摘要： PROBLEM TO BE SOLVED: To provide a sodium sulfur battery module by which the degradation of a joining part and the corrosive degradation of a positive electrode vessel are hardly caused and high output operation can be performed. SOLUTION: In an Na sulfur battery module by connecting plural Na sulfur batteries containing a negative electrode vessel 2 to house Na, a positive electrode vessel 5 to house a positive electrode mold composed of sulfur or an Na polysulfide and carbon fiber, a solid electrolyte tube 1 to separate a negative electrode and a positive electrode from each other and an insulating member 7 which is connected to the solid electrolyte tube 1 and is joined to the negative electrode vessel 2 and the positive electrode vessel 5, the positive electrode vessel 5 contains a joining body of a cylinder part 51 and a flange part 52, and in a material of the cylinder part 51, a corrosive layer is arranged on a surface of Al or Al allay, and the cylinder part 51 is connected to Al or Al alloy-made bus bar, and in the flange part 52, the flange part 52 and the insulating member 7 are joined together by using stainless steel.

摘要： PROBLEM TO BE SOLVED: To simply provide a sodium-sulfur battery with high reproducibility, high reliability, and long life by forming a positive container with a plate material or a pipe made of a cobalt base alloy on which chromium carbide is deposited by adding chromium and carbon. SOLUTION: Molten sodium polysulfide 5 is filled in a positive container 2, and molten sulfur 6 is filled in a solid electrolyte chamber 1 and a negative container 3 arranged on the positive container 2 through an insulating ring 4 to obtain a sodium-sulfur battery. As the material of the positive container 2, a plate material or pipe made of a Co base alloy on which the carbide of Cr is deposited by adding Cr and C is used. The Cr base alloy contains 30wt.% or more Co, 18-28% Cr, and 0.05-0.2% C, and preferably contains W, Mo, Ni, Fe, Si, Mn, La or the like if necessary. The Co base alloy having this composition is heat treated at 500-1000 deg.C for at least 10 hours to deposit a carbide containing at least Cr, having a particle size of 5μm or less.

摘要： PURPOSE: To prevent performance deterioration caused by scattering of a leaked active material and short circuit by dividing a plurality of equipotential batteries in blocks with partitions and making spaces between battery containers insulating or conducting. CONSTITUTION: A plurality of batteries each having an insulating or conducting container are partitioned with insulating partitions, which are brought into contact with the batteries, in blocks. They are housed in a battery module housing container 21 to form a battery module. An active material leaked from a broken battery is retained on the inside of the housing container 21 or the partition 2 and flow out or scattering to the outside is prevented, and the generation of short circuit caused by the leaked active material is reduced. Reliability and safety are enhanced.

摘要： PURPOSE:To provide a temperature control type material irradiation device to maintain the radiation temperature of an irradiation sample set in a reactor core at a constant level at the time of variation of reactor core output. CONSTITUTION:This is constituted of an inner cylindrical pipe 6 furnished with a piping to let sodium flow in and out of the piping by way holding an irradiation sample 7 and an outer cylindrical pipe 4 furnished with a piping storing the inner cylindrical pipe 6 with a gas gap 5 and to let cooling gas filled in the gas gap 5 flow in and out of the piping, and the coefficient of thermal expansion of the material of the inner cylindrical pipe 6 is made larger than that of the outer cylindrical pipe 4. As temperature change of the gas gap 5 controls refrigeration and compensates temperature change of the irradiation sample 7 at the time of variation of reactor core output, it is possible to maintain the temperature of a constantly irradiated sample to a roughly constant level without any time lag.
