13 Political decisions in Germany after Fukushima 14th March 2011: - 3 month moratorium on 8 NPP - 2 commissions started their work for a safe energy supply - Reactor Safety Commission (RSK) - Ethic commission: 17 members from the realms of politics, business, civil society and the churches 30th June 2011: - The Reactor Safety Commission found no weaknesses in the NPP. Therefore only the results of the Ethic Commission had influence on the New Atomic Energy Act : Phase out of the NPP Slide 13

16 Decommissioning and energy transition in Germany 2011: Germany before and after Fukushima Phasing out in Germany: New challenges 2017: Status of the Phasing out project Challenges in the phase out Slide 16

17 Challenges in 2011 for NPP Start from a scratch no preparation time for post operational phase and decommissioning Safe enclosure? or immediate decommissioning? Licensing procedures Many licensing procedures at the same time Lack of experience Large experience with decommissioning of research reactors little experience with decommissioning of commercial reactors (only NPP Stade, NPP Obrigheim) Insufficient infrastructure Of waste management and storage for decomm. of all reactors. Are there suficent cask available? Is the organisation structure ready for decomm.? Clearance Releasing material into environment acceptance in the public? Parts of the public are against nuclear energy Slide 17

18 Post Operational Phase and Decommissioning First steps Decommissioning a NPP is a cost- and time-consuming project Therefore it is important to consider as soon as possible first steps Important points to be considered to ensure the safety of the NPP, to be prepared for the post-operational phase to be prepared for the initiation of the licensing procedure. A NPP in the Post-operational or decommissioning phase produces no income Efficient implementation of the first steps offers the possibility to reduce costs Slide 18

19 Post-operational phase and decommissioning First steps Which systems are no longer needed? => Classification of NPP systems: Important / Needed for operation during decommissioning / no longer needed Which systems are needed with spent fuel in the NPP? => Protection of these systems Which old / new systems are needed for decommissioning => Update of specifications Which rules and regulations should be considered? => Operational experience from other projects Which training is needed? => Different training courses Which organisation form is helpful for decommissioning? => Efficient organisation structure Slide 19

20 Post-operational phase and decommissioning First steps Work during the post-operational phase => Shutdown of systems no longer needed => FSD and other decontamination Radiological characterisation => Important data for decommissioning and waste management Reduction of inventory => Waste from operation during post-operational phase => Waste from decommissioning during decommissioning phase => Full system decontamination and other decontamination steps => Spent fuel management, Full system decontamination Defueling => Which cask? => Handling of spent fuel => Handling of problematic spent fuel Slide 20

21 activity Measures in the post-operational phase Suggestion of ESK guidelines to decommissioning of nuclear plants Inventory inflammable (yes/no)? toxic (yes/no)? Water Law relevant relevant (yes/no)? Set up of nuclear fuel freedom Reduction of radioactive inventory Implementation of an inventory taking Decommissioning of no longer needed installations Radiological characterisation of the entire plant Slide 21

29 Commission on review of the financing of the phasing out of nuclear energy (KFK) Start of the commission 19 members from the realms of politics, business, civil society and the churches Review on the financing of the costs for decommissioning, waste management and final storage Results Costs for decommissioning and waste treatment are payed by the owners of NPP Costs for final storage is paid by the state, but about 24 billions are paid by the owner in 2017 to the state Slide 29

31 The search after a final repository Many years of political discussions and massive protests of parts of the public against Gorleben: - Political decision to stop Gorleben - Restart of the search for a site of a final repository - White map with no prefered sites - Clear and transparent public process - Involvement of a large variety of the public, not only technicians or politicians. Slide 31

32 Public committee regarding final repository for HLW 33 (34) members in this commission, - 2 chairs, - 16 members from the politics, - 8 members from the science - 8 members from the civil society (in each case 2 members from environmental associations, religious groups, economy and labor unions). Only the 8 members from the science and the 8 members from the civil society have the power to vote in this committee. Slide 32

33 Public committee regarding final repository for HLW The committee had to prepare proposals: - to assess and decide whether other possibilities for the proper disposal of this waste exist - for decision-making (general safety requirements for the storage) - for criteria for possible error correction - for requirements for participation and information to the public, measures to ensure transparency - to assess international experience The commission started in 2013, the final report was presented in The results of this final report are considered in the revision of the site selection law (Standortauswahlgesetz). The next step will be the evaluation of possible sites. These steps will also be accompanied by a new public committee. Slide 33

37 New grid connections needed Insufficient grid connections New grid connections needed because of Decentralised production Different sorts of renewables (wind in the north of Germany, solar in the south of Germany) Enhanced need for controlling the grid Amount of re-dispatching was increasing, but should now be stable Slide 37

40 Conclusion The energy transition and the phase-out of NPP in Germany is on its way. During the last 6 years Germany has managed many challenges, but there are still many points to handle. The energy costs can hopefully be stabilized, but the costs for building up renewables are very high. The situation in South Korea can be compared with the situation in Germany after Fukushima. But the starting point seems to be different in some points. Slide 40
