摘要： An imaging material providing device of the present invention comprises: means for carrying imaging material particles charged to a first polarity, the imaging material carrying means having a portion formed of elastic material for holding the imaging material particles; means for receiving imaging material particles, the imaging material carrying means being disposed apart from the imaging material carrying means with a gap therebetween and being charged to a second polarity opposite to the first polarity so that the imaging material particles may be electrostatically attached onto the imaging material receiving means; means for elastically deforming the elastic portion of the carrying means, the imaging material particles being introduced into the gap when the deformed elastic portion is restored; and means for generating an electric field in the gap and electrostatically attracting the charged imaging material particles in a direction toward the imaging material receiving means.

摘要： A fuel assembly for a nuclear reactor comprises a fuel bundle in which a number of fuel rods are regularly arranged and a channel box surrounding the outer periphery of the fuel bundle. The interior of the channel box is designed so that the inner cross sectional area of the channel box increases from the upstream side of the coolant flow towards the downstream side thereof, for example, by stepwisely shaving the inner surface of the channel box. The corner portions of the channel box may be chamfered to improve the stress due to the inner pressure.
