Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Fukiushima Daiichi: 10 years on
The Fukushima Daiichi site before the accident. All images are provided courtesy of TEPCO unless noted otherwise.
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.

Measurements of tritium concentration on the surface and in depth of various samples of constructional materials employed in nuclear power engineering have been made by making use of a magnetic microscope and a magnetic imager. -radiation images of large (up to 0.5 m) radioactive contaminated surfaces in a nonuniform magnetic field were obtained. The magnetic field uniformly increasing in the direction from the observable surface to the recording screen was used. The principal conditions of identical transfer of the image and its reduction coefficient were determined depending on the ratio of the magnetic fields on the sample surface and the screen. The experiments were carried out in vacuum conditions. The magnetic field was produced with a cylindrical rod of a magnetic material and in the screen area it was 0.5 T. Formation, transport and detection of images were fulfilled in a wide range of their reduction ratio (1-1/40).
