[en] The investigation of the thorium fuel cycle (ThFC) is a collaborative INPRO (International Project on Innovative Nuclear Reactors and Fuel Cycles) activity within its main area on global vision on sustainable nuclear energy for the 21st century. The current publication reports on the sustainability of nuclear power by re-examining the potential of thorium-based fuel cycles to support future large scale deployment of nuclear energy systems by increasing the availability of nuclear material. Special attention is paid to the thorium fuel cycle from the point of view of economics and proliferation resistance.
[en] This paper attaches tables summarising the information received in reply to the questionnaire (INFCE/DEP./WG4-28) together with modifications, corrections and additions subsequently made
[en] The future program which has been approved by the Federal Government in fall 1974 is based on the following: plutonium recycle at least within the next decade is a necessity. It has been shown that it is technically and economically feasible to introduce well designed plutonium elements in water reactors
[en] The paper restates the prime objectives of Working Group 4 and explains that in order to accomplish these objectives two sub-groups (A and B) have been established. The Co-Chairmen suggested that sub-group A divided their work into 16 tasks, which are listed in the paper with proposals for how the sub-group should approach them
[en] The items discussed include the collection of basic data, current methods of plutonium storage: base case, technological alternatives for plutonium storage, technological alternatives for plutonium transport, alternative institutional arrangements, assessment of base cases, plutonium recycle: reactor alternatives, plutonium recycle: reprocessing alternatives
[en] The paper is considering the changes in delayed neutron fraction, reactivity coefficients, and control rod reactivity associated with plutonium insertion. Description of fuel assembly and core design, plutonium recycle fuel management and experience of KWU reactors as well as KWU development programme is given (author)
[en] In this meeting we will continue the established tradition to inform each other about the most important achievements of both projects and results of activities identified on last meeting which include areas of Proliferation Resistance, Economics, Safety, and Non-electric applications. We are also expecting discussion of new areas of potential cooperation such as Modelling and Simulation, SMRs, Institutional innovations, Advanced fuel cycles including Thorium, advanced materials, and Education and Training.
[en] The feasibility of the thermal plutonium recycle system has been demonstrated in the German Federal Republic. The German concept includes the co-location of reprocessing and MOX fabrication plants. Transport will be limited to that of fuel elements between the reactors and the fuel cycle centre. Journey times in the Federal Republic will be short (one day). IAEA safeguards goals will be fulfilled with the same measures as are currently applied to uranium oxide fuel elements
