Changes

:*[[Intermediate Level Nuclear Waste]] - '''Waste''' with a long [[Half Life|half life]] and a medium level of [[radioactivity]] so it requires shielding, but does not require cooling.

:*[[High Level Nuclear Waste]] - '''Waste''' which extremely [[radioactive]] but will not remain so for more than a few decades due to a short [[Half Life|half life]]. After around 50 years this becomes [[Intermediate Level Nuclear Waste]]. It requires shielding and cooling to prevent it heating up so much that [[Melting|melts]] or catches fire.
