Cold, Sure, but Nuclear a Reliable Tonic

You’ve probably heard enough from us about last year’s polar vortex (brutal) and the nuclear performance during it (great), so we’ll keep this brief – or at least let others do do the talking. Here’s TVA:
The Tennessee Valley Authority broke an all-time February power demand record Thursday morning with an estimated 32,109 megawatts at 7 a.m. EST, when the average temperature across the region hovered at 7 degrees.
In its 82-year history, this is TVA’s highest ever demand for the month of February. The previous record was 31,045 megawatts set on Feb. 5, 2009, when the Valley-wide temperature was 15 degrees. TVA’s all-time power demand record is 33,482 megawatts on Aug. 16, 2007.
All of TVA’s reactors operated at 100 percent over the last couple of days. The current situation doesn’t have the same quality of the polar vortex – that was fast and cruel while what the country has experienced over the last couple of weeks has been weather writ large – not slow and kind, to be sure, but easier to anticipate its impacts.

To an extent, anyway. Coming from the south, I can attest that that region of the country is never ready for cold weather much less snow and ice. So TVA’s performance is especially noteworthy.
What about the perpetually shivery northeast?
This is corroborated by nuclear’s excellent performance this winter.  On January 8th, in the midst of frigid arctic temperatures in the Northern U.S., nuclear facilities provided 27 percent of the early afternoon electricity demand for the PJM Interconnection wholesale electricity market spanning the mid-Atlantic region and much of the Midwest.  All but one of the 33 plants in this region operated at full capacity.  In the New York and New England independent service operator (ISO) markets, nuclear operated at a 100 percent capacity factor during this time.  No other energy source even comes close to this level of reliability.
As always, we’ll let other energy generators do their own humblebrag thing – I’m sure there are good stories to tell there, too.
Despite nuclear energy’s incredible resilience during extreme weather and these many benefits, some nuclear plants across the country are in danger of shutting down, or already have shut down due to a confluence of economic factors that are working against them.  These premature closures have a variety of negative impacts for the communities and regions they serve.
This is really the point. We could take this from the diversity, reliability or emissions perspectives, but the idea is the same: without nuclear energy, winter is a little colder and a little more polluted. It needs to be valued for what it offers.

What about Pilgrim shutting down in storm Juno and then shutting down for Neptune?

New Home for Our Blog: Join Us on NEI.org

On February 27, NEI launched the new NEI.org. We overhauled the public site, framing all of our content around the National Nuclear Energy Strategy.

So, what's changed?

Our top priority was to put you, the user, first. Now you can quickly get the information you need. You'll enjoy visiting the site with its intuitive navigation, social media integration and compelling and shareable visuals. We've added a feature called Nuclear Now, which showcases the latest industry news and resources like fact sheets and reports. It's one of the first sections you'll see on our home page and it can be accessed anywhere throughout the site by clicking on the atom symbol in the top right corner of the page.
Most importantly for you, our loyal NEI Nuclear Notes readers, is that we've migrated the blog to the new site. Moving forward, all blog posts will be published in the News section, along with our press releases, Nuclear Energy Overview stories and more. Just look for the &qu…

Hurricane Harvey Couldn't Stop the South Texas Project

As Hurricane Harvey battered southeast Texas over the past week, the devastation and loss of life in its wake have kept our attention and been a cause of grief.

Through the tragedy, many stories of heroics and sacrifice have emerged. Among those who have sacrificed are nearly 250 workers who have been hunkered down at the South Texas Project (STP) nuclear plant in Matagorda County, Texas.

STP’s priorities were always the safety of their employees and the communities they serve. We are proud that STP continued to operate at full power throughout the storm. It is a true testament to the reliability and resiliency of not only the operators but of our industry.

The world is starting to notice what a feat it is to have maintained operations through the catastrophic event. Forbes’ Rod Adams did an excellent job describing the contribution of these men and women:

“STP storm crew members deserve to be proud of the work that they are doing. Their families should take comfort in the fact that…

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…
