The aim of this research is to improve the reliability of the dynamic formula. This research program will concentrate on the proposal of a correction factor to adjust for this dynamic component similar to the damping parameter used in the Wave Equation Analysis and validate its reliability experimentally and theoretically. Similarly, the issue of the variation in the hammer energy delivered to pile needs to be improved by the adoption of new technology and validate experimentally.

This presents the advantage of decoupling the management of the minor actinides from the conventional fuel and not impacting the core reactivity coefficients. In both cases, the design and analyses of potential transmutation systems have been carried out in the frame of Gen IV fast reactor using a “perturbation” approach in which nominal power reactor parameters are modified to accommodate the loading of minor actinides.

(BQ) The adequate selection of manufacturing conditions is one of the most important aspects to take into consideration in the die-sinking electrical discharge machining (EDM) of conductive ceramics, as these conditions are the ones that are to determine such important characteristics as: surface roughness, electrode wear (EW) and material removal rate, among others. In this work, a study was carried out on the influence of the factors of intensity (I), pulse time (ti) and duty cycle (η) over the listed technological characteristics.
