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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

This paper reports Japanese activities on tungsten material development and the basic studies on plasma and tungsten interactions. Effects of helium ion irradiation on embrittlement and bubble formation of various tungsten materials have been intensively investigated in Japan. Details of the helium bubble formation mechanism, its effects on surface morphology ,and the impacts on dust formation are presented. Fine-grained and TiC fine-particles dispersed tungsten are being developed to increase the resistance of the material to degradation in the fusion reactor environment. Microstructures and specific features amenable to fusion environments are presented. The experimental results on repetitive heat pulses on surface roughening and cracking are shown. The repetitive heat pulse effects are very serious and further studies are needed. Important issues of tungsten material development for DEMO and commercial devices will be discussed.
