Abstract

Thermal decomposition of sodium hydride and removal of hydrogen under vacuum or flowing argon appears a possible technique for the regeneration of hydride laden LMFBR cold traps. However, little is known about the kinetics of these processes, and this paper describes some measurements of the rate of hydrogen removal from sodium/sodium hydride mixtures by continuous evacuation in the temperature range 260 – 420 °C and by argon purging in the range 293 – 360 °C. Some observations on the kinetics of hydrogen desorption from unsaturated solutions of sodium hydride in liquid sodium at temperatures up to 400 °C are also presented.
