FuturePundit Asks a Question About Nuclear Energy

Randall Parker, the brains behind FuturePundit, has been reading an EPRI study about the prospect of the electric industry being able to constrain carbon emissions going forward, and asks a provocative question:
The study assumes only a two thirds increase in nuclear power.


But imagine instead that we no longer built new coal or natural gas burning electric plants and all new electric plants used energy sources that generate no carbon dioxide. Coal burning technology isn't ready for full carbon sequestration. So go with nuclear and wind instead.

Most drastically, we could halt all carbon dioxide emissions from electric generation (cutting out a third of US CO2 emissions) by switching to only non-fossil fuels for electric power generation. For example, in the United States we could switch to nuclear where we now use coal and natural gas. In 2005 nuclear power accounted for 19.3% of total electric power generated. The United States had 104 nuclear reactors operating in 2005 with a total capacity of 97 gigawatts (almost 1 gigawatt per plant). So as a rough first approximation if we built 400 nuclear power plants or 4 times as much as we already have we could shut down all the fossil-fuels burning plants. Though that would not provide enough electric power during the peak afternoon demand periods.

So here's my question for knowledgeable readers: What percentage of electric power is used for baseline demand and what percentage is used for above baseline usage? Would we have to build 6, 7, or even 8 times as many nuclear plants as we have now in order to eliminate all use of fossil fuels to generate electricity?
I've already sent a link to Randall's post to the interested parties here at NEI, though we're all scattered around the Washington area for the President's Day holiday. Then again, there's no reason why our readers can't participate. Drop by and be sure to comment where appropriate.

It looks like my buddy Gerry Wolfe has posted the nearly-identical text to FuturePundit that he's posted on dozens of other sites, such as:

Wolfe seems to be going around putting his CSP pitch up anywhere that anyone mentions nuclear power as a possible way forward to combat global warming. Someone should call him on it. He could at least just post a link instead of copying the same drivel over and over. And he should admit he's an anti-nuclear activist.

Yeah, but after you've seen his spiel a half dozen times (it doesn't take long), you tend to ignore it.

There is no point in calling him on it. He doesn't stick around to read the other comments.

The best that you can do is to point out to the other readers (and perhaps the moderators) that his drivel is spam.

He actually tracks where the spam goes at a dedicated page on the TREC-UK website, but there's no associated discussion page that I can see.
Brian Mays said…
Wow! A spamlog! Now that's dedication.
Regarding the post itself, I've had a similar idea: no new fossil fuel power plants and a phaseout of coal-fired power plants, in exchange for no carbon tax and starting a national CTL initiative to prevent a collapse of the coal industry. All new power plants would have to use non-fossil-fuel processes, with no prejudice toward either renewables or nuclear (the exception being a cap on spent fuel production to encourage better use of uranium). The net result is independence from foreign oil, a positive impact on the economy, and a 30% reduction in carbon dioxide emissions. Longer-term, plug-in hybrids can then start backing out coal until the necessary advances in battery technology are made.

I am confident enough in the (currently rather feeble) business case for reactor technology that I think such a system would result in about 85% nuclear (meaning about 25% light water, 20% heavy water, and 40% LMFBR), but if wind/solar/magic wiffle dust is as good as certain unnamed parties think it is, it would have just as much of an opportunity to succeed if not more.

What do you think?

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 …

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.


The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.

What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

Why Nuclear Plant Closures Are a Crisis for Small Town USA

Nuclear plants occupy an unusual spot in the towns where they operate: integral but so much in the background that they may seem almost invisible. But when they close, it can be like the earth shifting underfoot., the Gannett newspaper that covers the Lower Hudson Valley in New York, took a look around at the experience of towns where reactors have closed, because the Indian Point reactors in Buchanan are scheduled to be shut down under an agreement with Gov. Mario Cuomo.

From sea to shining sea, it was dismal. It wasn’t just the plant employees who were hurt. The losses of hundreds of jobs, tens of millions of dollars in payrolls and millions in property taxes depressed whole towns and surrounding areas. For example:

Vernon, Vermont, home to Vermont Yankee for more than 40 years, had to cut its municipal budget in half. The town closed its police department and let the county take over; the youth sports teams lost their volunteer coaches, and Vernon Elementary School lost th…
