Doing Our Part to Reduce the Deficit

Monday, February 14th, 2011

The United States is facing a budget deficit of $1.5 trillion this year, and the new Republican-led House of Representatives (where spending originates in the US government) is looking for ways to save money.

We in the thorium community have a significant idea for how the government can

  1. save $500 million dollars
  2. accelerate the development of LFTR
  3. help NASA explore deep space
  4. save thousands of lives from cancer

It’s pretty simple–cancel the Department of Energy’s plan to destroy the uranium-233 stored at Oak Ridge National Lab.

For over ten years, the DOE’s Environmental Management division has been implementing a plan from the Defense Facility Nuclear Safety Board (97-1).

According to the DOE-EM 2011 budget request (page 14):

The Oak Ridge National Laboratory maintains the Department’s inventory of Uranium-233 (U-233), which is currently stored in Building 3019. The FY 2011 funding request will continue design of a project that processes the U-233 material in preparation for future disposal. Benefits include reducing safeguards and security requirements and eliminating long-term worker safety and criticality concerns. Recent discoveries of structural integrity issues with Building 3019 and determination that a portion of the U-233 is unsuitable for disposal at WIPP will require significant design changes to the facility. EM plans to continue the design effort through 90 percent design in FY 2011. At that point, a new baseline for construction and operations will be established. This will ensure that the construction estimate will have the accuracy necessary to complete the project on schedule and within budget.

Here’s the monetary stats on this project, according to a table on page 65 of the budget plan:

Site: Oak Ridge Reservation
PBS Field Code: OR-0011Z
PBS Name: Downblend of U-233 in Building 3019
Prior Costs FY 97-2009: $138.809M
FY10 and Remaining Cost (Low Range): $222.040M
FY10 and Remaining Cost (High Range): $246.012M
Lifecycle Cost (Low Range): $360.849M
Lifecycle Cost (High Range): $384.821M

It’s not too late to save the uranium-233. Despite spending $130 million, the effort to actually destroy the U-233 really hasn’t begun yet. Never have I rooted so hard for a government contractor to go slow and perform poorly!

From page 132:

U-233 Downblend Contract: The contract for U-233 downblending and Building 3019 shutdown was awarded to Isotek Systems, LLC in October 2003, originally managed by the Office of Nuclear Energy Congress directed the Department in the FY 2006 Energy and Water Appropriations Act to transfer the management of this project to the Office of Environmental Management and to terminate the medical isotope production. The contract has been revised accordingly. Phase I covered planning and design, which was completed in July of 2007. The current contracting schedule is for enhanced 90% design, in which a detailed cost proposal will be provided with a revised baseline and data sheet.

FY 2009: $58M
FY 2010: $38.9
FY 2011: $50M

Downblending of the U-233 hasn’t begun yet. From what I have heard, the contractor (Isotek) plans to import enough depleted uranium (DU) to create a final mixture of DU and U-233 that has the same fissile content as natural uranium (0.7% U-235). Well, if you want your final product to have only 0.7% U-233, then you’re going to need to bring in 1400 kg/0.007 = 200,000 kg of depleted uranium, and that weighs a lot. I’m guessing that that is what is requiring expensive modifications to building 3019 to support all that weight. I don’t know–one can only speculate at what is going on.

This is a very expensive project to destroy a very valuable resource. Please ask your Congressman to put an end to this waste of taxpayer money and to direct the DOE to use the U-233 for LFTRs that will produce electrical power and valuable materials for NASA’s space exploration and cancer-fighting medical isotopes.

Here is a video presentation of how saving U-233 from destruction can help NASA explore space and help save lives from cancer.

Here are the slides from that presentation.

The DOE’s own Inspector General has begged them to stop, in order to preserve the valuable medical isotopes derived from the U-233 that can help fight cancer.

Here’s their report:

Meeting Medical and Research Needs for Isotopes Derived from Uranium-233

Should the Department of Energy (Department) carry out its disposition plans to dispose of its uranium-233, there is no assurance that a viable inventory of progeny isotopes (actinium-225 and bismuth-213) will be available to meet domestic medical and scientific research needs.

China Initiates Thorium MSR Project

Sunday, January 30th, 2011

The People’s Republic of China has initiated a research and development project in thorium molten-salt reactor technology, it was announced in the Chinese Academy of Sciences (CAS) annual conference on Tuesday, January 25. An article in the Wenhui News followed on Wednesday (Google English translation). Chinese researchers also announced this development on the Energy from Thorium Discussion Forum.




Led by Dr. Jiang Mianheng, a graduate of Drexel University in electrical engineering, the thorium MSR efforts aims not only to develop the technology but to secure intellectual property rights to its implementation.



This may be one of the reasons that the Chinese have not joined the international Gen-IV effort for MSR development, since part of that involves technology exchange. Neither the US nor Russia have joined the MSR Gen-IV effort either.

A Chinese delegation led by Dr. Jiang travelled to Oak Ridge National Lab last fall to learn more about MSR technology and told lab leadership of their plans to develop a thorium-fueled MSR.

