R&D on Accelerator Driven Nuclear Transmutation System (ADS) at J-PARC, 1; Accelerator Driven Nuclear Transmutation System (ADS)

Maekawa, Fujio

Purazuma, Kaku Yugo Gakkai-Shi, 98(5), p.201 - 205, 2022/05

The nuclear transmutation technology is a powerful solution to the "nuclear waste" problem that accompanies nuclear power generation. The Accelerator Driven System (ADS), which combines a high-intensity accelerator and a subcritical core, is a promising tool for nuclear transmutation. In this paper, we will explain the significance and principle of nuclear transmutation by ADS, design examples of ADS, partitioning and transmutation technology and its effects, required performance of high-intensity accelerators, overseas trends, etc.

Collaboration between SCK$$cdot$$CEN and JAEA for Partitioning and Transmutation through Accelerator-Driven System

Working Group for Collaboration between SCK$$cdot$$CEN and JAEA for P&T through ADS

JAEA-Review 2017-003, 44 Pages, 2017/03

JAEA-Review-2017-003.pdf:5.35MB

This technical report reviews Research and Development (R&D) programs for the Partitioning and Transmutation (P&T) technology through Accelerator-Driven System (ADS) at Studiecentrum voor Kernenergie/Centre d'Etude de l'$'e$nergie Nucl$'e$aire (SCK$$cdot$$CEN) and Japan Atomic Energy Agency (JAEA). The results obtained in the present Collaboration Arrangement between the two organizations for the ADS are also summarized, and possible further collaborations and mutual realizations in the future are sketched.

Highly practical and simple ligand for separation of Am(III) and Eu(III) from highly acidic media

Suzuki, Hideya; Tsubata, Yasuhiro; Kurosawa, Tatsuya; Shibata, Mitsunobu; Kawasaki, Tomohiro; Urabe, Shunichi*; Matsumura, Tatsuro

Analytical Sciences, 32(4), p.477 - 479, 2016/04

 Times Cited Count:18 Percentile:67.29(Chemistry, Analytical)

An impeccable, high-performance new reagent called alkyl diamide amine (ADAAM) was examined from the viewpoint of mutual separation of Am(III) and Eu(III). ADAAM has three donor atoms, one soft N-donor atom and two hard O-donor atoms, in the central frame. The combination of soft and hard atoms affords a tridentate donor set of atoms that ensures remarkable extractability and selectivity of Am(III) and Eu(III) in highly acidic media.

Geologic disposal of radioactive waste produced by application of partitioning-transmutation technology to nuclear fuel cycle

Nakayama, Shinichi; Morita, Yasuji; Nishihara, Kenji; Oigawa, Hiroyuki

Proceedings of International Conference on Nuclear Energy System for Future Generation and Global Sustainability (GLOBAL 2005) (CD-ROM), 6 Pages, 2005/10

The effects of partitioning-transmutation (PT) technology to waste management was assessed based on the chemical and physical properties and estimated amounts of radioactively contaminated wastes that may be generated in the JAERI's PT cycle. The volume of high-level waste after partitioning was about a third that of non-partitioned vitrified waste form. The required repository area was about sixth, which implies increase in capacity of geologic repositories.

J-PARC Transmutation Experimental Facility Program

Maekawa, Fujio

no journal, , 

The partitioning and transmutation (P-T) technology is for volume reduction and mitigation of degree of harmfulness of high-level radioactive waste. JAEA is promoting development of the P-T technology by using an accelerator driven system (ADS). To facilitate the development, construction of J-PARC Transmutation Experimental Facility (TEF) is under planning. The ADS-based P-T technology and TEF program will be outlined.

Status of transmutation technology and ADS in Japan

Okajima, Shigeaki

no journal, , 

The previous presentation related to the title was carried out at the TCADS-1 in 2010 in Karlsruhe. In FY2008, Atomic Energy Commission (AEC) of Japan conducted Check and Review on Partitioning and Transmutation (P-T) technologies. The results of it were shown in the presentation. Since then the situation of the nuclear energy development policy in Japan has changed. One of the main reasons of the change was Fukushima Daiichi Nuclear Power Plant Accidents which were induced by the Great East Japan Earthquake and the following tsunami in 2011. The status of the nuclear energy development took on a different posture in Japan. This time the status of it, including the latest strategic energy plan issued by Government of Japan, and the on-going programs in Japan concerning to the P-T technologies will be presented. And the state-of-the-art not only in the development of the P-T technologies and but also in the development of ADS technologies will be also shown.

PSi project for Accelerator-Driven System

Nishihara, Kenji; Sugawara, Takanori; Tsujimoto, Kazufumi

no journal, , 

Japan Atomic Energy Agency has reorganized past R&Ds and launched PSi project (PSi: Proton accelerator-driven Subcritical virtual system) for R&D on ADS (Accelerator-Driven System). The PSi project aims efficient R&D toward industrialization of partitioning and transmutation by Accelerator-Driven System (ADS) by constructing "virtual" ADS on computer. The project is planed for around 10 years and final goal is to be ready for final design and approval application of demo-scale ADS. The project consists of four R&D fields: reactor physics and nuclear data, ADS plant and safety, lead-bismuth eutectic (LBE) and material, and, accelerator. Each field includes computation code for efficient engineering design, construction of model assembled in the code, and experiments to verify and validate the model. The experiment is not large-scale mock-up but small one using existing facility in Japan and the world.
