Separate Effect Test Assessment about Interfacial Heat Transfer Model and Correlations in SPACE Code

The development of Safety and Performance Analysis CodE (SPACE) has been in the second period, in which the main goal is a validation. The source terms that are related to the models and correlations are continuously modified in view of the smoothness and robustness after the first stage development. In addition, the solution quality is the next purpose in the second development period. In the second stage, it is focused to assess the physical models and correlations of SPACE code by using the well known SET problems. For the successful SET assessment procedure, a problem selection process has been performed with the leading of KEPRI. KEPRI has listed suitable SET problems according to the individual assessment purpose. The interfacial heat transfer has 3 topic problems to validate: I) MIT ST4, II) Super Moby Dick, III) GE Level Swell. First topic is about the pressurizing condensation. Others are about the choking and flashing
