Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

NWMO to select Canadian repository site this year
Canada’s Nuclear Waste Management Organization, a not-for-profit organization responsible for the long-term management of the country’s intermediate- and high-level radioactive waste, is set to select a site for a deep geologic repository by the end of the year.

Calculations of the yield of neutrons due to the interaction of protons on a deuterium gas target have been carried out for the primary p - d breakup reaction as well as for the secondary processes due to nuclear reactions induced by the elastically scattered protons and deuterons. The experimental conditions of Bowman et al. reported in a recent work were simulated with respect to the measurements of neutron yields in the proton energy range 7 to 17 MeV. It is found that the primary breakup reaction is the main source of neutron production and the contribution to the neutron yield from the secondary processes is quite small, being of the order of 1% to 2%. Thus, the discrepancy reported by Bowman et al. between the measured neutron yields and the theoretical calculations based on the primary breakup reaction alone cannot be explained by the inclusion of secondary processes. The possible reasons for the observed discrepancy are discussed. The calculations were extended up to Ep = 100 MeV. The conclusion drawn by Bowman et al. regarding the energy cost per neutron at Ep = 100 MeV by extrapolating the empirical function fitted to the experimental data measured up to 17 MeV is not borne out by the present calculations.
