3D-printed tool at SRS makes quicker work of tank waste sampling
A 3D-printed tool has been developed at the Department of Energy’s Savannah River Site in South Carolina that can eliminate months from the job of radioactive tank waste sampling.

Energy loss by fission fragments in nitrogen gas was studied by means of a pulse technique that measured luminescence excited by a low-intensity Cf252 spontaneous fission source. A novel kinetic analysis of competing emission and quenching reactions was developed that gives the power law dependency of energy loss by the fragments in a luminescing gas from the pressure at which maximum luminosity is observed. For nitrogen, the relationship E = E0(1−f)1.70 ± 0.07 is valid for 0.4 E0 < E < E0. The term E is used for the kinetic energy of a fission fragment of initial energy E0 that has traveled a fraction f of its total range.
