Abstract

PURPOSE: To permit operation by automatically carrying out an operation mode where the main steam pressure or inner pressure within a steam generator is made constant over the entire range of the rate of flow of the steam generator.
CONSTITUTION: When the output of a linear function unit 29 is selected for connection to a switch 31, a signal proportional to the output of main steam flow rate detector 26 is supplied from the linear function generator 29 to a change factor limiter 32. With this signal the limiter 32 automatically changes its output signal according to the main steam flow rate while limiting the change factor. Thus, the set potential d of the change factor limiter 32 is changed in proportion to the main steam flow rate to make the actual main steam pressure constant over the entire flow region. When the output of a non-linear function unit 30 is selected for connection to the switch 31, the function is set such that it is the sum of the main steam resistance represented as a power of the main steam flow rate and pressure increase proportional to the main steam flow rate, so that the actual inner pressure within the steam generator 1 is made constant over the entire flow rate region.
