The Nuclear Safety Authority (ASN) considers that the EDF file concerning the financing of its decommissioning costs “does not provide sufficient information to enable it to take a position on the completeness of the assessment”. She would like the electrician to explain his calculations and reconsider certain assumptions. It also considers it necessary for EDF to present the reactor-to-reactor decommissioning assumptions, rather than an overall cost estimate extrapolated from the study of a site. This is the main conclusion of an ASN opinion on the financing of long-term nuclear loads by French operators published on Wednesday 12 July. This opinion comes as the level of provisions made up by EDF to cover the dismantling of its reactors is questioned. In February, a report from the National Assembly estimated that the dismantling costs calculated by EDF revealed a “plausible underestimation”. MEPs criticized among other things “the optimistic assumptions [and] a number of heavy expenses neglected”. Unlike most operators of nuclear installations, EDF does not present an installation-by-facility assessment. ASN can not therefore analyze the electrician’s file accurately. For the time being, EDF is relying on the “DA09” study, which assesses future loads by extrapolating a dismantling scenario for the four 900-megawatt reactors at the Dampierre (Loiret) plant. An audit requested by the ministry in charge of energy validated the method in 2015. However, the ASN refuses to rule on the accuracy of this figure since it did not have access to study DA09 or to auditing. In this case, the Nuclear Constable does not, as a matter of principle, oppose an assessment to the entire fleet of an assessment based on the dismantling of a reactor, but it wishes to have access to the documents before making a decision. Before validating EDF’s estimates, ASN wants to study precisely two points: the hypotheses considered for the dismantling of the Dampierre reactor and the extrapolation method at each reactor.

[Machine Translation] French nuclear power plants produced 197.2 TWh of electricity in the first six months of the year, reaching the lowest level since at least 2007 due to a large volume of planned and unplanned shutdowns, said Thursday EDF. Cumulative output is thus down 4% compared to the same period last year when it reached 205.2 TWh, and well below the record of 217.9 TWh recorded in 2011. The share of nuclear power In the French electric mix has nevertheless remained high, at around 73%. The public electrician was affected by a high number of shutdowns of its nuclear power stations this year following the discovery in 2016 of abnormally high carbon levels in the steam generators of 18 reactors, a dense maintenance program during the First half of the year and fortuitous unavailability in several reactors. In June, production was 26.9 TWh, down 5.9% from 28.6 TWh produced in June 2016, the lowest level since September 2016. Production was the lowest for A month of June since 2012 (26.6 TWh).
