Available in PDF, EPUB and Kindle. Book excerpt: A nondestructive gamma-ray technique has been developed to determine plutonium isotopic ratios. The technique is based on the high-intensity, low-energy gamma rays at 43.48, 45.23, 51.63, 59.54, and 64.83 keV for 238Pu, 24°Pu, 239Pu, 241Am, and 241Pu, respectively. The results demonstrate that this technique can accurately measure plutonium samples in a timely manner and in a wide range of masses, isotopic contents, chemical forms, and ages from chemical processing.

Available in PDF, EPUB and Kindle. Book excerpt: A gamma-ray spectrometry system has been developed for the Savannah River Plant that when coupled with calorimetry will allow a complete nondestructive assay of various plutonium product and waste materials contained in sealed cans. The computer-based system employs two germanium detectors to obtain spectral information that is analyzed in a unique fashion to obtain plutonium isotopic ratios.

Available in PDF, EPUB and Kindle. Book excerpt: The Plutonium Inventory Verification Program at Mound Laboratory provides a nondestructive means of assaying bulk plutonium-bearing material. The assay is performed by combining the calorimetrically determined heat output of the sample and the relative abundances of the heat-producing isotopes. This report describes the method used for the nondestructive determination of plutonium-238, -240, -241 and americium-241 relative to plutonium-239 using gamma-ray spectroscopy for 93 percent plutonium-239 material. Comparison of chemical data on aliquots of samples to the nondestructive data shows accuracies of +-7 percent for 238Pu/239Pu, +-15 percent for 24°Pu/239Pu, +- 3 percent for 241Pu/239Pu, and +-7 percent for 241Am/239Pu.

Available in PDF, EPUB and Kindle. Book excerpt: We discuss the general approach, computerized data analysis methods, and results of measurements used to determine the isotopic composition of plutonium by gamma-ray spectroscopy. The simple techniques are designed to be applicable to samples of arbitrary size, geometry, age, chemical, and isotopic composition. The combination of the gamma spectroscopic measurement of isotopic composition coupled with calorimetric measurement of total sample power is shown to give a totally nondestructive determination of sample plutonium mass with a precision of 0.6% for 1000-g samples of PuO2 with 12% 24°Pu content. The precision of isotopic measurements depends upon many factors, including sample size, sample geometry, and isotopic content. Typical ranges are found to be 238Pu, 1 to 10%; 239Pu, 0.1 to 0.5%; 24°Pu, 2 to 5%; 241Pu, 0.3 to 0.7%; 242Pu (determined by isotopic correlation); and 241Am, 0.2 to 10%.

Available in PDF, EPUB and Kindle. Book excerpt: We have designed and built a gamma-ray spectrometer system that measures the relative plutonium isotopic abundances of plutonium oxide enriched in 238Pu. The first system installed at Westinghouse Savannah River Company was tested and evaluated on plutonium oxide in stainless steel EP60/61 containers. 238Pu enrichments ranged from 20% to 85%. Results show that 200 grams of plutonium oxide in an EP60.61 container can be measured with {plus minus}0.3% precision and better than {plus minus}1.0% accuracy in the specific power using a counting time of 50 minutes. 3 refs., 2 figs.
