Eddy Current For The Characterization Of Broached Tube Support Plate Blockage
US Patent:
8527216, Sep 3, 2013
Filed:
Feb 8, 2010
Appl. No.:
12/702142
Inventors:
John C. Griffith - Lynchburg VA, US
Joseph R. Wyatt - Lynchburg VA, US
Mihai G. M. Pop - Lynchburg VA, US
Jeffrey M. Fleck - Forest VA, US
Joseph R. Wyatt - Lynchburg VA, US

Assignee:
Areva NP Inc - Lynchburg VA
International Classification:
G01B 7/34
G01B 5/28
G01B 5/28
US Classification:
702 38, 324222
Abstract:
A method for determining tube support plate blockage of a steam generator includes the following steps: measuring at least five different eddy current values per tube support intersection; calculating a nominal clean fit radius of flow hole; determining a center signal response; converting the center signal response to a deposit thickness; determine an edge reduction; converting the edge reduction to an edge thickness; calculating the resulting flow hole radius; verifying the reasonableness of the resulting flow hole radius; and determining a virtual calibration range.
Steam Generator Mapping System
US Patent:
2008000, Jan 10, 2008
Filed:
Jul 10, 2006
Appl. No.:
11/484227
Inventors:
Joseph R. Wyatt - Lynchburg VA, US
John Griffith - Lynchburg VA, US
Victor Newman - Forest VA, US

International Classification:
G01B 7/06
US Classification:
324229
Abstract:
A method to determine deposits in a steam generator having the steps of creating a calibration standard having at least two rings of deposit material, subjecting the calibration standard to an eddy current signal, wherein an amplitude of the signal reflected from the calibration standard is used to obtain a polynomial equation fit of the reflected eddy current signals to actual thickness of the rings, obtaining a steam generator with tubes, initiating an eddy current signal into the tubes of the steam generator, detecting and recording reflections of the eddy current signal initiated into the tubes of the steam generator, and determining a thickness of the deposits in the steam generator from the recorded reflections of the eddy current signal and the polynomial equation.

Viscous Damping Stabilizer
US Patent:
2014005, Feb 27, 2014
Filed:
Aug 16, 2013
Appl. No.:
13/968524
Inventors:
Jeffrey C. Brown - Forest VA, US
Jeffrey M. Fleck - Forest VA, US
Jeffrey M. Fleck - Forest VA, US
Assignee:
AREVA NP Inc. - Lynchburg VA
International Classification:
F22B 37/20
F16F 7/00
F16F 7/01
F16F 7/00
F16F 7/01
US Classification:
165 69, 188266, 188268
Abstract:
The inventive viscous damping tube stabilizer includes modules or capsules containing a viscous material. Adjacent capsules are linked end to end by a flexible cable, allowing the device o pass through curves such as the U-bend regions of steam generator tubes. The weight of the entire assembly will keep it essentially connected to the tube inner diameter such that any tube vibration is transmitted to the stabilizer. The viscous material may only partially fill the capsules such that even under small motion the material can slip and slide past each other, and/or bump into walls, each microscopically absorbing some of the tube energy. By creating multiple cells inside the capsule, the capsule then have good operating characteristics no matter to what angle the individual capsule is oriented as it rests on the full U-bend. The viscous material may completely fill the capsules, which also have a perforated member positioned therein. Relative movement of the capsule and disc causes the viscous material to pass through the perforations, providing damping resistance to the movement.
