Nuclear reactor auxiliary heat removal system

摘要

An auxiliary heat removal system to remove residual heat from gas-cooled nuclear reactors. The reactor coolant is expanded through a turbine, cooled in a heat exchanger,and compressed by a compressor before reentering the reactor coolant. The turbine powers both the compressor and the pump which pumps a second fluid through the heat exchanger to cool the reactor coolant. A pneumatic starter is utilized to start the turbine, thereby making the auxiliary heat removal system independent of external power sources.
