Filed:

Jun 19, 2000

Appl. No.:

09/596334

Inventors:

Bruce F. Allen - Granby CT
Edward F. Lamoureux - Hampden MA
Brian W. Ring - Roxbury CT

Assignee:

Westinghouse Electric Company LLC - Pittsburgh PA

International Classification:

G21C 332

US Classification:

376437, 376434

Abstract:

Anchor assembly apparatus for improving the structural integrity of a guide tube ( ) in a nuclear fuel bundle ( ). A sleeve ( ) has a proximate end ( ) and a distal end ( ) that is adapted for insertion into a receiving end ( ) of the guide tube. A pin ( ) has a near end ( ) and a far end ( ) adapted for insertion into the sleeve at the sleeves proximate end. The pin has an external surface ( ) that applies a radial force to an inner surface ( ) of the sleeve when the pin is inserted into the sleeve. The force is sufficient to cause a locking surface ( ) on the sleeve to expand radially outward.

Assignee:

WESTINGHOUSE ELECTRIC COMPANY LLC - Cranberry Township PA

International Classification:

G21C 7/16

US Classification:

376230

Abstract:

A control rod drive system for a nuclear reactor that employs hydraulic cylinders to operate a conventional plunger/gripper drive system to incrementally move control rods into and out of the core of a reactor. The pressure differential for driving hydraulic pistons within the cylinders is obtained from the difference in pressure between the outside and inside of the core barrel of the reactor and control of the pistons is obtained from external solenoids attached to the reactor control system. The external solenoids regulate a charging pump feed to Poppet valves that control the hydraulic feed to the cylinders. A hydraulic piston/cylinder drive is also provided for the shutdown rods which operate in either an all in or out of the core condition.

Assignee:

WESTINGHOUSE ELECTRIC COMPANY LLC - Cranberrry Township PA

International Classification:

G21C 7/14

US Classification:

376219

Abstract:

The present invention relates to a control rod drive mechanism assembly for a nuclear reactor having a nuclear reactor vessel, a nuclear reactor core, a reactor vessel head, a latch housing nozzle, a latch housing, a rod travel housing, a latch assembly, a drive rod assembly and a rod control cluster assembly. The latch housing is integrated with the latch housing nozzle, the rod travel housing is welded to the latch housing, and the latch assembly is connected to the rod travel housing. The latch assembly includes the drive rod assembly and the rod control cluster assembly which is attached to the drive rod assembly.

Appl. No.:

7/788706

Inventors:

Bruce F. Allen - Granby CT

Assignee:

Combustion Engineering, Inc. - Windsor CT

International Classification:

G21C 1900

US Classification:

376265

Abstract:

A vent tube (66) and housing nut (62) replace the original housing plug (52) on a pressurized water nuclear reactor. The vent tube engages the installed vent stem (38) cross-slot (48) with a cross-shaped projection (70). During operation, the vent tube (66) is pushed down to engage the vent stem (38) and rotated to allow vented air to travel through stem (38) and tube (66). After venting, the vent stem is rotated back and tightened. The invention provides visual indication of a leaking ball (32) since any leakage lifts vent tube (66). Time required for venting is reduced and no removal of installed ball seal (32,34), a proven primary seal, is required.

Assignee:

Combustion Engineering, Inc. - CT

International Classification:

G01M 328

US Classification:

73 495

Abstract:

An apparatus for hydrostatic pressure testing of tubular products that enables short segments of the tubular product to be individually tested under conditions simulating a capped tube hydrostatic test. The apparatus includes a first seal bladder and gripper member assembly connected to a second seal bladder and gripper member assembly by a connecting member that allows relative axial movement between the two assemblies. A fluid outlet port is provided in the connecting member to introduce pressurized fluid into the short segment of the tubular product between the seal bladders of the two assemblies. Since the first seal bladder and gripper member assembly is axially movable relative to the second seal bladder and gripper member assembly, an axial stress as well as a hoop stress will be induced in the tubular product during testing.

International Classification:

H01F 27/28
H01F 27/32
H01F 27/02

Abstract:

An improved electrical coil unit is described which includes generally a coil member encapsulated within an iron-containing metal housing wherein the housing has an increased surface area to better transfer heat and provide air flow during operation. Each coil unit includes a coil member comprising a bobbin made of a non-conducting fiberglass impregnated resin and an insulated copper wire coiled around the outer surface of the bobbin member in multiple layers. Each coil unit is housed in an iron containing metal housing. The exterior surface of the housing preferably includes a plurality of fins extending longitudinally around the housing. A coating material is provided to encapsulate the coil member within the housing to form an integrated coil unit. The integrated coil units may be stacked to form a coil stack assembly.
