Application of Ex-Vessel Neutron Dosimetry for Determination of Vessel Fluence
註釋Routine reactor cavity dosimetry measurements in four plants have been completed. Each of these measurements has included several multiple reaction sets that contain radiometric monitors and solid-state track recorders (SSTRs). The SSTRs are used to accurately determine fission rates using only extremely small amounts of very high purity fissionable material. The multiple reaction dosimetry sets were contained in holders suspended by wires extending from the top to the bottom of the cavity. These stainless steel wires were also analyzed to provide both fast and thermal neutron axial gradient data.
