Claim 1
Independent Claim
123 words
THE METHOD OF SAFELY OPERATING A NEUTRONIC REACTOR HAVING A STEAM FORMING COOLANT IN THE REACTOR CORE, WHICH COMPRISES PROVIDING A REACTOR HAVING A NEGATIVE REACTIVITY TO CORE VOID COEFFICIENT BETWEEN 0 AND 0.5% K PER PERCENT VOID AT THE REACTOR TEMPERATURE AT WHICH THE COOLANT COMMENCES BOILING, INITIATING A NEUTRONIC CHAIN REACTION WITHIN THE REACTOR BY INJECTING INTO THE REACTOR BETWEEN 0 AND 10% REACTIVITY GREATER THAN THE REACTIVITY REQUIRED TO PROVIDE A NEUTRON REPRODUCTION RATIO OF UNITY AT A TEMPERATURE JUST BELOW THE BOILING TEMPERATURE OF THE COOLANT, WHEREBY STEAM IS GENERATED IN THE CORE AND THE REACTIVITY INCREMENT IS NULLIFIED BY STEAM FORMATION IN THE CORE, AND INTRODUCING LIQUID COOLANT INTO THE CORE TO COMPENSATE FOR THE STEAM SO GENERATED.
