I have a few questions regarding codes typically used in core design:(adsbygoogle = window.adsbygoogle || []).push({});

1) Which codes need to be coupled with a TH module and which do not? From what I have gathered, steady state codes can be coupled with a code like RELAP to model transients.

2) Are independent codes that are coupled to one another than codes with a TH module internally? SIMULATE can run transients, but is the TH side of it as good with whatever it is using the those calculations?

3) PARCS seems to be a fairly new code being developed (not very new, but new enough). How does this code differ from SIMULATE and why was it developed?

4) Are Monte-Carlo codes truly the best...once the computing power is there? It seems that probabilistic would be a most accurate, but how much worse are deterministic codes and how much better can they become?

Thanks for your help. I hope my questions make sense.

Regards,

Uranium
