Abstract

A dry-inert atmosphere drybox system for handling sodium metal without any contamination of oxygen and water in air has been designed and constructed. This system maintains a working atmosphere of argon containing less than 1 ppm each of oxygen and water. It consists of a stainless steel drybox which has three pairs of butyl rubber gloves and an atmosphere purifier, using NaK as the purifying medium. A spiral blower circulates the gas from the drybox through the purifier and back to the drybox at a flow rate of approximately 1 m3/min. A subsystem of pressureactivated switches and solenoid valves maintains the drybox at a slightly positive pressure. Surface of sodium metal in the system remains bright for a period of up to 8 hours.
