ABSTRACT:
Zircaloy metal is utilized to form the heat generating core and internal lining of a high strength pressure barrier for a gamma thermometer. The internal lining which is cross-sectionally smaller than the core, forms a hydrogen gas barrier to prevent deterioration of the low thermal conductivity of the thermal resistance region in the thermometer.
