Temporal gamma-ray spectrometry to quantify relative fissile material content

Creator:: Williford, Russell S.
Abstract:: A new method for delayed gamma-ray spectrometry to quantify the relative content of fissile material is developed and demonstrated to support international efforts in bolstering non-destructive assay capabilities. Previous traditional delayed gamma-ray spectrometry techniques rely upon nuclear data that often carry very high uncertainty. The new method removes the requirement...

Research reactor coolant monitoring using automated gamma ray spectrometry

Creator:: TenBrook, Warren Kermit
Abstract:: An integrated sampling and gamma ray spectrometry system has been developed for analysis of TRIGA reactor primary cooling water. A microcomputer controls pumps and valves using BASIC and assembly language programs to pump 300 ml liquid samples into a reference geometry surrounding a Ge(Li) detector. Gamma ray spectra are acquired...

PAC studies of indium doped cerium oxide

Creator:: Shank, Karl
Abstract:: Perturbed Angular Correlation Spectroscopy (PAC) is a highly sensitive local probe technique well suited for studying defect characteristics of solids. This technique is applied to the problem of studying the solubility of indium in cerium oxide. Through the measurement of samples with differing levels in indium doping, the solubility of...

Applications of beta spectroscopy

Creator:: Pratt, David Sheldon
Abstract:: Two applications of beta spectrometry using active gamma-ray discrimination are described. The beta spectra of smears taken at a nuclear power plant at the end of a 300 day shutdown were characterized. The average beta energy at "contact" (1.5 cm) was between 450 and 550 keV for locations influenced by...

Gamma- and beta-ray spectroscopy studies of the radioactive decay of Mn-51 to Cr-51

Creator:: Glibert, Kenneth Malcolm
Abstract:: The decay scheme of Mn⁵¹ has been investigated using gamma-ray and beta-ray scintillation spectrometers and a fast coincidence spectrometer. A half-life value of 46.5 ± 0.2 minutes was determined for Mn⁵¹ which decays predominantly to the ground state of Cr⁵¹ by the emission of positons with an experimentally measured end-point...

Evaluation of ²³⁵U and ²³⁸U Fast Fission Product Yields from Godiva-IV Burst Irradiation via Gamma Detection

Creator:: Tamashiro, Aaron S.
Abstract:: During the past few decades, the U.S. Department of Energy (DOE) has made significant investments to improve nuclear data libraries, as the quality of this data impacts nearly all analyses of nuclear systems. Nuclear fission product yields are one component of these libraries, and are important for the analysis of...

Special Nuclear Material Analysis Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: Following thermal neutron induced fission, supervised machine learning and temporal gamma-ray spectroscopy methods were used to identify differences in the delayed gamma-ray spectra of Pu-239 and U-235. The temporal gamma-ray spectroscopy method takes advantage of the time-dependent decay of fission products. Employing Spearman's rank-order correlation coefficient and without prior knowledge...
