During the 30 years of its existence, the Central Bureau for Nuclear Measurements has been involved in numerous high-accuracy investigations of mainly nuclear properties of elements important for the nuclear fuel cycle and for application of relevant radionuclides. These studies were made possible by the availability of particle accelerators (150 MeV electron linear accelerator; 3.7 and 7 MV Van de Graaff accelerators) as neutron sources and the use of specialised laboratories for the preparation, characterisation, and manipulation of radioactive samples. Examples of investigations with plutonium and neptunium described in this article include: (i) capture and fission cross-sections of 239Pu at very low energies; (ii) spontaneous fission fragment mass and energy distributions of 242Pu; (iii) alpha-particle and gamma-ray spectra of 237Np; (iv) half-life of 241Pu; (v) use of 237Np in reactor neutron dosimetry; (vi) the preparation and characterisation of plutonium oxide reference materials for nondestructive analysis; (vii) the demonstration of the potential of synthetic isotope mixtures for analytical control of the nuclear fuel cycle.
