Contribution to EURISOL WP5 – Legislation Legal limits for use of U-233 and Pu-239 in Germany related to EURISOL There are twp types of licensing in Germany for facilities dealing with major amount of radioactivity, a 'nuclear' one, which covers proliferation aspects besides general safety aspects, and a 'radiological' one, which deals with radioprotection only. The German atomic law contains the criterion for application of the 'nuclear' licensing procedure: Für die Anwendung von Genehmigungsvorschriften nach diesem Gesetz oder der auf Grund dieses Gesetzes erlassenen Rechtsverordnungen gelten Stoffe, in denen der Anteil der Isotope Uran 233, Uran 235, Plutonium 239 und Plutonium 241 insgesamt 15 Gramm oder die Konzentration der genannten Isotope 15 Gramm pro 100 Kilogramm nicht überschreitet, als sonstige radioaktive Stoffe. Satz 1 gilt nicht für verfestigte hochradioaktive Spaltproduktlösungen aus der Aufarbeitung von Kernbrennstoffen.

This means: A 'radiological' licensing is sufficient, if the total amount of U-233 and Pu-239... in the facility is smaller than 15 g, or if their mass fraction in the respective nuclide mixture is < 1.5 E-4. A 'nuclear' license is by far more complicated and requires intense involvement of the public. Experience shows, that the effort is at least an order of magnitude larger than in case of a 'radiological' licensing. Further, security measures taken for 'nuclear' facilities are much more extensive.

An Uranium or Thorium cladding of the power target in EURISOL with production rates for Pu-239 or U-233 in the range of 30 g/y can therefore not easily avoid a 'nuclear' licensing process in Germany.
