SOLUTION: The nuclear fusion reactor is provided with a reaction vessel 2, an inside vessel 3 which is coaxially installed inside the reaction vessel 2, an anode 1 as an ion beam source which is arranged on the central axis line of the inside vessel, a power-supply device 7 connected to the anode, a hydrogen injection device 5 which injects hydrogen gas into the inside vessel 3, a nuclear- fusion-source-material supply and purification device 10 which supplies a liquid nuclear fusion source material into the reaction vessel 2 and which purifies the source material, a porous substance 12 by which the source material supplied into the vessel arranged on the inner circumferential face of the reaction vessel 2 is fluidized by a capillary phenomenon and evacuation devices 8, 9 which take out the hydrogen gas in a space part between the reaction vessel 2 and the inside vessel 3, which remove the vapor of the hydrogen and that of the source material and which recover helium so as to be evacuated. When the source material which is fluidized inside the porous substance is irradiated with an ion beam radially irradiated from the ion beam source, a nonthermal nuclear fusion reaction is induced.

摘要： PROBLEM TO BE SOLVED: To provide a ceramic heat exchanger that provides a high efficiency of heat exchange and further having high structural reliability even in the presence of a high-temperature corrosive fluid such as sulfuric acid.
SOLUTION: In the ceramic heat exchanger, several lines consisting of a plurality of flow lines each are formed in parallel on each ceramics block, and each adjacent pair of flow lines is made into flow lines where fluid A and fluid B flow. The fluid A and the fluid B are caused to flow in each adjacent pair of flow lines as opposite flows to effect heat exchange between the fluid A and the fluid B. In a heat-exchanging part, a plurality of ceramics blocks are stacked via a sealant and are connected integrated together at each end along the direction of stacking by a fastening means comprising an end plate and a tie-rod. A thermal expansion absorbing means for absorbing the axial thermal expansion of the tie-rod is provided on the outer surface of the end plate.
