G06F 1900
US Classification:

702 38, 702 97, 324228, 324220, 324234, 324238
Abstract:

A method of synthesizing nondestructive examination data of a component including the steps of generating nondestructive examination data of the component in the field and separately generating nondestructive examination data of a specimen machined to simulate selected flaws in the component and combining portions of the specimen data with the field data in a combined data stream.

US Patent:

7647829, Jan 19, 2010
Filed:

Nov 22, 2006
Appl. No.:

11/562782
Inventors:

Warren R. Junker - Monroeville PA, US
John P. Lareau - Granby CT, US
Assignee:

Westinghouse Electric Co. LLC - Cranberry Township PA
International Classification:

G01H 3/00
G01N 29/34
US Classification:

73592, 73620, 73622, 73644
Abstract:

A method of examining a steam generator heat exchange tube from the outside surface employing ultrasonic nondestructive inspection techniques. An ultrasonic transducer contacts the outside surface of the tube and transmits a pseudo helical Lamb wave into the wall of the tube chosen to have a mode that does not significantly interact with water in the tube. The reflected waves are then analyzed for changes in modes to identify defects in the wall of the tube.

G06F 19/00
US Classification:

702 38, 324237, 324240, 702 75, 702 85
Abstract:

A method of synthesizing nondestructive examination data of a component that combines data sets acquired at least two different frequencies. At least one of the data sets is interpolated or extrapolated to the equivalent of data acquired at one of the other frequencies employing a third, reference set of eddy current inspection data that is acquired at each of the inspection frequencies being combined.

US Patent:

7815964, Oct 19, 2010
Filed:

Mar 29, 2007
Appl. No.:

11/692952
Inventors:

Edward J. Lahoda - Pittsburgh PA, US
Warren R. Junker - Monroeville PA, US

John P. Lareau - Granby CT, US
Assignee:

Westinghouse Electric Co LLC - Cranberry Township PA
International Classification:

A61M 36/14
G21C 3/06
US Classification:

427 5, 427 6, 376261, 376419
Abstract:

A method for applying a burnable poison onto the cladding of a nuclear fuel rod () which comprises, providing a nuclear fuel rod () and at least one application device (), rotating the nuclear fuel rod, optionally removing one or more oxides and/or surface deposits on the outer surface of the nuclear fuel rod () by spraying an abrasive material onto the nuclear fuel rod via the application device () while adjusting the position of the application device in relation to the nuclear fuel rod (), and applying burnable poison particles () onto the outer surface () of the nuclear fuel rod () by spraying the burnable poison onto the nuclear fuel rod via the application device while adjusting the position of the application device () in relation to the nuclear fuel rod, where the burnable poison particles are applied at a velocity sufficient to cause adhesion to the outer surface () of the cladding.

Filed:

Dec 21, 2009
Appl. No.:

12/642935
Inventors:

Thomas W. Nenno - Murrysville PA, US
Warren R. Junker - Monroeville PA, US
Richard M. Novotny - New Kensington PA, US
Conrad S. Wyffels - New Ulm MN, US
Assignee:

Westinghouse Electric Company LLC - Cranberry Township PA
International Classification:

G01N 27/82
US Classification:

324240, 324220, 324222, 324242, 324339, 32475501, 324239, 324241
Abstract:

An eddy current probe testing apparatus structured to operate concurrently in a driver pick-up mode and said impedance mode is provided. The eddy current probe has two coils. The eddy current probe testing apparatus also includes a signal producing device, an output device, and a switch assembly. The switch assembly is structured to switch how an input signal from the signal producing device is provided to the two coils.

Appl. No.:

11/198482
Inventors:

Warren Junker - Monroeville PA, US

International Classification:

B05D 3/00
B05D 7/00
B05D 1/12
US Classification:

427140000, 427421100, 427180000
Abstract:

The wetted surface of a pressure vessel, a structural internal or a weld is repaired by removing the contacting radioactive fluid, forming a powder mixture of metallic particles and ceramic particles and then spraying the powder mixture on the formerly wetted surface to form a protective cold sprayed coating thereon. As-deposited coatings having a surface smoothness of 125 RMS or better may be nondestructively examined by ultrasonic, eddy current or dye penetrant tests without a preliminary grinding step.

US Patent:

20100040186, Feb 18, 2010
Filed:

May 21, 2008
Appl. No.:

12/124398
Inventors:

Warren R. Junker - Monroeville PA, US
International Classification:

G21C 17/07
US Classification:

376251
Abstract:

A method for determining a leaking nuclear fuel rod that remotely measures the internal pressure in the plenum region of the fuel rod by remotely measuring the thermal response of the rod when a localized heating is imposed on the outside of the rod in the plenum region. The temperature of the cladding at two symmetrically spaced points on either side of the location where the heating is imposed is remotely monitored as a function of time and compared to a standard to determine the internal pressure of the plenum.
