Matthias Dewald Chief Expert Decommissioning at Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) GmbH


After my master’s degree in nuclear physics in 2014, I started the position as scientific employee at GRS (Gesellschaft für Anlagen- und Reaktorsicherheit) in Cologne, Germany. Since June 2015 I work in the decommissioning and waste management division on the field of decommissioning. In 2018 I became team leader of the decommissioning working group. During my work I am involved in several projects supporting the German Federal Ministry for the Environment (BMU) as technical expert. Main topics are e.g. licensing of decommissioning projects in Germany and evaluation of decommissioning planning and strategies. Further I became project leader for scientific projects concerning questions such as determining heavy-to-measure radionuclides in reactor concrete and I participated in several national and international conferences and workshops over the last years. During my studies I worked mainly on the field of gamma-spectroscopy at different accelerator facilities in Germany and Japan.
