DOE Awards NuScale Second Small Reactor Grant

Let’s see what’s behind the headline, via the AP:

The U.S. Department of Energy said Thursday that it has awarded an Oregon company a grant to help it design and obtain federal approval for a kind of nuclear power plant - small modular units that can be built in a factory and shipped to installation sites.

That Oregon company is NuScale, a startup company with strong ties to Oregon State University The first DOE award went to the mPower small modular reactor design being developed by long-established Babcock & Wilcox, a company that has been building small reactors for the U.S. Navy for decades. NuScale’s technology approach is unique and allows capacity additions in 45 megawatt increments. In addition, its safety features directly address the lessons learned from the Fukushima Daiichi accident. It’s a pressurized water reactor – as is mPower – with a lot of new ideas regarding safety.

[NuScale offers] a smaller, scalable version of pressurized water reactor technology with natural safety features which enable it to safely shut down and self-cool, with no operator action, no AC or DC power, and no external water. Each NuScale Power Module is 45 MW and has a fully integrated, factory-built containment and reactor pressure vessel.

NuScale lists its attributes:

The ability to safely shut down and self-cool, indefinitely, with no operator action, AC or DC power, and no additional water, with NuScale's Triple Crown for nuclear plant safety™ .
Seven barriers, between the nuclear fuel and the local community and environment, as compared to three for commercial plants currently in construction and operation.
A complete containment and reactor vessel module that can be shipped in segments, by rail, truck, or barge, for quick installation at the plant site.
Below grade operating bays for the NuScale Power Modules that are enclosed in an aircraft-impact-resistant seismic Category 1 reactor building.
Natural circulation, coolant flow residual heat removal and emergency core cooling systems are powered by natural forces, gravity.
A common pool that provides seismic dampening and radiation shielding for the NuScale Power Module.
A 60-year plant life
A projected capacity factor of >95%

Much of this describes the potential benefits of small reactors in general. But some of it, especially its approach to safety, leverages a patent portfolio NuScale has been building. I asked Paul Genoa, NEI’s senior director for policy development, about this:
“Just to be clear,” Genoa said, “all U.S. nuclear facilities exceed the stringent safety regulations of the Nuclear Regulatory Commission. However, just like the new Westinghouse AP-1000 plants under construction in Georgia and South Carolina, these new small reactor designs being supported by DOE are increasingly using innovative and elegant approaches to ensuring that safety.”
So there you go.
NEI offers a very good description of the implications of the DOE award:

DOE’s selection criteria focused on reactor technologies that have unique and innovative safety features to mitigate the consequences of severe natural events similar to those at Japan’s Fukushima Daiichi. NuScale’s press statement noted that its design’s “unique and proprietary break-through technology” using natural forces of gravity, convection and conduction will allow “safe and simpler operations and safe shutdown.”

And why this is different from the B&W award:

By contrast, DOE’s first solicitation focused on small reactor designs similar to certified large reactors that had the potential to be brought quickly to design certification and licensing. Late last year DOE selected a team consisting of Babcock & Wilcox, Bechtel International and Tennessee Valley Authority to deploy B&W’s 180-megawatt mPower small reactor design by 2022.

You’ll notice the team aspect of the mPower project. That’s true of NuScale, too: it is working with Rolls-Royce (yes, the car people, but they also produce small reactors for the British Navy-see the link), Fluor and Energy Northwest.
More from the AP, with some key dates moving forward:

The company hopes to have the design certified by 2019 and the first commercially operational project working by 2023 at the Idaho National Laboratory in Idaho Falls, Idaho, [NuScale Chief Commercial Officer Michael] McGough said.

This is spectacular news. We’ve been hearing about small reactors for years. Now, here they are.

Fluor Invests in NuScale

You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap...

Wednesday Update

From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...
