This is a diagram of an advanced reactor designed to both produce electricity and hydrogen. The NRC presentation which discusses the design is available at http://www.nuclear.com/archive/2009/04/14/Next_Generation_Nuclear_Plant-NRC-20090414-ML091030059.pdf.

The state-run company said the PC method uses prefabricated sections made by two steel plates embedded with "studs" that are made at factories and shipped to the construction site. Once they are in place, concrete is poured into the space between the plates to form solid walls. "This method is safer, faster, reduces environmental pollution and can be used in the construction of industrial plants and other facilities," a KHNP spokesperson said. The official said the new method was roughly two years ahead of similar research being conducted abroad.
In the past, contractors relied solely on the reinforced concrete method to make specially designed walls at nuclear power plants that required steel reinforcement bars to be built in place, molds to be set up to outline walls, and the space created by the molds filled with cement.

Mr. Tucker just published a book titled Terrestrial Energy: How Nuclear Power Will Lead the Green Revolution and End America’s Energy Odyssey. His article title about closing Oyster Creek is not because he thinks shutdown is warranted, but because New Jersey would be so hurt by shutdown that the resultant howling and gnashing would be instructive the rest of the country.
