McCain Proposes Alternative to Yucca Mountain

John McCainSen. John McCain (R-AZ) has just completed delivering a major foreign policy speech on Nuclear Security at the University of Denver. (The full transcript is available here.) I found this quote especially interesting,
I would seek to establish an international repository for spent nuclear fuel that could collect and safely store materials overseas that might otherwise be reprocessed to acquire bomb-grade materials. It is even possible that such an international center could make it unnecessary to open the proposed spent nuclear fuel storage facility at Yucca Mountain in Nevada.
McCain's senior foreign policy advisers will be discussing the candidate's address in a conference call scheduled for later today. Over at Time's Swampland, Ana Marie Cox asks readers what they would ask if they were on the call. Imitation being the sincerest form of flattery and all, "What would you ask?"

First question I'd ask is where exactly on the globe would this international repository be?

Russia - the same place that supplies natural gas. So Russia gets to control all the world's spent fuel and much of its natural gas. Can you spell hegemony?

The notion of any sort of repository for used nuclear fuel, international or not, is absurdly wasteful.

Wasting all that used fuel, as opposed to any sort of recycling or reprocessing being implemented at all, is ridiculous.

Besides, the Russians aren't really thrilled with the idea of hosting a geological repository for other countries' spent fuel. They'd probably be happy to reprocess it, but the idea of being a "dump" for others' nuclear waste is not acceptable to the Russian public. As Pavel Podvig put it in his recent BAS column: "The Russian public may be sympathetic to using the spent fuel to recover plutonium and produce electricity--a grand vision promoted by the Russian nuclear industry--but it's not ready to accept the idea of permanently burying nuclear waste somewhere in Siberia."

So where do you plan to place all the vitrified HLW left over after reprocessing? Or the post-irradiation MOX fuel, which contains Pu that cannot continue to be recycled? After only one or two irradiations, Pu is not further usable in LWR MOX for isotopic reasons.

Oh that's right -- a vast fleet of accelerators and fast reactors will transmute every last gram of actinides. I forgot.

Just to refresh my memory, where have those technologies been demonstrated, and who's planning to pay for and build them commercially?

anonymous> Practically of the fission fragments isotopes can be used one way or another in industry and medicine. What is left is next to nothing, once the closed fuel cycle takes off.

FBRs were demonstrated, use Google. Who will build them is a silly question, in hundred years or so we have to switch to FBRs anyways. Storing spent fuel for that time in dry storage is trivial, well tested and demonstrated to be extremely safe.

These silly remarks make me furious, as compared to waste issues of any other power producing technology, including wind and solar, these are rather trivial issues in terms of volume and safety.

No, thorium and the liquid-fluoride thorium reactor is a viable alternative to fast breeders that does not require a fast spectrum and does not require plutonium.

The absorption cross-sections of actinides are SO much greater in the thermal spectrum than in the fast spectrum that only a thermal-spectrum reactor can attain its most reactive configuration -- which is a very important safety consideration.

...and BTW, how does he propose shipping it safely over to "them", not "us" air, sea...truck?? Thought our typical casks weigh 100 tons plus.

"Practically [all] of the fission fragments isotopes can be used one way or another in industry and medicine. What is left is next to nothing, once the closed fuel cycle takes off."

We've been waiting 60 years for the closed fuel cycle to "take off." And where's all this industrial demand for every isotope produced in HLW? Just not true.

"FBRs were demonstrated, use Google."

I'm aware they've been demonstrated. Every FBR ever built has experienced serious technical problems. None has ever been commercialized. None has ever been built as a private commercial enterprise, rather than as a heavily subsidized government research program.

FBRs get built, they break and leak sodium, they get shut down. Use Google yourself.

And read more carefully -- I was saying that partitioning and transmutation has not been demonstrated on anything approaching a commercial scale.

"Who will build them is a silly question, in hundred years or so we have to switch to FBRs anyways."

"Have to"? Says who?

Also, the need for something isn't proof that it will happen. the nuclear industry's been saying we need new plants in the US for decades, and it's only now getting underway.

Sarcasm and dismissive overgeneralizations do not constitute dialogue.

LMFBRs get built, they break and leak sodium.

FBRs are a far more general category.

Important distinction.

I grant that most FBRs up to this point have been LMFBRs, but I don't think that's the right direction to go in future FBRs.

"FBRs are a far more general category."

That's a fair point.

So please list all non-liquid metal FBRs that are 1) operating, 2) under construction, or 3) have been demonstrated on a commercial scale.
Kirk Sorensen said…
Doesn't matter if they've been built or operated. You made the point yourself, which I agree with, that liquid-metal cooled FBRs are troublesome beasts that have a poor record.

We need to go a totally different direction in future FBRs, towards safety, simplicity, and versatility.

"Doesn't matter if they've been built or operated."

Does if you're touting them as a viable medium-term solution to a whole host of problems, as some are here.

It also speaks volumes that most of these non-liquid-metal FBR designs have been around since the 1950s, yet most have never even been built on an experimental scale. Solving equations for a system flowsheet on a computer is not the same as a technically viable design, but the labs being paid to come up with these visions would sure have us think so.
Kirk Sorensen said…
No, the labs just want to build LMFBRs.

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

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…
