Hey guys, can someone provide insights on the computer codes used in the nuclear plant licensing process? I’ve come across computer codes such as RELAP, etc. What are these?

Suppose I am proposing a design to the NRC — what documents are required, such as PSR and DSR? I also wonder how PSRs are performed using event trees and fault trees. Are there any other computer codes or software commonly used?

Additionally, when is the Final Safety Analysis Report (FSAR) required?

This is for my information for an upcoming interview.

What are the general feelings behind the term “nuclear simulator” in this group? Doing a little test.
