Description

The oxygen concentration influences kinetics of the zirconium hydriding process. The method presented in this paper is applied for an accurate determination of the oxygen in zirconium and zirconium alloys. The sample is melted at high temperature. During the melting process, the oxygen is continuously released from the investigated material. O2 reacts with the hot crucible producing CO, which is converted to CO2 in a catalyst furnace. The CO2 is detected by a IR-cell. The signal from the cell is converted by an electronic unit, and the result is shown, directly as 'O' ppm. Using an ELTRA OH 900 infrared analyzer, measurements of O content have been made in zirconium sponge and U-Zr-Er alloys, the main materials used in TRIGA fuel fabrication. (author)
