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.

Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

The fusion reactor fueled by deuterium and tritium will generate many neutron activation products, causing occupational exposure and radiation risk. The minimization of occupational radiation exposure (ORE) is one of the safety goals for fusion reactors. However, detailed designs and management schemes are still lacking for fusion reactors, and the ORE evaluations are still well simplified. In this paper, an integrated assessment approach is proposed for fusion reactors at the conceptual or detailed design stage. The core idea is to estimate the ORE by referring to the dose rates and work efforts of mature fission reactors and ITER and modifying the data of these similar systems by a proportional coefficient according to the differences of component scale, operating environment, etc. The results showed that water cooling fusion reactors will generate the highest collective dose of 2635 p-mSv/year, while the PbLi cooling ones come next with about 1684 p-mSv/year and the helium cooling ones are the least. This method will contribute to fusion reactor design, operation, and maintenance optimization at the earlier stages and provide guidance to reduce the overall potential ORE to workers.
