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.

Recent experimental results of power and particle control in JT-60U with W-shaped pumped divertor are presented. Backflow of carbon impurities towards x point is decreased by the dome as well as by the gas puff from the main plasma. Heat load on divertor plates is reduced by the detached plasma at high density and radiative plasma by neon seeding. Effective helium exhaust is demonstrated for helium-beam-injected plasmas. Results of high-confinement experiments are also shown. Strongly heated ELMy H-mode plasmas are sustained during 9 s without increasing the impurity contamination. High QDTeq ~ 1 is obtained in the low Ip regime of the reversed shear plasmas. Progress in the negative-ion-based neutral beam injection experiments is finally introduced
