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.

The ARIES team is presently studying a fusion power plant based on the spherical tokamak (ST) concept. This paper addresses the key nuclear issues for spherical tokamaks and illustrates the impact of the neutronics factors on the ARIES-ST design. A three-dimensional analysis was carried out for an interim design to determine the key nuclear parameters. Preceding the 3-D analysis, a series of parametric 1-D analyses were performed to guide the design toward the final configuration. Comparing the 1-D and 3-D results, important differences were identified and attributed mainly to the angular distribution of the incident source neutrons on the first wall. Those differences are unique to spherical tokamaks.
