• In EU, a study, which was started in 2012, was continued to establish a Material Design Database for DEMO conceptual design activities.
• In Rokkasho, the license for handling tritium and other radio-active samples was obtained in July 2013.

★ 3rd 26 September 2014 @Barcelona, Spain

• A potential DEMO will be relatively large(plasma major radius ≳ 8 m) and low power (≤ 1.5-2 GW).
• In EU, the demonstration of electricity production before 2050 in a DEMO Fusion Reactor that produces its own fuel is the primary objective of EU program.
• An assessment of the database needed for design activities was proposed as collaboration between EUROfusion (EU) and Japan in Material research.

★ 4th 4 February 2015 @Univ. of Tokyo, Kashiwa Campus

• A new collaboration in tritium on the investigation in Rokkasho of dust sampled at JET started in 2014. A shipment containing dust sample of JET was transferred to Rokkasho R&D facility.
• Collaboration is successfully undertaken also on compatibility of SiC and SiC/SiC composites with liquid Pb-Li alloy.
• The status of EU database & issues addressed in design code activities were reviewed. Both in EU and JA, gap analyses are underway.

★ 5th 3rd November 2015 @Garching

• Compatibility of SiC/SiC composites with Li-Pb has been examined with rotating disk equipment capable of exposing samples with a wide range of parameters.
• Observation of JET-ILW tiles and dust was carried out with imaging plates and microscope. Many tungsten dust particles with acute angles were observed.
• Collaboration was agreed on a material database – with design rule issues as the common issues. JP-IA is positive to collaborate on acquiring the missing irradiation data.

★ 6th 3rd February 2016 @Nagoya University

• Key corrosion driving sources were identified by various characterization techniques such as SXES, rf-GD-OES, TPD- MS, etc. Corrosion was observed only with flowing Pb-Li, not with still Pb-Li.
• First results of tritium distribution, microstructure of decomposition layer and contents of both tiles and dust from JET- ILW experiments were obtained.
• In JA, the current preparation status of database (MPH) of F82H was summarised. The activities in the EDDI (Engineering Data and Design Integration) include gap analysis of EUROFER-97.

★ 7th 9th February 2017 @Kyoto University, Uji Campus

• Extension of IFERC project up to December 2019 was approved in BA SC-17. DEMO related activities in the extended period (2017/6-2019/12) will be implemented mostly as voluntary contributions.
• The EU-JA collaborative studies under the BA framework have produced very fruitful results. An apparatus for SiC/SiC composites was made by ENEA Frascati by using EU knowledge, and has been used for a series of corrosion experiments by JA by using JA knowledge. Several samples of tiles and dust from JET-ILW were sent to JA, and valuable data have been obtained by using unique JA facilities installed in a radiological controlled area. Several samples of functional materials have been exchanged between EU and JA.
• The material database of F82H was reconstructed.
