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.

Geological work begins on Poland’s first nuclear plant
Project management firm Bechtel started site geological surveys for Poland’s first nuclear power plant project, the company announced on Wednesday.
Bechtel will conduct in-depth geological surveys at the Lubiatowo-Kopalino site in the Pomeranian municipality of Choczewo, in northern Poland. This is a key milestone for the country’s entry into nuclear power production, as the surveys will inform the suitability of the planned site.

In a fusion reactor, almost 30% of fusion energy is deposited on plasma facing components. In the divertor region, it is, however, difficult to utilize this energy with conventional cooling techniques based on high velocity flow with highly subcooled cooling. From this viewpoint, the authors have been developing a cooling technique with metal porous media. In this study, in order to attain both the higher cooling performance and the acquisition of high density energy, high heat removal experiments are performed by using homogeneous and functionally graded porous media to estimate their fundamental heat transfer performances. From the experiments with the homogeneous porous media, it is clarified that the cooling performance is not always improved by using finer pore size media. The functionally graded porous media can reduce a pressure loss. Additionally, in case of the functionally graded porous media with the finer pore, the heat transfer coefficient is higher than that obtained in the homogeneous case. As for the optimal design, it is important to consider the degree of vapor development near a heated surface in the porous media and an effective discharge of vapor from the heated region.
