The What Where When of Used Nuclear Fuel

fig43 Ever since Yucca Mountain succumbed – well, almost succumbed – to the Obama administration’s uncertainties about it, the question of  used nuclear fuel has been a bit of a question mark.

Hmmm, maybe that’s misleading. The fuel currently rests in pools or in dry storage casks, mostly at the plants. It’s been doing that for years without issue. A central repository would be ideal, as overseeing one of anything is per se better than overseeing multiple instances of essentially the same thing. (We’re simplifying, of course – radiant matter is handled differently across industries – but Yucca was It for commercial nuclear plants.)

It’s not quite a case of keeping the Brain People of Antares safe when they visit an empty earth a million years from now – they’re tough hombres and can take care of themselves quite nicely, plus they sprinkle their morning cereal with plutonium – but a logistical issue.

And it’ll get taken up again at some point, whether the answer is Yucca Mountain or some other locale. The law more or less requires it – the U.S. has contracts to move the material to a central repository.

But for now, what?

The U.S. Nuclear Regulatory Commission is proposing to double the period that nuclear power plants can store spent fuel on site to 40 years, as plans to build a permanent federal repository stall.

The rule would formalize a site-by-site exemption the commission has used when nuclear plants, including those owned by Dominion Resources Inc. and Progress Energy Inc., applied to renew waste storage licenses for longer than 20 years.

Which means the NRC is codifying what it’s already doing. It’s not ideal but it is realistic. In terms of plant and public safety, it’s non-controversial. (And there are some non-plant sites that store casks, too.)

If you want to read more about dry cask storage, which is an exceedingly well developed piece of kit, go here.

We did frown at this a bit:

Energy Secretary Steven Chu has called for a panel to recommend a way forward for the U.S. nuclear waste, looking at potential waste sites and reprocessing the fuel to reduce its radioactivity and volume.

We real-l-l-l-y want to see the kick off of this commission. While most such commissions are, at best, efforts to kick-the-can of a difficult issue down the road a piece, this one has real potential to to remove uncertainties and set a course for the future. And we’ll be exceptionally frustrated if it doesn’t get rolling until the Brain People of Antares can be members of it.

But that’s just us and our impatience: we do expect energy issues, including this one, to start popping again when the climate change bill returns to the fore.

A dry cask. Bigger than you’d think, isn’t it?

There already is an NRC licensed facility for 40,000 tons of spent fuel for 40 years. This would provide an alternative to on site storage or on sites where the power plant is decommissioned. See http://web.archive.org/web/20071227225023/http:/www.privatefuelstorage.com/ . Unfortunately, congress blocked it, so the only thing that actually exists is the license.

Interesting Paul. NRC's letter issuing the licence is here. Do you have a reference to the Congressional action to block it?

I'm amused by the use of an apparently naked female silhouette for scale on the cask picture (perhaps that was the idea). At her distance from such a cask, what would the levels of radiation be if the cask was loaded with typical 10-year-old spent fuel?

Skull Valley Band of Goshute Indians and Private Fuel Storage Seek Reversal of Interior Department Rulings

On July 17, 2007, PFS and the Skull Valley Band of Goshute Indians filed a complaint, in U.S. District Court in Salt Lake City, against officials of the U.S. Department of Interior for their decisions of September 2006 disapproving the PFS-Goshute lease and the use of public lands for an Intermodal Transfer Facility.

The Claim asks the Court to vacate the DOI decisions and require DOI to reconsider both issues on a strict timetable, this time adhering to the Department's own regulations as well as other federal laws and policies.


Congress could allow it just by passing a bill. Previously, Private Fuel Storage tried to build 30 miles of railroad, but congress declared the area a wilderness to prevent this. Sorry, don't have a reference for that handy. In any case, it took 8 years to license the site, and any new site would have to start an application from scratch.

Knowing What You’ve Got Before It’s Gone in Nuclear Energy

The following is a guest post from Matt Wald, senior director of policy analysis and strategic planning at NEI. Follow Matt on Twitter at @MattLWald.

Nuclear energy is by far the largest source of carbon prevention in the United States, but this is a rough time to be in the business of selling electricity due to cheap natural gas and a flood of subsidized renewable energy. Some nuclear plants have closed prematurely, and others likely will follow.
In recent weeks, Exelon and the Omaha Public Power District said that they might close the Clinton, Quad Cities and Fort Calhoun nuclear reactors. As Joni Mitchell’s famous song says, “Don’t it always seem to go that you don’t what you’ve got ‘til it’s gone.”
More than 100 energy and policy experts will gather in a U.S. Senate meeting room on May 19 to talk about how to improve the viability of existing nuclear plants. The event will be webcast, and a link will be available here.
Unlike other energy sources, nuclear power plants get no specia…

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…
