摘要： A gas supply apparatus of the present invention includes a gas discharge line of a first electromagnetic valve having s a switching valve placed therein, and a second electromagnetic valve placed between the switching valve and a gas supply source. The switching valve switches between a gas discharge from the first electromagnetic valve and a gas supply to the first electromagnetic valve. At the time of a normal operation, the second electromagnetic valve opens a gas discharge line side and closes a switching valve side, and when the power source is lost, the second electromagnetic valve opens the switching valve side and closes the gas discharge line side. In this way, even when the power source is lost, an operating valve can not only be operated remotely but also be operated safely by a remote operator.

摘要： A flow-path forming gasket is interposed between peripheries of each adjacent ones of stacked heat transfer plates; communicating-path forming gaskets are each installed, surrounding the passage holes in each adjacent ones of the heat transfer plates alternately; and thereby a first flow path adapted to pass a high-temperature fluid, a second flow path adapted to pass a low-temperature fluid, and communicating paths adapted to cause the fluids, respectively, to flow in and out of the first and second flow paths are formed alternately on opposite sides of each heat transfer plate. A drain hole is formed in each of the heat transfer plates to discharge fluid leaking from the first flow path, the second flow path, or the communicating path. The drain hole is surrounded by gaskets isolated from the first flow path, the second flow path, or the communicating path. A leakage flow path or a leakage collector is formed by the gaskets.

摘要： A jet pump beam (hereinafter, referred to as a beam) is fitted into a pair of projecting portions installed to a transition piece, and after the beam is arched, a beam bolt engaged with the beam is tightened. An end of the beam bolt comes in contact with a top surface of an insert member fitted into an elbow disposed between the pair of projecting portions. An ultrasonic sensor head is fixed to the beam bolt, and ultrasonic waves are sent to the beam bolt from the ultrasonic sensor in the ultrasonic sensor head. An ultrasonic measuring apparatus obtains echo intensity of each of reflected waves generated at the end of the beam bolt and a bottom surface of the insert member, and based on the echo intensities, an echo intensity ratio R is calculated. The installed state of the beam is checked using the echo intensity ratio R.

摘要： A gamma scanning apparatus includes a moving and fixing mechanism which moves/fixes a housing to a definite position, and a rotating and moving mechanism which moves a fuel assembly vertically in addition to rotating the assembly. A gamma-ray counting circuit measures an output of a gamma-ray detector, and a data collecting/analyzing and controlling apparatus analyzes data output from the gamma-ray counting circuit, in association with data relating to the rotation and movement of the fuel assembly by the rotating and moving mechanism. The rotating and moving mechanism, after fixing the vertical position of the fuel assembly with the housing also fixed, rotates the fuel assembly through 360° with its height kept constant, and during the 360° rotation of the fuel assembly, the gamma-ray counting circuit measures either a time average of count values of the detector during the rotation or an integral value within a fixed time.

摘要： An electrochemical corrosion potential sensor has a sensor unit, a lead wire and a quasi-reference electrode. A sensor unit includes a tube-shaped insulator, a tube-shaped metal casing joined to an end portion of the insulator, and a Pt electrode joined to another end portion of the insulator. A lead wire connected to the Pt electrode passes through the insulator and the metal casing. The quasi-reference electrode disposed in the metal casing is made of a less noble metal and electrically connected with the lead wire.Since an electrochemical corrosion potential sensor has the quasi-reference electrode, the measurement of the corrosion potential of a structural member of a nuclear power plant and an abnormality occurrence (water intrusion) can be accurately detected during the operation of a nuclear power plant.
