Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
98 words
THE METHOD OF REGULATING A NUCLEAR REACTOR HAVING A CORE WITH FUEL CHANNELS AND MOVABLE NEUTRON-ABSORPTIVE FLOATABLE CONTROL MEANS, WHICH COMPRISES CAUSING COOLANT LIQUID TO BOIL TO STEAM IN A SELECTED FUEL CHANNEL AT A GIVEN OPERATING CONDITION BELOW FULL POWER RATING OF THE REACTOR, SAID CHANNELS BEING SEPARATELY COOLED FROM THE REMAINDER OF THE CORE, CONDENSING THE STEAM TO COOLANT LIQUID IN A CHAMBER SEPARATE FROM SAID FUEL CHANNEL, AND VARIABLY DISPLACING THE CONTROL MEANS INTO VARIOUS DEGREES OF IMMERSED CONDITION WITHIN SAID CHAMBER RELATIVE TO THE CORE IN DEPENDENCE UPON OCCURENCE OF BOILING IN SAID CHANNEL.
Claim 2
