Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

A new class of helium-cooled high heat-flux plasma facing heat exchanger (HX) concept is presented. These unique "Foam-In-Tube" HX concepts are composed of a thin tungsten shell integrally bonded to an open-cell tungsten foam core. High heat flux tests show maximum heat loads of 22.4 MW/m2 using 4 MPa helium at a flow rate of 27 g/s. Based on these impressive performance results, a unique and scalable heat exchanger channel with ultra-low pressure drop through the porous foam is presented. The primary advantage of the new concept is that pressure drop through the porous media and structure temperatures are nearly independent of HX tube length. The concept is modular in design and can be combined to meet divertor size requirements. From a manufacturing and reliability point of view, the advantage of the proposed concept is that it minimizes the need for joining to other functional materials.
