Description
Information has been obtained on the flow distribution along parallel paths, on the
situation of the free levels, on the heat and mass transfer processes. Experimental
determination of the hydraulic parameters is only possible for the components of the core by
using full-scale mock-ups. The remaining elements of the circulation loop require calculation
justification supported by experiments on fragmentary models. The three-dimensional flow in
the first loop of the reactor requires using of computational fluid dynamics methods (CFD).
The computational model includes the porous domains (the core and the steam
generator modules) and the area for which the RANS simulation is performed. The hydraulic
parameters of the porous domains are defined on the basis of experiments (for the components
of the core) and the prior CFD calculations (for the SG modules). When creating the
computational model the experience of the CFD code verification from the point of view of
the modeling of the liquid metal coolants flow was taken into account.
The main design parameters of the reactor circulation loop are confirmed. The
information on the spatial distribution of the thermal parameters of the coolant is useful for
clarifying of the stress-strain state of the structural elements, and in the formulation of the
requirements for the placement of the reactor control system sensors.
