the construction of the bomb were plants to make the radioactive material needed to construct the bomb. Oak Ridge, Tennessee was used to make uranium which was used as an explosive to react with plutonium. The plutonium itself was made in Hanford, Washington.5 To make this explosion possible, a piece of uranium was fired at another piece of uranium to make the critical mass that was needed for an explosion. Critical mass is the exact amount of fissionable material needed to maintain a fission chain reaction. Once Critical mass was obtained it compressed Plutonium and when the Plutonium was compressed enough, atoms from plutonium were split and it made an explosive bomb that could destroy a ...
