Abstract: A pin which projects downwards from an upper core plate (3) of a water-cooled nuclear reactor and is designed to locate the upper end (30) of a fuel assembly is replaced, if damaged, with the plate (3) removed from the reactor and submerged in a cooling pond, using remote-controlled equipment to cut out the old pin, widen the lower part of through hole (10) and insert a new pin (26). The new pin comprises a downwardly projecting part (28), to locate the fuel assembly, and an upper part including a wide portion (34), locating in the widened part of hole (10), and a threaded shaft extending through the plate to engage a retaining nut (29).

Abstract: The process comprises creating a heterogeneous weld (12) and applying a thick layer (14) of a nickel-based alloy to the inner surfaces of both pipe ends, extending axially along them, by means of a build-up weld. The thick layer covers the inner surface of the weld (12), protecting the bi-metallic joint between the two tubes.

IPC: G21C17/00 , G21C5/06

Abstract: The procedure consists of applying a shock to the centering pin (3) and registering the delayed signal from the shock detected by a vibration sensor (25) located close to the pin. The signal delivered by the sensor is processed and analyses in a Fourier series, and a frequency corresponding to the maximum value of the response spectrum is selected and compared with a reference value to determined whether the pin is properly locked. The apparatus used for the procedure includes a system for lowering a frame (11) with a supporting plate (12) into the water, a swinging hammer (16), a positioning system (26, 35, 36, 37) for the vibration detector. a hammer actuating mechanism (20, 21, 22), and signal registering and processing systems.

IPC: G21C19/20 , G21C19/32 , G21C19/00 , G21C19/26

Abstract: The process, for use on a pressurized water reactor (PWR) that is shut down and cool, comprises raising the core top plate (4a) with lifting and handling equipment in a pond above the core vessel (1). When a fuel assembly remains attached to the top plate, a fuel assembly holder (22) is lowered into a position where it holds the fuel assembly onto the top plate while it is transferred to a receiver (15) within the pond. The holder is then released, and the fuel assembly is deposited in the receiver, if necessary after cutting its centering pin.

IPC: G21C13/036 , G21C7/12

Abstract: An adapter (1), which passes through an aperture (3) in the cover (4) of a nuclear reactor vessel, is repaired by cutting through the welded joint (7) between the adapter coupling (6) and sleeve (2), machining a chamfered edge on the upper end of the sleeve, applying a new adapter with a chamfered coupling edge, and re-welding the components together by filling the chamfers with metal. The position of the adapter is monitored before and after welding.
