Production of monodisperse cerium oxide microspheres with diameters near 100 µm by internal-gelation sol–gel methods

Autor: Jeffrey A. Katalenich, Bruce D. Pierson, Brian B. Kitchen

Publikováno v: Journal of Sol-Gel Science and Technology. 86:329-342

Internal-gelation sol–gel methods have used a variety of sphere-forming methods in the past to produce metal oxide microspheres, but typically with poor control over the size uniformity at diameters near 100 µm. This work describes efforts to make

Fission Product Yields from 232Th, 238U, and 235U Using 14 MeV Neutrons

Autor: Marek Flaska, Bruce D. Pierson, L.R. Greenwood, Sara A. Pozzi

Publikováno v: Nuclear Data Sheets. 139:171-189

Neutron-induced fission yield studies using deuterium-tritium fusion-produced 14 MeV neutrons have not yet directly measured fission yields from fission products with half-lives on the order of seconds (far from the line of nuclear stability). Fundam

This work expands the availability of energy-resolved short-lived cumulative fission product yields for 235,238,233U, 239Pu, and 237Np subjected to a 2$ pulse in the Washington State University TRIGA reactor. A boron carbide capsule tailored the neut

Benchmarking the repeatability of a pneumatic cyclic neutron activation analysis facility using 16 O(n,p) 16 N for nuclear forensics

Autor: Henry C. Griffin, Jeff Katalenich, Bruce D. Pierson, Brian B. Kitchen, Sara A. Pozzi, Marek Flaska

Publikováno v: Applied Radiation and Isotopes. 96:20-26

A target was prepared for cyclic neutron activation analysis by heat sealing lithium-carbonate in polyethylene. The target was cyclically irradiated 50 times using a Thermo-Scientific accelerator based deuterium–tritium fusion neutron generator. Du

Short-lived fission product measurements from >0.1 MeV neutron-induced fission using boron carbide

Autor: Bruce D. Pierson, Erin C. Finn, Rosara F. Kephart, Lawrence R. Greenwood, Lori A. Metz, Judah I. Friese, Jeremy D. Kephart

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 293:267-272

A boron carbide shield was designed, custom fabricated, and used to create a fast fission energy neutron spectrum. The fissionable isotopes 233, 235, 238U, 237Np, and 239Pu were separately placed inside of this shield and irradiated under pulsed cond
