Title
(EN) SYSTEMS AND METHODS FOR SEPARATING ISOTOPES FROM A SAMPLE OF FISSION PRODUCTS
(FR) SYSTÈMES ET PROCÉDÉS POUR SÉPARER DES ISOTOPES D'UN ÉCHANTILLON DE PRODUITS DE FISSION
Abstract
(EN)
Systems and methods for efficient, effective, and safe separation and isolation of multiple isotopes (e.g., Mo, Zr, Ba, Sr, Te, and lanthanide isotopes) from fission products includes use of a plurality of chromatography columns, each containing a chromatographic resin formulated to target one or more particular isotopes. The system is operable in a "series" configuration to load the multiple columns by a single pass of the sample. Then, the system may be transitioned (e.g., using valves) to a "parallel" configuration in which multiple columns of the system may be operated simultaneously to elute targeted isotopes. Additional parallel operations of the columns, using different eluent compositions, may be used to elute different targeted isotopes. The system may be reconditioned in preparation for a subsequent sample.

L'invention concerne des systèmes et des procédés permettant de séparer et isoler de manière efficiente, efficace et sûre de multiples isotopes (par exemple, Mo, Zr, Ba, Sr, Te, et des isotopes des lanthanides) à partir de produits de fission. Les procédés consistent à utiliser une pluralité de colonnes chromatographiques contenant chacune une résine chromatographique formulée pour cibler un ou plusieurs isotopes particuliers. Le système peut être mis en oeuvre dans une configuration "série" pour charger les multiples colonnes en un seul passage de l'échantillon. Le système peut ensuite être amené (par exemple, à l'aide de soupapes) à une configuration "parallèle" dans laquelle de multiples colonnes du système peuvent être actionnées simultanément pour éluer des isotopes ciblés. Des opérations parallèles supplémentaires des colonnes peuvent être utilisées, à l'aide de différentes compositions d'éluant, pour éluer différents isotopes ciblés. Le système peut être reconditionné pour préparer un échantillon ultérieur.
