Description
Technical field
The invention belongs to active nucleus waste matter process and dispose, relate to a kind of sodium zirconium phosphate-monazite glass
Ceramic solidification body and preparation method thereof.Be particularly well-suited to that the fields such as nuclear industry are discharged containing plutonium, transuranium unit
The cured of the high-level waste (i.e. high-level waste) of element.
Background technology
China and people of the world's living standard raising and scientific and technological progress are created by the peaceful use of nuclear energy
Far-reaching influence, becomes the part that mankind's pace of progress can not lack suddenly.But the development of core cause is inevitable
Producing a large amount of radwaste, especially high-level waste, these radionuclides once enter biosphere,
By the radioactive pollution to bringing on a disaster property of the people of the world, it is necessary to this is properly settled.Along with
Contradiction between the increase of nuclear waste generation amount and core cause fast development needs, how to it
Safely and effectively process and dispose so that it is become current domestic outer core with biosphere isolation to greatest extent
One of key issue that career development is urgently to be resolved hurrily.
In prior art, processing method economically viable to high-level waste is the solidification selecting stability the highest
Base material, " confines radionuclide ", then carries out deep geologic disposal so that it is to greatest extent with
Biosphere completely cuts off.Wherein, cured is the step directly directly contacted with high-level waste Radionuclide, also
It is critical that a step.The curing process of low-level waste and technology comparative maturity, and obtain
The application of through engineering approaches.High-level waste cured mainly has prosthetic graft solidification and glass solidification two kinds.People
Though chemical stability, heat stability and the Flouride-resistani acid phesphatase of lithogenesis stone cured firming body are all preferable, but its
Curing process is complicated, poor, to element in high-level waste with the compatibility containing refuses such as high concentration sodium salts
Selectivity is the strongest, it is impossible to the whole components in disposal solidifying high-level waste.It addition, prosthetic graft is solid
The equipment that change uses in processing is complicated, and cost is high, and in processing procedure, the consumption of material and the energy is the biggest.
Therefore the preferred manner that current countries in the world carry out cured to high-level waste is glass solidification.Glass is solid
Change processes mainly pyrex and phosphate glass solidification two class.Borosilicate glass is because of in refuse
" objectionable impurities " (such as: phosphate, molybdate, sulfate, ferrum oxide and some other heavy metal oxygen
Compound) dissolubility excessively poor, cause prepared firming body that " yellow phase " easily occur and performance does not reaches
Requirement.Have to improve glass melting temperature for meeting performance requirement, or drop for cost to reduce containing amount
This type of " impurity " content in firming body low.This at aspects such as raising volume reduction ratio and reduction costs is all
Worthless.And ferrum phosphate system glass effectively solves the problems referred to above.But ferrum phosphate system glass
The irradiation stability of firming body is poor relative to borosilicate glass firming body with heat stability so that it is reality should
With being restricted.Additionally, according to practical experience, either borosilicic acid system or phosphate system glass
Firming body, the containing amount of its high-level waste is the most relatively low, and is easy in practical operation in solidification
Body glass is formed uncontrollable crystallite phase or produces uncontrollable split-phase and make the stability of gained firming body
Drastically reduce.
Summary of the invention
The purpose of the present invention is intended to overcome deficiency of the prior art, utilizes glass ceramic material as solidification
Base material has that pure amorphous glass material waste containing amount is big concurrently, contain that refuse kind is many, composition adjustability big and
The advantage of pure crystalline ceramic material energy " confinement " long lived nuclides steady in a long-term, it is provided that a kind of simple effective,
With sodium zirconium phosphate-monazite glass ceramics as base material, can be with the phosphoric acid of components whole in cured high-level waste
Zirconium sodium-monazite glass ceramics firming body and preparation method thereof, thus provide for high-level waste cured
A kind of new effective firming body and active nucleus waste matter process and method of disposal.
