    A review of the Belgian Research Activities on Nuclear Reactor Pressure Vessel Steels and on related Neutron Dosimetry Aspects is presented. Born out of the surveillance programmes of the Belgian NPP's, this research leads to the development of material-saving techniques, like reconstitution and miniaturisation, and to improved neutron dosimetry techniques. A physically-justified RPVS fracture toughness indexation methodology, supported by micro-mechanistic modelling, is based on the elaborate use of the instrumented Charpy impact signal. Improved computational tools for neutron dosimetry, validated on basis of benchmark experiments, allow to reduce the uncertainties on surveillance capsule and pressure vessel fluences significantly.
