The first law of thermodynamics states that energy can be transformed, but not created nor destroyed. In a nuclear reaction, mass is transformed into energy.
The first country to use nuclear power for electricity generation was the United States. The world's first commercial nuclear power plant, the Shippingport Atomic Power Station, began operation in 1958 in Pennsylvania. This marked a significant milestone in the development of nuclear energy as a source of power.
Humans did not create nuclear energy, it was created shortly after the big bang when the first stars formed and began fusing hydrogen into helium. Later supernova explosions created elements up to uranium, which we can use as fuel in nuclear reactors and nuclear bombs.
The first full-scale commercial nuclear power station was built by Westinghouse at Shippingport PA. It was just recently decommissioned after a long uneventful service life.

Nuclear energy is first changed to heat in a nuclear power plant using a process called nuclear fission. The heat generated is then used to produce steam, which drives turbines to generate electricity.
Not sure what you mean with "transfer into energy". No new energy is created, and no energy is destroyed. Nuclear fission converts nuclear energy (a type of potential energy) available in the atoms, into other types of energy, like heat.
