Control for a boiling type reactor supplying a steam turbine

Claim 1

IN A POWER PLANT INCLUDING A STEAM TURBINE SUPPLYING POWER TO A VARIABLE LOAD AT A SUBSTANTIALLY CONSTANT PREDETERMINED SPEED, A BOILING TYPE REACTOR FOR GENERATING STEAM TO OPERATE SAID TURBINE AND MEANS FOR CONDUCTING STEAM FROM SAID REACTOR TO SAID TURBINE, A CONTROL SYSTEM COMPRISING: A FIRST VALVE ASSEMBLY FOR CONTROLLING ADMISSION OF STEAM TO SAID TURBINE, A SECOND VALVE ASSEMBLY FOR CONTROLLING PRESSURE WITHIN SAID REACTOR, AND A GOVERNOR RESPONSIVE TO THE SPEED OF SAID TURBINE, SAID GOVERNOR BEING CONNECTED TO SAID FIRST AND SECOND VALVE ASSEMBLIES, SAID GOVERNOR BEING OPERATIVE IN RESPONSE TO TURBINE SPEED GREATER THAN SAID PREDETERMINED SPEED TO ADJUST SAID FIRST VALVE ASSEMBLY TO REDUCE THE FLOW OF STEAM TO SAID TURBINE AND TO ADJUST SAID SECOND VALVE ASSEMBLY TO DECREASE PRESSURE WITHIN SAID REACTOR TO REDUCE HEAT OUTPUT OF SAID REACTOR, AND SAID GOVERNOR BEING VICE VERSA OPERATIVE IN RESPONSE TO TURBINE SPEED LESS THAN SAID PREDETERMINED SPEED TO ADJUST SAID FIRST VALVE ASSEMBLY TO INCREASE THE STEAM FLOW TO SAID TURBINE AND TO ADJUST SAID SECOND VALVE ASSEMBLY TO INCREASE PRESSURE WITHIN SAID REACTOR TO INCREASE HEAT OUTPUT OF SAID REACTOR TO THEREBY OPERATE SAID TURBINE AT SAID PREDETERMINED SPEED AND MATCH THE HEAT OUTPUT OF SAID REACTOR TO THE VARIABLE HEAT INPUT REQUIREMENTS OF SAID TURBINE FOR VARIABLE LOADS.
