Verification, Validation and Uncertainty Quantification:
• Our top priority recommendation is that a V&V and
UQ program for nuclear systems’ simulation take a
• First, focus on research into the critical issues
• Second, a concurrent study using the V&V and
UQ process to analyze a number of critical,
integrated physics applications would provide a
problem focus and address the issues of
coupled multi-scale physics and UQ.
If you care about having useful models, then you care about VV&UQ. Otherwise, a model just provides the colorful marketing material you use to garner more funding. Larzelere goes on to say,
It is Important to Note That Advanced Modeling and Simulation Does Not Replace the Need for Theory or ExperimentsAs an aside, I thought this graphic comparing the manpower and flops requirements of the two different simulation domains was interesting too.
