Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
A METHOD FOR MONITORING THE POWER DISTRIBUTION THROUGHOUT A NUCLEAR CHAN REACTING ASSEMBLY DISPOSED IN A REACTOR VESSEL AND HAVING A PLURALITY OF NUCLEAR FUEL-CONTAINING COOLANT FLOW CHANNELS THROUGH WHICH A LIQUID COLLANT IS PASSED, WHICH METHOD COMPRISES THE STEPS OF COLLIMATING PENETRATING RADIATION EMITTED AXIALLY FROM A RELATIVELY SMALL LOCAL REGION OF SAID ASSEMBLY INCLUDING AT LEAST ONE OF SAID FLOW CHANNELS, MEASURING THE INTENSITY OF THE COLLIMATED RADIATION AT A POINT REMOTE FROM SAID ASSEMBLY AND OUTSIDE OF SAID VESSEL, THE ATTENUATION OF SAID RADIATION VARYING WITH CHANGES IN THE DENSITY AND THE TEMPERATURE OF SAID COOLANT THROUGH WHICH IT PASSES AND THE POWER LEVEL IN SAID CHANNEL FROM WHICH IT ISSUES WHEREBY THE COLIMATED RADIATION HAS AN INTENSITY WHICH IS A DIRECT FUNCTION OF SAID POWER LEVEL, AND REPEATING THE RADIATION COLLIMATION AND COLLIMATED RADIATION INTENSITY MEASUREMENT STEPS FOR A PLURALITY OF SAID RELATIVELY SMALL LOCAL REGIONS TO DETERMINE SAID POWER DISTRIBUTION.

Claim 3
Independent Claim
99 words
AN APPARATUS FOR MONITORING THE POWER LEVEL IN EACH OF A PLURALITY OF RELATIVELY SMALLL LOCAL REGIONS OF A NUCLEAR CHAIN REACTING ASSEMBLY INCLOSED WITHIN A VESSEL WHICH COMPRISES A PLURALITY OF PENETRATING RADIATION DETECTING MEANS DISPOSED AT POINTS REMOTE FROM SAID ASSEMBLY AND OUTSIDE SAID VESSEL, A PLURALITY OF RADIATION COLLIMATING MEANS DISPOSED BETWEEN SAID DETECTING MEANS AND SAID ASSEMBLY, EACH OF SAID COLLIMATING MEANS BEING ALIGNED WITH A CORRESPONDING ONE OF SAID PLURALITY OF RELATIVELY SMALL LOCAL REGIONS OF SAID ASSEMBLY, EACH OF SAID COLLIMATING MEANS BEING DISPOSED IMMEDIATELY ADJACENT A CORRESPONDING ONE OF SAID DETECTING MEANS.
Claim 4
