Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
166 words
A CONTROL SYSTEM FOR A SINGLE CYCLE POWER SYSTEM INCLUDING A STEAM GENERATING NUCLEAR REACTOR, CONTROL RODS IN SAID REACTOR FOR GOVERNING THE POWER LEVEL OF SAID REACTOR, A TURBINE, AND VALVE MEANS FOR CONTROLLING THE RATE OF FLOW OF STEAM FROM THE REACTOR TO THE TURBINE, SAID CONTROL SYSTEM COMPRISING FIRST MEANS RESPONSIVE TO THE SPEED AT SAID TURBINE, SECOND MEANS RESPONSIVE TO THE PRESSURE IN SAID REACTOR, MEANS OPERATIVELY CONNECTING SAID FIRST MEANS TO SAID REACTOR TO SET THE CONTROL ROD POSITIONING SO AS TO VARY THE POWER LEVEL IN SAID REACTOR IN ACCORDANCE WITH SAID SPEED, MEANS OPERATIVELY CONNECTING SAID FIRST MEANS TO SAID SECOND MEANS TO SET A BASE PRESSURE FOR SAID REACTOR IN ACCORDANCE WITH SAID SPEED, AND MEANS OPERATIVELY CONNECTING SAID SECOND MEANS TO SAID VALVE MEANS TO VARY THE FLOW OF STEAM FROM SAID REACTOR TO SAID TURBINE IN ACCORDANCE WITH PRESSURE CHANGES IN SAID REACTOR AS SENSED BY SAID SECOND MEANS TO MAINTAIN SAID PRESSURE IN SAID REACTOR.
