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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

The progress of modern detector arrays was based on their good angular resolution, which has a great impact on gamma-ray spectroscopy with relativistic fragmentation beams and, thus, allows studies of the most exotic nuclei and discovery of superdeformed states of high spins. Recently, a fast timing array was designed for the future Facility for Antiproton and Ion Research for studying the very short-lived nuclei (of several subnanoseconds) at the extremes of existence. For this purpose, several gamma-ray detector array geometries were designed and simulated to maximize the solid angle and enhance the timing precision and efficiencies. Therefore, the probability correction approach has been applied in the present work to calibrate the newly designed gamma-ray conical array for the fast timing array. The calculated full-energy peak efficiency values for the array were compared to the simulated ones by the GEANT 4 code published in the literature. Results showed a reasonably low-percentage relative difference between the calculated and the reported simulated results <4.5% on average.
