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 promising fuel concept for fast breeder reactor applications is sphere-pac mixed carbide fuel. To support this development, it is necessary to devise analytical methods to assess and predict the behavior of fuel pins under irradiation conditions. This Note describes the modeling of the thermal aspect of this behavior. As a first step in treating a sphere-pac mixed carbide fuel pin, models for various physical phenomena have been developed and integrated to give the overall fuel pin response. Included are descriptions for the thermal conductivity of the packed particle bed in its initial configuration and during restructuring, the sintering of fuel spheres leading to the restructuring within the pin, the temperature distribution, grain growth and porosity redistribution, gas release and free swelling, and the effect of the gas in the free volume of the pin. The models describing the various thermal components were incorporated into the computer program SPECKLE-I. In the absence of a detailed mechanism analysis, restrictive assumptions were made. While the code is a limited first step in the analysis, results from SPECKLE-I were compared with several pin irradiations. Calculations of gas pressure and composition, fractional gas release, and the extent of initial-stage restructuring within the pin were compared to measurements. Initial results generally agree to within 20% or better for the parameters investigated.
