DECOMMISSIONING

To remove nuclear facilities from service and to reduce residral radioactivity to a level allowing unrestricted use.
Removal of spent fuel is considered to be an operational activity, so not included in decommissioning
Non-radioactive structures and materials aren't involved
~%85 of a nuclear power plant is not radioactive
~%99 of radioactivity is shipped away as spent fuel and low level waste right after shut down.
