Various small steam engines are built and marketed throughout the USA and the world today. This includes engines producing several horsepower, typical for steamboats, etc. The last large US manufacturer of steam engines, Skinner Engine Company, went out of business about 1980, and the last large engine that they built powered a generator in a large central station power plant. This generator powered the exciter for the main turbine driven generator, and is in the vicinity of 1,000 - 2000 Horsepower.

It is estimated a new nuclear plant built today in the US would cost $10-12 billion for a 1500-1600 MW plant. Then once you have the plant built, one load of fuel bundles would cost approx. $150 to $200 million.
According to the US Dept of Energy, the last reactor built was the "River Bend" plant in Louisiana. Its construction began in March of 1977.
