Abstract: The laser beam welding of a spacer grid assembly is accomplished by dividing a laser beam (21) into at least two beam segments (37). These beam segments (37) are then routed around the mixing vanes (31) and focused below the vanes (31). The focus and coincidence (34) of the beam segments (37) may be moved down along the intersection to provide an elongated smaller diameter weld. The spacer grid assembly of the present invention has an improved Departure from Nucleate Boiling performance, increased strength against buckling, and a reduced detrimental effect on the coolant flow.

Abstract: The method comprises joining a cope (19) and drag (20) to form a mold flask (15) having a horizontal parting plane (21) which passes through a pouring cavity (39) in the flask, tilting the flask so that the parting plane is vertical and the pouring cavity is at the vertically upper end of the flask and, while the flask is vertical, pouring molten metal through the cavity to fill the flask mold. Each filled flask is maintained in the vertical orientation until the molten metal cools. After the metal cools, the flask is tilted until the parting plane is horizontal, before the cope is detached from the drag and the cast part removed. Preferably, at least two flasks are arranged on a single pallet with their parting planes oriented vertically. The preferred drag has a drag outer flange (29) and a parting line flange (37), and the cope has an outer flange (23) and a cope parting line flange (27). The parting line on the drag and the parting line on the cope include respective notches (38, 28) for defining the pouring cavity.

Abstract: A tool (10) for creating a standard repeatable impact on a nuclear steam supply system (NSSS) structure to determine the response of an accelerometer to the impact of a known energy at a predetermined location on the structure. The tool (10) includes a barrel (12) and a spring (30) which biases a ram (20) reciprocally mounted in the barrel and driven by cam plates (66 and 68) on shaft (60). A flange (28) on ram (20) compresses spring (30) and upon movement of follower (72) to a maximum radial distance from shaft (60), the follower (72) drops down step (70) on the cam surface to allow spring (30) to uncompress and project ram (20) out of the barrel such that end (22) of the ram creates a standard impact on the NSSS structure. A hand crank drives shaft (60). A dampening spring (78) assists in the rebound of the ram (20).

Abstract: A register system is provided for making molds for metal casting which reduces flaws attributable to parting line shift. This is accomplished by urging the cope mold flask (11) against two fixed stops (50, 52) on the long axis, and one fixed stop (54) on the short axis of the flask. This same register principle is applied in the drag mold making station (18), where the drag flask (15) is urged against two fixed stops (100, 102) on the long axis, and one fixed stop (90) on the short axis of the flask. At the closer station (24), where the mold halves are assembled using the improved closer (150) which comprises in an assembly of cooperative association an upper support framework (160), an intermediate support framework (170) suspended from the upper support framework (160) as so to permit only pure vertical motion therebetween, a cope capture framework (180) freely suspended from the intermediate support framework (170), and a drag capture framework (190) which is suspended from the cope capture framework (180) so as to permit only pure axial translation therebetween. The flasks are properly aligned to the patterns at the mold making stations, and again properly aligned to each other at the closer station, so as to eliminate parting line shift problems of the mold halves.
