ABSTRACT
A large-scale model simulating one channel of a foal subassembly,
promoted for the SCW reactor, was built. This subassembly consisted if
alternate flat and corrugated fuel plates. The channel waits ul the modal
were healed electrically and the beat waa removed by a coolant flowing
through the model at atmoapherlc preaaure. The temperature diatrlbutlun
around the periphery waa measured for varloua coolant* and flow rates,
choaen to bracket reactor conditions. From (heat data, local heat-transfer
coefficients were calculated.
The model coefficients were Interpolated to obtain an Isothermal
distribution of heat-transfer coefficients for three stations along the reactor
channel. These heat-transfer coefficients and data on heat transfer to
supercritical water in circular tubes were uaed to calculate the tempera-
ture field in the fuel plate* of the subassembly.
The method of cyclic heat was uaed to measure the average heat-
transfer coefficient in the subassembly. The experimental data are plotted
as Stanton number versus Reynolds number,
