Evaluation of Neutron Emission from Vitrified HLW Compositions
Neutron radiological hazards from vitrified HLW are important for handling and transportation - especially if the concept of separate storage of concentrated transuranics is adopted, as...
Treatment of Non Fuel Bearing Scrap
Problems encountered with the processing of irradiated non fuel bearing components (NFBC) during several rod consolidation demonstration programs identified the need to conduct further...
The Effect of Gamma Irradiation on the Volatility and Redox State of Simulated DWPF High-Level Nuclear Waste Glasses
Gamma-induced volatility of simulated DWPF high-level nuclear waste glasses is highly dependent upon the redox state of the glass. For oxidized glasses with an Fe2+/(Fe2+...
Mine Support, Radiation and Ventilation Control with Spray-on Barriers
The use of spray-on liner agents to provide localized excavation support in place of traditional techniques such as shotcrete or bolts-and-screen has been the subject of extensive investigation....
Radiation Balance and Soil Water Evaporation of Bare Pullman Clay Loam Soil
Radiation and energy balance components and soil water evaporation were measured for a bare Pullman clay loam soil at Bushland, TX during the 1992 spring and summer as the soil dried following...
Atmospheric Radiation Balance Over Alfalfa
An experiment was carried out in an alfalfa field in Logan, Utah, U.S.A., during 8-12 September 1992, to evaluate methods and expected accuracy of continuous radiation balance component...
Growing Season Evapotranspiration and Crop Coefficient
The Bowen ratio-energy balance (BREB) method was used to continuously estimate 20-minute actual evapotranspiration (ETa) in the middle of a 36-ha...
Stratification Models Sensitivity to Solar Radiation Data
A one-dimensional water quality model (WESTEX model) for simulation of thermal stratification is used to test the performance of such models related to hydrometeorological input data....
Constructing Radiation Shields with Textiles for Lunar Applications
The problem of radiation shielding on the lunar surface is significant. The mass required for adequate shielding is enormous and economics would dictate the use of lunar soil for this...
Ropeway Material Handling Systems for Lunar Mining Sites
The establishment of permanent lunar sites will be a requirement for future space explorations during early missions into space as well as long term. During all stages it will be necessary...
Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...
Metallized Microballoon EMI Shielding Materials
The number of applications requiring shielding against electro-magnetic interference (EMI) is growing. Materials that are lightweight, and formable need to be developed for shielding against...
Radiation Energy Treatment of Water, Wastewater and Sludge
A State-of-the-Art Report
Since ionizing radiation is one of the more technologically advanced forms of energy available to society, it has been applied to a great many activities such as: the sterilization of...
Regulatory Issues Impacting the U.S. High-Level Radioactive Waste Management Program
This paper addresses current key regulatory issues impacting the U.S. high-level radioactive waste management program. The following issues pertain to the licensing of a geologic repository:...
Effect of Ionizing Radiation on the Waste Package Environment
The radiolytic production of nitrogen oxides, nitrogen acids and ammonia are discussed in relation to the expected environment in a high-level waste repository that may be constructed...
An Approach to Assessing the Impacts of Incident-Free Air and Highway Transportation of Radioactive Materials
Annual radiation doses and risks were calculated for shipments of radioactive materials both in passenger aircraft and on highways, under accident-free and incident-free conditions, i.e.,...
Time-Domain Transmitting Boundary Condition in Fluid-Structure Interaction Studies
One of the major difficulties in the nonlinear analyses of fluid-structure interactions has been the lack of exact expressions for the transmitting boundary in the time domain. Researchers...
Vacations in the Sun: Can They Survive the Effects of Global Ozone Depletion?
The impact of elevated levels of ultraviolet on human health is already being reported. With tourism slated to become the economic mainstay in many tropical countries, there is the very...
UV Disinfection of Wastewater: A Pilot-Scale Study of Performance
A pilot-scale study of UV disinfection under field conditions was conducted. Inactivation and photoreactivation was well correlated with UV dose. Standards of 100 coliform/100 mL were...
