Jack Hefner's Interview
S. L. Sanger: This is Hefner on June 11, 1986, interviewed at his residence in Richland.
Jack Hefner: The plant at Oak Ridge was operating to make enough samples of plutonium, so they could learn how to separate here at Hanford. Very few people said a great deal about that and knew much about it. And we only had this manner of need to know. So all our job was keep the plant operating. And the operating people was crank the plutonium out the door.
