Nuclear safeguards is based on international agreements and within the EU has the rank of European law (Euratom treaty, Chapter VII, Euratom regulation 302/2005 ) ensuring that fissile material is used for peaceful purposes only.
One aspect of safeguards inspections is physical verification measurements at nuclear facilities. The IRMM-1027 series of LSD spikes are reference materials applied for the measurement of the uranium and plutonium content in spent fuel solutions by isotope dilution mass spectrometry (IDMS) at EURATOM safeguards laboratories as well as nuclear facilities. The spikes are prepared in large batches under rigorous conditions. They are dispensed into vials by means of an automated robot system.
IRMM-1027o is the first of the series of LSD spikes where the dried uranyl and plutonium nitrates are embedded in a cellulose substance with optimized characteristics. This provides a stable layer at the bottom of the vial and preserves the integrity of the spike during storage and transport. The IRMM-1027o certificate is valid for three years from the date of signature. The preparation and certification of IRMM-1027o is described in detail in the certification report, available together with the certificate in our online catalogue.
