[Example 62] [Title of the Invention] Sealer device for the screw-holes in the flange of the nuclear reactor and the process of its application and removal [Claims] 1. The sealer device (6) for the screw-holes (5) in the flange (4) of the nuclear reactor (1), comprising a lower cover (13) on which bolts (16) are born, an upper cover (12) bearing the bolt holes (17) through which said bolts (16), the nuts (20) screwed onto the said bolts (16), a circular U-grooves (14) placed on the circumferences of said covers (12, 13) and the seal-ring (15) to be placed in the said grooves (14), in which the placement of said covers (12, 13) are adjusted by means of said nuts (20) to deform the configuration of the seal ring (15) in order to seal the vessel. (See Figure 1 and 3) 2. The tool designed to place and remove the sealer device (6) for the screw-holes in the flange of the nuclear reactor described in Claim 1 comprising an outside piping part (28); a relatively ratable inside piping part (27) installed inside of and on the same axis as the said outside piping part (28), multidimensional contours (36, 50) offset placed within, a handle (32) affixed at the opposite end of the inside piping part (27), a stopper (53) to restrict relatively rotating two piping parts (27, 28) affixed at the opposite end of the outside piping part (28). The nut is turned by the relative rotation of said inside piping part (2’) to the outside piping part (28), and the lining up, offset or the spin of the said multidimensional contour. (See Figures 2, 3) [Excerpt from Detail Description of the Invention and Drawings] This invention concerns the placement and removal of the sealing device for screw-holes of the nuclear reactor vessel while inspecting the reactor in order to reduce the exposure to radiation. The water is introduced into the reactor for the purpose, but because the presence of water in the screw-holes is undesirable, they must be sealed off. The invention concerns the sealing device and a tool to apply it prior to inspection or after the inspection is completed. The existing device of which screw holes in the flange of a sealer is sealed is publicly know, but because its structure is complex and some doubts as to its efficacy existed. Figure 1 106
Figure 2 Figure 3 [Explanation] The related invention (Claim 2) is a tool for placement and removal of sealing device on the specified positions on the nuclear reaction vessel and therefore is a device to facilitate the function of the specified invention. They, therefore, constitute the product and a product for handling the product. [Concerned Section] Patent Law Section 37(iii) 107
