G.E.-Hitachi Nuclear Energy Americas Assigned Patent for Very Simplified Boiling Water Reactors

Targeted News Service (Patent Abstracts)

ALEXANDRIA, Va., July 9 -- G.E.-Hitachi Nuclear Energy Americas, Wilmington, North Carolina, has been assigned a patent (No. 10,706,973, initially filed May 2, 2017) developed by three co-inventors for "very simplified boiling water reactors for commercial electricity generation." The co-inventors are Brian S. Hunt, Wilmington, North Carolina, Christer N. Dahlgren, Wilmington, North Carolina, and Wayne Marquino, Wilmington, North Carolina.

The abstract states: "Nuclear reactors have very few systems for significantly reduced failure possibilities. Nuclear reactors may be boiling water reactors with natural circulation-enabling heights and smaller, flexible energy outputs in the 0-350 megawatt-electric range. Reactors are fully surrounded by an impermeable, high-pressure containment. No coolant pools, heat sinks, active pumps, or other emergency fluid sources may be present inside containment, emergency cooling, like isolation condenser systems, are outside containment. Isolation valves integral with the reactor pressure vessel provide working and emergency fluid through containment to the reactor. Isolation valves are one-piece, welded, or otherwise integral with reactors and fluid conduits having ASME-compliance to eliminate risk of shear failure. Containment may be completely underground and seismically insulated to minimize footprint and above-ground target area."
