Grass Reference Measurements in Italy
In this paper, the description and the use of drainage and weighing lysimeters installed in different Italian locations are reported together with the results of the researches about the...

Crop Canopy Models for Estimating Evapotranspiration from Row Planted Field
To evaluate the consumptive use efficiency of irrigated water, it is useful to estimate the soil surface evaporation component separately from the transpiration component. Interception...

Concentration Measurements in Dense Leachate Plumes Using a Gamma Radiation System
An automated, nonintrusive technique is discussed that determines salt concentrations in dense leachate plumes. The dense plumes were introduced from a line source into a relatively narrow...

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...

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...

Incorporation of Reprocessing Raffinates and High Level Solids in Cement
Reprocessing highly enriched uranium fuel from UKAEA Materials Testing Reactors produces highly active aqueous raffinate. This is currently stored. The UK strategy is for raffinate immobilisation,...

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...

Method for Determining the Fuel Contribution to the Source Term in Trasnport Casks
A comprehensive source term characterization methodology has been developed for the determination of the fuel contribution to the potentially releasable radioactivity in spent fuel shipping...

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...

Lunar Base Elements Designed for Robotic Operations
Equipment concepts developed for a study of robotic lunar surface operations are presented. The concepts were evolved together with a consistent robotic buildup and operations scenario;...

Space-Based Control of the Climate
The expected global greenhouse warming of 2 °C may be reversed by a space-based screen that intercepts 3% of the incident solar radiation. Space-based devices may also mitigate the ozone/UV...

Implications of the New Radiation Exposure Limits on Space Station Freedom Crews
Spaceflight unavoidably increases the exposure of astronauts to natural ionizing radiation. Any increase in radiation exposure increases the risk of contracting cancer or inducing genetic...

Space Power Systems—Radiation: Energy Conversion
Pair production is a way to change a photon, a gamma particle, into matter or energy. It is found that if a photon of energy greater than 1.02 MeV strikes a foil containing a large number...

Mission to Planet Earth: The Quest to Save the Environment
The Mission to Planet Earth is a program designed to look at the earth as an integrated system. It is an internationally supported project. It was conceived because the current methods...
