A wildfire burned an estimated 3,000 acres on the Hanford nuclear reservation early Saturday morning, and a larger fire was burning uncontained on Saddle Mountain.
The nuclear reservation fire burned to the east of Highway 240 in the southern end of Hanford, said Rae Moss, spokeswoman for Hanford contractor Mission Support Alliance.
No buildings or areas with radioactive waste were involved, she said.
The fire was discovered about 3:20 a.m. and the Hanford Fire Department had it contained at 6:50 a.m., according to Mission Support Alliance
Highway 240 was closed from Highway 225 to the Highway 24 until about 4:30 a.m., according to the Washington Department of Transportation.
Hanford workers were told to use the Wye Barricade entrance to the site just north of Richland rather than the Yakima Barricade secure entrance.
