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.

Current fuel assembly designs can achieve burnups that exceed the design burnups for many shipping casks. A proposed solution for this situation is regionalized loading, which involves administratively separating the fuel basket of a shipping cask into two or more regions and loading fuel with different burnup, cooling times, and enrichments into each region. The analysis evaluated how regionalized loading affected spent-fuel shipments.Fuel having a range of burnups and a shipping cask were used in the analysis. The SCALE5 control module SAS2 was used to develop the radiological source terms, and MCNP5 was used to calculate the dose rates associated with the different loading patterns. The analysis indicated that the use of dual-zone loading patterns violated the principles of as-low-as-reasonably-achievable radiation levels. However, the analysis also showed that dual-zone loading patterns reduced the dose rates associated with shipping high-burnup fuel and reduced the time required to ship the fuel. Further analyses were performed to see if a compromise existed.
