  • Patent number: 10571880
    Abstract: An industrial controller that controls operation of an industrial system. The industrial controller comprises a processor and a memory storing instruction, wherein the instructions cause the processor to perform certain functions. In particular, the instructions cause the processor to communicate high speed data in a first industrial protocol between the industrial controller and a high speed device during a first frame section but not during a second frame section of a controller frame of the industrial controller and communicate linking device data in a second industrial protocol between the industrial controller and a linking device during the second frame section but not during the first frame section or during the third frame section of the controller frame.

  • Publication number: 20130010912
    Abstract: A neutron monitoring system uses a gamma thermometer to calibrate a nuclear instrument to ensure more accurate neutron flux measurements in a nuclear reactor core. The nuclear instrument generates a first signal proportional to a measured local neutron flux. The gamma thermometer generates a second signal proportional to a measured local gamma flux. A processor is used to compensate the second signal by filtering groups of delayed gamma sources to a reduced number of specific groups of delayed gamma sources. A third signal is calculated based upon yield fractions and time constants that are determined for the specific groups of delayed gamma sources. A gain of the nuclear instrument is calibrated based on a compensated second signal that is determined by subtracting the third signal from the second signal.

  • Patent number: 8238509
    Abstract: A method of calibrating a nuclear instrument using a gamma thermometer may include: measuring, in the instrument, local neutron flux; generating, from the instrument, a first signal proportional to the neutron flux; measuring, in the gamma thermometer, local gamma flux; generating, from the gamma thermometer, a second signal proportional to the gamma flux; compensating the second signal; and calibrating a gain of the instrument based on the compensated second signal. Compensating the second signal may include: calculating selected yield fractions for specific groups of delayed gamma sources; calculating time constants for the specific groups; calculating a third signal that corresponds to delayed local gamma flux based on the selected yield fractions and time constants; and calculating the compensated second signal by subtracting the third signal from the second signal. The specific groups may have decay time constants greater than 5×10?1 seconds and less than 5×105 seconds.
