Method Of Uprating An Existing Nuclear Power Plant

View page
US Patent:
6909765, Jun 21, 2005
Filed:
Feb 3, 2003
Appl. No.:
10/356950
Inventors:
Edward J. Lahoda - Pittsburgh PA, US
Assignee:
Westinghouse Electric Company LLC - Pittsburgh PA
International Classification:
G21C001/01
US Classification:
376260, 376210, 376211, 376212, 376261, 376241, 376267, 376402
Abstract:
An improved method of increasing the power output of an existing nuclear power plant includes increasing the thermal power output of the plant's nuclear island and constructing of an auxiliary BOP to handle the increased thermal power. The thermal power of the nuclear island can be increased such as by increasing the thermal power of the plant's reactor, by replacing the plant's steam generator with one that is more efficient, and by increasing the flow rate and/or change in temperature of a coolant in a secondary cooling loop of the plant. The thermal power of the reactor can be increased such as by replacing existing cylindrical fuel rods with fuel rods having a relatively greater surface area to volume ratio and/or by increasing the flow rate and/or the change in temperature of a coolant of a primary cooling loop. The auxiliary BOP can be constructed while the plant is in operation, and can then be connected with the nuclear island during a maintenance operation on the reactor.

Westinghouse Electric Co LLC - Cranberry Township PA
International Classification:
A61M 36/14
G21C 3/06
US Classification:
427 5, 427 6, 376261, 376419
Abstract:
A method for applying a burnable poison onto the cladding of a nuclear fuel rod () which comprises, providing a nuclear fuel rod () and at least one application device (), rotating the nuclear fuel rod, optionally removing one or more oxides and/or surface deposits on the outer surface of the nuclear fuel rod () by spraying an abrasive material onto the nuclear fuel rod via the application device () while adjusting the position of the application device in relation to the nuclear fuel rod (), and applying burnable poison particles () onto the outer surface () of the nuclear fuel rod () by spraying the burnable poison onto the nuclear fuel rod via the application device while adjusting the position of the application device () in relation to the nuclear fuel rod, where the burnable poison particles are applied at a velocity sufficient to cause adhesion to the outer surface () of the cladding.

Two Step Dry Uoproduction Process Utilizing A Positive Sealing Valve Means Between Steps

View page
US Patent:
7824640, Nov 2, 2010
Filed:
Jul 20, 2009
Appl. No.:
12/465729
Inventors:
Edward J. Lahoda - Pittsburgh PA, US
Assignee:
Westinghouse Electric Co. LLC - Cranberry Township PA
International Classification:
C01G 43/00
US Classification:
423261, 423253, 423258, 423483, 423 19
Abstract:
The present invention provides a two-step process for producing nuclear grade, active uranium dioxide (UO) powder in which the first step comprises reacting uranium hexafluoride (UF) with steam in a flame reactor to yield uranyl fluoride (UOF); and the second step comprises removing fluoride and reducing UOFto uranium dioxide (UO) in a kiln under a steam/hydrogen atmosphere. The two-step process, each step separated by a positive sealed valve means to prevent gas, particularly Hflow back, tightly controls the exothermicity of the reaction, which allows for a very tight temperature control which controls the growth of the particles and results in UOpowder that is active and of consistent morphology.

Gas Phase Electrolyzer Process For Producing Hydrogen

View page
US Patent:
7261874, Aug 28, 2007
Filed:
Jun 3, 2005
Appl. No.:
11/145320
Inventors:
Edward J. Lahoda - Pittsburgh PA, US
Keith D. Task - Pittsburgh PA, US
Assignee:
Westinghouse Electric Co. LLC - Pittsburgh PA
International Classification:
C01B 3/04
US Classification:
4236481, 204174, 204520, 423542, 423539
Abstract:
The invention provides a method for a sulfur based hydrogen production cycle wherein the sulfur products are maintained in a gaseous state throughout the cycle. The cycle includes a decomposition of a gaseous phase sulfur trioxide to sulfur dioxide and water in a decomposition reactor and an oxidation of gaseous sulfur trioxide with HO in an electrolyzer to form sulfur trioxide and hydrogen. Costs are reduced by elimination of energy costs previous necessary to convert the sulfuric products from liquid to gas and back again and by extending the lifespan of decomposition catalysts through the elimination of water in an SO/SOstream.
