Energy Outlook on the Gore Testimony

As we noted earlier this week, during his testimony on Capitol Hill this week, former Vice President Al Gore went to pains to say he wasn't reflexively anti-nuclear, though he added that he believed a combination of distributed generation and "smart-grid" technology could obviate the need to build new baseload generating capacity.
Mr. [Gore] worked hard to avoid sounding rigidly anti-nuclear, focusing instead on concerns about waste storage--he opposes the Yucca Mountain waste facility--and the very large capital costs involved in building new nuclear plants. Yet despite these issues, we are likely to see the first new nuclear plant in this country in two decades get its permits within a few years. The cloud of uncertainly that the recent TXU deal has cast over new coal-fired power plants will inevitably improve the prospects for new nukes.

To refine a statistic tossed out by one Senator, in 2005 nuclear power contributed 68% of all the low-carbon electricity generated in the US. As we contemplate a cap on carbon emissions and a carbon tax or an emissions trading system--or both, as Mr. Gore advocated Wednesday--the market value of all those green electrons from wind, solar, hydropower and nuclear will go up significantly. I doubt we can rely exclusively on wind and solar energy to provide all the green electricity we'll need, and efficiency won't eliminate the role of central power plants. I'd be very surprised if the greener world we need to create didn't also feature a bigger contribution from nuclear power.
I'm sure Mr. Gore would be surprised too.

Al Gore deserves credit for taking a lot of effort, for a lay person, to study the science behind global warming. I think that he is right that the current evidence is sufficient to support a call to action to reduce our carbon emissions. But now Mr. Gore needs to study the science behind geologic isolation of nuclear wastes, and to reconsider his opposition to the Yucca Mountain repository. Currently for climate change, our predictions for the next 100 years have substantial uncertainty. For geologic isolation of nuclear wastes, we can make scientifically sound predictions for probable behavior over the next one million years. And what does the science tell us? For geologic isolation of nuclear wastes, the worst long term consequence would be contamination of small amounts of ground water tens of thousands of years in the future. If, in the future, our great-great-great-grandchildren were to decide that they have a better approach to manage the materials we would put into Yucca Mountain, they can take them out with little difficultly. If only the same were true for carbon dioxide. Mr. Gore may not want to upset Mr. Reid, but the truth is that the United States needs a safe, secure place to put the residual wastes that come from using nuclear energy, and all of the current evidence says that Yucca Mountain is just fine for this purpose. Let's move forward and get a license application docketed for Yucca Mountain.

Well, the opposition to Yucca is pretty obvious NIMBYism. That said, we'd be a lot better off if we ended the reprocessing ban. We'd be able to stretch the nuclear fuel supply that much longer and reduce both the volume and lifespan of the waste.

Vice President Gore needs to read about Oklo, if he is actually worried about the capability of Yucca Mountain.

Nuclear is not a zero CO2 emission power source. That's a no-brainer! There are twenty steps to the fuel and power production cycle for nuclear energy, compared with seven for fossil fuel. Here is a summary of these steps.
Seven life-cycle steps of fossil fuels:
1 mine, powered by oil
2 transport to plant, powered by oil and electricity, mostly coal
3 combustion, powered by the fossil fuel from the plant
4 scrub emissions, powered by fossil plant energy
5 dispose of toxins, powered mostly by oil
6 build plant, powered by oil
7 dismantle plant, powered by oil
Twenty lifecycle steps to the nuclear fuel cycle
1 mining 0.3% U3O8 ore, powered by oil
2 milling to 100% U3O8, powered by oil
3 conversion to UF6, including several sub-steps of chemical processing, powered by oil mostly
4 enrichment: take the milled uranium which is .7% U235 and 99.3% and U238 to get the U235 up to 3.2%, powered by electricity, mostly coal
5 reconversion to U308 with 3.2% of that being U235, powered by oil and electricity which is mostly from coal
6 fabrication, powered by oil to mine the zircaloy fuel cladding
7 using the fuel in the reactor, powered by the nuclear fuel itself
8 taking out the spent fuel and putting it into interim storage in spent fuel ponds, powered by energy from the nuclear plant
9 isolating and guarding waste of the long-term storage phase of spent fuel (perhaps two steps), powered by energy from the nuclear plant and off-site electricity mostly from coal and from oil in the creation of the matrix, I am guessing on this one, since the technology is evolving
10 isolating and guarding waste of uranium mining tailings, powered by oil
11 isolating and guarding waste of mill tailings, powered by oil
12 isolating and guarding waste of conversion machinery contamination, powered by oil
13 isolating and guarding waste of enrichment machinery contamination, powered by oil
14 isolating waste of re-conversion machinery contamination and the associated depleted uranium, powered by oil
15 isolating and guarding waste from the fabrication process, powered by oil
16 retrieval of stolen waste
17 concurrently with the waste steps, setting up coordination of the nuclear waste plan, including policing, maintenance and repair of containment, criminal investigation and prosecution, cleanup from terrorist or accidental contamination (these systems do have their energy inputs, though difficult to quantify), powered by oil for transportation and construction of structures and electricity

-- There are the additional 3 steps of the nuclear plant cycle:
18 construction of the plant, powered by oil
19 operation of the plant, powered by the nuclear fuel
20 dismantlement of the plant and isolation from the environment, powered by oil

Of course, there is some speculation about the fuel source for some of these steps, due to many of them being performed in the future.
However, it is not reasonable to say that nuclear power does not emit CO2.

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 …
