The JRC-IRMM-1027 series of LSD spikes are reference materials applied to measure the uranium and plutonium content of spent fuel solutions by isotope dilution mass spectrometry (IDMS) at EURATOM safeguards laboratories and nuclear facilities.
They are widely used as a fundamental part of the fissile material control of irradiated nuclear fuel. The spikes are prepared in large batches under rigorous conditions and dispensed in vials by means of an automated robot system.
As part of the successful series of large-sized dried (LSD) spikes for uranium and plutonium produced at the JRC-IRMM, a new batch, labelled IRMM-1027p has been produced following ISO Guide 34:2009.
The IRMM-1027p certificate is valid for three years from the date of signature. The preparation and certification of IRMM-1027p is described in detail in the certification report, available together with the certificate in our online catalogue.
Nuclear safeguards is based on international agreements and in the EU has the rank of European law (Euratom treaty, Chapter VII, Euratom regulation 302/2005 ). Nuclear safeguards are established as a guarantee that nuclear materials for peaceful use are not diverted to purposes other than those for which they were originally declared. Parts of safeguards inspections are physical verification measurements at nuclear facilities.
