Radioactive waste

SEPA is responsible for regulating the disposal of radioactive waste from all sites and it's storage on non nuclear sites. This page tells you about the different levels of radioactive waste and how it is currently stored.

Different levels of waste

There are three types of radioactive waste that must be stored or disposed of in Scotland and the UK. These are low level, intermediate and high level waste.

Low level waste accounts for about 90% of solid radioactive waste produced (by volume) in the UK. It is generally made up of everyday materials, such as plastics, glass, metals and paper, which have come into contact with radioactive liquids or powders. While most of it comes from the nuclear industry, it is also produced by non-nuclear industries, such as hospitals and universities.

Of the remainder, nearly 10% of waste is intermediate and 0.1% high level. Although a relatively small volume, high level waste contains over 95% of the total radioactivity of all nuclear wastes. It is therefore vital that all waste produced as a result of nuclear activity is safely stored and disposed of. 

In September 2001, the UK Government launched a public consultation called "Managing Radioactive Waste Safely". One key outcomes of the consultation was a decision by UK Government to set up the independent Committee on Radioactive Waste Management (CoRWM) in November 2003:
