Submarines: Brazil Builds Its Own SSNs


July 15, 2007: 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.
