Japan Aerospace Exploration Agency（JAXA）

The International Space Station (ISS), which flies about 400 km above the ground, is a special environment that is completely different from the ground, such as microgravity, space radiation, a vast field of view, a high vacuum, and abundant solar energy. It has been 10 years since the Japanese Experiment Module "Kibo" was installed on the ISS, and it has been established as a place for long-term and stable use of the space environment and technology demonstration, and a place (platform) for familiar space use. doing.

The "Electrostatic Levitation Furnace" (ELF) installed in "Kibo" has made it possible to create substances and acquire data, which was difficult on the ground. We are also taking on the challenge of new technologies such as measuring the physical properties of melts of refractory materials that take advantage of the fact that substances can be floated without a container. Experiments at Kibo are helping to create new innovations and technologies and enhance the competitiveness of Japanese manufacturing.

JAXA accepts requests for high-precision thermophysical property measurement using electrostatic levitation furnaces on the ground and in space. ELF can melt high melting point material which cannot be melted on ground. Then ELF can measure its thermophysical properties like density, surface tension, and viscosity. Please contact us first as some samples cannot be measured.

１．『技術士』とは
　技術士制度は、「社会的責任をもつて活動できる権威ある技術者」を育成、支援するために創設されました。
　技術士は、産業経済、社会生活の科学技術に関するほぼ全ての分野をカバーし、先進的な活動から身近な生活にまで関わっています。また、技術士は、国によって科学技術に関する高度な知識と応用能力が認められた技術者で、科学技術の応用面に携わる技術者にとって最も権威のある国家資格です。さらに、技術士は、「技術士法」により高い技術者倫理を備え、継続的な資質向上に努めることが責務となっています。
　その中でも、原子力・放射線部門は2004年に誕生した最も新しい部門です。
　技術士は専門的な応用能力を求められつつも、社会の実課題への対応を期待され、一般的な専門家の守備範囲よりもかなり広範な、横断的かつ基盤的な知見が必要とされます。原子力・放射線分野は総合技術であり、安全や倫理への社会的関心も高く、高度な見識、倫理観とそれを高水準に維持するための継続的研鑽が求められます。

２．技術士（原子力・放射線部門）の理念とビジョン
　私たちが考える『プロダクト』とは、社会からの信頼と安全の向上に資する役割を『技術士として』担うことで生まれるものです。
　一つは、一般社会に対する社会貢献で、原子力・放射線分野の専門的な知識を有しながら、中立的なレビューを行うことです。業界の代弁者であることはもちろん迎合であってもいけません。個人の高い倫理観に従い、地球的・歴史的な視点と国民の負担と便益、安全の確保の視点で考えることが必要です。このためには、専門知識に加え社会的な見識も問われます。
　もう一つは、原子力・放射線の専門分野に対して、技術士という資格に社会的に期待される自立的な視点でレビューを行うことが必要です。但し、このためには、求められる技術的専門性も有さねばなりません。
　そして、こういった活動を通じて、「技術士」を一つのキーワードとしながら、若い人々に生涯を通じて学び続ける姿勢を見せること、すなわち、「人材育成」を行うことも重要なプロダクトと考えます。
　このような思いを有した原子力・放射線部門の技術士とその職能集団である原子力・放射線部会をブランドイメージとして社会から広く認知していただき、活用していただくことが我々の目標、将来ビジョンであり、その活動内容をご紹介させていただくものです。
　展示内容を通じて、少しでも多くの技術者の方や学生の皆さんに、技術士に関心を持っていただければと考えております。

Hitachi-GE Nuclear Energy,Ltd.

Hitachi-GE Nuclear Energy, Ltd. has been providing a variety of solutions to the nuclear power plants throughout the overall plant lifecycle: design, development, construction, operation & maintenance, and decommissioning. In addition, based on our BWR development/construction experiences and fuel-cycle technologies, we are developing advanced reactors using international collaborations to reduce capital cost of the nuclear power plant project, reduce high level waste in the fuel cycle, and provide the long-term stable power supply.
Our booth presents the Development of the Advanced Reactors in Hitachi using application of innovative technologies.

Fuji Electric Co.,Ltd.

SIAL® is a geopolymer used for field of radioactive waste, and it is possible to solidify same way as the solidification of cement. It is able to solidify the spent ion exchange resin, simulated sludge, incineration ash, oil, concentrated liquid waste which are difficult to solidify by cement. Geopolymer is a general term formed by polycondensation of inorganic aluminosilicate components and it is attracting interest due to the confinement effect of cesium. SIAL® was developed by AllDeco Ltd (currently: Jacobs Nuclear Slovakia) and SIAL is first solidification material applied for radioactive waste disposal in the world. It acquired licence as the solidification meaterial of radioactive waste disposal from Slovakia Nuclear Regulator (UJD SR) in 2003 and Czech Nuclear Regulator (SUJB) in 2006. Fuji is proceeding development of SIAL® application of radioactive waste in Japan and currently conducting solidification of 200 litters drum in the laboratory at Kawasaki. Moreover, Fuji conducted first time in Japan to demonstrate of the solidification of the actual filter sludge and ion exchange coming from nuclear power plant, and it is already confirmed that it shows well characteristics of Kd and compressive strength as the waste body.
In this exhibition, we are introducing the following items: The process of disposal of radioactive waste and experiences in Slovakia.The characteristics of SIAL® : working time from viscosity after kneading, the outside and inside temperature of waste body itself, the result of solidification experiments from the nuclear power plant in Japan.

Health Effects of Radiation: 5 Themes

The Radiation Health Management Division and the National Institute of Radiological Sciences have jointly publicized the English version of the booklet, with cooperation of a group of experts, so that foreign nationals residing in Japan or visiting Japan or those interested in Japan can obtain basic knowledge on health effects of radiation and correctly understand changes in circumstances and efforts being made in Japan.
As terms used in this field are highly professional and difficult, we also prepared a glossary. We would like to extend our gratitude to the people who offered cooperation in checking the translation and preparing the glossary.
The booklet is also available on the website of the Ministry of the Environment, from which you can download the content for use in training and classwork. We hope that this booklet will be utilized in diverse occasions.

【MHI's Continuous Challenge to realize Fusion Energy】
MHI has been working on the ITER Project, which is an international project for fusion experimental reactors, and it is a challenge to realize fusion energy for the future.
MHI is involved in many of the components and systems procured by Japan and contributes to the successful completion of the ITER Project.
(This PJ is being promoted together with the National Institutes for Quantum Science and Technology.)
MHI has participated in the Fusion DEMO program and will continue to make efforts for the realization of Fusion Energy, the details are described here.

【MHI's efforts and contribution to ITER】
MHI is in charge of manufacturing 5 of 19 toroidal magnetic field coils (TF coils), which are the major components in the ITER tokamak machine. In January 2020, we completed the very first TF coil in the world and delivered it in February 2020. Up to now, we completed 4 units and shipped them to France.
Though the size of a TF coil is more than 10 m, it must be manufactured with a dimensional accuracy of a few mm, in order to confine plasmas stably. The TF coil structure is made from thick forgings to withstand a huge electromagnetic force during operation.




【MHI's manufacturing technologies】

The TF coil is a huge structure with a height of 16.5 meters, a width of 9 meters for a total weight of more than 300 tons, and it is manufactured with an accuracy of 1/10,000 or less. We have established advanced welding technologies in order to avoid excess welding deformation.
As for manufacture of the Divertor, we established bonding technology between tungsten and copper alloy, welding technology for dissimilar materials (copper alloy and stainless steel) and non-destructive inspection technology through performing preliminary tests and manufacturing protypes.
