Illustrations Tables and Figures. Rear cover creased. The potential for using fusion energy to produce commercial electric power was first explored in the 1950s. Harnessing fusion energy offers the prospect of a nearly carbon-free energy source with a virtually unlimited supply of fuel. Unlike nuclear fission plants appropriately designed fusion power plants would not produce the large amounts of high-level nuclear waste that requires long-term disposal. Due to these prospects many nations have initiated research and development R&D programs aimed at developing fusion as an energy source. Two R&D approaches are being explored: magnetic fusion energy MFE and inertial fusion energy IFE. An Assessment of the Prospects for Inertial Fusion Energy describes and assesses the current status of IFE research in the United States; compares the various technical approaches to IFE; and identifies the scientific and engineering challenges associated with developing inertial confinement fusion ICF in particular as an energy source. It also provides guidance on an R&D roadmap at the conceptual level for a national program focusing on the design and construction of an inertial fusion energy demonstration plant. The committee's final report represents the consensus of the committee after six meetings see Appendix C for the meeting agendas. The first four meetings were concerned mainly with information gathering through presentations while the final two meetings focused on carrying out a detailed analysis of the many important topics needed to complete the committee's assessment. This report describes and assesses the current status of inertial fusion energy research in the United States identifies the scientific and engineering challenges associated with developing inertial confinement fusion as an energy source compares the various technical approaches and finally provides guidance on an R&D roadmap at the conceptual level for a national program aimed at the design and construction of an inertial fusion energy demonstration plant including approximate estimates where possible of the funding required at each stage. At the outset of the study the committee decided that the fusion-fission hybrid concept was outside the scope of the study. While they are certainly interesting subjects of study comparisons of inertial fusion energy to magnetic fusion energy or any other potential or available energy technologies such as wind or nuclear fission were also outside the committee's purview. Although the committee carried out its work in an unclassified environment it was recognized that some of the research relevant to the prospects for inertial fusion energy was conducted under the auspices of the nation's nuclear weapons program and has been classified. Therefore the NRC established the separate Panel on the Assessment of Inertial Confinement Fusion ICF Targets to explore the extent to which past and ongoing classified research affects the prospects for practical inertial fusion energy systems. The panel was also tasked with analyzing the nuclear proliferation risks associated with IFE; although that analysis was not available for inclusion in the interim report the committee reviewed the panel's principal conclusions and recommendations on proliferation and these are included in this final report of the committee. The target physics panel exchanged unclassified information informally with the committee in the course of the study process and the committee was aware of the panel's conclusions and recommendations as they evolved. The panel produced both a classified and an unclassified report; the latter was timed so as to be available to inform this committee's final report; the Summary of the panel's unclassified report prepublication version is included as Appendix H.

2013réf. 67299Washington DC: The National Academices Press 2013. Prepublication Copy--Subject to Further Editiorial Correction. Wraps. Very good. Cover has some wear and soiling. Various paginations approximately 225 pages. Includes illustrations. Bbliography of previous ICF studies consulted. Glossary. Title continues: "Physics and Astronomy. Committee on the Prospects for Inertial Confinement Fusion Energy Systems." From a National Academies internet posting: "The energy produced by nuclear fusion has the potential to provide a low-carbon base-load source of electricity; however significant scientific and engineering efforts are still required before the feasibility of a commercial fusion plant can be established. Initiating fusion based upon magnetic confinement and inertial confinement of the fusion plasma have been studied for decades. In inertial confinement fusion ICF a driver delivers energy to the surface of a pellet of fuel heating and compressing it. There are many approaches for initiation fusion using inertial confinement. For example different driver concepts have very different operating conditions and characteristics. Understanding the strengths and weaknesses of each approach is central to the effort to develop IFE as a power source. Given the current level of activity in ICF research now is an appropriate time to consider how to proceed regarding inertial fusion as a potential power source. An NRC committee and panel will be formed to provide findings and recommendations to advise DOE on the development of an R&D roadmap for inertial fusion energy. All the approaches to ICF will require much investigation and will need to be considered in any long-term R&D strategy." The National Academices Press paperback
