Filed:

Jun 5, 2001

Appl. No.:

09/875449

Inventors:

Deborah Pence - Corvallis OR, US
Jose Reyes - Corvallis OR, US
Nathan Phillips - Brighton MA, US
Qiao Wu - Portland OR, US
John Groome - Corvallis OR, US

International Classification:

H02B001/00
H02B001/56
H05K007/20

US Classification:

361/676000, 361/677000

Abstract:

Thermal management devices and methods include branching networks comprising flow channels of varying cross-sectional area. The branching networks can be fractal-like in nature with an increase in the total flow area following a flow channel bifurcation. In representative embodiments, the branching networks are defined in a channel pattern that is laminated between cover plates to form a thermal management device. The channel pattern includes bridging portions so that the branching network is defined with a single pattern piece. The branching networks can exhibit radial symmetry or be aligned with respect to one or more axes. Heat exchangers and diffusive mixers that include such networks are also provided.

International Classification:

G21C 1/32

US Classification:

376405

Abstract:

A nuclear reactor module includes a reactor vessel containing coolant, a reactor core submerged in the coolant, and a heat exchanger configured to remove heat from the coolant. The nuclear reactor module further includes one or more heaters configured to add heat to the coolant during a startup operation and prior to the reactor core going critical.

International Classification:

G21C 7/00

US Classification:

376214

Abstract:

A stable startup system includes a reactor vessel containing coolant, a reactor core submerged in the coolant, and a heat exchanger configured to remove heat from the coolant. The stable startup system further includes one or more heaters configured to add heat to the coolant during a startup operation and prior to the reactor core going critical.
