ABSTRACT:
A plurality of flux map sequences are stored in nonvolatile memory to control a flux mapping operation in a nuclear reactor. The flux map sequences are accessed by a host controller which receives instructions from either a local man machine interface or a remote man machine interface. A system control unit determines which of the man machine interfaces is active and also provides the ability to select manual control of detector drivers. A selected flux map sequence is displayed and can be modified and then restored or executed. The modifications to the flux map sequence may include deleting a detector driver from the flux mapping operation and then automatically redistributing the thimbles originally used by the deleted detector driver to be used by the remaining detector drivers. The man machine interfaces are preferably independent computer systems each connected to receive shared data transmitted from the host controller and capable of performing analysis on the flux map data including generating calibration data for a plant protection system. The flux mapping system also includes a diagnostic processor for monitoring the operation of the host controller and ensuring that the detector drivers receive instructions to return to a safe condition if there is a malfunction of the host controller.
