Systems Uncertainty Analysis
N&R developed the Systems Uncertainty Analysis (SUA) generic software tool that enables users to perform probabilistic systems analyses using legacy deterministic simulation codes such as ROCETS, NPSS, NEPP, INTROS, SCORES, and LRE_Designer. This code uses a graphical user interface that facilitates easy input and on-screen graphical output.
