Technical Meeting on Disused Sealed Radioactive Sources Disposal Options in Near Surface Disposal Facilities

14 – 17 Apr 2025
Vienna, Austria
Event code: EVT2404770

Event Information

A disused sealed radioactive source (DSRS) is a radioactive source, comprising radioactive material that is permanently sealed in a capsule or closely bonded and in a solid form, that is no longer used, and is not intended to be used, for the practice for which an authorization was granted. The international community has a well-developed set of guidance including categorization to safely manage DSRS. When a DSRS is declared as waste it should be managed in accordance with national requirements and eventually sent for disposal. 

The purpose of this meeting is to provide an opportunity for Member States to exchange knowledge on the disposal of DSRSs in near surface disposal facilities.
The following topics will be discussed during the meeting:
•    Case studies of DSRS disposal; 
•    Disposal of DSRSs similar to low level and intermediate level radioactive waste;
•    Inadvertent intruders; 
•    Disposal of DSRSs containing long lived isotopes; and 
•    Closure of the disposal facility.

A limited number of grants are available to support the attendance of selected participants provided that, in the IAEA’s view, the participant will make an important contribution to the event. There is no registration fee. 

In order to be designated by an IAEA Member State or invited organization, participants are requested to submit their application via the InTouch+ platform by 3 February 2025.

In addition to the registration through the InTouch+ platform, participants who wish to give presentations are requested to submit an abstract of their work. The abstract should be sent together with the Form for Submission of a Paper (Form B), to the competent national authority (e.g. Ministry of Foreign Affairs, Permanent Mission to the IAEA or National Atomic Energy Authority) or organization for onward transmission to the IAEA not later than 3 February 2025.
