Winter Fury, Meet Nuclear Reliability

Unless you live in Siberia, you probably don’t care much about when it snows there. But some meteorologists care, because it may act as a bellwether for how things will go in the rest of the northern hemisphere. And things are looking a little rough this season:

About 14.1 million square kilometers of snow blanketed Siberia at the end of October, the second most in records going back to 1967, according to Rutgers University’s Global Snow Lab.

Global Snow Lab? And their logo isn’t a snow globe!? Anyway, what does the snow in Siberia mean for us?

Taken together they signal greater chances for frigid air to spill out of the Arctic into more temperate regions of North America, Europe and Asia, said Judah Cohen, director of seasonal forecasting at Atmospheric and Environmental Research in Lexington, Massachusetts, who developed the theory linking Siberian snow with winter weather.

There’s been a tendency lately to pay more attention to the weather, likely because the polar vortex last year proved to be such a boon for the media. The weather is now click bait. Cohen’s ideas about Siberian snow and its impact are interesting – and maybe genuinely predictive – but a lot of people find themselves content with the Farmers Almanac (which isn’t too far off from Cohen, come to think of it).

What does this have to do with nuclear energy? Everything.

But peak electricity prices could exceed 100¢/kWh like they did last year during the polar vortex (Forbes).

Not sure why New Englanders are so surprised. It was their choice to throw all-in for natural gas and renewables in a land of harsh winters. But they’ve refused to build new gas pipelines. And they’re shutting a nuclear plant that has 20 years of cheap reliable cold-resistant energy left on it.

And natural gas froze in the pipes during the vortex last year, with nuclear energy picking up the slack. Uranium might or might not freeze if it were stacked in piles like coal, but it’s not in piles – it’s in the reactor, making heat.

This reliability was literally a life saver last year. And it still gets notices. From the New York Times, today:

To people in the American nuclear industry, reactors do not get the respect they deserve for being both virtually emissions-free and a source of around-the-clock electricity for the grid. Experts point to the spell of extreme cold weather across much of the country last January, when nuclear plants kept working while many gas and coal plants had to shut down as the cold affected equipment and fuel supplies.

NEI did a package on nuclear energy’s reliability a bit ago, but it’s worth taking another look at as we approach the upcoming, um, Siberian winter. We of course hope for sunshine and beach temperatures – as who doesn’t – but it’s nice to know that when the weather doesn’t cooperate, nuclear energy does.

Then there is Bilibino NPS in Russia, notable as the northern-most operating NPP in the world. Also notable for having a dry cooling system to condense the steam.

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

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 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 …
