3 Chapter 1 January 28th and 29th, 2015 Basic remarks to decommissioning and dismantling (D&D)

4 D&D key challenges Difference between D&D and other nuclear activities The 3 main challenges in nuclear technology 1. Control criticality Keep the core reaction under any condition under control Tschernobyl 1986 Loss of criticality control 2. Establish long time cooling Guarantee the long term cooling of the core under any condition Fukushima 2011 Loss of long term cooling 3. Avoid spreading of contamination outside the plant Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 4

5 The remaining D&D key challenge Avoid spreading of contamination factor factor factor Plant shut down ~ 1 E21 Fuel unloaded Full System Decont. performed ~ 1 E17 ~ 1 E13 ~ 1 E10 Activity inventory of a NPP [Becquerel] Activated inventory dismantled Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 5

6 Current status Shut down power plants don t earn money any more, they remain to be a risky item in the balance sheet of utilities only For the decommissioning and dismantling (D&D) of those plants it means: 1. It has to be as cheap as possible while not endangering the last nuclear request not spreading contamination 2. Industrial risks have to handled in a foreseeable way 3. The focus will be (waste) logistics 4. Many comparable D&D projects are planned for the coming decades there is no reason to handle each of them like a single project Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 6

7 Chapter 2 January 28th and 29th, 2015 The fleet approach how to make D&D cheaper and faster

8 From project to product During the build of the German nuclear fleet the KONVOI concept had been elaborated: Build standardized plants in order to be most efficient Transferred to D&D it would mean to standardize: Processes to prepare for D&D Equipment to a maximum extent Engineering to a maximum extent Licensing approaches and regulatory affairs Teams on site In order to: Make it cheaper by reusing equipment, engineering and licensing Learn from plant to plant to continuously improve efficiency Make out of a series of projects a serial production Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 8

9 Fleet application to the 6 key areas Regulatory monitoring and controls Dismantling Operations Dismantling strategies and scenario Fleet approach Site management and operations Waste management & logistics Supply chain 2 3 Implementation of a common approach for each of the key areas to be continuously improved with every new project 4 Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 9

10 Purchase of common equipment-sets for standardized dismantling Reused equipment is depreciated over several usages which reduces equipment cost in each single project tremendously Strong design to survive several usages Design to cover several different plant designs Design suitable for decontamination and transportation The equipment suppliers need to be sustainable over a long period of time in order to continuously provide spare parts and services Cost savings of about 30% compared to a standard project are reachable Fleet application Supply chain Example: Dismantling of RPV-Internals Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 10

11 Fleet application Regulatory monitoring and controls One of the KONVOI key savings was the regulatory approach: Split of responsibilities (scope) between the independent experts (IE) involved Each IE accepted the results of the other IE s for there part of the scope The licensing authorities of the states supported this approach Beside others this lead to a construction time of the KONVOI plants of less than 6 years Could this excellent lesson be transferred to D&D? But It would be ideal to do it accordingly It will be difficult to reach a political agreement regarding such an approach these days Common licensing approaches could make D&D much faster Even a general common understanding between the IE s involved would improve the situation clearly At least a common information body not heaving decision authority could be helpful Further development of a common licensing concept over the coming years should be targeted Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 11

12 Summary D&D is far more a industrial challenge than a nuclear one Handling D&D as a serial production instead of a series of projects will improve performance and cost efficiency a lot The car industry did prove this statement over the paste century Fleet approach Krüger - January 28th and 29th, 2015 AREVA Proprietary - RESTRICTED AREVA - p. 12
