Almost 200 community projects in the north of Scotland landed a cash windfall thanks to the safety record of workers at Dounreay.
Staff hit the jackpot for charity when they went a whole year without a lost-time accident.
That earned a maximum £30,000 pay-out from UKAEA Ltd, parent body of site licence company DSRL, which donates £2500 every time the site completes an accident-free month.
The cash went to the Dounreay Communities Fund, which provides financial support for good causes in Caithness and north Sutherland.
During the last 12 months, the fund paid out more than £42,000 to 180 local groups.
Additional donations came from the Nuclear Decommissioning Authority and profits from the sale of a book marking the 50th anniversary of the fast reactor experiment.
