  • Patent number: 7782994
    Abstract: This invention relates to an inhibitor of lead-induced stress corrosion cracking including nickel boride in the secondary side of steam generator tubes in nuclear power plants and an inhibition method using the same, and more particularly, to an inhibitor of lead-induced stress corrosion cracking, in which nickel boride is added to secondary side cooling water of the steam generator in an amount of 0.2˜6 g/l, and to an inhibition method using the same. According to this invention, when the inhibitor of lead-induced stress corrosion cracking is added to the secondary side of the steam generator tube in nuclear power plants, stress corrosion cracking of the tubes, which occurs in the lead-containing neutral or caustic solution, and a crack growth rate are decreased, thus increasing elongation. Further, a stress corrosion cracking ratio is decreased, and therefore the stress corrosion cracking resistance of metal or alloy can be improved.

  • Patent number: 7603869
    Abstract: The present invention relates to a refrigerator having a dispenser. In the present invention, the dispenser is provided in a concave portion of a door to be exposed toward a front surface of the door. A water tank is installed between a rear surface of the dispenser and a door liner defining a rear surface of the door. The water tank stores the water delivered from an external water supply source while the water in maintained at a relatively low temperature and then discharges the water to the outside through the dispenser. Furthermore, in the present invention, a nozzle, through which the water is discharged from the water tank, is directly connected to a drainpipe of the dispenser, so that users may always take out the water maintained at a constant temperature.
