Abstract: Due to the C-1 4 distribution the separation of the particle - free outer region of the spherical HTR fuel element with subsequent solidification - of the separated carbon makes it possible to reduce by hal f the remaining C-1 4 inventory in the inner particle region to be further treated. Separation of the particle - free outer region by a newly developed sphere - peeling milling machine, conditioning the graphite into compacts and in-situ cementation into a salt-mine are the basic elements of this head-end process variation. An annual cavern volume of approx. 2000 m$^{3}$ will be needed to ultimately store the graphite of the particle - free outerregion, which corresponds to are processing capacity of 50 GW$_{e}$ installed HTR power. The brush-disintegration of the remaining inner particle region and the resulting peel-brush-crush-preparation are capable of separating 95 % of the graphite without any heavy metal losses. With the mentioned reprocessing capacity an annual cavern volume of approx. 16.500 m$^{3}$ is required .
