A descriptive plan is presented of tests for the Unblocked Bundle, Forced and Gravity Reflood Task of the Full-Length Emergency Core Heat Transfer for the Separate Effects and Systems Effects Tests (FLECHT-SEASET) program. These tests consist of forced and gravity reflooding experiments utilizing electrical heater rods to simulate current nuclear core fuel rod arrays (for example 17 x 17 assemblies) of PWR and PWR fuel vendors. All tests will be performed with a cosine axial power profile. These tests will be used to determine effects of fuel rod size on reflooding behavior, to aid in development/verification of computational methods in predicting reflooding behavior of newer fuel rod array geometries, and to serve as a baseline for determining the effects of blockage in future flow blockage bundle tests.
