SYSTEM FOR VISUALLY VERIFYING TRANSITORY ABNORMALITIES IN THE OPERATION OF A NUCLEAR REACTOR.

摘要

A system for monitoring a limited number of operating conditions in a nuclear reactor and for graphically displaying same on a display device is disclosed. The system parameters selected are those which typically change as a result of a reactor trip. As long as these system parameters remain within a "post-trip window" on the graphic display, the power plant is operating normally. If, however, any of the foregoing system parameters falls outside this "window", this is an immediate indication to the power plant operator to institute the necessary procedures to remedy same. A sequential controller (26) is provided to continuously sequentially sample the foregoing operating parameters and to transmit data regarding same to the display device.
