Development of a Welding Process for End Closures on NPR and KER Fuel Element

Description: With the development of the zircaloy-2 clad uranium fuel element, it was necessary to develop a method of closing the end of the element after the extruded tubes were cut to the desired length. Regardless of the ultimate design of the closure, a satisfactory zircaloy-2 fusion welding technique had to be worked out. The first fully successful welding was performed with electron beam welding in a vacuum chamber. To make satisfactory welds, the electron beam welding involved time and equipment, pl… more

Utilization of the Surface Tension of Liquid Metals in Making High-Vacuum Seals

Description: Abstract: "The free energy (surface tension) of a liquid film can withstand atmospheric pressure across a maximum theoretical gap of 10-(-3) cm between solids if the liquid wets and bridges the sides of the gap continuously. The eutectic alloy of Ga, lm and Sm is used for this purpose. This alloy is molten at room temperature with surface tension > 500 dynes/cm, vapor pressure < 10-(-8) cm at 500 C and excellent wetting properties. This alloy can be utilized in valves, motion seals, flanged joi… more

Fluidtight Seal for a Container

Description: A fluidtight seal for a container is formed by abutting a metal ring with a step machined in a convexo-concave container closure device and inserting this assembly into an open end of the container. Under compressive force, the closure device deforms causing the metal ring to pivot about the step on the closure device and interact with symmetrically tapered inner walls of the container to form a fluidtight seal between the container and the closure device. The compressive force is then withdraw… more

Military Base Closures: A Historical Review from 1988 to 1995

Description: The United States has experienced difficulty in closing military bases to match the requirements of downsized forces with changed composition. During the decade of the 1980s, major military base closures were seriously hampered by procedural requirements established by Congress, to the point that none occurred. The mismatch between real estate assets and defense requirements grew with the military downsizing that began late in the Reagan Administration and continued under Presidents George H. W… more

Base Realignment and Closure (BRAC): Property Transfer and Disposal

Description: The Defense Base Realignment and Closure Act of 1990 and the Federal Property and Administrative Services Act of 1949 provide the basic framework for the transfer and disposal of military installations closed during the base realignment and closure (BRAC) process. This report provides an overview of the various authorities available under the current law and describes the planning process for the redevelopment of BRAC properties.
