NUCLEAR MEASUREMENTS AND REFERENCE MATERIALS
This is the first report pertaining to the 1984 - 1987 JRC Geel - CBNM project on nuclear measurements and reference materials. In its subprojects: nuclear data and nuclear metrology, and nuclear and non-nuclear reference materials respectively, progress has been made as follows: High resolution data have been collected for neutron induced reactions, and it has been proven that the earlier investments made to compress neutron pulses at Linac and Van de Graaff were well founded. Selected experimental measurements and extensive evaluation have been made of the thermal neutron constants of 233-U, 235-U, 239-Pu, and 241-Pu, and the fission neutron yield of 252-Cf. The decay of 241-Pu was determined accurately. A series of existing non-neutron nuclear data was re-evaluated and tables newly published. Steady progress was made for the preparation and characterization of basic reference materials for nuclear energy. Important here is the certification of a uranium oxide material to be used as reference for the determination of the 235-U content by gamma spectrometry. In the new fields tackled, progress was made in neutron dosimetry (production of detectors for dosimetry in reactors and for medical applications). The 1984 programme is marked by an increase of the ratios fusion data - fission data and non- nuclear reference materials - nuclear reference materials.
