Radioactivity as a Function of Time

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. After cooling 5 years, all fuel in storage casks. Remove cooling water pipes. Seal up reactor internals and wait. Revise license.

TLG Projected Costs to Decom VY

What must be done?1. 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.

2. Safe, careful dismantlement must start asap. No guarantee SAFSTOR will lead to sufficient decom fund. The financial risk is too high.

3. Sufficient funds must be available to dismantle the reactor, dispose of waste, including fuel and bring the VY site to greenfield condition.

4. VT must do an independent economic audit, and ensure the decom fund is fully funded.
