Nuclear waste

  1. 1. Nuclear Waste Management<br />Presented By:<br />Michael Matticks<br />
  2. 2. Introduction<br />Types of nuclear waste<br />Hazards<br />Management<br />Future<br />Final Thoughts<br />
  3. 3. Types of Nuclear Waste<br />Low-Level Waste<br />Intermediate-Level Waste<br />High-Level Waste<br />
  4. 4. Low-Level Waste<br />Sources<br />Hospitals, Labs, Nuclear Fuel<br />Rags, Tools, Filters<br />Hazards<br />Not very dangerous to handle<br />Minimal radioactivity<br />Short-lived<br />Management<br />Shallow landfills<br />Compacted<br />Incinerated<br />
  5. 5. Intermediate Level Waste<br />Sources<br />Resins, chemical sludge's, reactor components<br />Reactor decommissioning contaminated materials<br />Hazards<br />Higher radioactivity<br />Short-lived and long lived<br />Management<br />Special shielding<br />Solidified in concrete or bitumen<br />Buried – Shallow or deep depending on level.<br />
  6. 6. High-Level Waste<br />Sources<br />Actual used fuel<br />Main waste of reprocessing<br />Hazards<br />Highly radioactive<br />Long-lived<br />Management<br />Shielding<br />Water filled concrete vaults<br />Airtight, steel containers<br />
  7. 7. Future Disposal/Management<br />Integrated Management System<br />Centralized interim storage<br />R&D into recycling<br />Development of permanent storage facility<br />Nuclear Waste Recycling <br />Closed fuel cycle<br />Separated uranium becomes new fuel<br />Repositories<br />Storage of recycling waste<br />Yucca Mountain, NV<br />
  8. 8. Transportation<br />Special Containers<br />Maintain integrity in all conditions (1 ton of fuel to three tons of shielding)<br />Routing<br />Specified highway routes<br />Dedicated trains improve security and transit times<br />
  9. 9. Final Thoughts<br />Radioactive waste created comes in a variety of forms. All of these are potentially dangerous, but with the proper care and procedures, the waste can be managed and even recycled in order to lessen the hazard presented to society. <br />Utility companies and the general population are stakeholders for this issue, as it can potentially have detrimental effects for all if it is not managed correctly, but can have positive outcomes if managed using the proper guidelines.<br />
