The deuterium retention property of B4C converted graphite and isotropic graphite exposed to DIII-D deuterium plasma was examined by using a technique of thermal desorption spectroscopy. Major outgassing species were HD, D2 and CD4 in both the graphi

In JT-60U, the modification to a W-shaped pumped divertor will be completed in May 1997, aiming to realize sufficient reduction in heat flux to the targets and good H-mode confinement simultaneously. W-shaped geometry is optimized not only for formin

A possible mechanism of the crack formation observed in the cooling channels of the toroidal field (TF) coil in JT-60U is investigated. The compressive force (radial direction of the conductor of TF coil) on the cooling channel can produce localised

Since 1992, the boronization using B10H14 (decaborane-based boronization) has been utilized in JT-60 once or twice a year. It is very effective in reducing both the impurities, like oxygen and carbon, in the plasma and in recycling fuel particles. Ho
