IAEA-TECDOC--1356: Emerging nuclear energy and transmutation systems: Core physics and engineering aspects

Proceedings of a Committee Meeting (TCM) on “Core Physics and Engineering Aspects of Emerging Nuclear Energy Systems for Energy Generation and Transmutation” held in Argonne, Illinois, U.S.A., 28 November - 1 December 2000

International Atomic Energy Agency, Vienna (Austria), IAEA-TECDOC--1356

Abstract

The recycling of plutonium, minor actinides and long-lived fission products in various types of fission reactors, accelerator driven systems (ADS) and molten salt reactors is under investigation in several Member States. The surmised advantages of some of these concepts, e.g. ADS, are intrinsic low waste production, high transmutation capability, enhanced safety characteristics and better long-term resources utilization (e.g. with thorium fuels). Important R&D programmes are being undertaken by various institutions in many Member States to substantiate these claims and advance the basic knowledge in this innovative area of nuclear energy development. For these groups there is the clearly perceived need for coordinating their efforts and also for getting access to information from nationally and internationally coordinated activities.

While long term objectives for developing novel nuclear systems for energy production and transmutation may not be unanimously agreed upon by the different groups participating in this effort, it is clear that the short-term goals are similar. Thus, it is useful to exchange technical information developed in the different approaches and to identify areas of cooperation.

The objectives of this TCM were threefold: to review the status of R&D activities in the area of hybrid systems for energy generation and transmutation, to discuss specific scientific and technical issues covering the different R&D topics of these systems; and to recommend to the IAEA activities that would be specifically targeted to the needs of the Member States performing R&D in this field.
