Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
A METHOD FOR DETERMINING THE INTEGRITY OF A JACKET ENCLOSING A NEUTRON-FISSIONABLE FUEL ELEMENT, COMPRISING PLACING THE JACKETED FUEL ELEMENT IN A SEALED TANK WITHIN THE ACTIVE PORTION OF A NUCLEAR REACTOR, PARTIALLY FILLING SAID TANK WITH A LIQUID HAVING A LOW NUETRON ABSORPTION CROSS-SECTION SO AS TO IMMERSE THE FUEL ELEMENT, OPERATING THE REACTOR, SPARGING THE LIQUID WITHIN THE TANK WITH A NONRADIOACTIVE GAS HAVING A LOW NUETRON ABSORPTION CROSS-SECTION WHILE OPERATING THE REACTOR AND MONITORING THE EFFLUENT GAS FOR THE PRESENCE OF ENTRAINED RADIOACTIVE FISSION PRODUCT GAS.
