Method And Apparatus For Evaluating A Proposed Solution To A Constraint Problem For A Nuclear Reactor Involving Channel Deformation
US Patent:
8041548, Oct 18, 2011
Filed:
Dec 30, 2004
Appl. No.:
11/024433
Inventors:
David Joseph Kropaczek - Wilmington NC, US

Assignee:
Global Nuclear Fuels-Americas, LLC - Wilmington NC
International Classification:
G06G 7/48
G05B 13/02
G21C 7/00
G05B 13/02
G21C 7/00
US Classification:
703 6, 703 2, 700 28, 376327, 376332, 376333, 376334, 376335
Abstract:
A method of and a system for evaluating constraint functions for improving nuclear reactor performance involve generating an operational solution for a nuclear reactor using a constraint to account for a problem with the operation of the nuclear reactor. The problem is based at least in part on channel deformation criteria.

Global Nuclear Fuel - Americas LLC - Wilmington NC
International Classification:
G06F 3/048
G06F 3/00
G06F 3/00
US Classification:
715764, 715771, 715781, 715848, 715866, 376215, 376245, 703 6
Abstract:
An apparatus generating a graphical image of a core of a boiling water reactor (BWR) using at least one data set of channel deformation data including: a computer system including a display device for presenting the graphical image and a processor generating the graphical image using the at least one data set; the graphical image of the core includes symbolic representations of control blades arranged in the core, indicia identify each control blade, and indicia regarding deformation of channels adjacent each control blade, and a viewer software tool executed by the processor which accesses the at least one data set and determines a location in the core of the control blades and channels, and correlates the deformation data with the channels for display on the graphical image.
Systems And Methods Of Predicting A Critical Effective K For A Nuclear Reactor
US Patent:
2008012, May 29, 2008
Filed:
Nov 29, 2006
Appl. No.:
11/606320
Inventors:
Ugur Mertyurek - Wilmington NC, US
David Joseph Kropaczek - Wilmington NC, US
Atul A. Karve - Wilmington NC, US
Angelo P. Chopelas - Wilmington NC, US

International Classification:
G21C 7/36
US Classification:
376217
Abstract:
Systems and methods for a method for determining a critical effective k at an off-rated core state of a nuclear power plant includes determining, for the off-rated core state a control rod density, a percent core power, a gadolinium reactivity worth, a doppler reactivity worth, and a xenon reactivity worth responsive to a control rod pattern, a reactor power plan including the off-rated core state, and a reference effective k, calculating a change in an effective k from the reference effective k at the off-rated core state responsive to two or more parameters selected from the group consisting of the control rod density, the percent core power, the gadolinium reactivity worth, the doppler reactivity worth, and the xenon reactivity worth, and generating the critical effective k for the off-rated core state responsive to the change in the effective k from the reference effective k.
