Nuclear reactors are primarily used to generate electricity by harnessing the energy released from nuclear fission.

Pressurized water reactors (PWRs) are the most common type of nuclear reactor in the world, accounting for over two-thirds of all operating reactors.

Nuclear engineers are responsible for the design, construction, and operation of nuclear reactors and other nuclear facilities.

Nuclear physicists study the structure and properties of atomic nuclei, including their composition, energy levels, and interactions.

Nuclear chemists study the chemical properties of radioactive materials, including their behavior in the environment and their interactions with other chemicals.

Nuclear power plants are associated with a number of safety concerns, including the risk of a nuclear meltdown, the release of radioactive materials into the environment, and the disposal of nuclear waste.

Spent nuclear fuel is the most common type of nuclear waste, accounting for over 90% of all radioactive waste generated by nuclear power plants.

Burial in deep geological repositories is the most common method for disposing of nuclear waste, as it provides a long-term, safe solution for isolating radioactive materials from the environment.

Nuclear energy is expected to continue to be a major source of electricity in the future, as it provides a reliable and low-carbon source of energy.

The nuclear industry faces a number of challenges, including the high cost of building and operating nuclear power plants, the long construction times for nuclear power plants, the safety concerns associated with nuclear power plants, and the disposal of nuclear waste.
