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.

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.

To improve the accuracy of the after-shot plasma equilibrium reconstruction on Tore Supra, the previous EFIT code, which utilizes only magnetic measurements as a constraint (we shall call it EFIT-mag in the text), has been modified into EFIT-pol by taking the far infrared polarimeter measurements into account. With a correct choice of the input parameters (mainly for the P' and FF' polynomial orders and for the weights on Faraday angles), the results reconstructed by EFIT-pol are in good agreement with the experimental values deduced from the magnetic measurements as well as with the CRONOS code simulations. In this paper, after a brief description of the EFIT code, the approach used to parameterize EFIT-pol is presented, and the accuracy improvement is shown for a typical shot of Tore Supra, as well as through statistics on a database of 95 shots of different plasma currents and additional powers.
