Nuclear fuel technology - Controlled-potential coulometric measurement of plutonium (ISO/DIS 12183:2023)

ISO 12183:2016 describes an analytical method for the electrochemical assay of pure plutonium nitrate solutions of nuclear grade, with a total uncertainty not exceeding ±0,2 % at the confidence level of 0,95 for a single determination (coverage factor, K = 2). The method is suitable for aqueous solutions containing more than 0,5 g/L plutonium and test samples containing between 4 mg and 15 mg of plutonium. Application of this technique to solutions containing less than 0,5 g/L and test samples containing less than 4 mg of plutonium requires experimental demonstration by the user that applicable data quality objectives will be met.
For some applications, purification of test samples by anion exchange is required before measurement to remove interfering substances when present in significant amounts.

Technologie du combustible nucléaire - Dosage du plutonium par coulométrie à potentiel imposé (ISO/DIS 12183:2023)

L'ISO 12183:2016 décrit une méthode analytique pour le dosage électrochimique de plutonium pur dans des solutions nitriques de qualité nucléaire, avec une incertitude ne dépassant pas ± 0,2 % dans un intervalle de confiance de 0,95 pour une simple détermination (facteur d'élargissement, K = 2). La méthode est adaptée aux solutions aqueuses contenant plus de 0,5 g/L de plutonium et à des échantillons d'essai contenant entre 4 mg et 15 mg de plutonium. L'application de cette technique aux solutions contenant moins de 0,5 g/L et d'échantillons d'essai contenant moins de 4 mg de plutonium exige que l'utilisateur démontre expérimentalement que les objectifs relatifs à la qualité des données applicables soient atteints.
Pour certaines applications, une purification des échantillons d'essai par échange anionique est nécessaire avant la mesure pour éliminer les substances interférentes présentes en quantités significatives. Se reporter à l'Article 10 qui traite des interférences et des actions correctives. La purification est aussi nécessaire dans les situations où la pureté de l'échantillon d'essai n'est pas connue ou quand elle peut fluctuer de façon imprévisible dans le procédé de fabrication.
L'Article 11 traite des changements dans l'application de la méthode et de la méthodologie qui peuvent être appliquées et des considérations importantes pour sélectionner les paramètres de mesure, tout en restant à l'intérieur du domaine d'application du présent document.
