What is ISO 15366-2-Nuclear fuel technology about?
ISO 15366 is an international standard on nuclear fuel technology. The main objective of ISO 15366 is Chemical separation and purification of uranium and plutonium in nitric acid solutions for isotopic and isotopic dilution analysis by solvent extraction chromatography.
ISO 15366-2 is the second part of a series of documents that 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 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. Annex A describes the preparation of the columns and the column support materials.
Who is ISO 15366-2-Nuclear fuel technology for?
ISO 15366-2 on nuclear fuel technology is useful for:
- Nuclear power stations
- Atomic energy agencies
- Atomic research organizations
- Nuclear power plants electrical systems and equipment manufacturers
- Operators of NPP, systems evaluators and licensors
- Nuclear safety authorities
- Regulatory authorities
Why should you use ISO 15366-2-Nuclear fuel technology?
The chemical separation of small plutonium and uranium amounts (>500 pg) is also based on column extraction chromatography using tri-n-octylphosphine-oxide (TOPO) as extractant.
ISO 15366-2 provides you with 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.
Adhere to standardized best-industry practiced process for chemically purifying uranium and plutonium in dissolved solutions of irradiated light water reactor fuels in samples of high active liquid waste of spent fuel reprocessing plants in accordance with ISO 15366-2.
