14th International Symposium
Release of Radioactive Materials - Provisions for Clearance and Exemption
Seminar-Nr.: 50207201
Termin auswählenDer Nutzen im Überblick
Scope of the Symposium
Since 1998 TÜV NORD has been organizer of various symposia dedicated to the “Release of Radioactive Material from Regulatory Control”. During the previous international symposium in Frankfurt in 2022 more than 150 clearance experts were welcomed to contribute to the discussions of this issue, which due to huge decommissioning projects moves in the focus of public interest. These interchanges of experience help to optimize release procedures and to reduce the amount of radioactive waste. In November 2026, we would like to continue the fruitful exchange of experience.
From the very beginning in 1998, the symposia have followed up the change of international regulation and guidelines in the area of clearance. Currently, the new IAEA Safety Guide DS500 on the “Application of the concept of clearance” is in the process of endorsement and will update and supersede the previous Safety Guide RS-G-1.8 “Application of the concept of Exclusion, Exemption and Clearance”.
Considering this highlighted starting point, we invite you, as interested experts from many countries, to continue the exchange of experience, expertise and information in the field of clearance. TÜV NORD will organize a symposium, which is intended to take place on 17th - 19th November 2026 in the Hotel Melia in Berlin. We would be pleased to welcome you to the Get Together on the evening of the 16th November 2026.
It is planned that proceedings will be available at the beginning of the symposium. If you are interested in submitting a paper in attending this symposium, please contact our Organization-Team: tagungen@tuev-nord.de
