plans on the development of a new type of nuclear reactor. Based on so-called pebble bed technology currently being tested in South Africa, the new reactors will cost less to build, Exelon hopes. And because the new type of reactor is mass-produced, it could sail through the approval process more quickly."It would be built primarily at factory, and then shipped out and installed at a site, at less expense," says David Knox, a spokesman for Exelon's energy unit. "It would be quicker and cheaper in construction, and it should make it much simpler to license."According to Knox, Exelon's huge nuclear plant in Byron, Ill., cost $4.5 billion to construct.

A plant consisting of three of the new units would generate about 15 percent as
