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.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Nuclear supply chain innovation and collaboration: Keeping the nuclear supply chain viable through change
The next nuclear renaissance may be upon us, but with it comes a perfect storm. The industry is unprepared for a surge in demand for goods and services from both the existing light water fleet and the next generation of reactors. We are currently teetering on the edge of severe supply chain issues, but if the nuclear industry can understand the sources of our challenges, we can mitigate them.

This paper describes characteristics of end loss electrons (ELE's) from a tandem mirror. Without electron cyclotron resonance heating (plug ECRH), ELE's issue from an ICRF heated hot ion plasma. Their temperature increases with the hot ion diamagnetism. Drag heating of electrons on hot ions balances with axial loss due to Coulomb scattering. Landau damping of an Alfvén ion cyclotron wave is also observed in this phase. On application of the plug ECRH, an intense loss flux of warm electrons is generated The axial heat flow carried by the warm electrons significantly increases. Control of the axial flux of the warm electrons is tried A highly transparent mesh is put up over an end plate and a bias voltage negative to the end plate is applied to the mesh. Then secondary electrons emitted from the end plate are suppressed and the loss flux of the warm electrons decreases to about one third of that without the mesh bias. This reduction factor is much smaller than the value expected from the rate of ion plugging. A possible cause of this is an ion current through a plasma behind the end plate.
