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.

A pilot rig for a preparative gas chromatograph is described. In order to increase the volume of the samples to be separated different separation columns were investigated. The pilot plant is designed as to operate also with two columns at the same time. To recover the separated H isotopes the pilot rig was equipped with three uranium getters which can be automatically switched to the separation columns by electropneumatic valves. These valves are actuated in response to a detector signal. The maximum sample volume achieved with one separation column is 600 ml (STP) of a three-component mixture (H2, HD and D2) with a purity of 98.5 - 98.7% and even 1000 ml (same mixture) with a 91% purity with respect to the components H2/HD.
