1 DECOMMISSIONING INCLUDING FINANCIAL PRECAUTION Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management Second Review Meeting May 17 th, 2006 Dr. Michael Paul Dr. Karl-Heinz Kölschbach Federal Ministry for the Environment, Nature Conservation and Nuclear Safety Bonn, Germany Dr. Jörg Kaulard Sven Dokter Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) mbh Cologne, Germany 1 Contents Overview of decommissioning in Germany Legislative framework of decommissioning Financing of decommissioning of nuclear installations 2 1

2 Overview of Decommissioning in Germany (1 / 5) Prototype Power Reactors and Nuclear Power Plants shut down, under or yet removed Prototype Power Reactors (total of 7 units) - removed: 2 - safe enclosure: 1 - : 4 Nuclear Power Plants (total of 12 units) - removed: none - safe enclosure: 1 - : 10 - final shut down / application for license: 1 3 Overview of Decommissioning in Germany (2 / 5) Research Reactors (total: 33 facilities) Removed: 21 - Critical assembly: 8 - Argonaut type: 4 - Liquid homogeneous reactor: 3 - Propulsion reactor: 1 - Educational reactor: 5 Safe enclosure: 2 Partially removed: 1 Dismantling: 7 Shut down / application for license: 2 4 2

3 Overview of Decommissioning in Germany (3 / 5) Nuclear Fuel Cycle Facilities Prototype Facilities (total of 3 units) - Completely dismantled and released: 3 Commercial Facilities (total of 6 units) - Completely dismantled and released: 2 - Completely dismantled but not yet released: 2 - Dismantling: 2 5 Overview of Decommissioning in Germany (4 / 5) Kernkraftwerk Stade Recent decommissioning project decommissioning of Stade NPP Basis features on Stade NPP - Reactor type: PWR - Electrical power: 662 MWe - Operation: Operator: Kernkraftwerk Stade GmbH & Co. ohg Decommissioning - Decision on decommissioning based on economic reasons - Decommissioning option: immediate with green field condition - Release from regulatory control expected for early In parallel: construction and operation of interim storage facility for radioactive waste from decommissioning 6 3

4 Overview of Decommissioning in Germany (5 / 5) A Four Phases Approach for Stade NPP operational phase post - op. phase residual operations and calendar year licensing of and supervision on the decommissioning phase 1 phase 2 phase 3 of non-nuclear facilities phase 4 release from regulatory control conventional licensing of and supervision on the interim storage facility for radioactive waste (LarA) : Application for decommissioning (phase 1) and LarA year of decommissioning : License on decommissioning (phase 1) and on LarA : License on decommissioning (phase 2) : Final shut down Legislative Framework of Decommissioning German Constitution (GG) Atomic Energy Act (AtG) Other acts, e.g. UVPG (Environmental Impact Assessment Act), BauGB Ordinance on Radiation Protection (StrlSchV) Ordinance on the Nuclear Licensing Procedure (AtVfV) Other ordinances, e.g. EndlagerVlV 8 4

5 Decommissioning - relevant installations All nuclear installations require a license for operation according to Section 7 para. 1 Atomic Energy Act (AtG) and after final shut down a license for decommissioning and or safe enclosure according Section 7 para. 3 Atomic Energy Act (AtG) Nuclear installations are: Prototype power reactors Nuclear power plants Research reactors Nuclear fuel cycle facilities 9 Prerequisites for a Decommissioning License Reliability and knowledge of the applicant and other persons involved Precautions in the light of the state of the art in science and technology to prevent damage Financial security to pay compensation for damage Protection against disruptive action or other interference by third parties 10 5

6 Financing of Decommissioning - Responsibilities Polluter-Pays-Principle Privately owned facilities, particularly NPPs: Decommissioning is financed by the operating companies Estimated costs for decommissioning of NPPs: 0.5 to 1 Billion Euro per nuclear power plant totally: approx. 25 Billion Euro needed Publicly owned facilities, particularly research installations: Decommissioning is financed by annual budget of the State 11 Financing of Decommissioning of Privately Owned Nuclear Installations Necessary financial means are provided in the form of provisions Provisions are built up during the operational phase in accordance with commercial law 12 6

7 Building up of Provisions (1/2) Provisions are intended to cover costs for: Decommissioning and including the management of waste from Management of radioactive waste from operation Management of spent fuel Total amount: > 32 Billion Euro 13 Building up of Provisions (2/2) Sec. 249 HGB: provisions have to be built up to cover liabilities that are unsure concerning the amount, the time of occurrence or the asset but that can be expected to a sufficient degree of certainty Provisions are reported in the operator s balance sheets No specific rules for the nuclear branch 14 7

8 Financing of Decommissioning - Conclusions The German system of financing the decommissioning process has proved to be successful The changing conditions in the nuclear power scene, such as Nuclear phase-out Competition in the electricity market Privatization of power utilities may require reconsideration of the existing funding system General requirements concerning the financing of decommissioning: Adequacy Availability Transparency 15 Thank you for your attention!
