Claim 1
Independent Claim
158 words
AN APPARATUS FOR INDENTIFYING A FUEL CHANNEL CONTAINING A LEAKING FUEL ELEMENT IN A NUCLEAR REACTOR CORE WHICH CONTAINS A PLURALITY OF SUCH FUEL CHANNELS THROUGH WHICH A FLUID IS PASSED AND WHICH IS CONTAINED IN A REACTOR VESSEL, WHICH APPARATUS COMPRISES A VAPOR-LIQUID SEPARATOR MEANS DISPOSED WITHIN SAID VESSEL IN FLUID-RECEIVING RELATION TO AND ADJACENT THE OUTLET OF SAID FUEL CHANNELS, AN EQUAL PLURALITY OF INDIVIDUAL SOLID ADSORBENT BODIES DISPOSED WITHIN SAID VESSEL APART FROM SAID FUEL CHANNELS, MEANS FOR PASSING A VAPOR SAMPLE FROM EACH OF SAID SEPARATOR MEANS THROUGH CONTACT WITH ONE OF SAID ADSORBENT BODIES TO ADSORB THEREON RADIOACTIVE DAUGHTER PRODUCTS OF NOBLE GAS FISSION PRODUCTS LEAKING INTO SAID FLUID, MEANS FOR REMOVING THE UNADSORBED FRACTIONS OF SAID VAPOR SAMPLES FROM SAID ADSORBENT BODIES AND FROM SAID VESSEL, AND MEANS FOR MEASURING THE REDIOACTIVITY OF EACH ADSORBENT BODY TO DETECT THE DEFECTIVE FUEL CHANNEL BY AN ANOMALOUSLY HIGH RADIOACTIVITY OF THE CORRESPONDING ADSORBENT BODY.
