Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A METHOD FOR PREPARING ACTINIDE OXIDE FUEL PARTICLES HAVING MULTIPLE CARBON COATINGS COMPRISING THE STEPS OF DEPOSITING A FIRST LOW DENSITY, HIGHLY POROUS CARBON COATING ONTO THE OXIDE FUEL CORES, DEPOSITING AS THIN HIGH DENSITY IMPERMEABLE LAYER OF MATERIAL ONTO SAID POROUS COATING, DEPOSITING A SECOND LOW DENSITY, HIGHLY POROUS CARBON COATING ONTO THIN HIGH DENSITY LAYER AND THEREAFTER DEPOSITING A HIGH DENSITY OUTER COATING A PYROLYTIC CARBON ONTO SAID POROUS COATING AT TEMPERATURE OF ABOVE 2000*C.
Claim 2
Independent Claim
77 words

Claim 3
Dependent Claim
58 words
AN ACTINIDE OXIDE FUEL PARTICLE COMPRISING A FUEL CORE; A FIRST LOW DENSITY, HIGHLY POROUS CARBON COATING SURROUNDING THE FUEL CORE; A THIN HIGH DENSITY PYROLYTIC CARBON COATING DISPOSED ABOUT SAID FIRST LOW DENSITY CARBON COATING, A SECOND LOW DENSITY, HIGHLY POROUS CARBON COATING SURROUNDING SAID THIN PYROLYTIC CARBON COATING; AND AN OUTER HIGH DENSITY PYROLYTIC CARBON COATING.
Claim 4
Dependent Claim
58 words
AN ACTINIDE OXIDE FUEL PARTICLE COMPRISING A FUEL CORE; A FIRST LOW DENSITY, HIGHLY POROUS CARBON COATING SURROUNDING THE FUEL CORE; A THIN HIGH DENSITY PYROLYTIC CARBON COATING DISPOSED ABOUT SAID FIRST LOW DENSITY CARBON COATING, A SECOND LOW DENSITY, HIGHLY POROUS CARBON COATING SURROUNDING SAID THIN PYROLYTIC CARBON COATING; AND AN OUTER HIGH DENSITY PYROLYTIC CARBON COATING.
