claimAdvanced nuclear reactor designs rely more on passive safety mechanisms than conventional light water reactors, with some concepts approaching 'walkaway' safety where no external intervention is required for safe shutdown.
claimThe United States regulatory environment is generally regarded as providing a strong framework for licensing established light water reactor power plant designs, but it is less well suited for licensing more advanced nuclear reactor concepts.
claimMany advanced nuclear reactor designs are small, modular systems intended to be constructed primarily in factories rather than in the field.
perspectiveThe National Academies of Sciences, Engineering, and Medicine recommends that the U.S. Nuclear Regulatory Commission (NRC) prepare for a rulemaking on the licensing of advanced nuclear reactors that establishes a risk-informed regulatory pathway for non-light water reactor technologies and a staged licensing process with clear milestones from conceptual design to commercial deployment.
claimGroups within the U.S. industry, national laboratories, and universities have launched efforts to develop advanced nuclear power reactor and fuel-cycle technologies to reduce economic costs, enhance safety, facilitate waste management, and lessen proliferation risks.
claimAdvanced nuclear reactor designs are hampered by a lack of suitable national facilities capable of conducting tests at the high temperatures and high neutron flux densities required for many new designs.
claimThe U.S. Nuclear Regulatory Commission (NRC) may lack the necessary experience and resources to establish a timely, predictable, and well-defined licensing process for advanced nuclear reactors in the United States.
claimSome advanced nuclear reactor designs are optimized to minimize waste production or to burn nuclear waste generated by other reactors.
measurementAdvanced nuclear reactor designs vary in output capacity, with some reaching the 1,000 megawatt (MW) range, similar to large conventional light water reactors, while others are compact designs ranging below 50 MW.
perspectiveThere is currently no clear pathway to determining the commercial viability of advanced nuclear reactor systems, with varying views on their economic feasibility and the time required for commercialization.
claimAdvanced nuclear reactor designs capable of rapid and efficient load following are well-suited for electrical grids that integrate large amounts of intermittent solar and wind power generation.
Impact of carbon dioxide removal technologies on deep ... - Nature nature.com Nature Jun 17, 2021 9 facts
claimThe inclusion of carbon removal technologies in power systems reduces the dependence on other technologies such as advanced nuclear power and long-duration energy storage.
measurementIn a 100% CO2 reduction cap scenario, carbon dioxide removal (CDR) lowers advanced nuclear capacity from 117 GW to 47 GW when using Direct Air Capture (DAC) plus Bioenergy with Carbon Capture and Storage (BECCS), or to 73 GW when using DAC only.
claimCDR availability decreases the generation and capacity of advanced nuclear, renewables, and long-duration energy storage technologies, as these are replaced by gas turbine capacity in the model.
claimIn scenarios without carbon dioxide removal (CDR), the capacity of advanced nuclear, renewables, and long-duration energy storage increases for CO2 reduction targets greater than 80%.
claimThe availability of carbon dioxide removal (CDR) technologies decreases the generation and capacity from advanced nuclear, renewables, and long-duration energy storage, as these technologies are used to replace gas turbine capacity, especially under more stringent policy scenarios.
claimWithout CDR, the capacity of advanced nuclear, renewables, and long-duration energy storage increases for CO2 reductions greater than 80%.
claimAs policy ambition increases, the impact of Carbon Dioxide Removal (CDR) technologies becomes more significant, reducing the dependence on technologies such as advanced nuclear and long-duration energy storage.
claimWithout carbon dioxide removal (CDR) technologies, the capacity of advanced nuclear, renewables, and long-duration energy storage increases for CO2 reductions greater than 80%.
claimAs policy ambition for decarbonization increases, the impact of carbon dioxide removal (CDR) technologies becomes more significant, reducing the electric sector's dependence on technologies like advanced nuclear power and long-duration energy storage.
