2020-7-29A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind water as

The framework, worth up to 400 million and initially set-up for up to four years, with the possibility of extensions of up to an additional three years, will take work at the site into a new phase when historic wastes from the shaft, silo and low-level waste pits are due to be retrieved, repackaged and consigned to modern waste facilities

Cemented waste rock backfill CWRB, which is a mixture of tailings, waste rock, cement, and water, is subjected to combination actions in underground mining operations and has been widely used in deep resource mining. While the strength requirement and macroscopic deformation behaviors of CWRB have been well studied, the mesoscopic damage evolution mechanisms are still not well understood

2020-1-15Toward Decommissioning of Nuclear Facilities and Radioactive Waste Management Fig.8-1 Outline of low-level radioactive waste management The research and development of the decommissioning of nuclear facilities and the processing of radioactive wastes, including waste treatment and waste characteriation, have been promoted. Approach to radioactive

A waste treatment apparatus treats radioactive contaminated waste from a nuclear fuel material handling facility to decontaminate the radioactive contaminated waste by using an electrolytic molten salt, and reuses the electrolytic molten salt so that any effluents are not produced. Radioactive contaminated waste 10 from a nuclear fuel material handling facility is subjected to electrolysis

The invention relates to a method and system for the treatment of radioactive wastes produced as a consequence of the operation of nuclear power plants with pressuried water reactors and boron reactivity regulation accompanied by the simultaneous production of environmentally acceptable substances of, for example, borax, calcium-magnesium borates, boron acid and sodium hydroxide

The main immobiliation technologies that are available commercially and have been demonstrated to be viable are cementation, bituminiation, and vitrification. Vitrification is currently the most widely used technology for the treatment of high level radioactive wastes HLW throughout the world. Most of the nations that have generated HLW are immobiliing in either alkali borosilicate glass

Abstract. Cementitious materials are essential parts in any radioactive waste disposal facility either shallow or deep underground facilities. Despite these materials having been extensively used and studied, there is still a need to investigate and understand their long-term behavior due to the fact that disposal is a passive system and regulatory requirements for the safe disposal range
