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 integral transport equation is solved in square unit cells by assuming the existence of a fundamental mode. The equations governing the Bn method are given without making the small buckling approximation. First, the angular flux is factorized into two parts: a periodic microscopic fine-structure flux and a macroscopic form with no angular dependence. The macroscopic form only depends on a buckling vector with a given orientation. The critical buckling norm, along with the corresponding fine-structure flux, is obtained using collision probability calculations that are repeated until criticality is achieved. The procedure allows the periodic or reflective boundary conditions of the unit cell to be taken into account using closed-form contributions obtained from the cyclic tracking technique. Numerical results are presented for one-group heterogeneous cell problems with isotropic and linearly anisotropic scattering kernels, some of which include void regions.
