Temperature measurement on zircaloy clad fuel pins during high temperature excursions

Creators

Description

A program was undertaken to develop a fuel pin clad thermocouple installation and to qualify it for use in PWR-type safety tests. Owing to metallurgical incompatibility between common thermocouple materials and the zircaloy cladding used on the fuel pins, severe restrictions are made on thermocouple attachments. Standard crushable magnesium oxide insulators and chromel/alumel or platinum-10% rhodium/platinum thermoelements were selected for use in these thermocouples. The thermocouples can be laser welded to the fuel pin cladding in such a manner as to provide temperature measurement data through many thousands of hours of reactor operation and through many high temperature cycles
