Abstract: Disclosed herein is a method of preventing corrosion degradation in a defective region including an expansion transition region and/or an expansion region of a heat transfer tube of a steam generator in a nuclear power plant by using nickel (Ni) plating or nickel (Ni) alloy plating. The method can prevent various types of corrosion damage, such as pitting corrosion, abrasion, stress corrosion cracking, lead-induced stress corrosion cracking and the like, occurring during the operation of the steam generator, and particularly, pitting corrosion or primary and secondary stress corrosion cracking, so that the life span of the steam generator is increased, maintenance costs are reduced, and the operation rate of a nuclear power plant is increased, with the result that the unit cost of the production of electric power can be decreased, thereby improving economic efficiency.

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.

Abstract: In a method of setting recipes of a defect test, a laser intensity map of a sample is obtained. The laser intensity map is then area-scanned to obtain average laser intensity. Recipes are set based on the average laser intensity. Thus, a laser power set in a defect detector may be constant regardless of inspectors so that the defect detector may have improved defect detection reliability.

Abstract: In a method of inspecting defects, a first actual region of an actual object is inspected based on a first characteristic parameter as an inspection condition. A point where an inspection region of the actual object is changed into a second actual region from the first actual region is determined. The second actual region is then inspected based on a second characteristic parameter as the inspection condition. The first and second parameters may include contrast of a light that is reflected from a reference object, intensity of the light, brightness of the light, a size of a minute structure on the reference object, etc. The characteristic parameters of each reference region on the reference object are set. Thus, the defects may be accurately classified so that a time and a cost for reviewing the defects may be markedly reduced.

Abstract: A method of registering a reference image includes obtaining information of layers in a design pattern that is used for forming an actual pattern on a substrate and comparing the information to obtain a difference therebetween. The method further includes obtaining a reference image for testing the actual pattern based on the difference. Thus, the reference image, which is obtained from the design pattern, but not from the actual pattern, may include information on all of the actual patterns on the substrate.

Abstract: In a method and an apparatus for inspecting a wafer surface, a wafer is loaded into a chamber. An incident light including a first light for sensing a vertical position of the wafer and a second light for inspecting the wafer surface is irradiated onto the wafer. The first light is reflected on an inspection region or a next inspection region of the wafer and is detected to control a wafer position. The second light is scattered on the inspection region and is detected to inspect the wafer surface of the inspection region. Position information of a wafer is examined and a position of the wafer is adjusted before inspecting a surface of inspection region of a wafer so as to enable accurate inspection of the wafer surface.

Reflectivity of each of the plurality of regions is obtained. Amplification ratio for each region is determined using the reflectivity. A light is irradiated onto the regions. A light reflected from a first region is amplified by a first amplification ratio that is determined for the first region. Moving the irradiated light from the first region to a second region is detected. A light reflected from the second region is amplified by a second amplification ratio that is determined for the second region. The amplified lights from the first region and the second region are analyzed to determine an existence of a defect on the object.

Abstract: The present invention relates to a method for inhibiting stress corrosion cracking occurring on steam generator tubes in the secondary side of nuclear power plants and an inhibitor therefor. The method comprises supplying lanthanum boride as an inhibitor for stress corrosion cracking into the secondary feed water of the nuclear power plants. The method according to the present invention improves the resistance of stress corrosion cracking ten times or higher than no inhibitor, and five times or higher than the conventional inhibitor. In particular, the method according to the present invention shows a superior inhibiting effect in the lead-contaminated environment such that the complete inhibition of stress corrosion cracking can be achieved. As thus, the method can reduce the unexpected stop of operating nuclear power plants caused by the stress corrosion cracking on steam generator tubes, thereby reducing the cost required for maintaining and repairing the tubes.

Abstract: Disclosed is a method of electroplating a Ni—Fe—P alloy using a sulfamate solution and, in particular, a method of electroplating a Ni—Fe—P alloy using a plating solution containing nickel sulfamate, iron sulfamate, phosphorous acid, and a buffer agent. The method is advantageous in that a residual stress of a deposited layer is very low and has stable mechanical properties, and excellent thermal and corrosion resistance because the deposited layer is obtained by electroplating the Ni—Fe—P alloy using the sulfamate solution useful in a high rate plating process. Furthermore, the method can be applied to various parent metals such as stainless steel, Inconel and iron alloys, and to various fields because the chemical compositions of the deposited layer are readily controlled by varying the concentration of the plating solution.
