ECC delivery and distribution in scaled PWR experiments

OSTI ID:6526033
Reactor Safety research currently being conducted in the LOFT and Semiscale experimental facilities has produced experimental results relevant to emergency core coolant (ECC) licensing calculations. LOFT, Semiscale, and commerical PWRs are related through a volume scaling rationale which permits identification of the trends in the thermal-hydraulic phenomena in scaled research facilities. Additionally, the thermal-hydraulic phenomena in PWRs can be bounded through application of the scaling rationale. The experimental ECCS results relevant to licensing were obtained principally from the two LOFT experiments described. Experimental results from the Semiscale program and other LOFT experiments are used where required in extending the trends of the thermal-hydraulic phenomena in the scaled systems to commerical PWRs. ECCS capability is discussed herein in terms of the ECC delivery delay to the lower plenum and the undelivered ECC to the reactor vessel during ECCS operation.
