JAEA has worked for the contribution to the world disarmament and nonproliferation through the United States and Russia cooperation on the excess weapon plutonium disposition from Russian as well as to acquire the basic data of the post irradiation test with the BN-600 and the vibropack MOX fuel fabrication technologies. To support the initiative of Japan government, JAEA has started the joint research activities with some of the Russian national laboratories under the MINATOM in 1999. Since then, JAEA has been involved into the demonstration experiment for the vibropack fuel irradiation with the BN-600 that was managed by the PESCO corp. under the contract with MEXT. The joint researches with Russian national laboratories and the demonstration studies on vibropac MOX fuel assemblies from 1999 to 2011 are surmmarized in this document.

Proceedings of International Conference on Fast Reactors and Related Fuel Cycles (FR 2009) (CD-ROM), 11 Pages, 2012/00

The paper presents progress results, including fabrication of vibropac MOX fuel pins and 21 FAs for fast reactor BN-600, irradiation parameters and PIE results. It is shown, that no violations of safe operation limits take place. The activities within the framework of the Demonstration experiment is based on the international cooperation and have been performed with the support and participation Russian and Japanese organizations RIAR, IPPE, OKBM, BNPP, MEXT, JAEA, PESCO. The goal of the experiment is to validate possibility of using vibropac MOX FA for weapon plutonium disposition.

The diagnostic system of JT-60U (JT-60upgrade) is composed of about 50 individual diagnostic devices. Recently, the detailed radial profile measurements of plasma parameters have been improved, so that the internal structure of plasmas has been explored. The understanding of plasma confinement has been enhanced by density and temperature fluctuation measurements using a mm-wave reflectometer and electron cyclotron emission measurements respectively. In addition, the real-time control experiments of electron density, neutron yield, radiated power and electron temperature gradient have been carried out successfully by corresponding diagnostic devices. These measurements and the real time control contribute to improving plasma performance. Diagnostic devices for next generation fusion devices such as a CO2 laser interferometer/polarimeter and a CO2 laser collective Thomson scattering system have been developed.
