Fight between Big Nuclear reactor makers and Small Nuclear makers coming out into the open?

Nuclear Options The Economist, print version, 28 Jan 17 “………Not one of the two technologies that were supposed to revolutionise the supply of nuclear energy—the European Pressurised Reactor, or EPR, and the AP1000 from America’s Westinghouse—has yet been installed, despite being conceived early this century. In Finland, France and China, all the EPRs under construction are years behind schedule. The main hope for salvaging their reputation—and the nuclear business of EDF, the French utility that owns the technology—is the Hinkley Point C project in Britain, which by now looks a lot like a Hail Mary pass.

Meanwhile, delays with the Westinghouse AP1000 have caused mayhem at Toshiba, its owner. The Japanese firm may announce write-downs in February of up to $6bn on its American nuclear business. As nuclear assets are probably unsellable, it is flogging parts of its core, microchip business instead……..

the business case for a new breed of small reactors below 300MW is improving. This month, Oregon-based NuScale Power became the first American firm to apply for certification of a small modular reactor (SMR) design with America’s nuclear regulators.

“Clearly the momentum seems to be shifting away from traditional suppliers,” says William Magwood, director-general of the OECD’s Nuclear Energy Agency……

The WNA also notes in a report this month a “revival” of interest in SMRs, partly because of rock-bottom sentiment toward large plants. Utilities are finding it tough to pay for big projects (Barakah, for instance costs a whopping $20bn), especially in deregulated power markets where prices have slumped because of an abundance of natural gas and renewable energy. Big investments can sink a firm’s credit rating and jack up its cost of capital.

It is less onerous to pay for an SMR, which means that even though they produce less energy, they can be cost-competitive with larger plants once they are being mass produced, says the WNA….
