Title:
HEATING ROD FOR CRITICAL HEAT FLUX TEST
Document Type and Number:
WIPO Patent Application WO/2017/016136
Kind Code:
A1
Abstract:
A heating rod for a critical heat flux test comprises a nickel rod, a heating pipe, a nickel pipe, a copper pipe, a ceramic member, copper pieces and a thermocouple. The heating pipe, nickel pipe and copper pipe are connected sequentially in series with sealed and fixed connections, and form a rod body having a hollow structure. The nickel rod is connected to an external upper energized device, and the copper pipe is connected to an external lower energized device. The ceramic member is attached to an inner wall of the rod body and surround the same to form a thermal cavity. The copper pieces are uniformly and horizontally disposed in the thermal cavity and located in the heating pipe. The thermocouple is suspended in the thermal cavity and is fixed by the copper pieces. The present invention provides a high heating temperature, high heat flux and compact structure to meet the requirements of a critical heat flux test, and measures and outputs a temperature parameter by the thermocouple in real-time, such that heat release of a nuclear fuel is accurately simulated, and critical heat flux testing requirements are effectively met. Furthermore, a critical heat flux of a nuclear fuel rod in different operating conditions can be measured to support research and development of a novel nuclear fuel component.
