208. Configuration Studies for an ST-Based Fusion Nuclear Science Facility

Ms Laila El-Guebaly (USA)

18/10/2014, 08:30

Oral

A Fusion Nuclear Science Facility (FNSF) could play an important role in the development of fusion energy by providing the nuclear environment needed to develop fusion materials and components. The spherical tokamak (ST) is a leading candidate for an FNSF due to its potentially high neutron wall loading and modular configuration. A key consideration for the choice of FNSF configuration is the...

706. The Accomplishment of the Engineering Design Activities of IFMIF/EVEDA: the European-Japanese Project Towards a Li(d,xn) Fusion Relevant Neutron Source & Evaluation of Lithium Target Facility of IFMIF in IFMIF/EVEDA Project

Mr Juan Knaster (Japan)

Oral

A The International Fusion Materials Irradiation Facility (IFMIF), presently in its Engineering Validation and Engineering Design Activities (EVEDA) phase under the frame of the Broader Approach Agreement between Europe and Japan, has accomplished on summer 2013, on schedule, its EDA phase with the release of the engineering design report of IFMIF plant, which is here described, compliant with...

289. Overview of Fusion Reactor Materials Study at SWIP

Mr Xiang Liu (China)

18/10/2014, 09:10

Oral

Development of materials is an important issue for the future nuclear fusion reactors. In this paper, the developments and main achievements of fusion reactor materials at Southwestern Institute of Physics (SWIP) are overviewed by focusing on the plasma facing materials/components (PFMs/PFCs), structural materials and functional materials. For PFMs/PFCs, an ITER grade high purity tungsten and...

465. Molecular Dynamics and Density Functional Simulations of Tungsten Nanostructure Formation by Helium Plasma Irradiation

Mr Atsushi M. Ito (Japan)

18/10/2014, 09:30

Oral

The tungsten nanostructure induced by helium plasma irradiation had been found by the experimental researches for the plasma facing materials in fusion reactors. For the generation of the tungsten nanostructure, it is concerned about the decrease of the maximum allowable heat load and the erosion by arcing on the surface. To clear these problem, we had researched on the formation mechanisms of...

155. Neutron Irradiation Effects on Grain-Refined W and W-Alloys

Mr Akira Hasegawa (Japan)

18/10/2014, 09:50

Oral

Microstructural data of neutron irradiated W such as size and number density of voids and precipitates obtained by W up to 1.5dpa irradiation in the temperature range of 400-800C were compiled quantitatively. Nucleation and growth process of these defects were clarified and a qualitative prediction of the damage structure development and hardening of W in fusion reactor environments were...
