Decommissioning of the THTR-300 facility is completed in 5 steps, beginning with the unloading of the spherical fuel elements from the reactor core, proceeding then to the ``Safe Enclosure `` of the facility, and ending with its total removal and transforming the site into a greenfield. To complete the various decommissioning measures, it is necessary to proceed according to the following time schedule: ca. 1.5 years for core unloading, ca. 1 year to ensure ``Safe Enclosure``, and then 30 years under ``Safe Enclosure``. While ``Safe Enclosure`` is being accomplished, 700 tons of solid, residual material are removed. Due to the fact that no ultimate repository is operated in Germany, this material is stored in the THTR-300 facility until its total demolition and removal. Combustible and liquid waste material is being disposed of in other, external facilities.
