Answer 1

Uranium 235 Is the radioactive material.

Answer 2

Two types of reactions takes place in the nuclear reactor to produce energy:
Nuclear Fission and Nuclear Fusion

In Nuclear Fission, Uranium-235, Plutonium-239, Plutonium-241 and Thorium are used as fuels in the Thermal reactors.
Fast Neutron reactors use fast neutrons to perform fission in their reactors.

In Nuclear Fusion, Hydrogen is used as fuels in reactor to produce neutron particle energy.
