Tehnologija nuklearnog goriva - Priprema šiljaka za masenu spektrometriju sa izotopskim razblaživanjem (IDMS) (ISO 6863:2024)

Nuclear fuel technology - Preparation of spikes for isotope dilution mass spectrometry (IDMS) (ISO 6863:2024)

Apstrakt

This document specifies a method which applies to the preparation and validation of the standard materials generally called “large size spikes” with an uncertainty suitable for international nuclear safeguards used for measuring the content of plutonium and/or uranium by isotope dilution mass spectrometry.
This measurement methodology can be applied to input solutions of irradiated Magnox and light water reactor fuels (boiling water reactor or pressurized water reactor); in final products at spent-fuel reprocessing plants; in feed and products of mixed oxide of plutonium and uranium (MOX); and in uranium fuel fabrication
