The Princess Royal is to next month open a unique £20m nuclear archive in Caithness.
The collection holds records from 17 UK sites dating back to the 1940s and went on public show for the first time last year.
The Nuclear Decommissioning Authority (NDA) has funded the centre in Wick, close to one of the country’s earliest nuclear research sites at Dounreay.
Now the Princess is to officially open the Nucleus National Civil Nuclear Archive at Wick Airport on March 19.
Around 20 staff are employed at the archive which houses nuclear records, with thousands of plans, photographs and 200 tonnes of paperwork due to be transferred from other sites over the next few years.
The Princess Royal, as patron of Scottish Rugby Union, will also open Highland Rugby Club’s clubhouse and pitches at Canal Park, Bught Lane, Inverness, the same day.
