Abstract: Fine and coarse resolvers are used to detect the length of cable withdrawn from a spool to provide an indication of the position of a neutron flux detector at the end of the cable. The position indicated by the resolvers when the neutron flux detector passes a withdrawn limit switch is stored in nonvolatile memory as an offset when the cable is first installed in a flux mapping system. Thereafter, the position indicated by the resolvers, each time the neutron flux detector passes the withdraw limit switch, is compared to the offset. If the difference between the two is significant, a warning is generated, but operation of the flux mapping system continues. During movement of the flux detector, the change in position between two readings of the resolvers is divided by an amount of time measured by a programmable interval timer to determine average speed. A warning is generated if the average speed is outside an expected range. The expected range may vary depending upon the position of the detector.

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.

Abstract: A detector path insertion verification system for use with flux mapping of a pressurized water nuclear reactor uses a transfer insertion switch at the input of each multiple-path selector to detect insertion of a detector into the multiple-path selector. No insertion switches are used at the output of the multiple-path selectors; instead software is used to verify the position of the multiple-path selectors. The sensed actual position of each multiple-path selector is monitored as the multiple-path selector is rotated to verify that the sensed actual position passes through the expected sequence of positions in an expected amount of time. The multiple-path selectors are rotated until a sensed actual position is equal to a desired position and rotation is stopped. After the passage of a short period of time, the actual and desired positions are again compared and if equal, insertion is begun.
