Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
185 words
A DEVICE FOR DETECTING LEAKS IN THE JACKETS OF JACKETED BODIES OF FISSIONABLE MATERIAL DISPOSED INTO A HETEROGENEOUS NEUTRONIC REACTOR, COOLED BY A SERIES OF FLUID STREAMS CIRCULATING THROUGH SAID REACTOR IN HEAT-EXCHANGE RELATIONSHIP WITH SAID JACKETED BODIES, COMPRISING AT LEAST ONE DETECTOR FOR DETERMINING THE ACTIVITY OF THE IONIZING RADIATIONS, MEANS FOR BRINGING REPRESENTATIVE SAMPLES OF SAID FLUID STREAMS IN FRONT OF SAID AT LEAST ONE DETECTOR IN ORDER TO PERMIT THE DETERMINATION OF THE IONIZING ACTIVITY THEREOF, MEANS FOR STORING THE SUCCESSIVE INDICATIONS OF SAID AT LEAST ONE DETECTOR FOR SAID FLUID STREAM AT A REFERENCE MOMENT FOR A REFERENCE POWER OF SAID REACTOR, MEANS FOR DETERMINING THE POWER OF SAID REACTOR, MEANS FOR CORRECTING THE STORED INDICATIONS SO AS TO OBTAIN CORRECTED STORED ACTIVITIES REFERRED TO THE ACTUAL POWER OF SAID REACTOR, MEANS FOR COMPARING, FOR EACH FLUID STREAM, THE ACTUAL VALUE OF THE IONIZING ACTIVITY OF SAID STREAM, AS DETERMINED BY SAID AT LEAST ONE DETECTOR, TO SAID CORRECTED STORED ACTIVITY THEREOF, AND MEANS FOR VISUALIZING THE DIFFERENCE BETWEEN SAID ACTUAL VALUE AND SAID CORRECTED STORED ACTIVITY, FOR SAID FLUID STREAMS.
