Study Notes
Dispose Methods
Land Disposal
- Most common method of radioactive waste disposal
- Waste is buried in specially designed facilities, often in deep geological formations
- Multiple barriers prevent leakage:
- Containers or overpacks to prevent leakage
- Engineered barriers (e.g., clay, cement) to slow migration
- Geological barrier (e.g., rock formations) to prevent human exposure
Vitrification
- Waste is mixed with glass-forming materials and melted to create a solid, stable glass
- Reduces waste volume and increases stability
- Can be stored in surface facilities or buried in land disposal sites
Transmutation
- Process of converting long-lived radioactive isotopes into shorter-lived or stable isotopes
- Can reduce waste volume and toxicity
- Still an emerging technology, with ongoing research and development
Storage Facilities
Dry Cask Storage
- Above-ground storage of spent nuclear fuel in dry casks
- Passively cooled, reducing the risk of radioactive releases
- Can be used for long-term storage or temporary storage during transport
Pool Storage
- Spent nuclear fuel is stored in pools of water to cool and shield radiation
- Typically used at nuclear power plants or central storage facilities
- Requires active cooling systems to maintain safety
Geological Repositories
- Long-term storage facilities built deep underground in stable geological formations
- Designed to isolate waste from the biosphere for thousands of years
- Examples: Yucca Mountain (USA), Onkalo (Finland), and others
