Abstract

The invention discloses a fused salt reactor energy conversion system and an energy conversion method. According to the system, a fused salt reactor and a primary side channel of a first heat exchanger are connected in series to form a first fused salt loop, and the first fused salt loop is used for transmitting nuclear fission energy to a second fused salt loop and a third fused salt loop; a secondary side channel of a second heat exchanger and power generation equipment are connected in series to form a power generation working medium loop; a secondary side channel of the first heat exchanger and a primary side channel of the second heat exchanger are connected in series to form the second fused salt loop, and the second fused salt loop is used for transmitting energy of the second fusedsalt loop to the power generation working medium loop; the secondary side channel of the first heat exchanger and a primary side channel of an energy storage heat exchanger can be connected in seriesduring the low power peak to form the third fused salt loop, and the third fused salt loop is used for transmitting energy of the third fused salt loop to fused salt in a secondary side channel of the energy storage heat exchanger; and a cold fused salt storage tank is used for providing the fused salt for the secondary side fused salt channel of the energy storage heat exchanger during the low power peak. The system and the method can effectively solve the problem of power grid load fluctuation.

Description

technical field [0001] The invention relates to a molten salt reactor energy conversion system and an energy conversion method. Background technique [0002] At present, when the grid load fluctuates within 5%, it is an acceptable range for nuclear power plants. When the power grid load changes by more than 5%, nuclear power plants often reduce the operating power of the nuclear power plant to meet the demand of the grid load change. This method of reducing power to adjust the load makes the operation of the nuclear power plant extremely uneconomical. [0003] Molten salt reactor, as a candidate for the fourth-generation high-temperature nuclear reactor, has the advantages of economy, safety, sustainability, non-proliferation, inherent safety, and can use solid or liquid fuel. It has always been a research and development hotspot at home and abroad. Molten salt is a good heat transfer medium, large specific heat capacity and high boiling point, and can be used as a heat tra...
