The water of crystallization of a ceramic material, kaolinite, is used as a standard for calibrating equipment used for measuring the amount of hydrogen in a nuclear fuel pellet. A kaolinite is heated to a temperature sufficient to drive out the water of crystallization in the kaolinite which is a precisely known amount and the amount is measured. Comparison of to the equipment readout with the known values determines the accuracy of equipment calibration. A nuclear fuel pellet is placed in the equipment and exposed to a temperature suffcent to drive off moisture therein after the equipment has been accurately calibrated. The hydrogen content is then measured to provide an accurate indication of total hydrogen content in the pellet. |
