How can Holtec decommission in only a few years when other plants seem to take longer?

Part of decommissioning is moving the spent nuclear fuel from the spent fuel pool to an onsite dry storage facility called an Independent Spent Fuel Storage Installation (or ISFSI) which used to take five or more years after reactor shutdown. Holtec has dry storage systems, which allow the transfer to be done in less than three years. With the spent nuclear fuel on the ISFSI, other decommissioning activities can be safely started sooner and performed more efficiently.
