Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
A COATED ARTICLE HAVING INCREASED STABILITY UNDER PROLONGED EXPOSURE TO HIGH TEMPERATURE AND NEUTRON IRRADIATION, WHICH ARTICLE COMPRISES A CENTRAL CORE SELECTED FROM THE GROUP CONSISTING OF NUCLEAR FUEL MATERIALS AND NEUTRON POISON MATERIALS, AND A PROTECTIVE COATING SURROUNDING SAID CORE, SAID COATING INCLUDING A DENSE CONTINUOUS JACKET OF ISOTROPIC CARBON WHICH ISOTOPIC CARBON HAS GOOD STRUCTURAL STRENGTH AND DIMENSIONAL STABILITY UNDER CONDITIONS OF HIGH TEMPERATURE AND HIGH NEUTRON IRRADIATION, SAID ISOTROPIC CARBON JACKET COMPLETELY SURROUNDING SAID CORE.
Claim 2
Dependent Claim
