"According to NPR, they have 90% of the 2 billion dollars necessary to decommission the place in a fund."
NPR needs to do better research. Actually they have close to $3 billion in the fund, toward an estimated cost of $3.2 billion. The chances of it only costing $3.2 billion are slim and none, and slim has left the building, because that cost is based on finding an existing site for offsite relocation of the spent fuel (i.e Yucca Flats), and no such place exists.
SouCal barely squeaked by last year on power during a couple of warm spells, and since then two sizeable fossil fuel generating stations in Newport have lost their licenses, so things are going to be very dicey if we have even a normal summer, let alone a hot one. The Sunrise Power Link will not be of much use without voltage support from generating sources in SouCal.
It was probably a good decision, but it will come with costs.
