Public asked to rank attributes for waste review

Dounreay is inviting organisations and members of the public to help it decide how certain types of waste from decommissioning should be managed in future.

A consultation document published by Dounreay Site Restoration Ltd seeks views on the relative importance of criteria that will be used to assess options for each type of waste.

The closing date for comment is January 31, 2009.

A previous study carried out in 2003 identified 268 waste streams that were categorised under one of 36 headings.

A workshop held as part of the latest  review found that many of the practices used by Dounreay compared favourably with international experience.

A number of waste streams, such as the raffinate from historical reprocessing, were the subject of earlier consultations.

The workshop identified a number of intermediate-level and low-level waste streams that it recommended should be the subject of wider consultation.

These cover different types of graphite, sludges, granular material and putrescent items.

The consultation aims to gather the views of the public about the relative importance of factors such as health and safety, environmental impact and cost when scoring the options for each.

The review is due for completion by June 2009. It is being carried out in support of the authorisation granted to Dounreay under the Radioactive Substances Act 1993, which governs the management of radioactive waste.
