The FLECHT Low Flooding Rate Skewed Power shape tests is the second test series designed to expand the earlier FLECHT forced flooding rate data base for lower flooding rates. This report presents the evaluation, analysis, and model development efforts which have been performed on the skewed axial data. The overall objective of the FLECHT low flooding rate test program has been to obtain heat transfer data useful for calculating the reflooding behavior of a PWR core following a postulated loss-of-coolant accident. The behavior of the emergency core coolant (ECC) with respect to the mass stored and mass flow leaving the core during reflood is also needed for this purpose. The capability for meeting this latter need, has been made possible with the improved hardware and instrumentation of the cosine tests. The other main objective of the FLECHT low flooding rate test program is to provide valid data which can be used to verify/develop mechanistic reflood models.
