Zusammenfassung:	An apparatus (600) configured to structurally replace a cracked weld (302c) in a nuclear plant (300) may include: a first body portion (602) that includes a first gripping portion(610); a second body portion (604) that includes a second gripping portion (612); a wedge portion (606) between the first and second body portions; and/or an adjustment portion (608). The first body portion may be configured to slidably engage the second body portion. The wedge portion may be configured to exert force on the slidably engaged first and second body portions. The adjustment portion may be configured to increase or decrease the force exerted by the wedge portion on the slidably engaged first and second body portions. When the adjustment portion increases the force exerted by the wedge portion on the slidably engaged first and second body portions, a distance between the first and second gripping portions may decrease.
