NUCLEAR ANALYSIS FOR THE LIGHT-ION FUSION POWER-REACTOR LIBRA-SP

A 1.2 m thick zone of blanket tubes is needed for the LIBRA-SP chamber wall to be a lifetime component. The roof should be located at 17 m f rom the target to be a lifetime component. The depth of the LiPb pool should be 0.6 m for the bottom plate to be a lifetime component. The r equired biological shield thickness is 2.5 m on the side and 2.6 m at the top. The overall TBR is 1.435 and the overall energy multiplicatio n is 1.18. The diode casing as well as the cathode and anode feed bus- bars are lifetime components. If ceramic insulators are used in the ma gnet coils, they will be lifetime components. If organic insulators ar e used, the coils have to be replaced once in the life of the reactor.
