RESIDUAL HEAT REMOVAL SYSTEM OF NUCLEAR POWER PLANT

摘要

PROBLEM TO BE SOLVED: To provide a residual heat removal system of a nuclear power plant.SOLUTION: A residual heat removal system of a nuclear power plant includes: an air duct provided outside a contaminant vessel; a heat exchanger which is located inside the air duct; a first pipeline which transmits vapor to be generated by a vapor generator inside the contaminant vessel to the heat exchanger; and a second pipeline which transmits the number of condensation cooled or condensed by the heat exchanger to the vapor generator, and performs air cooling of the heat exchanger by using the external air which circulates inside the air duct.
