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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

The multilayered blanket concept introduced initially in spherical geometry has been extended to tokamak geometry, which has been approximated by an annular disk geometry for the present calculations. Tritium production is determined, using such commonly available materials as lead, natural lithium, and graphite/water. The Morse-E general geometry package is employed to simulate the blanket geometry and the plasma region where the neutrons are produced. Calculations are performed for both the block- and the multilayered-type blanket configurations. Using water as a moderator/reflector, the multilayered arrangement gives a 75% higher tritium production compared to the block-type blanket with the same overall size of assembly. The advantage in tritium breeding due to the multilayered arrangement remains practically the same when 10 vol% stainless steel structural material is used; however, the absolute value of tritium breeding decreases by 6 to 8%. Calculations are reported for a homogeneous, block, and multilayered arrangement of materials. Using lead, natural lithium, and water in the annular disk geometry, an overall thickness of 35 cm would be sufficient to give tritium breeding of 1.32/source neutron.
