Description

A kind of chemical stability evaluation method of fluor-apatite ceramic solidification body
Technical field
The invention belongs to high-level radwastes(Abbreviation high-level waste)Processing and disposition, be related to a kind of fluor-apatite The chemical stability evaluation method of ceramic solidification body.Suitable for deep geological disposal environment, secondary actinium series high-level waste firming body Chemical stability evaluation under the effect of " thermal field, water flow field, the field of force, chemical fields " various factors coupling.
Background technology
With the continuous increase of human society energy demand, the increasingly exhausted and greenhouse gas emission of conventional fossil fuel Control requirement steps up, the selection that the mankind will must face follow-up alternative energy source.Nuclear energy is as a kind of safe and clean, warp The energy of Ji is expected to substitute traditional fossil energy on a large scale, is the essential energy of human social.So And Devoting Major Efforts To Developing and utilization with nuclear energy, generated high level radwaste(Abbreviation high-level waste)It is also more and more, The type of high-level waste is more, and chemical composition is complicated, particularly containing it is toxic it is big, radioactivity is strong, long half time secondary Excitation Bands Plain [neptunium(Np), americium(Am), curium(Cm)] high-level waste, greatly long-term potential danger is constituted to ecological environment and human health Evil, safe disposal causes the highest attention of the today's society public, it has also become restrict nuclear industry sustainable development it is crucial because One of element.
At present, the Nuclear waste disposal technology that countries in the world generally use is as follows:Glass is carried out to high-level waste first to consolidate Glass solidified body or ceramic solidification body, are then fitted into dedicated waste tanks by change or ceramic solidification, and finally dedicated waste tanks are put into positioned at ground In lower 500-1000 meters of deep geological disposal library, realize that high-level waste is isolated with the long-term, safe of biosphere.High-level waste Usually no less than 10,000 years deep geological disposal library projected life, the firming body containing high-level waste is in initial centuries Storage period The β decays of generation can make deep geological disposal library temperature be increased to hundreds of degree, underground moisture or influence on groundwater and come from addition To the irradiation damage of firming body, the long-time stability of high-level waste firming body and safety will be chosen by sternness for internal various decays War.Under the conditions of deep geological disposal, high-level waste firming body can be by thermal field(Thermal field), water flow field (Hydrodynamic field), the field of force(Mechanical field), chemical fields(Chemical field)Etc. multifactor coupling The influence of cooperation, the stability particularly chemical stability of high-level waste firming body will be by baptism.Therefore, it studies High-level waste firming body is at " thermal field, water flow field, the field of force, chemical fields "(Referred to as " heat, water, power, chemistry ")Change under coupling Stability is learned, to evaluating long-time stability and safety of the high-level waste firming body in deep geological disposal environment with very heavy The meaning wanted.
Fluor-apatite is one of most stable of mineral on the earth, is to find that 2,000,000,000 can be stabilized in nature so far A kind of mineral in year have high geological stability, irradiation stability, mechanical stability, thermal stability and chemical stability, Time requirement of the actinium series high-level waste to curing medium material can be met well.Fluor-apatite has very strong solid solution Excitation Bands The ability of element, the actinium series nucleic of the natural usual association high concentration of fluor-apatite(Thorium, uranium, plutonium)And its radioactive fission product.Root According to the isomorph principle on mineralogy, secondary actinium series nucleic has quite similar ionic radius with the calcium ion in fluor-apatite And chemical property, fluor-apatite can be firmly secured at secondary actinium series nucleic as a part for crystal on its lattice-site position, The fluorine phosphorus ash ceramic solidification body of acquisition has excellent long-time stability and safety.Therefore, fluor-apatite be curing height put it is useless One of ideal ceramic solidification base material of object, the secondary Excitation Bands with very long half-lift being particularly suitable in safe cured high-level waste Plain [neptunium(Np), americium(Am), curium(Cm)].In the prior art, scientific research personnel both domestic and external is only to fluor-apatite ceramic solidification body The solid solution capacity of synthesis technology, actinium series nucleic in fluor-apatite ceramic solidification body etc. has carried out certain research.However, for mould Intend deep geological disposal environment(100-200 DEG C of temperature, pressure 0.101-1.554MPa, pH value 5-9), fluor-apatite ceramic solidification body Chemical stability under the effect of " heat, water, power, chemistry " various factors coupling, is not reported both at home and abroad;It makes pottery for fluor-apatite Chemical stability of the porcelain firming body in deep geological disposal environment still lacks experimental basis and suitable evaluation method at present.
Invention content
The purpose of the present invention is intended to overcome deficiency of the prior art, provides a kind of chemistry of fluor-apatite ceramic solidification body Method for estimating stability is especially to provide a kind of simulation depth geological disposal environment of high-level waste firming body, studies fluor-apatite The chemical stability of ceramic solidification body fluor-apatite ceramic solidification body under the effect of " heat, water, power, chemistry " various factors coupling, is commented The method of long-time stability and safety of the valency fluor-apatite ceramic solidification body in deep geological disposal environment.Due to consideration that examination The safety tested, the present invention use nontoxic, "dead" lanthanide series [samarium(Sm), europium(Eu), gadolinium(Gd)] respectively simulation have Malicious, hot, ionic radius and the most similar secondary actinium series nucleic [neptunium of chemical property(Np), americium(Am), curium(Cm)].
