Release the Kraken: Energy Hubs and Simulation

a06_p09_kraken_med The transition at the U.S. Department of Energy from a business oriented secretary – Samuel Bodman, who also had been Director of M.I.T.'s School of Engineering Practice – to a research oriented secretary – Steven Chu, previously the director of the Berkeley National Laboratory – has, naturally enough, led to an increased stress on research. While DOE always engages in research, Chu’s touting of energy hubs as engines of new ideas, as mini-Manhattan Projects, has been consistent.

He has, however, had some trouble with Congress over them, with the House approving only one of eight proposed and the Senate going for three. It may be that Chu hasn’t sold them aggressively enough, it may be general budget concerns in Congress, but three is the number for now. Two relate to renewable energy sources, the third to nuclear energy. So we were interested to run into this:

The University of Michigan has been named part of a national hub for boosting U.S. nuclear energy research and development.
The Ann Arbor university said nine engineering faculty members will lead its part of the Nuclear Energy Modeling and Simulation Energy Innovation Hub. The hub which includes other academic, industrial and government institutions [sic]. It's led by Oak Ridge National Laboratory in Tennessee.

Well, congratulation to the University but it’s not much. Let’s see if someone has more on this:

Core members of CASL are Oak Ridge, Los Alamos, Idaho and Sandia national laboratories; the Massachusetts Institute of Technology, the University of Michigan, and North Carolina State University; and the Electric Power Research Institute, the Tennessee Valley Authority, and the Westinghouse Electric Co. A dozen other universities, companies and organizations in this country and in Europe also are contributing to the program.

Better. CASL is The Consortium for Advanced Simulation of Light Water Reactors. And here’s a description of what this group is aiming to do:

The consortium’s goal is to create a virtual reactor that can be used to improve the performance and safety of existing reactors and to help design the next generation.

And why it’s important:

“Before you go testing a new reactor design, you need to have that design validated against existing reactors,” said Douglas Kothe, director of science at Oak Ridge’s National Center for Computational Sciences and director of the consortium. “What we are building is a modern, high-fidelity simulation tool, rigorously validated, to push the state of the art.”

Here’s DOE’s page about this project and a look at its future:

After five years, the Hub is intended to produce a multi-physics computational environment that can be used by a wide range of practitioners to conduct predictive calculations of the performance of reactors in the future for both normal and off-normal conditions.

In other words, something of value to a wider cohort than only simulation specialists:

The mission focus of the NE [nuclear energy] Hub is to apply existing modeling and simulation capabilities to create a user environment that allows engineers to create a simulation of a currently operating reactor that will act as a "virtual model" of that reactor.

This is a tremendously exciting and (surprisingly) practical project. We’ll have to see if the consortium really makes this user-friendly (well, to those users to whom it applies, anyway); if so, its application would be a boon for the industry.

This is an area where supercomputers have a place and the project will be using three computing behemoths – two Crays and one IBM – to provide the horsepower. We were amused to see that one of Oak Ridge’s Crays is named Kraken, given the number of times we heard Liam Neeson bellow, “Release the kraken” in previews for Clash of the Titans this spring. Release the kraken indeed.

Kraken itself.

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…

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…

Nuclear Is a Long-Term Investment for Ohio that Will Pay Big

With 50 different state legislative calendars, more than half of them adjourn by June, and those still in session throughout the year usually take a recess in the summer. So springtime is prime time for state legislative activity. In the next few weeks, legislatures are hosting hearings and calling for votes on bills that have been battered back and forth in the capital halls.

On Tuesday, The Ohio Public Utilities Committee hosted its third round of hearings on the Zero Emissions Nuclear Resources Program, House Bill 178, and NEI’s Maria Korsnick testified before a jam-packed room of legislators.


Washingtonians parachuting into state debates can be a tricky platform, but in this case, Maria’s remarks provided national perspective that put the Ohio conundrum into context. At the heart of this debate is the impact nuclear plants have on local jobs and the local economy, and that nuclear assets should be viewed as “long-term investments” for the state. Of course, clean air and electrons …
