No nuclear plant I know of uses weapons grade fissile material. This is strictly controlled for military use only.
Nuclear weapons fall under the field of nuclear physics and nuclear engineering, which involve the study of atomic nuclei and the application of nuclear reactions for various purposes, including energy production and weapon development. Additionally, strategic studies and political science are also relevant in understanding the impact and implications of nuclear weapons.
