[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] Summary: • Development of the next version of G4ECONS is progressing well; • Comparable results obtained from the benchmarking of G4ECONS, HEEP and H2A for hydrogen production; • Completed benchmarking G4ECONS with NEST in collaboration with IAEA: –Once-through SCWR; – Two fast reactors with closed fuel cycle.
[en] Conclusion: • GIF Cost Estimating Methodology is available for use by all GIF projects. • Training for users is available at varying levels of detail. • The EMWG continues to monitor Methodology applications. • Small scale activities on additional GEN IV related case studies.
[en] EMWG - Plans for the future: - Continue improvements to G4ECONS v3.0; - Seek feedback from SSCs using survey questionnaire; - Discuss and agree on further collaboration with IAEA; - Publication of work on benchmarking; - Monitor use of the methodology and seek feedback; - Maintain watch on international activities on nuclear economics.
[en] The Interface Meeting will discuss the increased role of evolutionary nuclear systems,,, including small modular reactors, nuclear cogeneration, next generation reactors and advanced fuel cycles. This meeting can also help identify the demands for the GIF and IAEA's cooperation areas and assist us in developing proper programmes to cope with the challenges of developing evolutionary nuclear systems.
[en] Conclusion: • Excellent alignment in capital, O&M and D&D costs has been demonstrated for G4ECONS and NEST. • Discrepancies between G4ECONS and NEST major results are similar to those among different systems of NEST (HU, MIT etc) and normally stay within 1-2%. • Potential future joint activities of EMWG and INPRO are currently under discussion.
[en] In this study the equilibrium closed fuel cycle was simulated for eight selected fast reactors and both U-Pu and Th-U fuel cycles. For simplicity, the fission products were neglected and the reactors were represented only by infinite lattices. It was found that the fuel composition in equilibrium cycle is stabilized and does not differ between two consecutive iso-breeding cycles. The equilibrium fuel composition also determines the excess reactivity. This reactivity should be high enough to accommodate the expected captures of fission products and the presumed neutron leakage. The remaining reactivity, if available, can be applied for additional breeding or burning of selected isotopes. The study provided insight for the differences between the eight fast reactors and also between the U-Pu and Th-U closed fuel cycles. (author)
[en] Questions of staff training for the implementation of innovative projects in the field of nuclear energy are discussed. On the example of the National research nuclear University MEPhI, having wide experience in the training of personnel for nuclear power, the classification of types of activities and stages of training of experts in the implementation of technologies of fast reactors are presented. The stages of development of the Department Technology of closed nuclear fuel cycle, created for target training of specialists for the project Proryv.
