In Small Packages

udall The plausibility of using small nuclear reactors in situations where a full-scale reactor might be seen as overkill is an idea pushed, as you would imagine, by vendors with such reactors in their portfolios. In fact, a group of those vendors travelled around Washington during the early fall months scaring up as much interest in their wares to anyone who wanted to listen. Not just think tanks, but the NRC has hosted a presentation on small units.

NRC Chairman Gregory Jaczko told the NRC forum on small reactors in mid-October that his agency needs to ensure it has adequate resources to plan for detailed review of small and medium reactors. Among the issues needing resolution is focusing on specific technical designs.

“We need to hear from the industry about the demand for these reactors, and the industry’s development and deployment priorities,” Jaczko said.

Rod Adams has a terrific discussion of the NRC forum up at Atomic Insights.

Jaczko sounds measured but open, about what one would expect. It’s not exactly kick the can, but the can still ended up in the offices of Sen. Mark Udall (D-Col.) who decided to move the conversation forward a bit. He’s submitted an amendment to the Energy Act of 2005 to allocate $250 million to the Department of Energy to investigate ways to lower the cost of building new reactors.

Now, the small reactors are not the meat of the bill. Here’s how he describes its purpose:

To amend the Energy Policy Act of 2005 to require the Secretary of Energy to carry out a research and development and demonstration program to reduce manufacturing and construction costs relating to nuclear reactors, and for other purposes.

And here’s what he wants to be researched:

(A) modular and small-scale reactors

(B) balance-of-plant issues [that is, the elements of electricity generation not including nuclear reactors – things like turbines];

(C) cost-efficient manufacturing and construction;

(D) licensing issues; and

(E) enhanced proliferation controls.

So a bundle of thing, but this is the first mention of small reactors we’ve seen in legislation to date.


Interestingly, stories we’ve seen about this and the speech Udall gave on the floor of the Senate introducing it all fasten on the small reactors, though he didn’t mention them at all in his speech.

According to a report in the examiner, Colorado's senior U.S. senator has proposed a bill that would give the federal government authority to research whether small-scale, modular nuclear reactors are a feasible contributor to the nation's energy supply.

That’s from Nuclear Street. Our friend Dan Yurman over at Idaho Samizdat also focused on it:

Colorado Senator Mark Udall, has introduced a bill to authorize federal R&D for small, modular reactors. Udall said in a speech on the Senate floor he believes nuclear energy is an important part of the nation's response to global warming.

Here’s video of his speech if you want to take a listen.


It seems churlish to talk of small reactors and not provide a way for you to learn about them. So visit NuScale Power, Babcock & Wilcox, even the still-incubating TerraPower. That’ll get you started.

Sen. Mark Udall. We suspect every western politician has photos like this.

Making Clouds for a Living

Donell Banks works at Southern Nuclear’s Plant Vogtle units 3 and 4 as a shift supervisor in Operations, but is in the process of transitioning to his newly appointed role as the daily work controls manager. He has been in the nuclear energy industry for about 11 years.

I love what I do because I have the unique opportunity to help shape the direction and influence the culture for the future of nuclear power in the United States. Every single day presents a new challenge, but I wouldn't have it any other way. As a shift supervisor, I was primarily responsible for managing the development of procedures and programs to support operation of the first new nuclear units in the United States in more than 30 years. As the daily work controls manager, I will be responsible for oversight of the execution and scheduling of daily work to ensure organizational readiness to operate the new units.

I envision a nuclear energy industry that leverages the technology of today to improve efficiency…

Why America Needs the MOX Facility

If Isaiah had been a nuclear engineer, he’d have loved this project. And the Trump Administration should too, despite the proposal to eliminate it in the FY 2018 budget.

The project is a massive factory near Aiken, S.C., that will take plutonium from the government’s arsenal and turn it into fuel for civilian power reactors. The plutonium, made by the United States during the Cold War in a competition with the Soviet Union, is now surplus, and the United States and the Russian Federation jointly agreed to reduce their stocks, to reduce the chance of its use in weapons. Over two thousand construction workers, technicians and engineers are at work to enable the transformation.

Carrying Isaiah’s “swords into plowshares” vision into the nuclear field did not originate with plutonium. In 1993, the United States and Russia began a 20-year program to take weapons-grade uranium out of the Russian inventory, dilute it to levels appropriate for civilian power plants, and then use it to produce…

Nuclear: Energy for All Political Seasons

The electoral college will soon confirm a surprise election result, Donald Trump. However, in the electricity world, there are fewer surprises – physics and economics will continue to apply, and Republicans and Democrats are going to find a lot to like about nuclear energy over the next four years.

In a Trump administration, the carbon conversation is going to be less prominent. But the nuclear value proposition is still there. We bring steady jobs to rural areas, including in the Rust Belt, which put Donald Trump in office. Nuclear plants keep the surrounding communities vibrant.

We hold down electricity costs for the whole economy. We provide energy diversity, reducing the risk of disruption. We are a critical part of America’s industrial infrastructure, and the importance of infrastructure is something that President-Elect Trump has stressed.

One of our infrastructure challenges is natural gas pipelines, which have gotten more congested as extremely low gas prices have pulled m…
