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.

In ITER, reflection of photons on vacuum vessel will make parasitic signals (stray light) for optical diagnostics. In this study, to estimate and mitigate the effect of the stray light in ITER in a systematic manner, a ray transfer matrix was constructed based on ray tracing calculations for a divertor impurity monitor and charge-exchange recombination spectroscopy (CXRS). It is shown that the allocation of the sources around the strike point and the X-point, where the emission is strong, is important for the model used to build the transfer matrix to effectively mitigate the stray light. The origin of the stray light for the core CXRS is investigated, and a case study to subtract the stray light is shown.
