The THETIS 80% blocked cluster experiment. Pt. 3
Description
Thermal-hydraulics experiments on a model PWR fuel assembly containing partial blockage are reported. Extensive data on the rewetting of the cluster are presented. Above the rewetting front the surface heat flux decreased with height because of the increasing superheating of the steam in the two-phase coolant. Heat transfer in the blockage was good early in the transients but deteriorated later. Cooling of the 80 percent blockage was generally no better than with the 90 percent blockage. There is good agreement between the experimental data and predictions using BERTHA. (U.K.)
