Study Notes
Classifications of Radioactive Waste
- Radioactive waste is classified into three main categories: low-level waste (LLW), intermediate-level waste (ILW), and high-level waste (HLW)
- LLW includes radioactive materials with low radioactivity, such as contaminated clothing and tools
- ILW includes resins, filters, and metal wastes from nuclear reactors
- HLW includes spent nuclear fuel and other highly radioactive materials
Generation of Radioactive Waste
- Radioactive waste can be generated from various activities, including:
- Nuclear power plants
- Nuclear research and development
- Medical and industrial applications
- Uranium mining and milling
Regulation of Radioactive Waste
- Radioactive waste is regulated by national and international authorities to ensure safe handling, storage, and disposal
- Regulations vary by country, but generally include guidelines for waste classification, packaging, and disposal
Nuclear Reprocessing
- Spent nuclear fuel can be recycled in nuclear reprocessing plants to recover usable materials
- Approximately 95% of spent nuclear fuel is recycled in nuclear reprocessing plants
Characteristics of High-Level Waste (HLW)
- HLW is characterized by high radioactivity and heat generation
- HLW requires specialized storage and disposal facilities to prevent environmental contamination and radiation exposure
- HLW includes spent nuclear fuel, which is typically stored in pools or dry casks before permanent disposal
