Title: Digital computer operation of a nuclear reactor

Abstract

A method is described for the safe operation of a complex system such as a nuclear reactor using a digital computer. The computer is supplied with a data base containing a list of the safe state of the reactor and a list of operating instructions for achieving a safe state when the actual state of the reactor does not correspond to a listed safe state, the computer selects operating instructions to return the reactor to a safe state.

  • A hybrid digital computer gas turbine power plant control system which may operate in a multiple control loop arrangement is provided with selected process variable monitoring and control and turbine system failure detection means. More specifically, open, shorted, grounded and reversed thermocouples are detected and alarmed. Problems of any one combustor in a multiple combustor arrangement are similarly detected and alarmed. Additionally, automatic correction of previously computed temperature related control inputs is provided in response to detected variations from a predetermined temperature reasonability criterion. Novel placement and orientation of system thermocouples facilitates achieving improved monitoring, detection and control.
  • This patent describes a control system for a nuclear reactor in which the power level is altered by adjustments in reactor reactivity. It comprises means for determining the reactivity of the nuclear reactor, the determining means having a cycle time which is less than the delayed neutron lifetimes in the nuclear reactor; and stepping drive means for adjusting the reactivity by incrementally changing a parameter by a fixed amount of either plus or minus one unit.
