Dounreay

Dounreay was once Britain's centre for fast reactor research and development. Now the 140-acre site in Caithness is the largest nuclear decommissioning project in Scotland and the second largest in the UK, after Sellafield. Dounreay is planned to be fully decommissioned by 2033.

The Vulcan Naval Reactor Test Establishment, operated by the Ministry of Defence (Procurement Executive), is also located next to the site. The impact of its discharges is considered along with those from Dounreay.

Nuclear Decommissioning Authority (NDA)

As of 1 April 2007, the Dounreay site assets belong to the NDA. The NDA has contracted United Kingdom Atomic Energy Authority (UKAEA) to manage the decommissioning process.

A new site licence company called Dounreay Site Restoration Limited (DSRL) has been formed, who are capable of holding the site licence, the SEPA authorisations and other necessary permits. SEPA is currently determining applications to transfer existing authorisations from UKAEA to DSRL. Initially, the new site licence company belongs to UKAEA. A new parent body organisation, UKAEA Ltd, will become the 'parent' organisation for DRSL pending competition in 2008. The successful bidder is expected to take over ownership of DSRL in 2009.

Issues

Some of the current issues with the Dounreay site include low level waste management, radioactive particles released to the local environment, and the transfer of operational activities from UKAEA to DSRL. Following the statement from Scottish Ministers that low level radioactive waste generated by Dounreay must be dealt with on (or very close to) the site, several challenges exist in building facilities to receive this waste. (The waste includes historic waste and large amount of further waste which will be generated by the site during decommissioning.)  

Proposed Low Level Waste Facilities

In June 2006, the current site operator UKAEA made a planning application to the Highland Council for low level waste disposal facilities. SEPA is a statutory consultee in the process, and we are required to provide a response to the council on the environmental impact of the proposed facility and its use.

Dounreay Particles Advisory Group

The Dounreay Particles Advisory Group makes scientific and technical recommendations to SEPA and UKAEA about ways to improve the monitoring and research programmes for particles in local sediments.

Dounreay Particles Research

SEPA has commissioned research work into the issue of irradiated nuclear fuel particles in the environment around Dounreay.
