The JRC is decommissioning nuclear research facilities at four sites - Karlsruhe, Geel, Petten, and Ispra - under the Nuclear Decommissioning & Waste Management Programme. The programme, launched in 1999, will span four decades.
The European Parliament and the Council have promoted a series of initiatives to share the knowledge gained from ongoing nuclear decommissioning programmes (NDAP) across Europe. The goal is to leverage this expertise to support future decommissioning projects. To achieve this, the European Parliament and the Council have entrusted the JRC with leading the Nuclear Decommissioning Knowledge Management (NDKM) Initiative.
The JRC manages the knowledge gained in the EU-funded or co-funded decommissioning programmes under this initiative. Since 2021, the NDKM Team is supporting the development of knowledge products. A knowledge product is a tangible output of prepared knowledge that enables action of selected users. This web section presents the latest version of the currently available knowledge products.
