There are currently 438 nuclear power plants in operation around the world, producing 16% of the world's electricity---the largest share provided by any nongreenhouse-gas-emitting source.
The organization and execution of the roadmap became the responsibility of a Roadmap Integration Team that is advised by the Subcommittee on Generation IV Technology Planning of the U.S. Department of Energy's Nuclear Energy Research Advisory Committee (NERAC).
As preparations for the Generation IV Technology Roadmap began, it was necessary to establish goals for these nuclear energy systems.
In addition to overall summaries regarding fuel cycles and overall sustainability, the section describes missions and economic outlook, approach to safety and reliability, and path forward on proliferation resistance and physical protection.
As a reference case, the FCCG determined waste generation and resource use for the once-through cycle.
The traditional mission for civilian nuclear systems has been generation of electricity, and several evolutionary systems with improved economics and safety are likely in the near future to continue fulfilling this mission.
Eight candidate reactor designs were evaluated with respect to six commercialization and regulatory readiness criteria, including advanced boiling water reactors, pressurized water reactors, and gas-cooled reactors.
Crosscutting R&D for evaluation methods is found in the Crosscutting R&D sections on fuel cycles, risk and safety, economics, and proliferation resistance and physical protection.
