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.

The NCSU electrothermal plasma gun, SIRENS, has been used to evaluate the erosion behavior of plasma-facing components under conditions simulating plasma disruption in tokamaks. The device is capable of producing conditions with heat fluence up to 10 MJ/m2 over 0.1 and 0.25 ms pulse duration. In future large tokamaks, plasma-facing components are expected to receive heat fluxes during a plasma disruption, which may exceed 100 GW/m2 over 0.01–5 ms. The vapor, which is developed at the ablating surface, absorbs a fraction of the incoming plasma energy. Candidate plasma-facing materials have been exposed to heat fluxes in the SIRENS facility (primarily from a blackbody spectrum photons), up to 100 GW/m2 over 0.1–0.25 ms. The vapor shielding effect has been demonstrated and analyzed for the divertor candidate materials.
