Diffusion of selected radionuclides through Hanford Trench 8 soil material

Creator:: Schwab, Kristen E.
Abstract:: Shallow land burial in vadose zone sediment at the Hanford Site in Washington is being considered for the disposal of Category 3 low-level waste. A series of column experiments were conducted to evaluate and model the performance of the soil surrounding the trench encasement material for iodine-129 and technetium-99 by...

A thermal hydraulics analysis of a molybdenum production element for implementation in TRIGA reactors

Creator:: Byfield, Patrick
Abstract:: The metastable isotope of technetium-99 (Tc-99m) is an important diagnostic tool used in the field of nuclear medicine due to the isotope's 6.0 hour half-life, 140.5 keV γ-decay mechanism, and multiple oxidation states [1,2]. Approximately 70% of the world’s nuclear medicine procedures involve the use of Tc-99m [3]. The conventional...

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...

Feasibility study on a soluble boron-free small modular reactor

Creator:: Mart, Justin R.
Abstract:: The elimination of soluble boron creates several advantages for Small Modular Reactor (SMR) operation. Most of these advantages are realized through significant core simplification (removal of pipes, pumping, and purification systems), the removal of the corrosive effects of soluble boron, and from improved safety effects. However, removing soluble boron creates...

Design, fabrication, and characterization of the laser-imaged natural circulation (LINC) facility

Creator:: Goodrich, Sam S.
Abstract:: Currently there is a great amount of interest in the phenomena of natural circulation as a cooling mechanism for normal operation as well as emergency conditions in nuclear reactors and spent fuel pools. In order to better understand this phenomena for the specific geometry of vertical, heated rods in water,...

Neutron radiography and tomography : determining and optimizing resolution of neutron sensitive multi channel plate detectors

Creator:: Williams, Walter James
Abstract:: The objective of this work was to determine and optimize the resolution of a neutron sensitive Multi-Channel Plate (MCP) detector in order to determine its capabilities in radiography and tomography. The Oregon State University, Neutron Radiography Facility added an MCP Detector in 2012 in order to analyze these capabilities. The...

Site specific reference person parameters and derived concentration standards for the Savannah River site

Creator:: Stone, Daniel K.
Abstract:: The U.S. Department of Energy (DOE) Order 458.1 states that the compliance with the DOE annual dose limit of 1 mSv (100 mrem) to a member of the public may be demonstrated by calculating dose to the maximally exposed individual (MEI) or to a representative person. Historically, the MEI concept...

Dose-effects relationships in non-human biota : development of field sampling, dosimetric and analytic techniques through a case study of the aquatic snail Campeloma decisum at Chalk River Laboratories

Creator:: Ruedig, Elizabeth B.
Abstract:: In the last decade regulatory bodies have begun to implement standards to protect populations of non-human biota (NHB) from the consequences of radiation exposure. This is a departure from previous regulatory frameworks which were concerned only with protecting man. The implementation of these new standards has started an ongoing discussion...

Scaling study of the depressurized conduction cooldown event in the high temperature test facility using RELAP5-3D/ATHENA

Creator:: Aldridge, Robert J.
Abstract:: In 2008, the Department of Energy (DOE) and Nuclear Regulatory Commission (NCR) decided that the Next Generation Nuclear Plant (NGNP) would be the Very High Temperature Reactor (VHTR). In support of the licensing and validation effort of the VHTR, Oregon State University was tasked with designing, building, and operating a...

Design and analysis of radiation shielding eyewear

Creator:: Spackman, David A.
Abstract:: The recent reductions to the international dose limit recommendations for the lens of the eye have renewed interest in radiation protection strategies in interventional fluoroscopy, where eye-lens radiation exposure occurs frequently. Radiationshielding eyewear can significantly reduce lens dose in these scenarios, but accurate protection factors are elusive because they depend...
