Fusion Materials Development at Forschungszentrum Jülich
Advanced Engineering Materials, Volume 22, Issue 6, June 2020., 2020 In fusion material research, the focus has been twofold‐plasma facing and structural materials allowing to withstand the extreme conditions such as neutron bombardment and high heat fluxes. In this contribution, the background for the choice of tungsten as first wall material is given and the advanced materials developed at Forschungszentrum Jülich ...

Compilation of Existing Neutron Screen Technology
Science and Technology of Nuclear Installations, Volume 2014, Issue 1, 2014., 2014 The presence of fast neutron spectra in new reactors is expected to induce a strong impact on the contained materials, including structural materials, nuclear fuels, neutron reflecting materials, and tritium breeding materials. Therefore, introduction of these reactors into operation will require extensive testing of their components, which must be ...

Radioactive Iodine and Krypton Control for Nuclear Fuel Reprocessing Facilities
Science and Technology of Nuclear Installations, Volume 2013, Issue 1, 2013., 2013 The removal of volatile radionuclides generated during used nuclear fuel reprocessing in the US is almost certain to be necessary for the licensing of a reprocessing facility in the US. Various control technologies have been developed, tested, or used over the past 50 years for control of volatile radionuclide emissions from used fuel reprocessing ...

Decay Heat Removal in GEN IV Gas‐Cooled Fast Reactors
Science and Technology of Nuclear Installations, Volume 2009, Issue 1, 2009., 2009 The safety goal of the current designs of advanced high‐temperature thermal gas‐cooled reactors (HTRs) is that no core meltdown would occur in a depressurization event with a combination of concurrent safety system failures. This study focused on the analysis of passive decay heat removal (DHR) in a GEN IV direct‐cycle gas‐cooled fast reactor (GFR ...

Gas‐Cooled Fast Reactor: A Historical Overview and Future Outlook
Science and Technology of Nuclear Installations, Volume 2009, Issue 1, 2009., 2009 A review is given of developments in the area of Gas‐Cooled Fast Reactors (GCFR) in the period from roughly 1960 until 1980. During that period, the GCFR concept was expected to increase the breeding gain, the thermal efficiency of a nuclear power plant, and alleviate some of the problems associated with liquid metal coolants.

The International Journal of Advanced Manufacturing TechnologyAbstractThe production of lithium-rich ceramic pebbles is crucial for future fusion reactors, as they are one of the most important components of the tritium-breeding blankets. In order to produce high-quality pebbles, a melt-based fabrication process KALOS (KArlsruhe Lithium OrthoSilicate) has been developed at the Karlsruhe Institute of Technology ...
