Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
A NUCLEAR-FUEL ELEMENT COMPRISING A LONG MASS OF CERAMIC FUEL CONTAINING A RELATIVELY LOW AMOUNG OF A MATERIAL FISSIONABLE BY NEUTRONS OF THERMAL ENERGY AND A VARYING HELICAL WIRE OF A METALLIC FUEL CONTAINING A RELATIVELY HIGH AMOUNT OF A MATERIAL FISSIONABLE BY NEUTRONS OF THERMAL ENERGY EXTENDING AXIALLY OF THE MASS, WHEREIN THE VARYING HELICAL WIRE IS A HELICAL WIRE OF PITCH VARYING FROM A MAXIMUM AT A MID REGION TO A MINIMUM AT THE ENDS OF THE WIRE.
Claim 2
Dependent Claim
80 words

Claim 3
Dependent Claim
88 words
A NUCLEAR-FUEL ELEMENT COMPRISING A LONG MASS OF CERAMIC FUEL CONTAINING A RELATIVELY LOW AMOUNT OF A MATERIAL FISSIONABLE BY NEUTRONS OF THERMAL ENERGY AND A VARYING HELICAL WIRE OF METALLIC FUEL CONTAINING A RELATIVELY HIGH AMOUNT OF A MATERIAL FISSIONABLE BY NEUTRONS OF THERMAL ENERGY EXTENDING AXIALLY OF THE MASS, WHEREIN THE VARYING HELICAL WIRE IS A HELICAL WIRE OF A DIAMETER OF HELIX VARYING FROM A MINIMUM AT A MID REGION IN THE LENGTH OF THE WIRE TO A MAXIMUM AT THE ENDS OF THE WIRE.
