Steam-Cooled Fast Breeder Power Reactors Parametric Design Studies
- Battelle Pacific Northwest Labs., Richland, WA (United States)
The nuclear survey was based on a set of nine combinations of steam inventory and core material volume fractions, designated as cases 0A through 2C. Figure 1 shows the characteristics of these cases and their relationship to the three specific designs evaluated by ORNL. The physics calculation geometric model was based on the Karlsruhe intermediate pressure design. In most calculations, 0.276 in. pins, spherical geometry from 1000 to 10,000 liters, an 18 in. depleted uranium blanket, and a Karlsruhe-type reflector were used. All cases assumed 15% clad-structure of Inconel-625. An equilibrium plutonium isotopic composition of 76.0, 21.0, 2.3, and 0.7% for 239Pu, 240Pu, 241, and 242Pu, respectively, was used for all cases. The methods used in the physics parametric study were chosen to conform, as closely as possible, to those used by ORNL so that a reasonably valid comparison could be obtained. The ORNL cross section set was used to help eliminate discrepancies in the nuclear analysis. Details of the physics calculations appear under Neutronics Survey.
