As far as I can tell decommissioning has started so someone has to draw up the scheme to halt that process, develop a scheme to renew the license and the restoration of commissioning activities and last but not least find a fabricator able to fit fabrication of new fuel assemblies into its production schedule without delaying other jobs already on order.
I would think that we are talking about dollars here that Newsom will have to fight with competing interest for dollars from Biden's bill as well as go to a legislature bound and determined to forge ahead with wind and solar and probably very reluctant to budget funding for standing up Diablo Canyon. Maybe the idea of a desalinization plant in conjunction with keeping Diablo Canyon running would help the cause as that would be much less expensive than the Sacramento reconveyance plan.
