Definitions
- the present invention relates to improvements in the process for vitrifying waste materials, and more particularly, to improvements especially for the vitrification of radioactive waste materials by changing the chemical form and physical characteristics of additives that are added to the waste material to obtain a suitable vitrified product, such that the reactions between the additives and the waste materials suppress the formation of undesirable secondary phases.
- waste vitrification the waste materials are mixed with appropriate amounts of raw materials, know as "additives”, and melted at a high temperature (typically 1150 0 C for JHCMs, typically somewhat lower for IMs, and typically somewhat higher for CCMs) in order to produce glass products that meet pre- specified product quality requirements.
- a high temperature typically 1150 0 C for JHCMs, typically somewhat lower for IMs, and typically somewhat higher for CCMs
- the product quality requirements mostly relate to the chemical durability of the glass product as measured by standard test procedures.
- the additives have been used either in the form of pre-melted chemicals (frit) with a specified composition, or raw materials in the form of minerals or chemicals.
- the additive minerals or chemicals are commonly referred to as glass forming chemicals (GFCs).
- GFCs glass forming chemicals
- the waste materials with the additives are designed to melt and form a glass product with a predetermined oxide composition.
- the waste materials mixed with the appropriate amounts of frit or GFCs are referred to as melter feeds. These materials may be mixed either outside or inside the melter.
- the melter feed is introduced from the top of the melter to the melt pool surface so that a layer of feed material covers the hot glass melt underneath.
- This layer is commonly referred to as the cold-cap.
- the cold-cap extends from partially melted melter feed in contact with the melt pool to unreacted melter feed at the top.
- the melt zone progresses from the hot wall on the outside into the bulk. Consequently, in this case also there is a boundary zone between predominantly melted material and predominantly unmelted feed material. This zone is also referred to as a cold cap. Reactions in the cold-cap, and controlling these reactions, are the key approach to mitigating undesirable secondary phase formation.
- Alkali molybdate phases can accumulate on the melt surface causing excessive corrosion of melter components that are in contact with this phase. Alkaline earth molybdates tend to sink to the bottom of the melter and accumulate. The accumulation of molybdate secondary phases at the melter bottom can cause problems with glass discharge, especially for melters that use a bottom discharge.
- the molybdate phase formation is a result of the high molybdenum concentration in the HLW feed to the vitrification facility in combination with complex reaction kinetics in the cold-cap. The molybdenum secondary phase formation initially occurs near the interface between the molten glass pool and the cold-cap. Our studies showed that kinetically controlled cold-cap conversion processes are responsible for the generation of molten molybdate salt, rather than solubility limits of molybdates in the underlying glass melt.
- the melter feed is prepared by mixing glass frit with the HLW material in slurry form, or when HLW is fed continuously and glass frit is fed periodically in small batches to the center of the cold-cap, the molybdate secondary phase tends to form before the underlying glass melt reaches saturation with respect to molybdate. If the feed chemistry can be altered to suppress the molybdate secondary phase formation until its concentration reaches close to the solubility limit, the amount of waste incorporated into unit amount of glass produced (waste loading) can be increased leading to substantial cost savings in HLW treatment and disposal.
- Sulfur is another component in waste streams that at high concentrations causes the formation of secondary sulfate layers during the melting process.
- the sulfate concentration in the glass that causes secondary phase formation can be as low as 0.5 wt% in certain glass compositions.
- the secondary sulfate layer is formed well before the underlying glass melt reaches sulfate solubility limit.
- improvements to the feed chemistry by judicious choice of additives to delay the formation of sulfate secondary phases until the sulfate concentration reaches close to the solubility limit, has enormous economical advantage.
- the same principles should be effective for mitigating other troublesome salt-forming species such as chlorine, fluorine, chromium (chromate), and phosphorous.
- the above objectives are accomplished according to the present invention by providing a method for vitrification of high level waste to reduce the formation of persistent secondary phases comprising the steps of providing a high level waste for vitrification; providing a glass frit additive for mixing with the high level waste; providing at least one glass frit constituent selected from the group consisting of AI 2 O 3 , B 2 O 3 , and SiO 2 separately from the glass frit additive for mixing with the high level waste; and, feeding the high level waste, the glass frit additive and the glass frit constituent to a melter to form a mixture for vitrification of the high level waste in which formation of secondary phases is suppressed.
- the method includes the step of providing the glass frit additive in the form selected from the group consisting of glass beads, cylindrical glass fiber cartridges, glass powder, and glass flakes.
- the method includes the step of redistributing selected components of the glass frit additive into individual glass frit constituents for mixing as raw chemicals with the high level waste separately from the glass frit additive. [0018] In a further advantageous embodiment, the method includes the step of redistributing all components of the glass frit additive into individual glass frit constituents for mixing as raw chemicals with the high level waste.
