COMBINED SYSTEM USING EXHAUST HEAT IN NUCLEAR REACTOR PLANT

摘要

PROBLEM TO BE SOLVED: To provide a nuclear reactor combined system capable of obtaining high thermal efficiency by effectively collecting and using the exhaust heat of a nuclear reactor in which about 1/2-2/3 of the heat value of the nuclear reactor is abandoned in a conventional nuclear reactor plant. SOLUTION: This nuclear reactor plant is provided with a coolant circulating passage which returns a high pressure coolant compressed with two stages via a first stage side compressor, an inter-cooler and a two-stage compressor to a nuclear reactor coolant port side via a regeneration heat exchanger after performing a heat exchange of a nuclear reactor coolant after operating a gas turbine by using the regeneration heat exchanger and a precooler. The heat exchange passage of at least one cooler of the precooler and the inter-cooler is connected to a chemical freezer and a heat circuit of a mechanical heat pump, and thereby the heat capacity of the coolant can be collected on the freezer side. Especially, the heat exchange passage of the precooler is connected to a heat circuit of the chemical freezer and the heat exchange passage of the inter-cooler is connected to the heat circuit of the mechanical heat pump.
