When your test capsule is the test: ORNL’s 3D-printed rabbit
Oak Ridge National Laboratory has, for the first time, designed, printed, and irradiated a specimen capsule—or rabbit capsule—for use in its High Flux Isotope Reactor (HFIR), the Department of Energy announced on January 15.

The fission cross-section ratio 240Pu:235U has been measured as a function of neutron energy from 5 to 300 keV using ionization fission chambers, the time-of-flight technique, and the threshold cross-section method at the Lawrence Livermore National Laboratory's 100-MeV electron linear accelerator. Distinct structure is observed in the cross-section ratio over this subthreshold energy range.
