Explore waysides and exhibit panels in Hanford's B Reactor. The B Reactor was the first full-scale plutonium production reactor in the world. Reaching criticality in September of 1944, the B Reactor's sole purpose during the Manhattan Project was to produce plutonium for the Gadget, the world's first atomic test device, and for Fat Man, the plutonium-fueled atomic bomb dropped on Nagasaki, Japan on August 9, 1945.

The exhibit panels at the B Reactor are located in three separate rooms. Follow the links below to view the panels room-by-room.
