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.

The value of the effective delayed neutron fraction has been measured for a compact loading of the BSR-I by the boron-substitution technique. The value obtained was 0.0080 ± 0.0002. By adopting the value of the true delayed neutron fraction. β = 0.0064 ± 0.0002, measured by Keepin et al., the ratio of the effective delayed-neutron fraction to the true delayed-neutron fraction is found to be 1.25 ± 0.05. When this quantity was computed by a three-group PDQ-code calculation, the result was 1.25, an agreement which suggests the validity of the computational method.
