Not yet a headline issue, there is a real Brexit time bomb looming about Europe (the EU) doing its first new style review of all of Europe's existing nuclear power stations.
Required by the revised Nuclear Safety Directive of 2014, which is supposed to have been transposed into UK regulations, it is pathbreaking because for the first time ever it introduces peer group reviews of nuclear safety.
Previously, each country did its own, subject to a common guideline from the International Atomic Energy Authority. Now there will be a review of existing managed stations every six years, checked by experts from other countries.
The first review concentrates on key components in ageing nuclear stations, owned in the UK by EDF. Each country will do a report in 2017, then the "peer" bit starts, aiming to end in 2018.
Brexit and exit from Euratom, as we have already reported, wouldn't mean the UK can escape this process. But after that, with non-European nuclear owners and reactor designs, life might not be the same.
The revised Directive aims to improve public information about nuclear safety too. Will that survive after Brexit ?
