Sustainability is more topical than ever, and nuclear technology shows a great potential to support the humankind both in near and longer term. 

SYP2022 follows the first and second events held in 2016 and 2019. This year’s event will again facilitate a face-to-face dialogue between nuclear science, industry and governmental bodies. The Symposium provides a timely and comprehensive picture of the intensive developments that are ongoing in Finnish nuclear technology: SMR development; re-licensing and commissioning; decommissioning and final disposal as a world-leader; plus much more.

The Symposium is international and open to all interested professionals, with special rates provided for ATS members with the support by ATS and sponsors.


Date: 1-2 November 2022

Location: Paasitorni Congress Center, Helsinki, Finland
