Church and colleagues are also adapting the approach for
use with other useful bacteria, including Shewanella, which can convert toxic
metals such as
uranium into an insoluble form, and cyanobacteria which can extract energy from light
using photosynthesis.
Depleted
uranium metal can be
used as shielding, for example.
Rather than the pellets of
uranium oxide
used in other fast reactors and conventional reactors as fuel, GE would fabricate
metal alloy fuels, with the plutonium or
uranium mixed with zirconium
metal.
Uranium metal enriched with
Uranium - 235 is
used in heavy water reactors while light water reactors
use low enriched
Uranium.
All other sodium reactors
use oxide fuels, while PRISM
uses a
metal fuel, an alloy of zirconium,
uranium, and plutonium, and the fuel rods sit in a bath of liquid sodium at atmospheric pressure.
The data they provide can be
used in other studies examining the oxidation state of
uranium and other
metal compounds.
Unlike the current generation of light - water nuclear reactors, PRISM
uses metallic fuel, such as an alloy of zirconium,
uranium, and plutonium, and PRISM's fuel rods sit in a bath of a liquid
metal — sodium — at atmospheric pressure, which ensures that the transfer of heat from the
metal fuel to the liquid sodium coolant is extremely efficient.
This radioactive
metal is sometimes
used in the production of nuclear weapons as a substitute for depleted
Uranium.

Heavy
metals and toxic chemicals like depleted
uranium and Agent Orange were
used during these tests, with the result that residents of the island report the highest cancer rates in the Caribbean.
