Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The purpose of the International Fusion Materials Irradiation Facility (IFMIF) is to provide irradiation conditions of a typical deuterium-tritium (D-T) fusion reactor for small material samples, but with higher irradiation levels. An extensive code and data development has been performed, allowing a comprehensive neutronic analysis of the high-flux test volume. New data evaluations for neutron interactions and responses at high energies (20 to 50 MeV) were performed and processed, and a Monte Carlo neutron source model for the Li(d,xn) reaction was developed for use with the MCNP neutron transport code.The neutron flux density was found to be >1014 ncm-2s-1 throughout the anticipated high-flux test volume with a high-energy fraction (>14 MeV) of ~20%. The available test volume with >20 dpa/full-power year in iron was found to be 550 ± 180 cm3. This uncertainty is due almost entirely to the uncertainty in the total neutron yield. Hydrogen and helium production rates were calculated and a helium/dpa ratio between 10 and 12 appm/dpa was found, which is similar to that found in a D-T fusion reactor. IFMIF was found to provide an adequate environment for the simulation of D-T fusion reactors, but more work is required to extend and improve the current data and tools.
