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.

Direct waste transfer process quickens at Savannah River Site
The Department of Energy Office of Environmental Management’s liquid waste contractor at the Savannah River Site this month marked the first direct transfer of decontaminated waste from the Salt Waste Processing Facility (SWPF) to the Saltstone Production Facility (SPF). This is a new step in optimizing waste processing, according to the DOE.

In order to investigate the behavior of hydrogen isotope on the water-metal boundary, a series of deuterium permeation experiment from heavy water vessel through pure iron piping was performed as a function of temperature ranging 423~573 K at 15 MPa. During the experiment, the surface of iron piping was oxidized to magnetite at the heavy water boundary and then deuterium would generate by Schikorr reaction. This deuterium could be detected by mass spectrometer, which monitored the inside gases of the piping under vacuum. The result showed clearly that more than 85 % of the deuterium permeated through the metal piping and detected as deuterium gas (D2) under vacuum. The D2 permeation rate reached some stabilized value as a function of temperature.
