Characterisation and fabrication of zirconia and thoria based ceramics for nuclear applications

The reduction of the long term radiotoxicity of nuclear waste during disposal is the aim of the research called ''Partitioning and Transmutation of Minor actinides (MAs)'', which also requires the development of inert ceramic support materials. Moreover, after separation, if the transmutation is not available, the actinides can be conditioned into stable dedicated solid matrices (Partitioning and Conditioning strategy).

860^Data from three experiments using the heavy-ion fusion evaporation-reaction 36Ar+28Si have been combined to study high-spin states in the residual nucleus 60Ni, which is

populated via the evaporation of four protons from the compound nucleus 64Ge. The GAMMASPHERE array was used for all the experiments in conjunction with a 4 chargedparticle

detector arrays (MICROBALL, LUWUSIA) and neutron detectors (NEUTRON SHELL) to allow for the detection of rays in coincidence with the evaporated particles. An

extended 60Ni level scheme is presented, comprising more than 270-ray transitions and 110 excited states. Their spins and parities have been assigned via directional

correlations of rays emitted from oriented states. Spherical shell-model calculations in the fp-shell characterize some of the low-spin states, while the experimental

results of the rotational bands are analyzed with configuration-dependent cranked Nilsson-Strutinsky calculations.

IAEA

COMMON ERRORS IN CATEGORIZATION

• S74: Atomic and molecular physics• S74 instead of S73

Do not use for every document containing word “atom” or “atomic”– in many cases it is nuclear physics

• S74 instead of S37

Do not use for chemistry – the word “molecule” could be misleading

• S43: Particle accelerators• S43 instead of S62 – for radiotherapy at accelerator facility

• S43 instead of S36 – for materials

• S43 instead of S72 – for elementary particles

• S43 instead of S71 – for production of electron, ion, atomic and molecular beams other than in accelerators

COMMON ERRORS IN CATEGORIZATION

• S72: Physics of elementary particles and fieldsIncorrectly used when in a document some elementary particle is mentioned

• S72 instead of S73

Do not use for every document discussing elementary particles (in many cases this is wrong); Ex. Interacting Bosons Model (IBM) – nuclear models; nucleons in nuclear structure; nuclear potentials. Do not use for nuclear reactions and spectroscopy

Do not use for classical relativity theory

• S72 instead of S75

Do not use for models in condensed matter physics; Ex. Phonones

COMMON ERRORS IN CATEGORIZATION

• S54: Environmental Sciences• S54 instead of S37

• S12: Management of radioactive wastes… should be used for the management of all types of radioactive wastes and for

non-radioactive wastes generated by nuclear facilities only

• Other particular categorization aspectsSuperconductors
