Risk-Informed Systems Analysis
The Light Water Reactor Sustainability (LWRS) Program’s Risk-Informed Systems Analysis (RISA) pathway conducts research and development to optimize safety margins and minimize uncertainties to achieve high levels of safety and economic efficiency in nuclear power plants. The goal of these activities is to develop and deploy risk-informed technologies for use by the industry to enable more cost-effective plant operations.
Objectives, Research Areas and Outcomes
Objectives
Research and development to optimize safety margins and minimize uncertainties to achieve economic efficiencies while maintaining high levels of safety.
Develop technologies that provide precise information about the health of a component or system, track performance, identify potential degradation trends and provide an estimate of its expected failure time.
Enable planning and performance components maintenance operations at convenient times before failure is expected to occur.
Develop new methods to analyze data, propagate component health information from the component to the system level and optimize plant resources.
Develop more effective and efficient analytical methods and tools to support risk-informed decisions related to nuclear power plant equipment reliability and asset-management programs.
Develop data-analytics tools coupled with risk-informed methods to manage and optimize plant-asset life cycles, budgets and schedules.
Support enhanced system performance and health management, while reducing significantly labor needs.
