However, it appears reasonable to conclude that
high temperatures probably would exist in the thin,
low-velocity layer of fluid in the 10-deg divergent
channel because the flow there is probably laminor
in nature.
A report is being prepared which will be useful
to designers for predicting wall-cooling require-
ments in circulating-fuel reactors which have pipe,
parallel-plate, or annular fuel-duct geometries.
The temperature solutions, which were presented
pre~io~sly,’~~~~ have been tabulated in detail so

that the superposition process outlined in those
reports can be quickly effected. Cooling require-
ments and resulting fluid temperature distributions
have been determined for typical circuloting-fuel
reactor systems
