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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Hydrogen isotope retention and its removal in/from a plasma-facing wall and structural materials have been recognized as key issues for fusion reactor from the viewpoints of operational safety and environmental preservation. Baking and/or a glow discharge are possible effective methods to remove hydrogen isotopes from materials. To investigate the absorption and desorption characteristics of hydrogen isotopes in structural materials, a glow discharge apparatus with twin chambers (Glow-1, 2) made with stainless steel was provided. The sample tip can be moved between the Glow-1 chamber and Glow-2 chamber without exposing it to the air. The controlled infrared (IR) heating device was installed in the Glow-1 chamber to heat the sample tip. Results of absorption and desorption by glow discharge, and the thermal desorption by IR heating are analyzed. No oxides of hydrogen isotopes were observed in these experiments. Most gases are retained near the solid surface and are desorbed at a low temperature below 150 °C. The activation energy was estimated to be about 50 kJ/mol.
