Improvement of the MARS subcooled boiling model for a vertical upward flow
Improvement of the MARS subcooled boiling model for a vertical upward flow
In the thermal-hydraulic system codes, such as MARS and RELAP5/MOD3, the Savannah River Laboratory (SRL) model has been adopted as a subcooled boiling model. It, however, has been shown that the SRL model cannot take into account appropriately the effects of inlet liquid velocity and hydraulic diameter on axial void fraction development.
