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...

Trihalomethane Precursor Removal by Ozone and Ultraviolet Radiation
The research objectives were definition of trihalomethane formation potential (THMFP) reduction in groundwater matrix using ultraviolet radiation (UV) catalyzed ozone oxidation (UV/Ozone)....

Ground Water Treatment System Using UV/H2O2 at Sacramento Army Depot
Ground water beneath the Sacramento Army Depot (SAAD) is being extracted and treated as part of a ground water remediation program. The extraction system is achieving contaminant capture...

Going Where No Man Can Go
After the 1979 accident at Three Mile Island Unit 2 in Harrisburg, Pa., some areas of the reactor plant were too contaminated for workers to survey, much less clean. The article describes...

Tomorrow's Energy Today
If concerns about global warming, acid rain and air pollution continue to mount, replacements for fossil fuels�for a century the dominant power source in the U.S.�will be necessary to...

The Continuing Evolution of a Radioactive Material Transport System
The paper considers the evolution of BNFL's transportation system and those lessons learned and incorporated or being incorporated in the system as it continues to evolve....

Regulatory Considerations for Designing Surface Facilities for Yucca Mountain High-Level Waste Repository
This paper outlines U.S. Nuclear Regulatory Commission's (NRC's) key regulations applicable to U.S. Department of Energy's (DOE's) design...

Recent Results on the Effect of Gamma Radiation on the Durability and Microstructure of DWPF Glass
The effect of gamma radiation on the durability and microstructure of a simulated nuclear waste glass from the Savannah River Site has been carefully investigated. Three large pieces of...

High Level Waste Management at Sellafield
Reprocessing of irradiated nuclear fuel has been carried out at Sellafield since 1952, when reprocessing of fuel from the original UK air-cooled reactors began. In 1964 a second reprocessing...

Interaction of Microwave Radiation with Matter: a Thermodynamic Approach

Experimental Microwave Processing of Lunar Regolith Simulant for the Recovery of Volatiles

Waste Heat Rejection System for a Lunar Oxygen Production Plant

Design and Construction of a Lunar Outpost Assembly Facility

Astronomical Science from a Lunar Base

Ionizing Radiation Environment at the Mars Surface

Incident Solar Flux at Fixed Orientations
Optimal orientations are computed to maximize or minimize the incident solar flux onto surfaces on spacecraft at fixed attitudes. This analysis was motivated by a potential need to optimize...
