  1. Management of Spent Nuclear Fuel By: Matthew R. MacDougall Nuclear Engineer of Oregon State University Sponsored by American Nuclear Society August 1st, 2012

  2. Background • Policies to date • Applications • Recommendations Overview

  3. Decrease dependence of fossil fuels • 1 fuel pellet equals… • Bad part: produces spent nuclear fuel Issue Definition

  4. Low level • Transuranic (medium) • High level Types of Waste

  5. Product of the Fission Process • Contains 2 main types of isotopes • Actinides (Pu-240, U-238, Th-232) • Fission Products (Tc-99, I-129, Cs-137) Spent Nuclear Fuel

  6. Fuel Flow Chart New Fuel Reactor Temporary On Site Storage Interim Storage Site Final Repository Reprocess SNF Storage Methods

  7. Nuclear Waste Policy Act (1982) • Nuclear Waste Policy Act Amendment (1987) • Both need amending to legally pursue a new storage method • Recommendations • Blue Ribbon Commission • Appointed by DOE • 8 recommendations on SNF management Governmental Policies To Date

  8. 3 Main Agencies Dictated by NWPA • Department of Energy (DOE) • Nuclear Regulatory Commission (NRC) • Environmental Protection Agency (EPA) Overseeing Groups

  9. Nuclear Waste Fund • Safety • Not In My Backyard (NIMBY) • Consent from state Interests And Values At Stake

  10. Dry cask storage • Minimal transportation • Using reactor security • Small space available Policy AlternativesOn-Site Storage

  11. One of the recommendations by BRC • ‘Staging Area’ • Consolidate waste - safer • Takes some pressure off DOE • Transportation still an issue • Needs self security and construction Policy AlternativesInterim Consolidated Storage

  12. Biggest convenience of on-site storage (lack of transportation) • No spills thus far • Tests • Fuel Cask Testing • Terrorism • Blow up casks • Stealing • Self-protecting Transporting Issues

  13. Very confusing • Lots of policies up in the air • Closing of YM Policy AlternativesLong-Term Storage

  14. Carlsbad, New Mexico • Storage of Transuranic Waste • Example of successful storage • Very different than HLW though • Environmental Evaluation Group (EEG) • Way of promoting consent Waste Isolation Pilot Program

  15. SNF • Increasing issue • Can’t keep on putting it off • Repository necessary • Interim storage • Safe, consolidated storage • Transportation very safe • Long time to construct implement, need to start now! Recommendations
