→About Nuclear Waste
: '''Nuclear waste''' is produced in [[Nuclear Fission Reactor|nuclear fission reactors]] and must be disposed of safely to prevent [[Radioactive Contamination|contamination]] of the [[environment]] and [[irradiation]] of living [[organism]]s.
: There are three so called 'levels' of [[Nuclear Waste|nuclear waste]]:
:*[[Low Level Nuclear Waste]] - '''Waste''' with a short long [[Half Life|half life]] and but a low level of [[radioactivity]] so does not require shielding or cooling.:*[[Intermediate Level Nuclear Waste]] - '''Waste''' with a short 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''' with a many different which extremely [[Unstable Isotope|unstable isotopesradioactive]] with different but will not remain so for more than a few decades due to a short [[Half Life|half liveslife]] and a high level of . After around 50 years this becomes [[radioactivityIntermediate Level Nuclear Waste]] so it . It requires shielding and cooling to prevent it heating up so much that [[Melting|melts]] or catches fire. High level nuclear waste usually becomes intermediate level nuclear waste after around 50 years.
