Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
106 words
IN THE METHOD OF CONTROLLING THE REACTIVITY OF THE CORE OF A BOILING-WATER NUCLEAR REACTOR OVER THE LOAD RANGE OF THE REACTOR, IN WHICH THE NUCLEAR REACTOR IS OF THE TYPE INCLUDING A REACTOR CORE, A WATER MODERATOR FOR THE CORE AND A STEAM SPACE FOR RECEIVING STEAM EVOLVED FROM THE WATER MODERATOR BOILED BY THE CORE, THE STEPS COMPRISING WITH DRAWING STEAM FROM THE STEAM SPACE OF THE REACTOR AND PASSING THE WITHDRAWN STEAM THROUGH THE REACTOR CORE, AND VARYING THE RATE AT WHICH STEAM IS PASSED THROUGH THE REACTOR CORE TO CONTROL THE REACTIVITY OF THE CORE OVER THE LOAD RANGE OF THE REACTOR.
Claim 2
Dependent Claim
106 words

Claim 3
Dependent Claim
110 words
IN A BOILING WATER NUCLEAR REACTOR OF THE TYPE INCLUDING A REACTOR CORE, A WATER MODERATOR FOR SAID CORE, AND MEANS DEFINING A STEAM SPACE FOR RECEIVING STEAM EVOLVED FROM THE WATER MODERATOR BOILED BY SAID CORE, THE IMPROVEMENT COMPRISING A STEAM LINE LEADING FROM SAID SPACE TO THE REACTOR CORE FOR CIRCULATING STEAM FROM SAID SPACE THROUGH THE REACTOR CORE FOR CONTROLLING THE REACTIVITY OF THE CORE OVER THE LOAD RANGE OF THE REACTOR, MEANS IN SAID LINE FOR EFFECTING THE CIRCULATION OF THE STEAM, A FURTHER STEAM LINE FOR CONNECTION TO A LOAD, AND VALVE MEANS FOR APPORTIONING BETWEEN SAID LINES THE STEAM EVOLVED FROM THE BOILING MODERATOR.
Claim 4
