Claim 1
Independent Claim
82 words
THE METHOD OF MEASURING THE REACTIVITY OF A SELFSUSTAINING NUCLEAR REATION IN A REACTOR, COMPRISING THE STEPS OF; INDUCING A PREDETERMIND VARIATION IN THE MULTIPLICATION FACTOR OF THE SELF-SUSTAINING REACTION AT ONE POSITION IN SAID REACTOR, DETECTING A SUBSEQUENT VARIATION, AT AOTHER POSITION IN SAID REACTOR, IN THE REACTION RESULTING FROM SAID VARIATION IN THE MULTIPLICATION FACTOR, AND DETECTING THE TIME LAPSE BETWEEN SAID VARIATION IN THE REACTION AND THE CORRESPONDING VARIATION IN THE MULTIPLICATION FACTOR AS THE MEASURE OF SAID REACTIVITY.
