Appl. No.:

09/683335

Inventors:

Jose L. Casillas - Cupertino CA
Eugene C. Eckert - Los Gatos CA
Phuong T. Tran - Pleasanton CA

Assignee:

General Electric Company - Schenectady NY

International Classification:

G21C 1700

US Classification:

376245, 376207, 376210, 376219, 376246, 376247

Abstract:

A computerized method for expanding the operating domain of a boiling water nuclear reactor that permits safe operation of the reactor at core flows lower than normal operating parameters is provided. The operating domain is characterized by a map of the reactor thermal power and core flow. The computerized method includes determining by computer simulation a load line characteristic that is elevated over normal operating parameters and that increases reactor performance over normal operating parameters, performing safety evaluations by computer simulation at the elevated load line to determine compliance with safety design parameters, and performing operational evaluations by computer simulation at the elevated load line.

International Classification:

G21C 17/00

US Classification:

376245, 216259

Abstract:

A method for expanding the operating domain of a boiling water nuclear reactor that permits safe operation of the reactor at low core flows is described. The operating domain is characterized by a map of the reactor thermal power and core flow. In an exemplary embodiment, the method for expanding the operating domain of a boiling water nuclear reactor permits operation of the reactor between about 120 percent of rated thermal power and about 85 percent of rated core flow to about 100 percent of rated thermal power and about 55 percent of rated core flow. The method includes determining an elevated load line characteristic that improves reactor performance, performing safety evaluations at the elevated load line to determine compliance with safety design parameters, and performing operational evaluations at the elevated load line. The method also includes defining a set of operating conditions for the reactor in an upper operating domain characterized by the elevated load line. Additionally, the method includes performing a detailed analysis of the performance of the core recirculation system and the system control components.

International Classification:

G06F 17/30

US Classification:

707723

Abstract:

A graphical display of objects by a computer system comprises receiving a plurality of objects for display to a user; presenting for display on a display screen of an electronic device a plurality of sets of frames in increasingly smaller radial patterns, wherein after a first set of frames, each successive set of frames is nested within an immediately preceding set of frames; and presenting for display in the sets of frames at least a portion of the objects to form nested radial arrays of objects.
