Description
Technical field
A kind of Li-Pb alloy for nuclear industry relates to a kind of first interpolation of fusion reactor or experimental loop or Li-Pb alloy of online interpolation of being used for.
Li-Pb alloy.
Background technology
Li-Pb alloy utilizes lithium to produce the isotropic substance tritium of hydrogen in fusion reactor under the bombardment of high-energy neutron, and the deuterium generation nuclear fusion reaction of extracting in tritium and the seawater produces huge energy; And the plumbous reflected neutron in the alloy and the energy that nucleosynthesis produces taken away by the circulation cooling.Therefore, Li-Pb alloy becomes the critical material that collection tritium multiplication agent, neutron multiplication agent and three kinds of functions of heat-eliminating medium are one in the nuclear fusion stack, in the nucleosynthesis field important application is arranged.
The preparation of Li-Pb alloy exists many difficulties, and as Li and Pb density difference big (＞20 times), melt easily produces the composition gravity segregation; Very active, the blast easily of metal Li chemical property, low, the easy scaling loss volatilization of fusing point; The accurate control difficulty of lithium content is bigger; For preventing that the impurity element in the Li-Pb alloy from producing the corrosion to structured material of radioactive nuke rubbish and impurity element in the nuclear fusion reaction transmuting, hope can reduce the content of impurity element as far as possible, improves the purity of alloy.
Chinese patent publication number CN101440446A relates to the Li-Pb alloy of a kind of lithium content 0.68 ± 0.01% (wt.), but the composition range of this alloy is too narrow, in the fusion-casting process of reality, be difficult to accurate control, need wideer Li-Pb alloy of exploitation composition range and preparation method thereof.
To the corrosion of structured material, can adopt the content that as far as possible reduces impurity in the Li-Pb alloy on the one hand when in nuclear reactor, moving, reduce corrosion structured material for reducing the Li-Pb alloy liquation; By reducing the content of lithium in the Li-Pb alloy, activity reduction, the hazard level of Li-Pb alloy are reduced on the other hand, reduce corrosion structured material.So the content of lithium is towards developing less than the plumbous direction of the hypoeutectic lithium of 0.68% (wt.), this helps the long-time running of reactor.
Li-Pb alloy produces and constantly consumes lithium in the tritium process, needs online interpolation Li-Pb alloy.For reducing temperature drop and the interpolation time in the interpolation process, wish that the plumbous online addition of lithium is few as far as possible, this just needs the higher Li-Pb alloy of lithium content, and therefore, the content of lithium is towards developing greater than the plumbous direction of the hypereutectic lithium of 0.68% (wt.), and this helps online interpolation.
