Claim 1
Independent Claim

A METHOD OF CONTROLLING THE TEMPERATURE WITHIN A NUCLEAR REACTOR IN WHICH COOLANT TRAVERSES THE REACTOR CORE IN A PLURALITY OF PASSES, COMPRISING MONITORING THE OUTLET TEMPERATURE OF THE COOLANT FROM EACH PASS, BYPASSING A PORTION OF THE COOLANT FLOW FROM THE REACTOR INLET LINE TO THE INLET OF EACH COOLANT PASS, AND ADJUSTING THE FLOW THROUGH THE BYPASS LINES INVERSELY WITH RESPECT TO VARIATIONS IN THE OUTLET TEMPERATURE OF THE LAST PASS BYPASSED WHILE MAINTAINING TOTAL COOLANT THROUGH THE REACTOR CONSTANT.
