- Summary
- A novel technique has been developed at Argonne National Laboratory to determine the ²³⁹Pu content in EBR-II blanket elements using resonance transmission analysis (RTA) with a filtered reactor beam. The technique uses cadmium and gadolinium filters along with a ²³⁹Pu fission chamber to isolate the 0.3 eV resonance in ²³⁹Pu. In the energy range from 0.1 to 0.5 eV, the total microscopic cross-section of ²³⁹Pu is significantly larger than the cross-sections of ²³⁸U and ²³⁵U. This large difference in cross-section allows small amounts of ²³⁹Pu to be detected in uranium samples. Tests using a direct beam from a 250 kW TRIGA reactor have been performed with stacks of depleted uranium and ²³⁹Pu foils. Preliminary measurement results are in good agreement with the predicted results up to about two weight percent of ²³⁹Pu in the sample. In addition, measured ²³⁹Pu masses were in agreement with actual sample masses with uncertainties less than 3.8 percent.
