Q

nuclear reactor

A

structure which encloses the nuclear fuel which heats water to generate steam which turns a turbine
uranium fuel is processed into pellets which are then put into the fuel rods
control rods can be lowered over the fuel rods to absorb excess neutrons and slow or stop the fission reaction

Q

Yucca Mountain

A

site in Nevada identified as a potential long term storage site for high-level nuclear waste
the project was cancelled in 2012

Q

breeder nuclear fission

A

process of bombarding a radioactive isotope, usually of uranium, with neutrons causing the atom to break apart, releasing a great deal of energy

21
Q

nuclear fusion

A

using very high levels of heat energy (100 million deg C) to force two different atomic isotopes of hydrogen to fuse together
