Franc e’s Nuclear Safety Authority (ASN) has doubts about EDF’s statements on financing of its decommissioning costs

Actu Environnement 12th July 2017 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

It 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 themain 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 NationalAssembly 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”.

Unlikemost 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.
