: '''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. ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/019835939X/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=019835939X&linkCode=as2&tag=nrjc-21&linkId=57e96876985fc39b1a3d8a3e3dc238b6 ''Nuclear waste, page 108, GCSE Physics; Third Edition, Oxford University Press, AQA '']:[https://www.amazon.co.uk/gp/product/178294558X/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=178294558X&linkCode=as2&tag=nrjc-21&linkId=f0dfb66dafcb0c6e9449e7b1a4ae1ac342 ''Nuclear waste, page 21, GCSE Physics; The Revision Guide, CGP, AQA '']
