Besides the plans for extension of life of the plant etc. they were needing to do a scheduled shutdown which they needed to shut a reactor down (which I believe they have initiated)
As I understood it they’re shutting down anyway, for refuelling I think? The extra work has been postponed because very little of the prep work is done.
So they’ll refuel as planned and then do the other work “later”. But that work will probably not be done by the time for the regulatory shutdown.
Th admin processes needed for re-approving a lapsed / shutdown plant to start up again is much more onerous than getting the extension while the plant is still licensed, but it looks like that’s the way we’re heading.
Might end up impossible to restart due to the bureaucracy, but that doesn’t really make sense on a technical level.
