Helium generation in fusion reactor materials
Abstract
An analysis was made of the multiple-step helium production mechanism discovered in iron following long term mixed-spectrum reactor exposure, the measurement of a large number of samples irradiated in fast-neutron environments for cross section determinations, the initial mapping of the neutron fluence distribution for a high fluence T(d,n) irradiation experiment, the initial measurements of helium production in materials irradiated by 10-MeV neutrons, and the initiation of a joint experiment with ANL to measure the spectrum-integrated Be(n,2n) cross section at lower neutron energies.
