Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
85 words
A METHOD OF MEASURING THE DISTRIBUTION OF FLUX IN THE CORE OF A NUCLEAR REACTOR COMPRISING THE SUCCESSIVE STEPS OF INTRODUCING A FILAMENT OF AN INERT GAS OF HIGH NEUTRON CAPTURE CROSS-SECTION INTO A SMALL BORE TUBE EXTENDING THROUGH THE REACTOR CORE, IRRADIATING THE FILAMENT OF THE INERT GAS IN THE CORE FOR A PERIOD, SUBJECTING THE FILAMENT TO A CHANGE IN VELOCITY, REMOVING THE FILAMENT FROM THE CORE, AND MEASURING THE DISTRIBUTION OF NEUTRON FLUX ALONG THE LENGTH OF THE WITHDRAWN FILAMENT OF GAS.
Claim 2
Independent Claim
85 words

Claim 3
Dependent Claim
87 words
APPARATUS FOR MEASURING THE DISTRIBUTION OF FLUX IN THE CORE OF A NUCLEAR REACTOR COMPRISING A SMALL-BORE TUBE EXTENDING THROUGH THE CORE, MEANS INCORPORATING A COMPOUND PISTON TO CAUSE A FILAMENT OF AN INERT GAS OF HIGH NEUTRON CAPTURE CROSS-SECTION TO FLOW THROUGH THE TUBE AT TWO DIFFERENT VELOCITIES, AN ACTIVITY RECORDER OUTSIDE THE CORE TO MEASURE THE DISTRIBUTION OF ACTIVITY IN THE INERT GAS ALONG THE FILAMENT, AND MEANS TO DIFFERENTIATE THE MEASURED DISTRIBUTION OF ACTIVITY TO OBTAIN THE DISTRIBUTION OF FLUX IN THE REACTOR CORE.
