Sub-Channel Analysis Code: STAFAS
The sub-channel analysis code STAFAS was originally developed for single phase super-critical pressure water cooled reactors.
- Fluids of single phase flow with arbitrary variation of properties
- Complex fuel assembly configuration
- Capability of macro-channel approach
- High flexibility of user interaction and application extension
- High numerical stability
- Super-critical water cooled reactors (SCWR)
- Heavy liquid metal cooled reactors
|Figure 1: SCWR fuel assembly with square lattice||Figure 2: Coolant temperature in three different sub-channels|
The figure on the right side shows the coolant temperature in different sub-channels of a SCWR fuel assembly with square lattice, as indicated in the left figure. In the next step, the STAFAS code will be extended to HLM-cooled reactors.
