Book PREPARATION OF URANIUM IV  NITRATE SOLUTIONS

Download or read book PREPARATION OF URANIUM IV NITRATE SOLUTIONS written by and published by . This book was released on 1961 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A procedure was developed for the preparation of uranium(IV) nitrate solutions in dilute nitric acid. Zinc metal was used as a reducing agent for uranium(VI) in dilute sulfuric acid. The uranium(IV) was precipitated as the hydrated oxide and dissolved in nitric acid. Uranium(IV) nitrate solutions were prepared at a maximum concentration of 100 g/l. The uranium(VI) content was less than 2% of the uranium(IV). (auth).

Available in PDF, EPUB and Kindle. Book excerpt: The Directorate G "Nuclear Safety and Security", Unit G.2 "Standards for Nuclear Safety, Security and Safeguards" (SN3S) at the European Commission's Joint Research Centre, Geel in Belgium (formerly known as the "Institute for Reference Materials and Measurements" (IRMM)), provides a wide range of nuclear Certified Reference Materials (CRMs) to the safeguards authorities and the nuclear industry. This is an obligation under the Euratom treaty, where the need for isotope standards is explicitly mentioned, acknowledging their importance for the measurements of nuclear materials. For accurate mass spectrometric measurements in nuclear material accountancy and nuclear safeguards, suitable CRMs are needed to validate measurement procedures and to calibrate instruments. In particular, for mass spectrometry, CRMs are needed which have been prepared and characterized using procedures which are independent on mass spectrometric techniques as much as possible. One possible way to achieve this, is to use highly isotopically enriched starting materials and mix them under gravimetrical control in the correct proportions to achieve given targets for the isotope ratios. This procedure has been applied for the preparation of uranium and plutonium isotope CRMs for many years by several institutions, like NIST, NBL and IRMM/JRC-Geel. In the 1980s, the IRMM-072 series [7] of isotope mixtures containing 233U, 235U and 238U in various proportions was prepared based on this approach/method. About 20 years later, the isotope mixing program was restarted, and several further isotope CRMs were prepared and certified: the IRMM-074 [4] and IRMM-075 series [5], and the IRMM-3636a double spike [6]. In 2009, the IRMM-3000 series was prepared. It consists of a set of five highly enriched uranium nitrate solution reference materials named IRMM-3020, IRMM-3035, IRMM-3050, IRMM-3075 and IRMM-3090 with 235U enrichments varying from 20 % to 90 %. The solutions were prepared by dissolving uranium oxide (U3O8) materials, which were prepared by gravimetrically mixing oxides that are highly enriched in 235U and 238U. However, the verification measurements by TIMS showed some significant differences from the calculations based on the gravimetrical preparation. It was suspected that incomplete impurity analyses of the 238U starting material could be the cause for most of the differences, but this could not be confirmed at that time. Recently, the certification project for the IRMM-3000 series was restarted, including new mass spectrometric analyses of the isotope ratios performed at several laboratories and new impurity analysis for the 238U starting material.
