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.

Fukiushima Daiichi: 10 years on

It was a rather normal day back on March 11, 2011, at the Fukushima Daiichi nuclear plant before 2:45 p.m. That was the time when the Great Tohoku Earthquake struck, followed by a massive tsunami that caused three reactor meltdowns and forever changed the nuclear power industry in Japan and worldwide. Now, 10 years later, much has been learned and done to improve nuclear safety, and despite many challenges, significant progress is being made to decontaminate and defuel the extensively damaged Fukushima Daiichi reactor site. This is a summary of what happened, progress to date, current situation, and the outlook for the future there.

In the tandem mirror GAMMA 10, a 500 kW gyrotron was newly equipped in the central-cell ECRH system, following the plug ECRH systems. Then, the transmission system for the central-cell ECRH, including a taper, mirrors and a polarizer, has been designed correspondingly. The guidelines to design the transmission system are to make the beam cross section axisymmetrical on the resonance surface with a high power transmission rate and high heating efficiency. According to the guidelines, mirrors in the launcher systems have been designed with our electromagnetic code. Controlling polarization of the incident microwave is achieved with a polarizer for raising heating efficiency.
