Description
Technical field
The present invention relates to a kind of solid spallation target structure for Accelerator Driven Subcritical nuclear power system, belong to
Nuclear energy technology field.
Background technology
ADS is Accelerator Driven Subcritical clean nuclear power system (Accelerator Driven Sub-critical
System) abbreviation, it is that the high energy proton utilizing accelerator to accelerate is sent out with weight target nucleus (such as lead or tungsten etc.)
Raw spallation reaction, the spallation reaction that proton causes can produce tens neutrons, produces by spallation reaction
Neutron drives subcritical cladding systems as neutron source, make subcritical cladding systems maintain chain reaction so that
Obtain energy and utilize unnecessary neutron multiplication nuclear material and transmuting nuclear waste.
Spallation target is a vitals in ADS system, the high energy proton that accelerator produces and spallation target
, there is spallation reaction, neutron could be produced in material collision rift.Neutron drives sub-critical reactor as neutron source, makes
Maintenance chain reaction, and transmuting nuke rubbish.
For ADS system, it is subcritical that the circulation of high energy incoming particle is turned into driving by the function of target system exactly
Covering reaches critical neutron, for the basic demand of target can be attributed to following some: (1) compact conformation,
It is prone to combine with covering；(2) running power high, power level is between 10 to 100MW；(3) neutron
Yield efficiency is high；(4) reliable and cheap attended operation can be carried out；(5) safety and less harmful can be carried out
Operation；(6) less refuse is produced.
From meeting above demand, think that melted liquid lead and lead bismuth eutectic (LBE) are mesh now
Front preferably selection.For lead bismuth eutectic, its distinct issues are radioactive products, due to bismuth metal
The polonium element produced after activation is the radionuclide that a kind of chemical toxicity is the strongest, and polonium is volatile, so
Under accident conditions, polonium can at high temperature quickly evaporate from lead bismuth eutectic, causes serious putting
Penetrating property consequence.For lead, its amount producing polonium by nuclear reaction is few, but lead must operate at higher temperature
Under degree, target is selected to the selection needing more experimentation finally to determine optimum.
Spallation target be designed with various ways: Brookhaven National Laboratory of (1) U.S. proposes many and adds
The concept of speed device propagation target, the concept such as including sodium-cooled fast reactor target piece, fused salt target, air cooling target；(2) Ou Hezhong
Heart team Conceptual Design " energy amplifier " uses liquid lead target；(3) Belgium MYRRHA meter
Draw and use liquid windowless lead bismuth eutectic spallation target；(4) European Union XT-ADS plan is banged by the way of windowless
Hit liquid lead bismuth metal spallation target；(5) Italy TRIGA plan combines the TRIGA being in subcritical state
Reactor uses a solid tungsten target；(6) Italy TRASCO plan use adds lead extrusion bismuth eutectic spallation
Target.
