Description

technical field [0001] The invention belongs to the field of nuclear power generation, and relates to a power generation system combined with a nuclear power unit and an absorption heat pump and a working method thereof. Background technique [0002] The pressurized water reactor is the main type of reactor used in operating nuclear power plants in the world, and the total installed capacity accounts for more than (60)% of the sum of all types of reactors in all nuclear power plants. Among various types of power reactors, the pressurized water reactor has the advantages of compact structure, small volume, high power density, deep average burnup, radioactive fission products are not easy to escape, good power self-stabilizing and self-adjusting characteristics, relatively safe and reliable, etc. , has been widely used. The conventional island of the pressurized water reactor nuclear power plant generates (300) degree steam through the nuclear reactor, and generates power thr...

AI Technical Summary

Problems solved by technology

The conventional island of the pressurized water reactor nuclear power plant generates (300) degree steam through the nuclear reactor, and generates power through the thermal cycle. Due to the low main steam parameters of the pressurized water reactor nuclear power plant, the steam temperature is not high, which seriously restricts the improvement of the power generation efficiency of the nuclear power plant
