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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The High Average Power Laser (HAPL) power plant has targets that are directly driven by forty KrF laser beams. Three-dimensional neutronics calculations were performed directly in the exact CAD model of the HAPL final optics system to assess the impact of the biological shielding configuration on the nuclear environment at the GIMM and dielectric focusing and turning mirrors. In the initial configuration, the biological shield fully encloses the GIMM sand associated dielectric mirrors. We assessed another configuration where the shield is moved farther from the target to fully enclose the dielectric mirrors leaving the GIMM in the open space between the chamber and the biological shield. A variation of this configuration utilizes 40 neutron traps attached to the inner surface of the biological shield behind the GIMMs. It is concluded that the shielding configuration with all optics including the GIMM being fully enclosed in the biological shield is the preferred option since it results in the lowest nuclear environment at the dielectric mirrors, provides better GIMM support, reduces the volume to be maintained under vacuum, and requires the least amount of concrete shield.
