“…As an example, the ATHLET thermal hydraulic code developed at the GRS, Society for Plant and Reactor Safety, was planed to analyse leaks and transients for power reactors. However, to extend the applicability of the code to the safety analysis of research reactors, a model was implemented permitting a description of the thermal-dynamic non-equilibrium effects in the subcooled boiling regime (Hainoun et al, 1996). In the same way, the RELAP5 code has been modified to better simulate the research reactors operation conditions (low pressure, low mass flow rate, low power).…”

“…Some of these codes explicitly include the basic bubble parameters invoked above (nucleation site density, bubble frequency, and departure size) in an attempt to capture the complexity of subcooled boiling, particularly under low-pressure conditions. e.g., 54) This mechanistic approach has also been adopted in certain core codes, e.g., 55) system codes, e.g., 56) and extensively in computational fluid dynamics (CFD) codes. e.g., [57][58][59] The role of nucleation site density and its suppression under convective conditions has also been recognized as important for predicting the interfacial area concentration in two-fluid T-H codes.…”
