Optimization of Excess Reactivity and Power Profile in a Linear Breed-and-Burn Fast Reactor

摘要

It was found that by using the concave Zr-zoning in the initial core of the B&BR, the maximum excess reactivity can be lower than 1.0 dollar and the radial power profile can also be successfully flattened by using the Zr-zoning. The concave concept deserves more investigations for better performances of the B&BR core.
