چکیده
The present paper describes the individual analytical methodologies (Thermal Ionization Mass Spectrometry, Inductively Coupled Plasma Mass Spectrometry and Alpha Spectrometry) that were developed for uranium age determination and discusses their advantages and drawbacks. With respect to a potential application of the methods (e.g. Fissile Material Cut-off Treaty), the discussion focuses on highly enriched uranium, as this appears to be of highest strategic relevance. The different analytical methodologies were tested using uranium reference materials of different U enrichments and of known ages.

Age determination of highly enriched uranium: separation and analysis of 231Pa.
An analytical procedure has been developed for the age determination of highly enriched uranium samples exploiting the mother/daughter pair 235U/231Pa. Protactinium is separated from bulk uranium through highly selective sorption to silica gel and is subsequently quantified using alpha-spectrometry. The method has been validated using uranium standard reference materials of known ages. It affor...

COLUMN PRECONCENTRATION OF URANIUM BY 1 -(2-PY RIDYLAZ0)-2-NAPHTHOL SUPPORTED ON NAPHTHALENE USING DIF'FERENTLAL PULSE POLAROGRAPHY
A solid chelating material, 1-(2-pyridy1azo)-2-naphthol (PAN) supported on naphthalene provides a rapid and highly selective means of preconcentration of uranium from aqueous solution. Uranium is quantitatively retained on this adsorbent in the pH range 9.8-10.7 with a flow rate of 1 ml min . The metal complex was desorbed with 10 ml of 2 M hydrochloric acid and uranium is determined by d...
متن کاملPlutonium age dating (production date measurement) by inductively coupled plasma mass spectrometry.
This paper describes rapid methods for the determination of the production date (age dating) of plutonium (Pu) materials by inductively coupled plasma mass spectrometry (ICP-MS) for nuclear forensic and safeguards purposes. One of the presented methods is a rapid, direct measurement without chemical separation using 235U/239Pu and 236U/240Pu chronometers. The other method comprises a straightfo...
متن کاملBasic characterization of highly enriched uranium by gamma spectrometry
Gamma-spectrometric methods suitable for the characterization of highly enriched uranium samples encountered in illicit trafficking of nuclear materials are presented. In particular, procedures for determining the U, U, U, U and U contents and the age of highly enriched uranium are described. Consequently, the total uranium content and isotopic composition can be calculated. For determining the...
