I am quite confused for the thermal-hydraulic codes for cores and the thermal-hydraulic codes for systems. I know COBRA is a thermal-hydraulic code for cores and RELAP is a thermal-hydraulic code for systems. For the reactor transient analysis, Does it need to couple the neutron kinetics codes (like PARCS) with the thermal-hydraulic codes for cores(like COBRA) and then couple with the thermal-hydraulic codes for systems (like RELAP)? Or, only one kind of thermal-hydraulic codes is needed to be coupled?
Some code like SIMULATE and SIMULATE-3k should have thermal-hydraulic feedback themselves. Is that thermal-hydraulic feedback just like the thermal-hydraulic codes for cores? And, does it still need to couple the thermal-hydraulic codes for systems (RELAP) to do the reactor transient analysis? Does PARCS have such thermal-hydraulic feedback inside the code?
Thank you!
