Measurements have been performed at the time-of-flight facility GELINA to determine the total cross section for neutron induced reactions in natCe. The measurements have been carried out at the 50 m transmission station at a moderated neutron beam using a Li-glass scintillator with the accelerat...
In February 2004 the new Triton Thermal Ionization Mass Spectrometer from Thermo Electron has been installed at IRMM. For uranium isotope ratio measurements on the Triton at IRMM two basic techniques have been introduced and validated, namely the MTE- (“Modified Total Evaporation”) and the HI- (...
The REIMEP 18 (Regular European Inter-laboratory Measurement Evaluation Programme) campaign was started in October 2005. For this campaign 4 samples of depleted to low-enriched uranium were chosen. Certification measurements were carried out using a Varian MAT511 UF6-gas source mass spectrometer...
This certification report describes the processing and characterisation of ERM®-FA415z, a batch of Charpy V-notch reference test pieces certified for the absorbed energy (KV) for tests at 20 °C. Sets of five of these test pieces are used for the verification of pendulum impact test machines acco...
This certification report describes the processing and characterisation of ERM®-FA015x and ERM®-FA015y, two batches of Charpy V-notch certified reference test pieces. Sets of five of these test pieces are used for the verification of pendulum impact test machines according to EN 10045-2 (Charpy ...
Four solutions with different isotopic composition were prepared as samples for the NUSIMEP-5 comparison exercise. Each contained uranium (5 ppb), two in addition Pu and two Cs in low amounts in a 1 % saline solution. The uranium isotopic abundances were certified at IRMM on 4 individual UF6 mat...
In this final report, a methodology, human and financial resources as well as realisation of the planned activities within the CARDS 2003 project "Albania metrology" are described. For the latter, measurable indicators are given. All the changes to the plan, as stated in the inception report, th...
The proficiency test here reported concerned the determination of the four marker polycyclic aromatic hydrocarbons (PAHs) in an olive oil test sample: benz[a]anthacene, benzo[a]pyrene, benzo[b]fluoranthene, and chrysene. Participants to these PT were National Reference Laboratories for PAHs (NRL...
This report describes the preparation and characterisation of a set of plasmid solutions, ERM-AD483a, ERM-AD483b and ERM-AD483c. The materials were produced in accordance with ISO Guide 34:2009. A DNA fragment specific for the identification of a porcine target was cloned into a pUC18 vector to ...
A new set of Large Size Dried (LSD) Spikes for the determination of uranium and plutonium by isotope dilution mass spectrometry in solutions of spent fuel from reprocessing plants has been prepared and certified for uranium and plutonium isotopic contents. The methodology followed was similar to...
