Experience with a joule heated ceramic melter while converting simulated high-level waste to glass

Description: Development of a joule-heated ceramic melter, sponsored by the Energy Research and Development Administration, has been progressing for nearly 3 years. In January 1975, a ceramic-lined, direct joule-heated glass melter was started up and operated continuously for nearly 11 months. During this period, process testing was completed both while feeding simulated high-level waste calcine and while feeding simulated high-level liquid waste. While feeding waste calcine and frit, the unit was demonstra… more

Liquid-fed ceramic melter: a general description report

Description: The Pacific Northwest Laboratory is conducting several research and development programs for the solidification of high-level wastes. The liquid-fed ceramic melter (LFCM) is a major component in the solidification process. This melter can solidify liquid high-level waste, as well as melt calcined waste with glass additives and then solidify the mixture. This report describes the LFCM system and shows the main features of the refractories, electrodes and power systems, melter box and lid, draini… more

Assessment of water/glass interactions in waste glass melter operation

Description: A study was made to assess the possibility of a vapor explosion in a liquid-fed glass melter and during off-standard conditions for other vitrification processes. The glass melter considered is one designed for the vitrification of high-level nuclear wastes and is comprised of a ceramic-lined cavity with electrodes for joule heating and processing equipment required to add feed and withdraw glass. Vapor explosions needed to be considered because experience in other industrial processes has show… more

Experience with waste vitrification systems at Battelle-Northwest

Description: Three types of melters; in-can, continuous metallic, and joule-heated ceramic are being developed on an engineering scale for conversion of simulated high-level radioactive waste to a glass form. Work with each of the three melters has progressed for over a year, and ton quantities of glass have been produced. The operation and performance of these systems are described. (auth)

Preliminary estimates of cost savings for defense high level waste vitrification options

Description: The potential for realizing cost savings in the disposal of defense high-level waste through process and design modificatins has been considered. Proposed modifications range from simple changes in the canister design to development of an advanced melter capable of processing glass with a higher waste loading. Preliminary calculations estimate the total disposal cost (not including capital or operating costs) for defense high-level waste to be about $7.9 billion dollars for the reference condit… more

Vitrification and waste glass compositional limits

Description: The most important issue when evaluating the suitability of a waste stream for vitrification is the composition of the waste. Appropriate analytical data are required to ensure that adequate information is available for evaluating and implementing the technology. Although vitrification can be used to immobilize almost any waste stream through dilution of the waste with glass formers, it may be too costly for certain limiting conditions. This report provides guidelines of these limit sand the co… more

Vitrification: Destroying and immobilizing hazardous wastes

Description: Researchers at the US Department of Energy`s Pacific Northwest Laboratory (PNL) have led the development of vitrification a versatile adaptable process that transforms waste solutions, slurries, moist powder and/or dry solids into a chemically durable glass form. The glass form can be safely disposed or used for other purposes, such as construction material if non-radioactive. The feed used in the process can be either combustible or non-combustible. Organic compounds are decomposed in the melt… more

Noble metals-compatible melter features development Phase 1: Establishing functional and design criteria and design concepts

Description: Premature failures have occurred in melters at Japan`s Tokai Mockup Facility and at the Federal Republic of Germany (FRG) PAMELA plant during processing of feeds with high levels of noble metals. Melter failure was due to the accumulation of an electrically conductive, noble metals-containing precipitates in the glass, that then resulted in short circuiting of the electrodes. A comparison was made of the anticipated Hanford Waste Vitrification Plant (HWVP) feed with the feeds processed in the F… more

Vitrification of Hanford wastes in a joule-heated ceramic melter and evaluation of resultant canisterized product

Description: Experience gained in the week-long vitrification test and characterization of the glass produced in the run support the following conclusions: The Hanford waste simulated in this test can be readily vitrified in a joule-heated ceramic melter. Physical properties of the molten glass were entirely compatible with melter operation. The average feed rate of 106 kg/h is high enough to make the ceramic melter a feasible piece of equipment for vitrifying Hanford wastes. The glass produced in this tria… more

Database for waste glass composition and properties

Description: A database of waste glass composition and properties, called PNL Waste Glass Database, has been developed. The source of data is published literature and files from projects funded by the US Department of Energy. The glass data have been organized into categories and corresponding data files have been prepared. These categories are glass chemical composition, thermal properties, leaching data, waste composition, glass radionuclide composition and crystallinity data. The data files are compatibl… more
