摘要： An electron discharge machining tool (EDM) (10) for removal of conductive material from a workpiece such as a plug (28) in a nuclear steam generator tube (26) is an end effector connected to a remotely operated manipulator arm by a mount 56. A piston (47) drives a hollow conductive rod (44) with a graphite electrode cutter 30 in reciprocating motion through receptacle (14) having a restrictive drain (37) and containing deionized water. The reciprocation of rod (44) is controlled by power supply (50) sensing the electrical potential and signalling Mooz valve 48 which controls hydraulic flow in conduits 54a and 54b communicated to opposite sides of piston (47). A TV camera 32 monitors the operation.

摘要： Système de repérage permettant la fabrication de moules destinés au coulage de métaux, réduisant les défauts imputables au décalage de la ligne de joint. On parvient à cela en poussant le châssis (11) de moulage du cadre supérieur contre deux butées fixes (50, 52) sur l'axe long, et une butée fixe (54) sur l'axe court du châssis. Ce même principe de repérage est appliqué dans le poste (18) de fabrication du moule du châssis inférieur, où l'on pousse ledit châssis inférieur (15) contre deux butées fixes (100, 102) sur l'axe long, et une butée fixe (90) sur l'axe court du châssis. Les moitiés de moule sont assemblées au poste de fermeture (24) au moyen du dispositif amélioré de fermeture (150), qui comprend un cadre (160) supérieur de support, un cadre (170) intermédiaire de support suspendu au cadre (160) supérieur de support de manièe à ne permettre qu'un mouvement vertical pur entre ceux-ci, un cadre (180) supérieur de capture librement suspendu au cadre (170) intermédiaire de support, ainsi qu'un cadre (190) de châssis inférieur de capture suspendu au cadre (180) supérieur de capture, de manière à ne permettre qu'une translation axiale pure entre ceux-ci. Les châssis sont correctement alignés sur les modèles, aux postes de fabrication des moules, et à nouveaux correctement alignés les uns par rapport aux autres au poste du dispositif de fermeture, de manière à éliminer les problèmes de décalage de ligne de joint des moitiés de moule.

摘要： A method of repairing leaky compression fitting seal joints between a pressure stub tube (22) projecting from a nuclear reactor head (12) and a cylindrical thermocouple body (24) concentrically mounted in the stub tube (22) for penetration of the reactor pressure boundary. The method includes the steps of loosening and disassembling compression fitting nuts (30,32) and fitting body (34) to expose, and remove by grinding, a cammed ferrule radial compression means (26,28), cleaning the surfaces to be sealed, axially telescoping a split collar (40) between the tube (22) and the thermocouple body (24) and providing split rings (44,46) of brazing material surrounding the thermocouple body adjacent the exposed ends of the tube (22) and the collar (40). Resistance heating the tube and, therefore, the brazing material and repositioning and reassembling the fitting body (22) and fitting nuts (30,32) to complete the repaired seal joint.

摘要： A nuclear fuel support grid 10′ of egg-crate structure has wave defining strips 12a, 12b, 12c 12d defined by bends 16′ inclined from the vertical and opposing cantilevered springs 18′ with inclined spring bases 20′ opposing them for support of fuel rods 22 intermediate their ends. The "inclined waves" defined by inclined surfaces formed by bends 16, and spring bases 20′ of cantilevered springs 18′ provide lateral components to the coolant flow in patterns which enhance DNB and corrosion behavior.

摘要： A wear-reduction-shield (40) for use between the core plate (24) and lower end fitting (26) of a pressurized water reactor (10) to reduce excessive wear of in-core-instrumentation thimbles (30) due to flow induced vibrations and resist fuel assembly tipping has a cylindrical body portion 42, with core plate engaging lower end surface (44). At the opposite and upper end, a tapered internal end wall (46) assists upward threading of the monitor and cable. On the outside of the upper end symmetrical leg portions (52) and central land (54) surround a thimble (30) receiving opening (48). Smoothly tapering outer surface (56) minimizes turbulence in and beyond opening (34) in lower end fitting (26). Internal dimensions of shield (40) avoid structure such as sleeve (50) which may be present.

摘要： A system and method for installing a nozzle dam unit (26) in a nuclear steam generator having a head (12) including a head internal surface, a manway (14) penetrating the head, and a nozzle (16) penetrating the head. The system comprises a manipulator (76) adapted to be passed through the manway and having one end (82) adapted to be attached remotely to the head internal surface and a free end including a clamp member (104). A plurality of nozzle dam segments (52, 54, 56) are each sized to pass through the manway and carry means thereon (114, 116) for engaging at least one other segment, the segments when fully engaged to each other forming a dam subassembly sized to pass into and seat against the nozzle. The manipulator is controlled so that the clamp member grasp and supports one of the dam segments within the head until the subassembly is formed within the head, and then is translated within the head until the dam subassembly seats within the nozzle.

摘要： A nuclear fuel rod (10) having a tube (12) of cladding material with an active fuel length of a column of pellets (20) and a plenum having an end cap (16) and containing a coil spring (30) to bias the column of pellets, which spring includes an active region (32) and a self-locking region (36). The active region (32) is of coils smaller than the tube inner diameter and biases the column of pellets (20). The self-locking region (36) coils are larger so that after being inserted in a torqued, reduced diameter condition, they are released and expand to hold the spring in an axial position by engagement with the tube wall. A bight (38) on the end of the self-locking region (36) assists in torquing the coils.

摘要： An orbital weld head tool (10) has an orbiting and reciprocating carriage (22) for movement around a mandrel (12)fixed to a workpiece. Reciprocation is by a ball nut and screw drive means (70,74) driven by an arc voltage controlled motor (64). Rotation of carriage (22) with its ceramic shielded tungsten weld tip (16) and gas conduit (19) is by means of a separate motor (62) and drive belt (28). Power is supplied from a flexible hose connected through a conductive ball bearing assembly (30) and a conductive shoe (20) for weld tip (16) mounted on carriage (22).
