As an added bonus, many of the very long - lived nuclides
larger than Uranium (Neptunium, Plutonium, Americium, Curium, etc.) have the same trend, and fast reactors can split and destroy these actinides as fuel rather than let them accumulate as in thermal reactors.
Not exact matches
The world's ample supply of
uranium could fuel a much
larger fleet of reactors
than exists today throughout their 40 - to 50 - year life span.
And by 2070, Storm van Leeuwen found, the amount of energy it takes to mine, mill, enrich and fabricate one metric ton of
uranium fuel may be
larger than 160 terajoules — the amount of energy one can generate from it.
The
larger particles also adsorbed
uranium more slowly
than the smaller ones.
The team found that gravel and other
large bits adsorbed less
uranium (IV)
than smaller grains.
In contrast, super-Earths with a similar concentration but
larger absolute amount of radioactive heat sources (i.e.,
uranium and thorium)
than Earth would produce more internal heat, more vigorous mantle convection, and faster plate tectonic action involving thinner plates, which may promote planetary habitability with lower mountain ranges but higher volcanic activity and an atmosphere with a greater relative composition of volcanic and lighter gases (Sasselov and Valencia, Scientific American, August 2010; Valencia and O'Connell, 2009; and Valencia et al, 2007).
By installing a
large PV solar nameplate capacity, using the need to pay off this (subsidized) investment as the rationale for approved rate increases, and then selling us (mostly) the cheaper electricity they make from coal and
uranium, they actually increase the profitability of coal and
uranium more
than PV solar.
In addition, a relatively small amount of
uranium can produce a relatively
large amount of energy, helping the overall energy cycle of an online nuclear plant to release no more carbon dioxide per kilowatt - hour
than solar power, which must account for the manufacturing of photovoltaic cells.
