摘要： A temporary cover is plugged into an open handhole or inspection port in a steam generator or another pressure vessel of a nuclear power plant after bolted covers are removed for maintenance inside the generator or vessel. The temporary cover may be locked to prevent foreign objects from entering the generator or vessel. The cover is vented at inclined angles so that air or gas may pass therethrough but is shielded so that gamma rays, which are the most penetrating type of radiation, are greatly reduced and dispersed away from personnel.

摘要： An apparatus and method for plugging an access hole in a steam generator, having a shell, a wrapper, and an annulus positioned between the shell and the wrapper, includes attaching a plate, having a first mating connection and at least one aperture, to the wrapper of the steam generator. A plug, having a second mating connection and at least one aperture, is positioned within a bore of the plate. The plug is rotated approximately 90.degree. for engaging the first mating connection of the plate with a second mating connection of the plug and for aligning the aperture of the plug with the aperture of the plate. A sleeve, having a bore therethrough and at least one aperture, is positioned on the plug and the aperture of the sleeve is aligned with the apertures of the plate and the plug. A pin is installed in the aligned apertures of the plate, the plug, and the sleeve. A retaining nut is positioned on the plug after installation of the sleeve.
