ABSTRACT:
An electronic system for operating a nuclear steam turbine power plant including a cycle steam reheater controller to control the heat transfer operation in a cycle steam reheater according to the steam and metal temperatures measured in one or more low pressure turbine sections, is disclosed. The steam and metal temperatures are closed-loop controlled as a function of the low pressure turbine design operational limitations. The reheater controller controls dual reheaters, each employing one or more heating sections which reheat cycle steam flowing therethrough to one or more low pressure turbine sections with split side entry steam inlet ports.
