For years now, experts in the nuclear field have expressed and pointed out the widespread need for Nuclear Reference Materials (NRMs) in the whole of the nuclear fuel cycle. NRMs were defined as actinides with well characterized chemical, isotopic and/or physical properties for use as a common base for the calibration of instruments and checking of analytical methods. Since nuclear energy from fission reactors is an increasing contributor to the electricity generating capacity in the EC, there is an equivalent demand for accurate analytical measurements in the various stages of the fuel cycle and in associated fields such as: (i) commercial transactions (ii) production control (iii) nuclear material accounting (safeguards) (iv) waste disposal (v) environment and health physics (vi) research and development An essential element for improving analyses and measurements is the availability and use of the appropriate NRMs. The first extensive enquiry into the needs for NRMs in the EC was undertaken by JRC-Geel in 1977. The enquiry was conducted in close collaboration with national experts and resulted in a listing of needs and available resources in the EC. Table 1 lists the high priority needs in the EC. In accordance with its programme fully supported by its Advisory Committee of Programme Management (ACPM), JRC Geel set up elemental and isotopic working groups. In a continuing effort over the past years, and with the collaboration of national laboratories, nuclear industries and universities of the respective EC member countries, JRC-Geel succeeded in fulfilling the needs for a series of the most urgently needed NRMs.
