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 statistical analysis of collision cascades caused by 1000 randomly directed energetic primary knock-on atoms (PKAs) using molecular dynamics (MD) simulations in crystal Fe(90%)Cr(10%) is presented. An Fe atom is chosen as the PKA in the energy range 0.1 to 5 keV. The standard deviation of the number of Frenkel pairs created during the collision cascade and range of the PKAs is presented. It is shown that the PKAs must be launched in ∼100 randomly chosen directions for the standard deviation to reach a steady value. For PKA energies 1 keV, 35 of secondary recoils have greater displacement than the PKAs. The results from the MD simulations for the number of displaced atoms are compared with those from the Norgett, Robinson, and Torrens model and other MD simulations of cascade damage in FeCr alloys.
