|20140150228||MACHINING, EXAMINATION, AND WELDING INTEGRAL DEVICE FOR NOZZLE - The present invention relates to a machining, examination, and welding integral device for a nozzle, and more particularly, to a machining, examination, and welding integral device for a nozzle in which machining, examination, and welding can be made in the nozzle by one device. To this end, there is provided a machining, examination, and welding integral device for a nozzle including: a pair of caps provided to be separated from each other; a welding unit provided between the pair of caps to weld a junction part of the nozzle and a pipe; a examination unit coupled to one side of the welding unit to check whether the junction part is defective; and a machining unit coupled to the top of the welding unit to remove the surface of a welded portion of the junction part and/or process the welded portion of the junction part.||06-05-2014|
|20100095748||NON-DESTRUCTIVE TEST APPARATUS - The present invention provides a non-destructive test apparatus which can be applied not only to a structure in dry conditions but also to a structure constructed under water or in a location to which it is difficult for a worker to gain access. The non-destructive test apparatus includes a support frame which is disposed adjacent to the target structure and has a vertical guide rail, and a vacuum box which moves upwards or downwards along the guide rail of the support frame. The vacuum box is attached to the target structure and creates a vacuum therein. The non-destructive test apparatus further includes a hoist which is provided on the upper end of the support frame to move the vacuum box upwards or downwards, a fastening unit which fastens the support frame and the vacuum box to the target structure, and a vacuum pump which creates a vacuum in the vacuum box. The non-destructive test apparatus further includes a defect detecting unit which measures a strength of vacuum in the vacuum box to determine whether the target structure is defective, and a control unit which controls the elements.||04-22-2010|
|20090154635||DRAINAGE APPARATUS AND DRAINAGE METHOD FOR REACTOR COOLANT SYSTEM - A drainage apparatus and a drainage method for a reactor coolant system are disclosed. According to the drainage apparatus and the drainage method, the gravity drainage procedure for performing the decomposition maintenance of a main valve forming the pressure boundary part between the RCS and the safety injection system is improved by a forced drainage procedure using a drainage pump, and there are the effects that working period for a planned preventive maintenance is shortened, liquid waste of a coolant of the reactor is not generated, reprocessing costs are decreased, and the economical efficiency and the safety of the nuclear power plant are improved.||06-18-2009|
