Policy Department D: Budgetary Affairs ____________________________________________________________________________________________ Lithuania Cost estimation of the decommissioning at Ignalina is in detail described in Harrison 2012. The estimate is based on: The Final Decommissioning Plan; A simplified model of the project, but including all project stages and cost-relevant factors; Greifswald data; 2011 prices, 2029 macroeconomic adjustment and cost escalation of technical risks. Figure 42 shows the main results of the estimate by action type (upper part) and over the time periods (lower part). Figure 42: Cost structure by activity and by phase Source: (Harrison 2012) The results are well compatible with EWN analysis. According to Harrison 2012 this latest estimate differs only insignificantly from previous estimates. All in all, the recent cost estimate is state-of-the-art. Slovakia In 2006, at the beginning of the decommissioning project a long term costs analysis was developed. A more comprehensive cost analyses was later prepared and reviewed by external bodies. The Bohunice V1 NPP Decommissioning Cost Analysis that identified the costs needed was developed in 2011 (Aid 2013). The analysis was based on the key documentation 'Conceptual decommissioning plan', 120
Nuclear Decommissioning: Management of Costs and Risks ____________________________________________________________________________________________ as performed in cooperation with EWN (see ANNEX 5). This analysis identified that there is a substantial need for further funding of EUR 300 million of the V1 NPP Bohunice decommissioning process at that time. The most recent cost analysis estimated the total costs for the decommissioning from 2003 until 2025 to be EUR 1 141 million (including the spent fuel wet storage costs).The direct decommissioning costs sum up to EUR 868 million and the costs incurred due to premature shutdown to EUR 273 million respectively (JAVYS 2013). The costs due to premature shutdown were calculated as follows (JAVYS 2013): The V1 nuclear power plant (which is made of two units) should normally have remained in operation until 2015. But as mentioned earlier the Unit 1 was shut down in December 2006 and the Unit 2 in December 2008 respectively. A National Nuclear Fund for Decommissioning (NNF) was established in 2006 according to the Act No. 238/2006 Coll. (Act 2006, see also chapter 4.3.1). So the operator paid contributions to the NNF until to December 2006 for the operation of the two blocks and only for the remaining block until December 2008. The overall estimated costs and their share to different resources are shown in Figure 43. The EU pays the decommissioning costs firstly to the Bohunice International Decommissioning Support Fund (BIDSF) which is administrated by EBRD. This total financial support is about EUR 348 million. The BIDSF further covers the costs of EUR 100 million which are not granted. Figure 43: The overall costs divided according to the financial resources and taking into account the expenses being still not covered Source: (JAVYS 2013) National resources need to cover the costs of EUR 363 million. Additionally about EUR 200 million will be supported by EU from 2014 until 2020. A remaining gap of EUR 129 million is still not covered. Due to development of several strategies how to cover the costs and/or due to a more accurate cost estimation the aforementioned estimated remaining gap of EUR 300 million was reduced. According to JAVYS 2013 the relation between the costs covered by BIDSF and NNF shifted from 54 %/46 % (BIDSF/NNF) in 2011 towards 42 %/59 % (BIDSF/NNF) in 2012. 121
