Nucleus: The Nuclear and Caithness Archive Travel Guide

Nucleus: The Nuclear and Caithness Archives serves as the central archive for the British civil nuclear industry and the historical records of the Caithness region. Situated at Wick Airport, this purpose-built facility consolidates nuclear records previously scattered across multiple UK sites, including Dounreay, Harwell, Trawsfynydd, and Sellafield. The nuclear archives span over seventy years and comprise plans, drawings, photographs, films, microfiche, and official documents. Alongside these, the Caithness archives hold documents dating back to 1469, including charters, minute books, correspondence, maps, and photographs, offering a rich resource for local and family history research.

The archive opened in 2017 in a building designed to meet stringent UK archival standards. It provides a welcoming public searchroom open Monday to Friday from 10am to 4pm, where visitors can access a wide range of materials including microfilm readers and public access computers. The facility also features exhibition spaces showcasing local heritage. Visitors are encouraged to pre-book research times and specific documents, but drop-in visitors are also accommodated. Free parking is available on-site and at an overflow car park nearby. The archive staff offer assistance in navigating the collections and can undertake remote research services for a fee.

Nucleus holds the official archives for the county of Caithness, making it a vital center for genealogists and historians interested in the area. The collections include centuries-old maps, property histories, and family records, enabling deep exploration of local heritage. The archive’s integration of nuclear industry and regional history reflects the area's socio-economic ties to nuclear decommissioning, particularly following the closure of the Dounreay site. This dual focus ensures the preservation and accessibility of both industrial and cultural memory.

The establishment of Nucleus has contributed significantly to the local economy, creating permanent jobs and opportunities for local contractors during its construction. Managed by Restore Scan Ltd, the archive supports the community by sustaining interest in Caithness history and the UK nuclear legacy. It also serves as an educational resource and a cultural hub, fostering connections between past and present.

Visitors to Nucleus can expect a well-equipped research environment with access to extensive archival catalogs and secondary sources.

The archive offers family history consultations, both in-person and virtual, and remote research services. It is closed on weekends and public holidays, so checking ahead is recommended.
