    摘要： Low temperature water in a low temperature water tank 12 installed outside a reactor pressure vessel 9 is pumped by a high pressure pump 15 and supplied through a conductor 17 under pressure. The supplied water is ejected, as a stream of cold water jet 8, from a nozzle 14 connected to the conductor 17 and introduced into the reactor pressure vessel 9 by a driving mechanism. The stream of cold water jet 8 ejected from the nozzle 14 is directed to impinge against a predetermined position of a core shroud 13 in reactor water 11 filled in the reactor pressure vessel 9 and being at temperature higher than the low temperature water. Then, while continuing to eject the cold water jet 8 from the nozzle 14, the nozzle 14 is moved away from the predetermined position, or the ejection of the cold water jet 8 from the nozzle 14 is stopped, allowing the predetermined position to be heated again with the temperature of the reactor water 11. A thermal shock is thereby applied to the predetermined position for improvement in residual stress of the core shroud 13.

    摘要： In a digital-to-analog converter including a plurality of constant current sources, a plurality of first current switch elements connected between the constant sources and a first output terminal, and a plurality of second current switch elements connected between the constant current sources and a second output terminal, a reference voltage of the constant current sources is generated by an operational amplifier. The operational amplifier is disabled in response to a current control signal to turn OFF all the constant current sources.

    摘要： A method and apparatus for inspecting the change in a water quality in terms of the change in a corrosion rate by detecting the capacity change between opposed electrodes due to the corrosion of electrode surfaces. As a result, the water quality can be continuously monitored over a long time while leaving the electrodes in the water to be inspected. Thus, the method and apparatus are suited for controlling the water quality especially in an atomic reactor vessel.

    摘要： A preparatory molding roll 4 having a convex push surface 41 is pushed to an outer peripheral surface of a work 1A while the work 1A is chucked by a pair of molds 2 and 3 and is rotated by applying axial propelling force, to bend inward the outer peripheral surface of the work in a radial direction. The work is then chucked by the preparatory molding roll and the upper and lower molds. Next, the preparatory molding roll is moved back and the work is crushed in the axial direction to form a bent portion 1a. A molding roll 5 is pushed to mold the outer shape of the work. A grooved roll 6 is next pushed to the outer peripheral surface of the work and a groove 1b is formed on the outer peripheral surface.

    摘要： A system of preventive maintenance for plant component parts correlates parameters for determining the transition probability distribution of degradation phenomena, selects an arbitrary influencing factor with respect to each of various influencing factors of the degradation phenomena, selects one of the parameters for the transition probability distribution as a first function, and sets the transition probability distribution when the variables of various influencing factors are reference degree values of a reference system. The system computes a ratio between the first function and the parameter value in the reference system to give a function of the subdivided index of degradation of the influencing factor, multiplies the subdivided index of degradation of various influencing factors by a unit conversion and a coefficient for reliability.
