The Department of Energy (DOE) Reactor Concepts Research, Development, and Demonstration (RD&D) program uses taxpayer funding to develop and demonstrate new commercial reactor designs. The program includes research and development of small modular reactors, light water reactor improvement and advanced reactor designs. Renamed in fiscal year 2011, the Reactor Concepts RD&D program was formerly the Generation IV Nuclear Energy Systems Initiative, which was created in 2000 and succeeded a number of government nuclear energy R&D efforts dating back to the 1950s.
