Description
Technical field
The present invention relates to liquid metal technical field of heating, and in particular to a kind of direct-type liquid metal sodium high power heating
System and heating means.
Background technique
Sodium-steam generator is the important pivot of sodium-cooled fast reactor secondary circuit and three circuits, the heat that it generates reactor
Amount heats main water supply and generates steam, so that pushing turbine does work.Steam generator still separates secondary circuit and three circuits simultaneously
Important barrier, the rupture of heat-transfer pipe will cause serious sodium-water reaction, cause serious safety accident, influence nuclear power station operation
Safety, stability.In the research of sodium-cooled fast reactor and the test of steam generator, found by a large amount of literature survey,
The relatively early several country's heats that surrogate response heap exports in the way of gas heating for developing fast reactor.Wherein, 5.5MW power
Japanese SGTF (the Steam of India SGTF (Steam Generator Test Facility) rack and 50MW power
Generator Test Facility) rack is all made of gas heating, U.S. SGTR (the Steam Generator of 2MW power
Test Rig) test-bed equally uses fired heater.Flame heating method is matched there are intrinsic boiler and processing problems,
The heating method makes boiler increase a large amount of uncertainties in operation and safety simultaneously, improves the layer of empirical risk assessment
It is secondary, increase the probability that major accident occurs.
