You're mostly right, with a couple of exceptions: 1. China is working on a mass-producible pebble bed reactor, the 100 MWe HTR-PM. The first pair of them are under construction, and are scheduled to start commercial operation in 2015. 2. It's possible to run existing pressurized light water reactors on a fuel mix consisting mostly of thorium. This has nothing to do with the capital costs of construction, but if uranium ever gets a lot more expensive, it could be a very useful option.
