Fire at Dounreay led to release of radioactivity | Fire at Dounreay led to release of radioactivity |
(35 minutes later) | |
A fire in part of Dounreay's Prototype Fast Reactor (PFR) facility last month led to an "unauthorised release" of radioactivity into the environment. | |
Dounreay Site Restoration Limited (DSRL) said "procedural non-compliances and behavioural practices" by staff led to the incident on 7 October. | |
DSRL said trace amounts of tritium were released and did not pose a risk to the public. | |
No-one at the plant was hurt in the early morning incident. | |
The Caithness site's fire brigade extinguished the blaze in the PFR's sodium tank farm within 30 minutes. | The Caithness site's fire brigade extinguished the blaze in the PFR's sodium tank farm within 30 minutes. |

The incident happened on the same day a blaze broke out on a ship transporting radioactive waste from Dounreay to Belgium. | |
The blaze started in one of the MV Parida's two funnels on the night of 7 October. | |
It lost power and started drifting towards an oil platform in the Moray Firth. Fifty-two people on the rig were evacuated as a precaution. | |
Following repairs the ship was able to resume its journey. |
