ISO 15366-2:2014 describes procedures to chemically separate and purify uranium and plutonium in dissolved solutions of irradiated light water reactor fuels and in samples of high active liquid waste of spent fuel reprocessing plants, prior to their isotopic analysis by e.g. mass spectrometric method or alpha spectrometry. ISO 15366-2:2014 describes a slightly different separation technique from ISO 15366-1, based on the same chemistry, using smaller columns, different support material and special purification steps, applicable to samples containing plutonium and uranium amounts in the nanogram range and below. The detection limits were found to be 500 pg plutonium and 500 pg uranium.

Abstract

Overview - EN ISO 15366-2:2016 (ISO 15366-2:2014)

EN ISO 15366-2:2016 is a CEN-adopted international standard for nuclear fuel technology that specifies chemical separation and purification procedures for uranium and plutonium in nitric acid solutions prior to isotopic and isotope-dilution analysis by techniques such as mass spectrometry or alpha spectrometry. It targets very low-level samples - plutonium and uranium in the nanogram range and below - and documents a solvent-extraction chromatography method using mini-columns coated with tri-n‑octylphosphine‑oxide (TOPO). The method’s detection limits were determined as ≈500 pg for both plutonium and uranium.

Key topics and technical requirements

Scope and sample types: Dissolved solutions from irradiated light-water reactor fuel and high-activity liquid waste from spent fuel reprocessing plants.
Separation principle: Extraction chromatography on disposable mini-columns with TOPO-coated supports (polyethylene or silica) in 3 mol·L−1 HNO3; selective retention of Pu(IV) and U(VI).
Valency control: Use of iron(II) sulfate and sodium nitrite to adjust oxidation states prior to separation.
Elution and purification:
- Plutonium eluted after chemical reduction (e.g., ascorbic acid).
- Uranium eluted with ammonium carbamate and further purified by anion exchange resin or fuming with concentrated HNO3.
Column and support details: Mini-columns (disposable polypropylene) packed with polyethylene powder coated with TOPO; Annex A describes packing and conditioning.
Quality and operational controls: Run blanks and control samples in parallel; work in clean conditions (laminar-flow fume hood or shielded glovebox); gravity flow rates should not exceed 0.4 mL·min−1.
Reagents and apparatus: Suprapure-grade reagents (HNO3, HCl, TOPO in cyclohexane, ammonium carbamate, ascorbic acid, etc.), PTFE vials, shielded workspace and hotplates.

Practical applications and users

Nuclear fuel and reprocessing laboratories performing isotopic analysis, isotope-dilution mass spectrometry and alpha spectrometry on ultra‑low-level uranium and plutonium samples.
Radioanalytical and safeguards labs requiring validated separation methods for trace-level plutonium/uranium in spent fuel dissolution solutions and high-activity wastes.
Environmental and forensic labs analyzing minute nuclear materials where robust separation and low detection limits (≈500 pg) are critical.

ISO 8299 - Guidance related to mass spectrometric isotopic analysis.
ISO 11483 - Alpha spectrometry method references.

This standard is essential for practitioners implementing solvent extraction chromatography workflows for trace-level uranium and plutonium isotopic measurements, ensuring reproducible separation, low blank levels, and compatibility with downstream mass spectrometry or alpha spectrometry analysis.
