Current-generation U.S. nuclear submarines are likely to cost around $2 billion each to construct (after including R&D costs).

billions of dollars
Nearly what it cost to build them.
7,636 tons
The current-generation U.S.S. Virginia nuclear attack submarines cost between 1.8 and 2 billion dollars each, including the amortized development costs for designing the class (i.e. it costs about 1.4 billion or so to actually build the sub, but there were several billion in startup, R&D, and design costs for the class, which adds about .5 billion to each sub). A typical non-nuclear attack submarine (such as the German Type 212) costs around $500 million, including the amortized development costs. Note that the typical non-nuclear attack submarine is usually about half the size (and a quarter of the displacement) of a nuclear attack sub.
Sorry, but that information is classified.
Nuclear plants are expensive to build but cheaper to run than fossil fuelled plants. Overall the cost delivered to consumers is much the same

The cost is approximately 98.9 Billion U.S.D. A single nuclear powerplant such as fukushima cost around 400 million to build.
Construction of the infrastructure to build them cost $2,000,000,000 but the incremental cost per bomb was much less, I doubt they cost a million a piece and the cost would have dropped with increased production.
The generating cost is much the same overall as coal, the fuel cost is lower but the plants are more expensive to build. Most nuclear plants run on base load because the fuel cost is lower.
