Daniel Friel's Interview

Stephane Groueff: So Mr. Friel, you were with the optical side in Chicago project?

Dan Friel: Yes. My interest and activity was in the optical end. The job was to make it possible to see through walls and to see into equipment where otherwise the radioactive level was too high to operator or to work. We knew, of course, that we had to be able to see behind these walls, and we knew in many cases that we would not know what we would be looking at, because there were new and strange phenomena going on. This indeed turned out to be the case.

Hanford, WA

Hanford, Washington, on the beautiful Columbia River, was the site selected for the full-scale plutonium production plant, the B Reactor. Today a popular tourist desination, the Hanford Site proved crucial to the success of the Manhattan Project.
