...useful to future generations. As I understand it there's over 1500 tons of used nuclear fuel there.

Some of that fuel has had remarkably high burn ups, some of the best in the industry, meaning a pretty fair amount of valuable plutonium.

The spent fuel, as a rule of thumb, is generally about 95% unreacted uranium. Roughly 1% is reactor grade plutonium, the rest small amounts of fission products and transuranium actinides other than plutonium. This suggests that the energy content of this fuel alone is on the order of 100 Exajoules, enough to fuel the entire United States - all of its energy from coal, gas, oil, hydroelectricity, nuclear and the wilderness industrialized for solar and wind junk - for about a year or all of California for about 20 years. Under these circumstances - they are purely theoretical at this point - there would be zero air pollution in the State and lives would be saved.

Under circumstances where the fuel were used in process intensification situations, with high energy efficiency, the length of time to be covered would be longer.

This makes it an extremely valuable resource, and I expect that future generations will get it. Happily the fuel isn't going anywhere, and will remain available for wiser generations.

I always, when I drove past it, during my time in California, thought those reactors were quite beautiful. I don't know their current status as far as decommissioning goes, or whether they'd be suitable for restart.
