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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

The aim of the work is to develop the fabrication technology of a small curved tungsten (W) macro-brush–type geometry using a vacuum brazing technique. Taking the design concept of the ITER divertor dome, the present mock-up has scaled down more than ten times in size. A feasibility study of the curved brazing was done, and design and fabrication of the special fixture for the curved profile brazing were carried out. The vacuum brazing technique was used to develop the joining of tungsten tiles in the curved profile of a CuCrZr block (heat sink) using silver-free brazing alloy (NiCuMn-37) with a specially designed custom-made fixture (Type 304 stainless steel). Nondestructive testing, particularly the ultrasonic immersion technique, was incorporated to inspect the quality of the brazed joint in the mock-up. The hardness value (HV) measured on the copper alloy was found to degrade from 143 to 46 HV (before and after brazing). The results of the experimental activity and methodology adopted to fabricate the small-sized trial W mock-up are presented and discussed in the paper.