- the method includes the step of providing the glass frit additive having AI 2 O 3 , B 2 O 3 , and SiO 2 , and redistributing at least a portion of at least one of the AI 2 O 3 , B 2 O 3 , and SiO 2 from the glass frit additive to provide at least one redistributed glass frit constituent for mixing separately as raw chemicals with the high level waste.
- the method includes the step of redistributing all of the AI 2 O 3 and a portion of the B 2 O 3 from the glass frit additive to individual glass frit constituents for mixing separately with the high level waste so that the removed AI 2 O 3 and B 2 O 3 totals approximately at least 7wt% by weight of the mixture.
- the method includes the step of combining 15.81wt% of the high level waste, 77.29wt% of the glass frit additive, and 6.9wt% of the AI 2 O 3 and B 2 O 3 for feeding to the melter.
- the method includes the step of redistributing all of the AI 2 O 3 and a portion of the B 2 O 3 and the SiO 2 from the glass frit additive to individual glass frit constituents for mixing separately with the high level waste so that the removed AbO 3 and B 2 O 3 totals approximately 7wt% and the SiO 2 totals approximately 7wt% of the mixture.
- the method includes the step of combining 15.81wt% of the high level waste, 70.56wt% of the glass frit additive, 6.9wt% of the redistributed AI 2 O 3 and B 2 O 3 and 6.73wt% of the redistributed SiO 2 for feeding to the melter.
- the method includes the step of separately feeding the high level waste, the glass frit additive and the at least one glass frit constituent to the melter.
- the method includes the step of mixing the high level waste, the glass frit additive and the at least one glass frit constituenttogether and feeding the resulting mixture to the melter. [0026] In a further advantageous embodiment, the method includes the step of mixing the high level waste with the at least one glass frit constituent prior to feeding to the melter.
- the method includes the step of providing the high level waste, the glass frit additive, and the at least one glass frit constituent in powder form for feeding to the melter.
- a composition is made according to the method described above comprising about 15wt% of the high level waste, about 70%-78wt% of the glass frit additive, and about 7wt%-15wt% of the glass frit constituent selected from the group consisting of AI 2 O 3 , B 2 O 3 , and SiO 2 for feeding to a melter to form a borosilicate glass compound.
- Figure 1 shows a flow chart of the method for mitigation of secondary phase formation during waste vitrification according to the present invention.
- oxide compositions were formed by combining 15.81 wt% of High Level Waste (HLW) simulant and 84.19 wt% of glass frit.
- the HLW simulant contained about 8.64 wt% of MoO 3 for conducting the process discussed herein.
- the glass composition used in the studies had a waste loading of 15.81 wt%.
- the resulting glass had MoO 3 concentration of 1.37 wt%.
- Additives for mixing with the waste material were provided in the form of pre-melted glass frit beads.
- the 15.81wt % of HLW simulant is provided in slurry form.
- JHCM Joule Heated Ceramic Melter
- Removal of B 2 O 3 from the glass frit comprises the remainder of the 10% by weight being removed from the glass frit. In total, removal of all the Al 2 O 3 and a portion of the B 2 O 3 comprises 10% by weight of the total glass frit.
- the target glass composition was obtained by combining 15.81 wt% of HLW simulant , 77.29 wt% of the modified glass frit , and 6.9 wt% of the removed AI 2 O 3 and B 2 O 3 . The waste loading and the final glass composition were unchanged as desired. At the end of the test, examination showed the melter glass to be free of separate molybdate phases.
- the target glass composition was obtained by combining 15.81 wt% of HLW simulant, 70.56 wt% of the modified glass frit , 6.9 wt% of the removed AI 2 O 3 and B 2 O 3 and 6.73 wt% of removed SiO 2 .
- the waste loading and the final glass composition were unchanged as desired. Examination of the heat treated crucible glass samples showed them to be free of separate molybdate phases.
- a method for vitrification of high level waste to reduce the formation of persistent secondary phases comprises the steps of providing about 15% of a high level waste for vitrification (16); providing about 85% of a glass frit additive for mixing with the high level waste (10); redistributing at least about 7%-15% by weight of the glass frit constituents (14) for mixing separately with the high level waste so that less than approximately 70%-78% of the total mixture comprises the glass frit (12); and, feeding the high level waste, the glass frit, and the redistributed glass frit constituents to a melter (18) for vitrification of the high level waste so that formation of secondary phases is suppressed.
- the above innovations can be implemented in any and all of the following glass making processes: 1) JHCM in which the glass frit and HLW slurry with the redistributed glass frit components are fed separately to the melter; 2) JHCM in which the glass frit and HLW slurry with the redistributed glass frit components are mixed and fed together to the melter; 3) JHCM in which the glass frit, the redistributed glass frit components and calcined HLW are fed to the melter as solid powders; 4) Cold Crucible Melters (CCM) in which the glass frit and HLW slurry with the redistributed glass frit components are fed separately to the melter;
- CCM Cold Crucible Melters
