Mine or Mill Processing Radioactive Ores
Mine or Mill Processing Radioactive Ores : Installation for mining, milling or processing ores containing uranium series or thorium series radionuclides. A mine processing radioactive ores is any mine that yields ores containing uranium series or thorium series radionuclides, either in sufficient quantities or concentrations to warrant exploitation or, when present in conjunction with other substances being mined, in quantities or concentrations that require radiation protection measures to be taken as determined by the Regulatory Authority. A mill processing radioactive ores is any facility for processing radioactive ores from a mine processing radioactive ores as here defined to produce a physical or chemical concentrate. This definition from the BSS included those mining and processing operations aimed at extracting uranium series or thorium series radionuclides and those aimed at the extraction of other substances from ore where this represents a significant radiological hazard. Strictly speaking, a mill in the context of the processing of minerals is a facility for the processing of ore to reduce its particle size, especially by crushing or grinding. However, in the context of the BSS definition, the term mill is used in a broader sense to denote a facility in which additional processing - for example, hydrometallurgical processing - may also be carried out. Owing to the possibility of confusion, the use of the word mill in this broader sense, in this expression or elsewhere, is discouraged. This definition has been included for information only. Words are used with their normal dictionary definitions except for the term radioactive. See: Radioactive (meaning 2). minimization, waste: The process of reducing the amount and activity of radioactive waste to a level as low as reasonably achievable, at all stages from the design of a facility or activity to decommissioning, by reducing waste generation and by means such as recycling and reuse, and treatment, with due consideration for secondary as well as primary waste. Should not be confused with volume reduction
