In the future fusion reactor, dust control may become more important f
or safety, than for existing fusion facilities. Some estimations show
more than hundreds kg/yr dust will be generated from the plasma facing
materials in the vacuum vessel. If we consider continuously operating
plant, dust should be monitored aid removed during the operation time
. Optical monitoring methods and electrostatic removal methods are use
ful approaches to accomplish this. An investigation of the development
of the dust removal system for a fusion reactor is reported in this p
aper.
