more,» Trump tweeted.
Supporters of the deal argue that Iran is just months from creating weapons - grade
uranium at any of its 19,000 refining centrifuges, and that only the agreement can stave off such a development for a decade or
more.
Instead of running on solid
uranium — the industry's mainstay for
more than 50 years — it would rely on liquid fuel suffused with thorium, which is three times as abundant as
uranium.
Since neutrons traveling through heavy water split atoms
more efficiently, less
uranium should be needed to achieve a critical mass; that's the minimum amount of
uranium required to start a spontaneous chain reaction of atoms splitting in rapid succession.
This is important because slowly moving neutrons are
more efficient at splitting
uranium atoms than fast moving neutrons.
And the Americans chose to slow the neutrons emitted from their enriched
uranium with
more readily available graphite, rather than heavy water.
Every time an incoming neutron bombards one of the
uranium atoms, the atom splits in two, expelling energy and releasing
more neutrons, which in turn collide with other atoms and establish a chain reaction.
Then they'd run into other
uranium nuclei and induce a second round of fission reactions, emit even
more neutrons, and on and on.
And then there are the colored shells from Cueva de los Aviones, a sea cave in southern Spain, where Hoffmann's
uranium - thorium dating of a calcite crust covering the objects has just yielded an age of
more than 115,000 years.
Compared weight - by - weight,
uranium 235 delivers a million times
more energy than coal, which itself already represents chemical energy in a highly concentrated form.
The agency says the Hanford site in southeastern Washington, which manufactured
more than 20 million pieces of
uranium metal fuel for nine nuclear reactors near the Columbia River, is its biggest cleanup challenge.
Uranium 238 is much more common in nature than uranium 235 but does not fission well, so fuel manufacturers boost the uranium 235 content to a few percent, which is enough to maintain a continuous fission reaction and generate elect

What is
