The MInes NEutron Radiography (MINER) facility provides students and researchers at the Colorado School of Mines with the capability to perform neutron imaging at the Geological Survey TRIGA Reactor (GSTR). The current beamline consists of a 1.5 inch innerdiameter aluminum pipe routed from the reactor up to an experiment station in the reactor bay. There are several limitations associated with ...

The hydride distribution in a cracked Zircaloy cladding tube has been investigated by neutron radiography, Scanning Electron Microscopy (SEM) and Hydrogen measurements. The crack occurred during handling in the spent fuel pool. Back Scattered Electron images showed some unexpected contrasts in zones with high hydrogen concentrations near cracks. This phase has been studied by SEM and EPMA. Afte...

We describe features of the HADES radiographic simulation code. We begin with a discussion of why it is useful to simulate transmission radiography. The capabilities of HADES are described, followed by an application of HADES to a dynamic experiment recently performed at the Los Alamos Neutron Science Center. We describe quantitative comparisons between experimental data and HADES simulations u...

A novel set-up for monitoring the gas diffusion process in polymers has been developed. This is based on performing neutron radiography and tomography of polymeric materials under high pressures gas. Information about absorption kinetics supercritical CO2 was obtained. Additionally, solubility, diffusivity, macroscopic changes dimensions samples can be in-situ obtained through developed measure...

Due to the large thermal neutron absorption cross section of 10B, B4C-Al composites have been used as neutron absorbing materials in nuclear industries, which can offer not only good neutron shielding performance but also excellent mechanical properties. The distribution of B4C particles affects the mechanical performance and efficiency of the thermal neutron absorption of the composite materia...
