Download or read book Fused Salt Processing of Impure Plutonium Dioxide to High-purity Plutonium Metal written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A process for converting impure plutonium dioxide (approx. 96% pure) to high-purity plutonium metal (>99.9%) was developed. The process consists of reducing the oxide to an impure plutonium metal intermediate with calcium metal in molten calcium chloride. The impure intermediate metal is cast into an anode and electrorefined to produce high-purity plutonium metal. The oxide reduction step is being done now on a 0.6-kg scale with the resulting yield being>99.5%. The electrorefining is being done on a 4.0-kg scale with the resulting yield being 80 to 85%. The purity of the product, which averages 99.98%, is essentially insensitive to the purity of the feed metal. The yield, however, is directly dependent on the chemical composition of the feed. To date, approximately 250 kg of impure oxide has been converted to pure metal by this processing sequence. The availability of impure plutonium dioxide, together with the need for pure plutonium metal, makes this sequence a valuable plutonium processing tool.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the lack of suitable high level National Institute of Standards and Technology (NIST) traceable plutonium solution standards from the NIST or commercial vendors, the CST-8 Radiochemistry team at Los Alamos National Laboratory (LANL) has prepared instrument calibration standards and working standards from a well-characterized plutonium oxide. All the aliquoting steps were performed gravimetrically. When a [sup 241]Am standardized solution obtained from a commercial vendor was compared to these calibration solutions, the results agreed to within 0.04% for the total alpha activity. The aliquots of the plutonium standard solutions and dilutions were sealed in glass ampules for long term storage.

Book excerpt: Batches of plutonium dioxide were chlorinated by reaction with phosgene or carbon tetrachloride. Plutonium trichloride prepared by either method can be reduced to the metal in an hermetically sealed bomb by reaction with calcium. It has been demonstrated that a method for the reduction of plutonium trichloride to the metal without the use of a booster can be developed. Soluble plutonium in slag and crucible waste can be precipitated as the hydroxide and washed essentially free of chloride contamination. The concentrated nitric acid solution from dissolution of plutonium hydroxide and other solids contains less than 75 ppm chloride. Of the materials tested the Hastelloy alloys A, B, and C were found to be the most resistant to phosgene corrosion. The corrosion of these alloys was found to lie between 1 x 10−4 and 2 x 10−4 in. per month at 300 deg C and between 1 x 10−3 in. per month at 450 deg C. The logarithm of the corrosion rate plotted as a function of the temperature appears to be linear over the temperature range of 300 to 550 deg C. Above 550 deg C the corrosion rate of all materials tested is excessive. (auth).

Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
