Nucleus, the Nuclear and Caithness Archives () is the national archive of the British civil nuclear industry and the archive for the County of Caithness. The archives were constructed by the Nuclear Decommissioning Authority (NDA) and opened in 2017. Work continues at the facility to bring together all of the NDA's archive material from 16 separate sites. The Caithness county archives, dating from 1589 are also held at the site. Building The archives are housed on former Royal Air Force land adjacent to Wick Airport in Caithness, North-East Scotland. The facility was constructed by the Nuclear Decommissioning Authority (NDA) at the cost of £21 million. The site was chosen from a shortlist of four areas selected by the NDA as being affected by the decommissioning of nuclear power stations. More than 2,000 people in the local area are working to decommission the former nuclear facilities at Dounreay in a project set to complete in 2030. The establishment of the archives will create 25 permanent jobs in the area, the majority of which can be filled by members of the local community. The facility was constructed under a design and build contract by Morrison Construction. The design was carried out by Reiach and Hall Architects who won the Architects' Journal 2017 Editor's Choice Award for their work. It consists of a two-storey concrete archive building and a separate single-storey administration and publicly-accessible building. The buildings are clad in silver-anodised aluminium and the grounds contain "lochan" (small lochs) water features. The facility opened in February 2017. Archives Nucleus holds the national archive of the UK civil nuclear industry and the county archive for Caithness. The site is managed by High Life Highland, an arm of the Highland Council. The archives are made available for public access. The site will also become a training centre for archivists, with links to the University of the Highlands and Islands and the North Highland College. The archives are in the process of being digitised by Restore Digital to allow online access. Nuclear archive The UK nuclear industry archive was previously spread around at least 16 separate sites, often in buildings associated with current or former nuclear power stations. The NDA began looking for a suitable site to accommodate the consolidated records in 2005. Since the opening of Nucleus records have begun to be transferred there from the other sites. This process began with the transfer of
