Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
42 words
A FUEL MATERIAL FOR A NUCLEAR REACTOR COMPRISING A DISPERSION OF MIXED ZIRCONIUM AND PULTONIUM DIOXIDES IN A MATRIX FORMED OF A ZIRCONIUM-BASED ALLOY HAVING A LOW NEUTRON-CAPTURE CROSS SECTION RENDERING SAID ALLOY SUITABLE FOR USE AS A MATRIX FOR REACTOR FUEL.
Claim 2
Dependent Claim
42 words
A FUEL MATERIAL FOR A NUCLEAR REACTOR COMPRISING A DISPERSION OF MIXED ZIRCONIUM AND PULTONIUM DIOXIDES IN A MATRIX FORMED OF A ZIRCONIUM-BASED ALLOY HAVING A LOW NEUTRON-CAPTURE CROSS SECTION RENDERING SAID ALLOY SUITABLE FOR USE AS A MATRIX FOR REACTOR FUEL.
Claim 3
Dependent Claim
71 words
A FUEL ELEMENT FOR A NUCLEAR REACTOR COMPRISING A FUEL MATERIAL IN A CLADDING MATERIAL IN WHICH THE FUEL MATERIAL COMPRISES A DISPERSION OF MIXED ZIRCONIUM AND PULTONIUM DIOXIDES IN A MATRIX FORMED OF A PRESSURIZED WATER CORROSION RESISTANT ZIRCONIUM-BASED ALLOY HAVING A LOW NEUTRON-CAPTURE CROSS SECTION RENDERING SAID ALLOY SUITABLE FOR USE AS A MATRIX FOR REACTOR FUEL AND THE CLADDING MATERIAL IS THE SAME ZIRCONIUM-BASED ALLOY AS THE MATRIX.
Claim 4
Dependent Claim
71 words
A FUEL ELEMENT FOR A NUCLEAR REACTOR COMPRISING A FUEL MATERIAL IN A CLADDING MATERIAL IN WHICH THE FUEL MATERIAL COMPRISES A DISPERSION OF MIXED ZIRCONIUM AND PULTONIUM DIOXIDES IN A MATRIX FORMED OF A PRESSURIZED WATER CORROSION RESISTANT ZIRCONIUM-BASED ALLOY HAVING A LOW NEUTRON-CAPTURE CROSS SECTION RENDERING SAID ALLOY SUITABLE FOR USE AS A MATRIX FOR REACTOR FUEL AND THE CLADDING MATERIAL IS THE SAME ZIRCONIUM-BASED ALLOY AS THE MATRIX.
