Model:

VERSA

Year:

US Patent:

7634043, Dec 15, 2009

Filed:

Dec 21, 2006

Appl. No.:

11/642920

Inventors:

Randall Howard Jacobs - Wilmington NC, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

G21C 17/00

US Classification:

376245, 376247, 376215

Abstract:

A protection system for a BWR may include a power-dependent high reactor pressure setpoint. The high reactor pressure setpoint that corresponds to at least one value of percent power in an operating domain of the reactor may be less than the high reactor pressure setpoint that corresponds to 100% power. A method of operating the BWR may include implementing the power-dependent high reactor pressure setpoint. The protection system may include a first high reactor pressure setpoint that corresponds to 100% power and at least one second high reactor pressure setpoint that corresponds to one or more values of percent power in the operating domain. The at least one second high reactor pressure setpoint may be less than the first high reactor pressure setpoint. The method of operating may include implementing the first high reactor pressure setpoint and the at least one second high reactor pressure setpoint.

Appl. No.:

12/637357

Inventors:

Randall Howard Jacobs - Wilmington NC, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

G21C 17/00

US Classification:

376245, 376247, 376215

Abstract:

A protection system for a nuclear boiling water reactor may include a device configured to monitor reactor power; a device configured to monitor reactor pressure; a device configured to determine a power-dependent high reactor pressure setpoint, based on the monitored reactor power; and a device configured to initiate a protection system action when the monitored reactor pressure is greater than the power-dependent high reactor pressure setpoint. The power-dependent high reactor pressure setpoint that corresponds to at least one value of percent power in an operating domain of the reactor may be less than the power-dependent high reactor pressure setpoint that corresponds to 100% reactor power.

International Classification:

G21C 3/322

Abstract:

Nuclear fuel assembly support castings direct fluid flow through nuclear fuel assemblies with relatively lower decay ratios and thus improved flow stability. The castings include an internal flow passage that is elongated to increase fluid flow inertia. The passage may be in excess of 0.3 meters and up to several meters in a straight, vertical direction that does not disrupt inertial fluid flow. Castings may omit an entry orifice and replicate any orifice-driven pressure drop with a specifically-sized flow passage that causes a similar pressure drop, or castings may use a side or bottom entry orifice at an entrance to the passage. Castings accommodate any number of fuel assemblies and other core structures including control blades, instrumentation tubes, core plates, and other core structures, such as four fuel assemblies arranged in a grid on the casting with a cruciform control element extending through a center of the casting.
