Research & Development
Validation and Uncertainty Quantification (VUQ)
Achieving credible, science-based predictive simulation capabilities
Objectives and Strategies
- VUQ is dedicated to developing overall Verification and Validation (V&V) approach
- VUQ will provide CASL with
- Best-estimate predictive capabilities with reduced uncertainties
- Capability for quantified predictive maturity assessments
- The Sensitivity Analysis and Uncertainty Quantification (UQ) process will guide CASL R&D investments and aid in designing future experiments
Requirements Drivers
- V&V and UQ methodologies and tools are needed by every Focus Area
- VUQ is the CASL “integrator” focused on:
- Access to software and underlying math models
- Validation data (at all physical scales)
- Partnerships with other Focus Areas to implement uniform VUQ practices
Outcomes and Impact
- Continuous evolution toward transformational, predictive computational simulation
- Capability to quantify and reduce uncertainties in nuclear modeling and simulation
- Mathematical tools and methodologies integrated and accessible to enable quantifying sensitivities and uncertainties in full-scale multi physics Pressurized Water Reactors (PWR) simulations
