摘要： PURPOSE:To realize the high precision of welding by making use of the projection welding to eliminate the slip when an electrode is pressed. CONSTITUTION:An end plug W1 to be welded by a movable side electrode 2 and a fixed side electrode 3 and a coated tube W2 are held in a butted, manner, the end part held in a butted manner is surrounded in an air-tight manner, the air sucked from the surrounded butt end part, the prescribed vacuum condition is held in the coated tube, and gaseous He is filled in the vacuum coated tube, and then, the end plug is pressure welded to the coated tube by giving the pressure and the welding current required for the welding to the butt end part to seal gaseous He in the coated tube. When the slip is generated between the electrode and the work during the pressure welding, the displacement by pressure is detected and the charge-starting work is stopped to preliminarily prevent the defective welding.

摘要： PURPOSE:To easily remove the hydrogen generated in a nuclear reactor container by passing the hydrogen in the reactor container generated at the time of the hypothetical accident of an nuclear power plant through a piping and introducing this hydrogen through a gas inlet flow rate regulating valve to a blower. CONSTITUTION:The hydrogen in the reactor container generated at the time of the hypothetical accident of the nuclear power plant is introduced through the piping 16 into the blower 15 by the operation of the blower 15 and is boosted by this blower 15. The hydrogen is sent into a container 19 in which a hydrogen occluding material, such as hydrogen storage alloy or hydrogen adsorbing material, such as zeolite, is stored, to occlude or adsorb the hydrogen in the above-mentioned hydrogen occluding material or hydrogen adsorbing material. There is an effect of suppressing the progression of the reaction as the temp. of the hydrogen occluding alloy, etc., is decreased by an endothermic reaction event of the event of the abrupt release of the gaseous hydrogen by the failure of the container 19. The safety to the leakage of the hydrogen is high.

摘要： PURPOSE: To enable inhibition of leakage of electric current and to improve safety for operator by connecting a heater supporting plate with a heater supporting pipe interposing an insulating material.
CONSTITUTION: A heater supporting device in a recombiner comprises a heater supporting plate 10, a heater supporting pipe 9 for fixing and supporting the plate 10 by a stanchion, both being coupled with interposed insulating material 13, 14. The plate 10 supports a heater element 7 for heating gaseous hydrogen generated in an atomic reactor and sucked by a blower. The heated hydrogen is led to a reactor where it forms water by reacting with oxygen and fed back to the atomic reactor again. By this constitution of the recombiner, the hydrogen concn. in the atomic reactor is held at a fixed value.
