  1. Vermont Yankee

  2. Boiling Water Reactor

  3. Reactor Building Spent fuel pool Concrete 3.8 Ci/m3 (Fe-55, Ca-45) Carbon steel 370 Ci/m3 (Co-60, Fe-55, Mn-54)

  4. Reactor Vessel and Internals 2.9 Million Ci/m3 (Co-60, Fe-55, Cr-51) (0.7 – 3 R/hr)

  5. Radioactivity as a Function of Time

  6. Decommissioning Alternatives • Dismantlement – remove all radioactive materials. Terminate license, except for spent fuel and hot core components. In VT, hopefully return to greenfield. • Safstor – remove much of external contamination. All fuel in storage casks. Remove cooling water pipes. Seal up reactor internals and wait. Revise license.

  7. CT Yankee Dry Storage

  8. Dry Storage Cask

  9. Cask 1.0

  10. Hi-Star 100 Cask

  11. Remaining Amts to Collect

  12. Entergy Misses the Mark

  13. TLG Projected Costs to Decom VY

  14. What must be done? • While the labor force is intact, immediate steps must be taken. VY will have to produce a decom plan for NRC, but we need a site survey now. • Safe, careful dismantlement must start asap. No guarantee SAFSTOR will lead to sufficient decom fund. The financial risk is too high. • Sufficient funds must be available to dismantle the reactor, dispose of waste and bring the VY site to greenfield condition. • VT must do an independent economic audit, and ensure the decom fund is fully funded.
