because you stupidly make your own definition of "spent fuel" ignoring what the commercial nuclear power industry calls "spent fuel". The spent fuel in cooling ponds and casks is 96% fissionable and/or breedable fuel that can be used in a properly designed reactor.
You are very ignorant.
"Spent fuel" from U.S. commercial reactors contains 94 percent U-238, 0.9 percent U-235 and 0.8 percent pu-239. ALL of that can be "burned" in a properly designed reactor, and moreover long-lived isotopes from those reactions can be converted to short lived ones.
it's really sad to see comments from those who can't accept reality, you'll live less than nine decades and die. your imagination will not help you, technology will not change this.
Even in greco-roman times people who took care of their health lived into their 70s.
generational starships or just time dilation by going near speed of light, don't need longer lifespan for space travel
cleaner nuclear power is solved problem, we already know how to make reactors that can burn "spent fuel" and leave waste that decays in decades rather than millenia. smarter countries are pursuing that, but the USA just extended life on its 2nd gen reactors that were designed in the late 1950s, can melt down if not externally cooled, and make waste that will last longer than any civilization has.
actually, those Hebrew writer in the Bible had more accurate calendar than we do, lunar calendar (e.g. Chinese, Jewish) trumps solar one
I was only addressing situation in USA.
but that fibre aren't yet available with iridium plating on the connectors for crisp bright treble
why do you hate them so much? A legitimate target for atomic bomb could have naval bases such as Yokosuka. but you prefer tens of thousands of incinerated civilians.
I must say these 800GB fiber bundles give very molten and sonorus bass notes below 64 hz.
wrong, bottom line is the tests have been "dumbed down" over the years, your closing gap of women's scores is due to that
and your parents are lightyears ahead of this fossils who have never used a PC
and let's hear about those foreign designers of the Rocketdyne F-1 engine, let's see if it matches my list of americans who managed, designed, built and refined the design of that engine
yes, you can add those things to list of about 30 other config changes and call the paper "How to Make Windows 8.x not so Much of a Pig"
Not an undertaking for your Aunt Minnie or Grandma
nope, making nuclear fuel from Ukraine's uranium was and is done by TVEL in Russia. The reactors are TVEL's also.
