Currently for Power Plants in USA
" Decommissioning of closed units proceeding well 2 plants have terminated their licenses
- significant progress at other plants
- transfer of fuel to dry storage completed
- funding appears to be adequate in most cases
- completion of several plant projects in next 1-2 years
" Remaining issues
- Final site characterization
- License termination and site release
- Materials clearance
- Groundwater contamination/ soil remediation 0 2005 Electric Power Research Institute, Inc. All rights reserved.
