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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

This paper presents the computational performance of microfluidic channels (MFCs) within a semiconductor detector to monitor changes in the elemental and isotopic composition of a UOX pressurized water reactor used nuclear fuel dissolved in a KCl/LiCl molten salt. The results indicate that the use of MFC limits alpha energy loss sufficiently enough to use energy windowing techniques in spectral analysis. It was found that elemental and isotopic changes as low as 1% may be feasible, with the time to detection (TTD) ranging from seconds to hours. The TTD is inversely dependent on the number of MFCs within the sensor and the activity of the element/isotope undergoing concentration transients.
