Ion Beam Assisted Deposition Of Thermal Barrier Coatings

View page
US Patent:
7838083, Nov 23, 2010
Filed:
Jan 28, 2006
Appl. No.:
11/343127
Inventors:
Dennis L. Youchison - Albuquerque NM, US
Jimmie M. McDonald - Albuquerque NM, US
Thomas J. Lutz - Albuquerque NM, US
Michail A. Gallis - Albuquerque NM, US
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
C23C 14/08
C23C 14/30
C23C 14/48
C23C 14/54
B05D 3/06
US Classification:
427529, 427528, 427567, 427595, 427597, 427533
Abstract:

Porous Nuclear Fuel Element For High-Temperature Gas-Cooled Nuclear Reactors

View page
US Patent:
7899146, Mar 1, 2011
Filed:
Jun 29, 2004
Appl. No.:
10/881873
Inventors:
Dennis L. Youchison - Albuquerque NM, US
Brian E. Williams - Pacoima CA, US
Robert E. Benander - Pacoima CA, US
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
G21C 3/62
A61M 36/14
US Classification:
376222, 376221, 376414
Abstract:
Porous nuclear fuel elements for use in advanced high temperature gas-cooled nuclear reactors (HTGR's), and to processes for fabricating them. Advanced uranium bi-carbide, uranium tri-carbide and uranium carbonitride nuclear fuels can be used. These fuels have high melting temperatures, high thermal conductivity, and high resistance to erosion by hot hydrogen gas. Tri-carbide fuels, such as (U,Zr,Nb)C, can be fabricated using chemical vapor infiltration (CVI) to simultaneously deposit each of the three separate carbides, e. g. , UC, ZrC, and NbC in a single CVI step. By using CVI, the nuclear fuel may be deposited inside of a highly porous skeletal structure made of, for example, reticulated vitreous carbon foam.
