Safety requirements for waste packages, the basis for acceptance criteria of the KONRAD repository

Safety related requirements for the acceptance of waste packages due for final disposal in the repository planned for the Federal Republic of Germany in the KONRAD iron ore mine were derived from site-specific safety analyses. These requirements which will become part of future acceptance requirements were grouped as basic requirements which are independent of the activity inventory and activity inventory dependent requirements. With respect to activity inventories, two waste classes were defined. Waste forms within waste class I have to meet already relatively high standards and are further differentiated into six waste form groups. Waste forms of a higher activity inventory are correlated to waste class II, where the packagings have to be designed to resist incidents. The practical application of the requirements to several waste examples has been proven
