摘要： PROBLEM TO BE SOLVED: To allow a circuit to select automatically with an optional setting of a power supply voltage by connecting each input to plural input buffers and selecting any of the plural input buffers in response to an output signal from a voltage detection circuit. SOLUTION: An input of an input buffer 2 having a prescribed drive capability with a power supply voltage set to 5V and an input of an input buffer 3 having the same drive capability with a power supply voltage set to 3V are connected to an I/O pad 1. Then an output of the buffer 2 connects to an input e1 and an output of the buffer 3 connects to an input e2 of a 2-input 1-output multiplexer circuit 5. Then an output f1 of a voltage detection circuit 4 providing an output of a digital signal with a level '0' with a power supply voltage set to 5V and providing an output of a digital signal with a level '10' with a power supply voltage set to 3V connects to a selector terminal e5 of the circuit 5. When the circuit 5 receives a level '0' from the circuit 4, the circuit 5 selects the terminal e1 and when the circuit 5 receives a level '1' from the circuit 4, the circuit 5 selects the terminal e2. Then either of the buffers 2, 3 is selected automatically.

摘要： PROBLEM TO BE SOLVED: To improve corrosion resistance of a welding part and hence improve safety and use a member for a nuclear fuel for a long time by welding member for a nuclear fuel, and performing β hardening or α+β hardening to the periphery or the entire member including the welded part. SOLUTION: A process for performing β hardening or α+βhardening to a thermally affected part on welding is provided after a welding process 21. In this case, the hardening, namely the heat treatment, includes the thermally affected part on welding or may be performed to an entire member. Also, a hardening temperature is preferably and approximately 30 deg.C or higher. By providing this sort of heat treatment process, those being localized at the grain boundary of the metal base material crystal particle of a deposit due to the hardening process that is included before welding in the welded part and a thermally influenced part caused by heat input in the welding process 21 are pulverized and uniformly dispersed, thus improving corrosion resistance at the welded part and the thermally influenced part.

摘要： PROBLEM TO BE SOLVED: To improve hydrogen absorption resistance and corrosion resistance under an environment in which hydrogen is injected into reactor water by arranging an excellently hydrogen absorption resistant material in at least a part of a one-phase area of a liquid phase consisting of high temperature water environment on the member surface and arranging an excellently corrosion resistant material in the other place. SOLUTION: In a fuel assembly used for a boiling water reactor, for example, in which hydrogen is injected into reactor water for the purpose of reducing corrosion, a Zr-Nb alloy is used as an especially excellent hydrogen absorption resistant material while a zircaloy alloy is used as an especially excellent corrosion resistant material. For example, a Zr-Nb alloy or the like is used for a spacer 2 arranged in a one-phase area of liquid phase consisting of high temperature water and for a member 6 securing a water flow passage, while a zircaloy alloy or the like is used for a spacer 2 arranged in a two-phase area constructed of a liquid phase consisting of high temperature water and a gas phase, a fuel rod 1, and a channel box 5. In an area having no temperature distribution in the member, an excellently hydrogen absorption resistant material is arranged.
