperature multi-effect distillation seawater desalination device after power generation by a high-temperature gas-cooled reactor. Background technique [0002] The high-temperature gas-cooled reactor uses helium as the coolant and graphite as the moderator and structural material. Many tiny "coated particles" of nuclear fuel are dispersed in the graphite to form fuel elements. The helium temperature at the exit of the core can reach 700-950℃. The Shidaowan High-Temperature Gas-Cooled Reactor Nuclear Power Station is China’s first high-temperature gas-cooled reactor demonstration power station with independent intellectual property rights, and the world’s first modular high-temperature gas-cooled reactor demonstration power station with the safety features of the fourth-generation nuclear energy...
