This text describes NEs approach to advanced nuclear reactor R&D and examines how NE plans and prioritizes its advanced reactor R&D activities, including deploying an advanced reactor. This book also discusses the DOE's International Thermonuclear Experimental Reactor (ITER) Agreement. It examines how and why the estimated costs and schedule of the U.S. ITER Project have changed since 2006; the reliability of DOEs current cost and schedule estimates; and actions DOE has taken to reduce U.S. ITER Project costs and plan for their impact on the overall U.S. fusion program.
