Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Power quality is analyzed for the poloidal field (PF) power supply system of the Experimental Advanced Superconducting Tokamak (EAST) device. It is found that the power quality is quite different when the four-quarter PF power system is working in different operation modes. The (6k±1)’th (k is the odd number) harmonics are dominant during the electricity-cost phase while the (6k±1)’th (k is the even number) harmonics exist abundantly during the electricity-generation stage. In addition, fast Fourier transform as the data analysis method is applied to process harmonics and interharmonics. The experimental results present the characteristics of waveform and of current and power, and they show the emission features of harmonics and interharmonics, which leads to the conclusion that the energy of interharmonics and spectrum leakage caused by the harmonic clustering algorithm is recovered to an integer or that the picket fence effect results in the spectrum leakage of interharmonics.
