Explanation

Pitchblende also known by the name uraninite is a mineral comprised mainly of oxides of the element uranium. It is the primary source of uranium. The basic fuel for a nuclear power reactor is uranium, a heavy metal able to release abundant concentrated energy. So, it can be used in atomic reactors to generate electricity. The nuclear power plants use the heat given off during fission as fuel. Fission takes place inside the reactor of a nuclear power plant. At the center of the reactor, the core is present, which contains the uranium fuel.
