![]() ![]() ![]() Based on the discussions held at the workshop, five Priority Research Directions (PRDs) were identified. To identify the key research directions required to discover the chemical processes and material degradation mechanisms that result in loss of performance of the more ยป fuel, coolant, and structural materials, nearly 150 theoreticians, computational experts, and experimentalists from industry, national laboratories, academia, and federal agencies participated in a workshop held in August 2017. Success will provide an energy source needed to secure a stable and safe energy supply for the nation. There is now the prospect of designing materials that report upon their own damage, are self-healing, and leverage what would be considered deleterious chemical processes to increase their performance within advanced reactor designs. To address the challenge of stringent demands on material systems as their properties and performance continuously evolve over the operational lifetime, the frameworks to uncover the underlying processes that cause reduced performance have been developed over the last decade. Recent advances in chemistry and materials sciences provide an unprecedented opportunity to develop the critical systems-the fuel, coolant, and structural materials-needed for deployment of advanced nuclear reactor designs. In contrast to current nuclear power facilities, future concepts operate at higher temperatures, are operationally more efficient, more fully utilize the energy stored within the fuel, and reduce the amount of waste produced. It provides reliable energy that helps to stabilize the national grid. Nuclear power today accounts for approximately 20% of the electrical supply for the US. ![]()
