ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

With increases in the heating and driving power in EAST, the present SiC-C plasma-facing components (PFCs) will be replaced by W coatings on actively cooled Cu heat sinks in the lower-heat-flux zone (first wall), prepared by vacuum plasma spraying, and by ITER-like W-Cu monoblocks in the higher-heat-flux zone (divertor). These components are provided with thousands of joints that should be assessed to demonstrate their integrity. An ultrasonic method named pulse echo using high-frequency probes and normal incidence of the ultrasonic beam to the joint interface has been developed. For the W-coating PFC, although the existence of porous structure, shrinkage cracks, and delamination in W coating can adversely affect the sensibility of detecting interface defects, the ultrasonic technique is able to detect, locate, and size them in certain conditions; for the W-Cu monoblocks, the ultrasonic technique is also able to detect, locate, and size defects in the W-oxygen-free high conductivity (OFHC) Cu interface, but further detecting and analysis should be carried out for the OFHC Cu-CuCrZr interface based on the preliminary work.
