"The casks are more than adequate to prevent release in an accident."
- Probably.
But you have to "put it in" the cask first. That is the real accident issue
AFAIK.
Solar panels just need some R&D -- think about how long it will take to get approval and then construct a nuke plant. Then ask where photovoltaic solar will be in that time frame.
A panel on an LA roof also helps SHADE that roof - so you get a double benefit...
I am not likely to invest in anything nuclear - despite the incredible govt. subsidy for that industry.
But solar cells are looking like a growth industry.
