Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
92 words
A METHOD OIF CONTROLLING THE STARTUP TRANSIENT IN AN OVERMODERATED, WATER-COOLED NUCLEAR REACTOR CONTAINING COLUMNS OF FUEL ELEMENTS ALIGNED IN A PLURALITY OF COOLANT TUBES WHEREIN WATER PASSES THROUGH THE COOLANT TUBES COMPRISING MOVING THE FRONT HALF OF THE COLUMN OF FUEL ELEMENTS UPSTREAM AND MOVING THE REAR HALF OF THE COLUMN OF FUEL ELEMENTS DOWNSTEARM TO SEPARATE THE HALVES OF THE FUEL ELEMENT COLUMN DURING THE TRANSIENT INCREASE IN REACTIVITY CAUSED BY ZENON BURNOUT AND MOVING THE HALVES OF THE FUEL ELEMENT COLUMN TOGETHER AS REACTIVITY DECREASES BECAUSE OF XENON BUILDUP.

Claim 3
Dependent Claim
104 words
APARATUS FOR CONTROLLING AN OVERMODERATED NUCLEAR REACTOR WHICH CONTAINS ROWS OF TUBULAR FUEL ELEMENTS SLIDABLY DISPOSED IN PARALLEL, HORIZONTAL TUBES AND WHEREIN WATER IS FLOWED THROUGH THE TUBES PAST THE FUEL ELEMENTS COMPRISING A SPROCKET IN THE UPSTREAM END OF AT LEAST ONE TUBE, A SPROCKET CHAIN ENGAGING SAID SPROCKET, A FIRST CABLE PASSING THROUGH THE FUEL ELEMENTS AND ATTACHED TO THE FARTHEST DOWNSTREAM FUEL ELEMENT, A SECOND CABLE PASSING THROUGH THE FUEL ELEMENT AND ATTACHED TO A FUEL ELEMENT NEAR THE MIDDLE OF THE REACTOR, AND MEANS FOR ROTATING THE SPROCKET TO SEPARATE OR BRING TOGETHER HALVES OF THE COLUMN OF FUEL ELEMENTS.
