Abstract
Disclosed is a control system and process for operating same for nuclear reactors, particularly gas cooled nuclear reactors, comprising in the control system a means for measuring the output produced in the reactor core and the output removed by a primary circuit or a secondary circuit, a means for integrating the integral of the core produced output over the output level, during the same time, of the primary or secondary circuit of the reactor and a means for forming a control signal from the value of the integral.
Claims13
An open-loop control process for operating nuclear reactors having a reactor core and a circuit for carrying out a work cycle, comprising:
- continuously generating over a discrete time interval the integral of the output produced by said reactor core minus the output removed in the same discrete time interval in said circuit of said reactor,
- continuously integrating said integral over said discrete time inteval, and
- utilizing predetermined threshold values of the integral and the determined integral values as parameters for shutdown of said reactor.
An open-loop shutdown system for nuclear reactors having a reactor core and a circuit for carrying out a work cycle comprising:
- means for measuring the output produced in said core and
- means for measuring the output removed by said circuit,
- means for generating the integral over a discrete time interval of said core-produced output less said output removed, from said circuit of said reactor and means for continuously integrating said integral over a discrete time interval and means for forming a shutdown signal where the value of said integrated integral exceeds a predetermined value.
