ITA to work with IAEA on advance geologic repository knowledge
The International Tunnelling and Underground Space Association (ITA), a nongovernmental organization made up of 81 member states working to advance the safe, beneficial use of subsurface spaces, is working with the International Atomic Energy Agency to support the advancement of geologic disposal facilities for high-level radioactive waste.

Rate coefficients and normalized differential scattering rate distributions for (n-n), (n-d), (n-t), and (n-6Li) elastic reactions for radially translating Maxwellian-distributed targets are examined for energy and temperature ranges related to fusion energies. For these reactions, both asymptotically constant cross sections and cross sections decaying inversely as the relative speed are treated. For the (n-d), (n,t), and (n-6Li) cases, actual multigroup cross sections are employed in the energy range from 0 to 17 MeV, while the (n-n) interaction is treated in the hard sphere limit. Some results for various incident and final neutron energies at a target temperature of 2 MeV are listed, and conclusions from an extensive numerical analysis are given.
