Entsorgungswerk für Nuklearanlagen

What Entsorgungswerk für Nuklearanlagen does

EWN Entsorgungswerk für Nuklearanlagen GmbH is a 100% federally-owned German company mandated with the decommissioning, dismantling, and disposal of nuclear power plants and radioactive materials. Its primary operations cover the dismantling of the Greifswald/Lubmin nuclear power plant (5 reactor units) and the Rheinsberg nuclear power plant (1 reactor unit), together with the operation of the Interim Storage Facility North (ZLN) — an eight-hall facility currently holding 74 CASTOR transport and storage casks containing irradiated fuel and radioactive residues. The technical core consists of remote-controlled disassembly facilities (wet and dry), the Central Active Workshop (ZAW) for conditioning radioactive waste, the Central Decontamination and Water Treatment Plant (ZDW), and a clearance measurement facility (Freimessanlage) that enables roughly 75% of dismantling materials to be conventionally recycled. The company also operates ancillary infrastructure including a closed electricity grid and railway facilities at the Lubmin site, and is planning the ESTRAL replacement storage building to address post-2011 security requirements for CASTOR storage.

The company's go-to-market is split between (i) a government-commissioned core mandate funded directly by the Federal Ministry of Finance as sole shareholder and grantor, and (ii) a third-party services line procured via formal tendering (bund.de, ted.europa.eu) and direct negotiation with public nuclear authorities and private energy operators. The EWN Group also encompasses two wholly-owned subsidiaries — Jülicher Entsorgungsgesellschaft für Nuklearanlagen mbH (JEN, Jülich) and Kerntechnische Entsorgung Karlsruhe GmbH (KTE, Karlsruhe) — which handle dismantling of research and prototype nuclear facilities in North Rhine-Westphalia and Baden-Württemberg respectively. Pricing is not publicly disclosed; revenue mechanics are dominated by federal appropriations rather than commercial pricing. Customer segments are concentrated on the German federal government, with secondary exposure to state-level nuclear regulators and private nuclear facility operators.

Core offering

EWN is a 100% federally-owned German company that performs the complete decommissioning, dismantling, and disposal of former East German nuclear power plants at Greifswald/Lubmin and Rheinsberg. Its core offerings include immediate dismantling of reactor units, interim storage of nuclear fuels and radioactive waste in the Interim Storage Facility North (ZLN), decontamination and conditioning of radioactive materials through the Central Active Workshop (ZAW) and ZDW water treatment plant, and radiation protection services. The company also provides third-party decommissioning services to public authorities and private nuclear operators nationally and internationally.

Product overview

EWN Entsorgungswerk für Nuklearanlagen GmbH is a German federal company responsible for the decommissioning, dismantling, and disposal of nuclear power plants. The company's portfolio consists of two core product lines: nuclear facility dismantling services (including the Greifswald and Rheinsberg nuclear power plants) and interim storage solutions for radioactive materials. Supporting these core offerings are specialized services including decontamination, radiation protection, conditioning, and clearance measurement. Key facilities include the Interim Storage Facility North (ZLN) for storing nuclear fuels and radioactive waste, the Central Active Workshop (ZAW) for processing solid radioactive waste, and the ZDW water treatment plant. The company also operates auxiliary infrastructure including an electricity grid and railway facilities on its site. Services are offered both for internal EWN Group facilities and for third-party nuclear clients.
