The temperature controlled passive shutdown unit SASS of magnetic material Curie point and gas expansion driven device are set simultaneously in reactor core
GEM), Japan and the U.S. have carried out more research to this device；(3) the passive shutdown unit of liquid suspension is normal to transport
Under row operating condition, control rod is set to be located at reactor core top using coolant buoyancy, under accident conditions, coolant flow drops to design limit
When value, control rod weight is more than coolant buoyancy, and control rod falls, and what this shutdown unit was directed to is also non-protected defluidization thing
Therefore.The representative of this shutdown unit is the passive shutdown unit PPS and HRS of liquid suspension of Russia；(4) control rod thermally expands
Strengthen driving mechanism, control rod drive mechanism is used using thermal expansion strengthening design, the critical material of driving mechanism with special
The material (for example, thermal expansion coefficient is much larger than general material, or with temperature memory performance etc.) of fuel factor, when reactor temperature
When raising, fuel factor material property changes, and control rod then can be with a degree of underthrust；When temperature reaches setting limit value
When, the performance change of fuel factor material also reaches setting limit value, starts control rod release device, and control rod is inserted into heap by gravity
Core, Russian various temperature effect drive passive shutdown component, and Japanese reinforcing thermally expands driving device, and Germany is Europe
