Apparatus and method for generating hydride rim of zirconium-alloy fuel cladding by generating temperature gradient of tube between inside and outside

摘要

The present invention relates to an apparatus and method for generating a hydride rim of a zirconium alloy cladding. This method is based on a method of simulating the temperature gradient environment of the inner and outer surfaces of the actual spent fuel cladding experienced during operation of a nuclear reactor, and the apparatus for generating a hydride rim of a zirconium alloy cladding according to the present invention includes a main chamber; test chamber; heating heater; temperature measuring thermocouple; cooling fan; control unit; includes.
