PG&E opting for Wind and Solar and dumping Nuclear Power

Better news regarding Nuclear Power being replaced by wind and solar ... no, not Germany, but in the US! 2016 Forbes Mag -- True story ...

So, who cares?  The most significant challenge at Hanford is stabilizing the 53,000,000 US gallons (200,000,000 l; 44,000,000 imp gal) of high-level radioactive waste stored in 177 underground tanks. 

Will PG&E keep their word?

Closing Diablo Canyon Nuclear Plant Will Save Money And Carbon

The CEO of one of America’s most prominent and technically capable utilities, Pacific Gas & Electric Company—previously chairman of the Nuclear Energy Institute and the Edison Electric Institute—just announced its decision (subject to regulatory approvals) to close PG&E’s well-running twin nuclear reactors at Diablo Canyon because they’re uneconomic and won’t be needed.
Unlike previous nuclear shutdowns, some of which were too abrupt for immediate replacement with carbon-free resources, PG&E’s nuclear output will be phased out over 8–9 years, replaced timely and cost-effectively by efficiency and renewables. That means no more fossil fuel burned nor carbon emitted, all at less cost to ratepayers. How much less? Natural Resources Defense Council (NRDC) says at least $1 billion (net present value to 2044).
PG&E also agrees that removing the inflexible “must-run” nuclear output, which can’t easily and economically ramp down much, will help integrate more renewable power reliably into the grid. Midday solar, rather than being increasingly crowded out by continued nuclear overgeneration, will be able to supply more energy. As Germany found, integrating varying solar and windpower with steady “baseload” plants can present challenges for the the opposite of the reason originally supposed: not because wind and solar power vary (demand varies even less predictably), but because “baseload” plants are too inflexible.
