摘要： PURPOSE:To analyze and measure respective separated component gases using a Raman scattering spectroscope by separating isotope gas into respective isotope gases using a high temp. column for gas chromatography. CONSTITUTION:A part of the component gas flowing through process piping 1 is sampled through a branch pipe 18 together with the carrier gas from a carrier gas supply tank 2 and a definite amount of said gas is sampled by a sampling pipe 3 to be allowed to flow to a separation column 4 packed with a molecular sieve. For example, the hydrogen isotope and methane isotope separated by the column 4 are detected by a heat conductivity type detector 6. When the presence of hydrogen gas is detected, the respective separated gases are sampled. Next, gas cells 71, 72 are irradiated with the laser beam from argon ion laser 8 through irradiation windows and the scattering beams 9 from the gases in the cells are incident to a Raman scattering spectroscope 10 and spectrally analyzed to measure Raman scattering beams. By this method, the concns. of respective hydrogen isotope gases can be measured from the intensity of the spectrum peak of the hydrogen isotope gas of the gas cell 71.

摘要： PURPOSE:To provide a simple and compact tritium-containing gas processor for purifying a large amount of gas containing tritium. CONSTITUTION:By sending contamination gas generated in a room 1 placed with a tritium treatment component to an oxidation catalyst tower 5, tritium is converted to water. Then water is recovered with a water absorbing dryer tower 1 filled with water absorbing high polymer and cooled inside, or passed through a water-absorbing dryer tower 77 added with drying material for backup and only pure gas is discharged through an exhaust stuck 8 to the air. The water absorbing dryer tower 77 is put by water absorbing high polymer material 12 of rapid water absorbing rate near the inlet and water absorbing high polymer material 13 with large water absorbing capacity in the behind and finally by a solid drying material for almost completely eliminating water. Also, to reduce the load of the water absorbing dryer tower 7, a condenser for primarily recovering water is arranged in front and a condenser setting water-absorbing high polymer material is placed at a cooling plate in the behind.

摘要： PURPOSE:To obtain a blanket of a nuclear fusion reactor in which the influence to the heat transfer property owing to a thermal deformation can be reduced, the structure is simple, and the manufacture is easy. CONSTITUTION:A cooling material 3 of a blanket, and either a tritium breeding material 4 or a nutron doubling material 6 are filled in a blanket container 1, pipes in which a material other than the above materials is filled are installed in the blanket container 1, and furthermore, a structure in which the nutron doubling material 6 is placed between the cooling material 3 and the tritium beeding material 4 is adapted. The product is cooled through a specific thickness of nutron doubling material 6, and a temperature difference between the temperatures of the cooling material 3 and the tritium breeding material 4 has been obtained, and even though the thickness of the nutron doubling material 6 is changed owing to a thermal deformation, the influence to the heat transfer property is small. Since the blanket is composed as an assembly of pin type pipe group of duplex pipes at the best, the manufacture is easy.

摘要： PURPOSE:To recover leakage tritium gas in a room by the use of an inexpensive material and furthermore miniaturize and simplify the whole process. CONSTITUTION:Contaminated gas exhausted from a room 10 in which a tritium process device is set is allowed to previously flow through an oxidation metal packed column 3 for packing metal oxidized in the condition of oxygen oversaturation and tritium is changed into water molecules by the use of the metal reduction action of hydrogen tritium. Thereafter moisture is recovered by a drier 5, clean air alone is released from an air outlet 6. An oxygen source supply device 7 for previously oxidizing the metal, a hydrogen gas supply device 8 for adding for heightening a rate of recovery of tritium and heaters 11, 12, 13 are equipped. After the moisture absorbed in the drier 5 is evaporated by heating, dewing is recovered by a cooler 4.
