Abstract

Since 1983 the Karlsruhe Nuclear Research Center is investigating the technological problems of helium cooled ceramic blankets for fusion reactors. Various solutions have been so far investigated: poloidal, toroidal or lobular arrangement of the pressure tubes containing the breeder material and the cooling of helium; lead multiplier integral with the first wall or beryllium in the ceramic breeder region. For all these designs it is crucial to maintain the tritium losses from the plant equal or below 10 curie/d. This requires a helium purge flow completely separated from the main helium coolant flow.
