Claim 1
Independent Claim
135 words
A METHOD FOR THE DETERMINATION OF WHETHER THE SPECIFIC NEUTRONIC REACTIVITY OF A SPECIMEN OBJECT IS VARIANT FROM THAT OF A STANDARD OBJECT WHICH COMPRISES THE NONSIMULTANEOUS INTRODUCTION OF A STANDARD OBJECT OF KNOWN SPECIFIC NEUTRONIC REACTIVITY AND A SPECIMEN OBJECT OF A SIZE, SHAPE AND COMPOSITION SIMILAR TO SAID STANDARD OBJECT INTO A POSITION IN A NECLEAR REACTIVE ASSEMBLY OF THERMAL NEUTRON FISSIONABLE MATERIAL AND MODERATOR HAVING A NEUTRON SOURCE, SAID ASSEMBLY HAVING AN EFFECTIVE THERMAL NEUTRON MULTIPLICATION CONSTANT WITH ONE OF SAID OBJECTS IN SAID ASSEMBLY OF BETWEEN ABOUT 0.95 AND 0.995, EXPOSING A NEUTRON FLUX DETECTOR AT A SECOND POSITION IN SAID ASSEMBLY TO THE EQUILIBRIUM NEUTRON FLUX LEVELS RESULTANT FROM THE INTRODUCTION OF SAID OBJECTS INTO THE ASSEMBLY, AND ACTIVATING AN INDICATING ELECTROMETER MEANS OPERABLY RESPONSIVE TO SAID NEUTRON FLUX DETECTOR.
