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