ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

Future job opportunities highlight Friday Plenary at ANS Student Conference
The second day of the 2021 ANS Virtual Student Conference, on April 9, hosted by North Carolina State University opened with the plenary, “Student Opportunities within the Nuclear Community.” The session featured three panelists, each representing a different sector of the nuclear community.
If the nucleus of a heavy atom–such as uranium–absorbs a neutron, the nucleus can become unstable and split. This is called nuclear fission. Fission releases energy in the form of heat. Although fission can occur naturally, fission as encountered in the modern world is usually a deliberate man-made nuclear reaction.
Typical fission events release about two hundred million eV (200 MeV) of energy. In contrast, most chemical oxidation reactions (such as burning coal) release at most a few eV per event. So, nuclear fuel contains at least ten million times more usable energy per unit mass than does chemical fuel.
Fusion is the opposite reaction of fission. In fusion, atoms are fused together.For a fusion reaction to occur, it is necessary to bring two nuclei so close that nuclear forces become active and glue the nuclei together. Deuterium and Tritium, isotopes of hydrogen, are used in fusion reactors. Nuclear forces are small-distance forces and have to act against the electrostatic forces where positively charged nuclei repel each other. This is the reason nuclear fusion reactions occur mostly in high density, high temperature environment.
Recreating that environment is the greatest challenge to producing commercial scale fusion energy, but it’s a challenge well worth pursuing. Nuclear fusion can produce four times the amount of energy as nuclear fission.
