Between 2010 and 2018, the National Nuclear Security Administration (NNSA) gathered sufficient nuclear material for the construction of 160 bombs. This activity emphasizes the significant role of the Department of Energy (DOE) in nuclear security. The department's efforts are crucial in monitoring nuclear materials worldwide to prevent potential misuse.

Moreover, the DOE trains all international atomic-energy inspectors, ensuring that nuclear power plants operate safely and do not engage in the covert production of weapons-grade materials. These trained inspectors play a vital role in overseeing the processes involving spent fuel and plutonium recovery, thereby maintaining global nuclear stability.
