Higher activity waste guidance

The Scottish Government advocates the use of long-term 'near surface near site' storage facilities in Scotland. As intermediate and high level waste both require shielding (the latter also involving cooling), they are currently being stored at nuclear installations until long term storage facilities become available.

Some spent fuel from nuclear reactors is also reprocessed at Sellafield, where potentially re-usable uranium and plutonium are separated from radioactive waste. In the past, some intermediate level waste was disposed of in a disposal shaft at Dounreay.

Guidance

Certain types of radioactive waste produced on nuclear licensed sites need to be treated and packaged (a process referred to as "conditioning"), in order to make them safe for long-term storage and disposal. SEPA and the Health and Safety Executive (HSE) jointly regulate this process on nuclear sites in Scotland. The Environment Agency (EA) and HSE regulate nuclear sites in England and in Wales.

Together with the HSE and EA, SEPA has published the first part of its revised joint guidance to the nuclear industry. This guidance explains to nuclear licensees the process they should follow to obtain regulatory approval for their proposals for conditioning higher activity wastes:

In updating our original guidance (published in 2005), we consulted widely on proposed revisions:
