RICHLAND, Wash. -- The Richland Fire Department and Areva continue to investigate the cause of a small fire Friday at Areva's nuclear fuel production plant in Richland.
Fuel production was delayed for a few hours and the room where the fire was remains closed, said Areva spokeswoman Anna Markham.
The fire was in a self-enclosed air filter system associated with a piece of equipment used for cutting materials. The equipment filter circulates air in a small room within the main processing building of the plant.
Air monitoring of the room detected no abnormal radiation conditions, according to Areva.
