Determination of optimal core fissile loadings in the TREAT Upgrade reactor
The TREAT Upgrade (TU) reactor design is presently nearing completion. The reactor will be used to test LMFBR fuel under simulated accident conditions. The physics of the TU core is complicated by a number of factors related to the planned application of the facility. In this paper the design approach used to produce the core fissile loading spatial distribution needed to satisfy the requirement to test a number of different test clusters in various test loops in a transient operating mode is described. The TU core consists of a driver comprised of the pre Upgrade Zircaloy-clad TREAT fuel assemblies and a central converter region of new Inconel-clad fuel assemblies surrounding the test loop location. Separating the two concentric zones is a buffer zone that is made up of new Inconel clad assemblies operating at lower temperatures than the converter region.
