A simplified core model of the SCWR

The Canadian concept of SCWR is a light-water cooled, heavy-water moderated, pressure-tube reactor. The full core of Canadian-SCWR used to be modeled using 20 different axial positions each has its own thermal-hydraulic parameters (like fuel temperature, coolant density, etc.). In this paper the validity of using a lower number of nodes in the full-core model has been assessed. Using fewer nodes will not only reduce the computational time of …
