TOWNHALL DEBATE: ARE CONVENTIONAL REACTORS AND SMALL MODULAR REACTORS RIVALS?

Friday, October 22nd, 2010

“Disruptive technology” was a phrase that kept coming up at Infocast’s Small Modular Reactors Conference in Washington, DC this week.

The term was coined by Harvard Business School professor Clayton M. Christensen in his 1997 book, The Innovator’s Dilemma, in which he showed that even the innovators of new technology can hurt themselves by introducing it if they are already well established in the old technology. Therefore, new technologies are usually developed by newcomers in the field.
 
The description would seem to fit the U.S. Nuclear Renaissance at this moment. The proposals for small reactors are coming mostly from upstart companies such as NuScale, Hyperion, Advanced Reactor Concepts, Radix, TerraPower and a reincarnated Babcock & Wilcox, which has dropped out of the full-scale field. Meanwhile, the established companies – AREVA, Westinghouse, General Electric and General Atomics – are “keeping up with the Jones” at best.
 
But there is a new element to the equation – the Nuclear Regulatory Commission. The limiting factor in any reactor development, old or new, in this country, at least, will be getting licensed by the NRC. The Commission’s time – which is subject to Congressional appropriations and dedicated to safety issues first – can be finite even at its pass-through rate to users of $260 hour.  And any effort spent on SMRs could logically be subtracted from time spent reviewing larger reactors. Thus, when Hyperion sat down with NRC officials earlier this month, the company was only adding to the Commission’s overload.

There won’t be any Apples or Netscapes upsetting the established order in the nuclear industry. Ultimately, along with securing customers, everything will depend on successfully navigating uncertain NRC regulatory regime waters over a five-year period at a minimum. In this department, established technologies will have an advantage, since, even more than major corporations, bureaucracies have trouble adjusting to innovation.
 
“I believe if the nuclear industry is going to succeed, we have to succeed as a whole,” said Gary Barbour, senior advisor for regulatory affairs at NuScale Power at the conference. In winning public acceptance, this is obviously true. But is there also a sibling rivalry?  Are big and small reactors partners or rivals?  Are small reactors and large reactors an either/or proposition for the industry or can the industry and the NRC multi-task?  Are small reactors an untimely distraction at a time when the Renaissance should be focused on consummating a spate of new large reactor deployments over this decade?

 

 

DEBATE OF THE WEEK: CAN THE U.S. COMPETE GLOBALLY ON THE SMR PLAYING FIELD?

Friday, July 16th, 2010

By William Tucker
Last April, Secretary of Energy Steven Chu sounded an optimistic note in an op-ed for The Wall Street Journal.  While the U.S. is challenged in the manufacturing of full-sized reactors market, he said, an opportunity was opening in small modular reactors in the range of 75 to 150 megawatts.

“Small modular reactors  . . have compact designs and could be made in factories and transported to sites by truck or rail. SMRs would be ready to "plug and play" upon arrival. . . . Their small size makes them suitable to small electric grids so they are a good option for locations that cannot accommodate large-scale plants . . .. If we can develop this technology in the U.S. and build these reactors with American workers, we will have a key competitive edge.”

The article caused a flurry of excitement in the nuclear industry where a bevy of companies — ranging from established competitors Babcock & Wilcox (B&W), GE, Westinghouse and General Atomics to emerging companies such as NuScale and Hyperion — were advancing new SMR initiatives.  The government was becoming a proponent for serious nuclear energy innovation.  Legislation was introduced in the Congress to spur development and $40 million proposed in the President’s FY2011 budget request. The U.S. Nuclear Regulatory Commission followed suit projecting approval of a design as early as 2017.  TVA announced its interest in SMR deployment. Experienced manufacturers such as Electric Boat and Northrop Grumman were at the ready. And this week, Bechtel jumped on board the SMR express.  

Notwithstanding the U.S. awakening in this arena, the rest of the world is moving ahead rapidly.  Toshiba has a 10-MW “4S” (Super Safe, Small and Simple) reactor it offering to give to Galena, an isolated Alaskan village, as a demonstration.  Russia has a modular reactor it is floating into Siberian villages on barges.  Two weeks ago the Koreans announced they are entering the field as well.

Ironically we’ve been building “small modular reactors” for 50 years.  They go on U.S. Navy nuclear submarines. The reason B&W has a technical domain in SMRs — and related U.S. manufacturers have expertise in this market — is because it already has a business supplying them to the Navy.

But at the current pace of NRC design and licensing approval, it may be the better part of a decade before anybody can get something out the door in the U.S.  By that time, agile Japanese and Korean competitors may have moved out front in the global market.

So is it realistic to think America can compete in this field international?  And if not, what can we do about it?
