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.

Tungsten (W) is a promising candidate as for the plasma-facing material in future nuclear fusion reactors. The interstitial helium (He) atoms in bulk tungsten will degrade seriously the mechanical properties of tungsten. In the present paper the effect of interstitial He atoms on the production and evolution of defects in irradiated tungsten has been investigated using molecular dynamics (MD) simulations. Under the conditions of different primary-knocked atom (PKA) energies and irradiation temperatures, it is found that the interstitial He atoms increase the generation of Frenkel pairs, and this tendency can be greatly promoted by increasing the PKA energy and irradiation temperature. The interstitial He atoms can also increase the displacement cascade efficiency and impact greatly on the structure of radiation-induced defects in tungsten.
