-
C.
X-10 graphite reactor
The X-10 graphite reactor was an early nuclear reactor at Oak Ridge, Tennessee, built during the Manhattan Project as a pilot plant for plutonium production and a key step toward the development of nuclear weapons and nuclear energy.
-
D.
K-25 Project
The K-25 Project was a World War II–era Manhattan Project effort to build and operate a massive gaseous diffusion plant for uranium enrichment in Oak Ridge, Tennessee.
-
E.
Trinity test device
