A comparative evaluation of the health risks from minor actinide fission products

Creator:: Wilmot, Aaron
Abstract:: In consideration of the potential use of minor actinides in nuclear fuel, the fission products of several minor actinides (²³⁷Np, ²⁴¹Am, ²⁴²[superscript m]Am, ²⁴³Cm, ²⁴⁴Cm, ²⁴⁵Cm, and ²⁴⁶Cm) were evaluated and compared to the fission products of ²³⁵U. Available data from the Evaluated Nuclear Data File and the Nuclear Database...

Primary fission fragment yields and prompt-neutron emissions for after-heat analysis

Creator:: Liaw, Jye Ren
Abstract:: Independent fission product yields are primary input nuclear data in the evaluation of nuclear reactor after-heat when using a nuclide-decay summation method. The error in yield values is one of the major causes of uncertainty of this calculation. Since only a small fraction of the fission product yields has been...

An analysis of fission product gamma spectra : the use of nuclear systematics to estimate gamma spectra

Creator:: Holter, Gene David
Abstract:: The gamma contribution to reactor afterheat depends on gamma energy since high-energy commas are more likely to escape from tilt. fuel. The objective of this work is to investigate the gamma-energy spectrum of a pure U-235 fission reactor. Fission-product nuclides are first listed in order' of importance as contributors to...

The contribution of fission product decay energy uncertainty to uncertainty in calculated reactor decay power

Creator:: Baker, Steven M.
Abstract:: The uncertainty in decay energy for those fission products which contribute significantly to reactor shutdown power was evaluated. The methodology used assigned significantly larger uncertainties for data which were theoretically predicted than it did for experimentally determined data. The uncertainty was modeled as an increasing function of distance from beta...

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...

Characterization of fission product transport in a gen. IV gas-cooled fast reactor plant utilizing vented fuel

Creator:: Deason, Wesley
Abstract:: Fission product transport in a Gen. IV Gas-Cooled Fast Reactor Plant utilizing vented fuel has been characterized using analytical and computational methods. The goal was to increase current understanding of fission product transport in helium-cooled GFRs using vented fuel and to provide a toolset for determining issues which may arise...

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...
