Brazil is going to invest half a
billion dollars over the next eight years to develop a nuclear power plant for
submarines (SSNs, nuclear attack subs). Brazil has two nuclear power plants,
and the largest deposits of Uranium on the planet. The submarine power plant
would be designed to fit in an French or German submarine. Both of these
countries are now building subs with closed cycle power plants, which take up
nearly as much space as a nuclear power plant would. But the closed cycle
plants still use fossil fuel, and Brazil wants to reduce use of fossil fuels.
Thus Brazil would replace its current five conventional subs with four or five
nuclear ones. These boats would be used to patrol the sea lanes off Brazil's
long Atlantic coast.
