Edge blockage in a 19-pin sodium-cooled bundle. [LMFBR]

Conference ·
OSTI ID:5356275
To assess the effect of partial flow blockages on the local temperature distributions in LMFBR fuel assemblies, several experiments have been carried out at the Thermal-Hydraulic Out-of-Reactor Safety (THORS) Facility at the Oak Ridge National Laboratory. Two kinds of flow blockages have been investigated: (1) six-channel internal blockage for which the blocked channels are not adjacent to the duct wall, and (2) 14-channel edge blockage for which some of the blocked channels are adjacent to the wall. The larger edge blockage is generally more severe than the internal blockage due to higher temperature rises in the wake behind the blockage. The experimental results on the edge blockage are analyzed and presented.
