Hybrid reactors with magnetic confinement. Preliminary analysis and calculational model

Begining with a general revision of the technical concepts a great amount of calculations on typical geometrical configurations is given, comparing these results with those found in the references. So, we obtain the validation of our own methods, and important experience on the sensitivity of different effects in the hybrid system. Is our main interest the analysis of the blanket as energy multiplier and breeder of tritium and fissionable material. The calculations are focussed on heterogeneous and homogeneous blankets. The initial work is centered in UO2 and UC fuels, with 1 m total thickness of the blanket. It seems that, thicknesses of 20 or 30 cm of the fueled zone in the internal position are good enou.o.h to obtain interesting hybrid solutions. Other solutions, as U3Si fuels, are considered. (author)
