The Light Water Reactor Sustainability (LWRS) Program, sponsored by the U.S. Department of Energy (DOE) and coordinated through a variety of mechanisms and interactions with industry, vendors, suppliers, regulatory agencies, and other industry research and development (R&D) organizations, conducts research to develop technologies and other solutions to improve economics and reliability, sustain safety, and extend the operation of nation's fleet of nuclear power plants. The LWRS program has two objectives to maintain the long-term operations of the existing fleet: 1) to provide science and technology-based solutions to industry to o implement technology to exceed the performance of the current business model; and 2) to manage the aging of systems, structures, and components (SSCs) so nuclear power plant lifetimes can be extended and the plants can continue to operate safely, efficiently, and economically. Knowledge and understanding of risks is essential to success of the program objectives and because of it LWRS program has numerous research projects exploring risk-informed approaches. This panel will discuss use of risk information in various applications at each pathway: plant modernization, flexible plant operation and generation, risk-informed systems analysis, materials, and physical security.
