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...

Fabrication and Closure Development of Nuclear Waste Containers for Storage at the Yucca Mountain, Nevada Repository
U.S. Congress and the President have determined that the Yucca Mountain site in Nevada is to be characterized to determine its suitability for construction of the first U.S. high-level...

Effects of Water Composition on the Dissolution Rate of UO2 Under Oxidizing Conditions
Dissolution rates were measured on crushed unirradiated UO2 fuel pellet samples under oxidizing conditions using a flow-through testing method. Water...

An Astronaut Positioning System for Space Station Assembly and Maintenance Support
Large space structures require special systems to support assembly, operations, and maintenance. These systems must be designed to support many tasks throughout the life of the space facility....
