Abstract: A blind nut tool has spaced arms, one to extend on either side of a drywell head flange. The arms are mounted on a U-shaped channel member and the lower arm holds and retains a nut and washer pair on the underside of the flange as it is torqued on a threaded stud extending through the flange.

Abstract: Apparatus for assembling fasteners includes a fastening wrench operated by a first operator and having interchangeable sockets of different sizes for engaging nuts of different sizes. The nuts are required to be tightened to different torque values on their respective bolts. When the first operator removes a socket from a socket tray in preparation for attaching the socket to the fastening wrench, a signal is sent to a controller which determines the torque value associated with that socket size. When the fastening wrench reaches the specified torque value during the tightening operation, the controller automatically shuts the fastening wrench off. The apparatus also includes a second wrench, operated by a second operator, for engaging the heads of the bolts to prevent them from turning during the tightening process. During the tightening process the second operator may not be in communication with the first operator.

Abstract: A nut runner tool is used to engage, turn, capture and lift the RPV head closure nuts from the RPV studs. The tool is also used to capture, lift and transport the nuts from the storage tray to the RPV head closure studs. The nut runner system enables a single operator to remove and install head closure nuts quickly and safely. The nut runner is powered by a remotely operated air driver. The reaction torque is transferred safely through the tool into the top of the closure stud. The air driver unthreads the nut, then a nut holding device is actuated, and the nut and tool are lifted from the top of the stud with a hoist attached to a trolley. The nut and tool are moved radially from the stud location to the storage position in the nut rack. When positioned over the storage location, the lowering of the nut into the rack is performed by the hoist, eliminating the need to manhandle the nuts into and out of the storage rack.

Abstract: A barrel lock includes a cylindrical plug with a locking ball actuated by a positive acting threaded pin that is screwed into the plug. The plug slips into a mating cylindrical retainer and is locked in place by the pin forcing the ball to protrude beyond tile exterior of the cylindrical plug. An anti-rotation coupling that includes a key attaches to the plug which makes the barrel lock especially easy to install and operate. A threaded puller assures separation of the plug and retainer even when the barrel lock may be jammed due to earlier tampering. The simplicity of the invention provides for a rugged construction with positive sealing surfaces that protect against contaminants and corrosion.
