Available in PDF, EPUB and Kindle. Book excerpt: Extensive pilot plant studies of the mercury-catalyzed nitric acid dissolution of unirradiated 7.5% uranium--92.5% aluminum alloy slugs were carried out in tall-pipe, flooded, continuous dissolvers, In producing an acidic product containing 1.2M aluminum nitrate, dissolution rates as high as 15 kg of aluminum per day per square inch of cross section were achieved. Countercurrent flow of metal and acid has some advantages over concurrent flow, The large heat of reaction produced great volumes of steam in the dissolvers; the operational problems due to the resulting foam were best solved by the use of an over head reflux condenser to condense, partially or totally, the steam in the off-gas. Only minor quantities of solids were found in acidic product solutions. Extruded alloy dissolved abcut twice as fast as cast alloy, The metal dissolving rate was directly proportional to the 0.8 power of the nitric acid feed rate and tc the cube root of the mercuric ion (catalyst) concentration. The maximim dissolving rates occurred at feed acid concentrations of abcut 3M for cast slugs and 5M for extruded alloy, The system studied is inherently self-regulating in that a uniform product composition will normally be produced by feeding slugs, nitric acid, and catalyst at constant rates. The occasional minor rate adjustments are best accomplished by varying the catalyst concentration. Data and correlations developed are given. (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.

Book excerpt: Several processing options for dissolving plutonium oxide (PuO[sub 2]) from high-fired materials have been studied. The scoping studies performed on these options were focused on PuO[sub 2] typically generated by burning plutonium metal and PuO[sub 2] produced during incineration of alpha contaminated waste. At least two processing options remain applicable for dissolving high-fired PuO[sub 2] in canyon dissolvers. The options involve solid solution formation of PuO[sub 2] With uranium oxide (UO[sub 2]) and alloying incinerator ash with aluminum. An oxidative dissolution process involving nitric acid solutions containing a strong oxidizing agent, such as cerium (IV), was neither proven nor rejected. This uncertainty was due to difficulty in regenerating cerium (IV) ions during dissolution. However, recent work on silver-catalyzed dissolution of PuO[sub 2] with persulfate has demonstrated that persulfate ions regenerate silver (II). Use of persulfate to regenerate cerium (IV) or bismuth (V) ions during dissolution of PuO[sub 2] materials may warrant further study.

This book was released on 1990 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Savannah River Plant (SRP), operated by E.I. du Pont de Nemours Co. for the United States Department of Energy, has successfully recovered plutonium from plutonium-aluminum alloy processed through the F-Canyon Separations facility. The alloy, produced at the Rocky Flats Plant, results from recovery of plutonium residues from spent chloride salts from pyrochemical processing. The alloy, termed scrub alloy'' or Rocky Flats scrub alloy'' (RFSA), contains up to 15 weight percent chloride impurity prior to mercuric ion catalyzed dissolution with fluoride-containing nitric acid. Solutions containing 850 to 3000 [mu]g/mL (parts per million) of chloride result. During subsequent Purex solvent extraction of this solution with 30% tri-n-butyl phosphate in normal paraffin diluent, chloride is rejected to the aqueous waste stream. This stream is eventually evaporated for waste treatment and acid recovery. Chloride concentrations in the product streams, subject to further processing, must be less than 100 [mu]g/mL to prevent excessive corrosion of equipment. This paper describes scrub alloy production at RFP, its dissolution and head end treatment to remove chloride, chloride values in subsequent processing streams including environmental discharges, and the turbidimetric analysis technique. 2 tabs.
