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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

In fusion technology, functional scales are required for various application fields like first wall tungsten coating, anti-corrosion or tritium permeation barriers, and brazing layers in joining technology. Established processes for layer deposition exhibit several kinds of drawbacks ranging from difficulty controlling layer thickness, inhomogeneity of coatings, application limits because of geometrical reasons, or critical thermal loading. Inherently, electrochemical plating technology does not exhibit these critical features. Growing of galvanic layers depends on the transported charge and thus can easily be controlled by current flow and/or deposition time. The main part of this development work was focused on voltammetric analyses to assist the deposition of transition metals on refractory metal surfaces, e.g., tungsten and Eurofer steel, and to deliver boundary conditions for electrolytes. Typical elements that can be used in joining may range from Ti, V by Ni, Fe up to Pd, and Cu. However, a direct joining of tungsten onto Eurofer steel by copper is metallurgically impossible due to missing miscibility of copper with tungsten. Thus, interlayers with an active functionality are required, which interact with both bulk components and filler to obtain a sound braze joint brazing. For both W-W and W-Eurofer joints, demonstrators were successfully fabricated and analyzed by metallurgical and physical methods.
