What is nuclear energy
Nuclear energy is the energy in the nucleus, or core, of an
atom. Atoms are tiny units that make up all matter in the universe.
Energy is what holds the nucleus together. There is a huge amount
of power in an atom's dense nucleus. Nuclear energy is seen when
nuclear fusions or fissions happen.

No it is not bad, as some ladies have a heavy period for one
month and then a light one or they may have two heavy periods and
then one light one also.
