It could be argued that the use of nuclear power began in the 1950's when a nuclear reactor in the Idaho desert supplied electric power to a local community.
Yes.

The majority of commercial nuclear power reactors use uranium (natural or enriched) as nuclear fuel.
For electricity production, 1956
Commercial power generation predominantly uses nuclear fission as the primary type of nuclear reaction to produce electricity. In nuclear fission, the nucleus of an atom is split into smaller parts, releasing a significant amount of energy in the process. This energy is harnessed to generate electricity in nuclear power plants.
Most commonly used material to produce nuclear energy in Uranium.
