¹ Ra­dio­act­ive waste ex­clus­ively con­tain­ing ra­di­o­nuc­lides with a half-life of 100 days or less must, whenev­er pos­sible, be re­tained at the sites where it arises un­til its activ­ity has de­cayed to such an ex­tent that it can be meas­ured for clear­ance in ac­cord­ance with Art­icle 106 or dis­charged with­in the li­censed dis­charge rate in ac­cord­ance with Art­icle 112 para­graph 2.

² In the ab­sence of an al­tern­at­ive that is more fa­vour­able over­all for people and the en­vir­on­ment, ra­dio­act­ive waste whose activ­ity, as a res­ult of ra­dio­act­ive de­cay, will have de­creased no later than 30 years after the end of use of the ori­gin­al ma­ter­i­al to such an ex­tent that it can be meas­ured for clear­ance in ac­cord­ance with Art­icle 106 or re­cycled in ac­cord­ance with Art­icle 115 must be stored un­til this point has been reached. It must be sep­ar­ated from ra­dio­act­ive waste which does not ful­fil this con­di­tion.

³ Dur­ing the de­cay peri­od, waste as spe­cified in para­graphs 1 and 2 must be:

a.

pack­aged and stored in such a way as to pre­vent the un­con­trolled re­lease of ra­dio­act­ive sub­stances and avoid cre­at­ing a fire haz­ard;

b.

marked and provided with doc­u­ment­a­tion in­dic­at­ing the type of waste, activ­ity con­tent and time of pos­sible clear­ance.

⁴ Pri­or to clear­ance, it must be en­sured that Art­icle 106, or Art­icle 112 or 115, is com­plied with.

⁵ The li­cens­ing au­thor­ity shall spe­cify the tech­nic­al re­quire­ments for de­cay stor­age and any re­lated activ­it­ies.³⁹