The Chinese also recognize that a thorium-fueled MSR is best run with uranium-233 fuel, which inevitably contains impurities (uranium-232 and its decay products) that preclude its use in nuclear weapons. Operating an MSR on the “pure” fuel cycle of thorium and uranium-233 means that a breakeven conversion ratio can be achieved, and after being started on uranium-233, only thorium is required for indefinite operation and power generation.




Currently there is no US effort to develop a thorium MSR. Readers of this blog and Charles Barton’s Nuclear Green blog know that there has been a grass-roots effort underway for over five years to change this. The formation of the Thorium Energy Alliance and the International Thorium Energy Organization have been attempts to convince governmental and industrial leaders to carefully consider the potential of thorium in a liquid-fluoride reactor. There have been many international participants in the TEA and IThEO conferences, but none from China.



Chinese energy demand is growing rapidly, and despite the world’s largest campaign of new nuclear construction, the vast majority of Chinese power generation still comes from fossil fuels. China has abundant supplies of coal, but their combustion has led to some of the worst air quality in the world. The ability of thorium MSRs to operate at atmospheric pressure and with simplified safety systems means that these reactors could be built in factories and mass-produced. They could then be shipped to operational sites with standard transportation. Their thorium fuel is compact and inexpensive. Chinese rare-earth miners have been rumored to have been stockpiling thorium from rare-earth mining for years, and if this is true, the Chinese will have hundreds of thousands of years of thorium already mined and available for use.

The Chinese now have the largest national effort to develop thorium molten-salt reactors. Whether other nations will follow is an open question.

Google TechTalk Video: “Save the Uranium-233″

Friday, January 28th, 2011

On January 13th I had an opportunity to talk about how we could use the uranium-233 inventory at Oak Ridge National Lab to start LFTRs and produce the plutonium-238 that we need to power space probes to explore the solar system. We can also save thousands of lives from the unique radioisotopes that we would extract from uranium-233. I hope you enjoy the presentation:

Google TechTalk Slides: “Save the Uranium-233″

Friday, January 21st, 2011

Last week I had another opportunity to give a “TechTalk” at Google and I chose to spoke on how saving the uranium-233 inventory at Oak Ridge could allow us to produce power-generating radioisotopes to explore space and to extract life-saving medical radioisotopes.

The video might not be ready for a few weeks, so I wanted to go ahead and post the slides.

“Save the Uranium-233 to Save Solar System Exploration” (PPT with notes, 4.6MB)

I did things a little differently on this presentation than usual, with the slides consisting almost totally of images and a narration included in notes along with the slides. To enjoy the presentation more in the manner it was given at Google, I recorded a narration, which is a substantially larger download, but if you’d like to hear me telling the story this is probably the better one to watch/listen.

“Save the Uranium-233 to Save Solar System Exploration” (PPT with audio narration, 18.1MB)

I wasn’t terribly happy with the audio quality of the narration, so if anyone has better ideas or wants to re-record it with better equipment feel free.

Renting U-233 to Interested Nations

Monday, April 19th, 2010

I had an idea today–since U-233 represents something like a “catalyst” for the prolonged consumption of thorium in a LFTR, and since a LFTR can be built that has a unity conversion ratio (makes as much U-233 as it consumes), then perhaps a nation that developed a large supply of U-233 could “rent” it to nations that want to start LFTRs but lack the ability to get or make U-233.

In a similar manner to the nuclear waste fund (1/10th of a penny per kilowatt*hour) the nation that “rents” U-233 to another nation could levy a rental fee on the electrical energy produced with “their” U-233. That way, a small country like Singapore could build or buy LFTRs and operate them, and the nation like the US that “rents” the U-233 could gain from the operation. At the end of the rental period, the agreement would stipulate that the U-233 be “returned” or accounted for. For a unity-conversion LFTR, this should work.

The US has 1000 kg of U-233. Unfortunately, it’s still bent on destroying this precious resource. In the scenario I outlined at TEAC2 and a few days ago in a blog post, we will use LFTRs and chloride reactors to destroy HEU and plutonium and make lots of U-233 for more LFTRs. This scenario might provide other uses for U-233 outside of the United States.

Don’t throw away U-233!

Sunday, April 23rd, 2006

When I learned that the entire National Defense Stockpile of thorium (3216 metric tonnes) was slated for burial in the Nevada desert, that was bad enough. But this one really breaks my heart and hurts so much worse.

Uranium-233 is the ideal fuel to start a liquid-fluoride reactor, and there is a very little bit in the world, left over from different attempts to get a thorium-powered future going. Now the DOE is taking great pride in the fact they are going to throw it away. I can only comfort myself with the idea that if they knew how valuable this material is for starting a liquid-fluoride reactor, they would never do this.

It gets even worse–the $128 million that they plan to spend to “blend” down this little bit of U-233 could be used to progress liquid-fluoride reactors, which currently get about $40K a year under the DOE Gen-4 program. The fellow that gets the money tells me it’s enough to “answer the phone”.

And once blended with U-238, the U-233 will be unrecoverable (I’m sure this is what they want). We could not isotopically separate it like natural uranium, since it will be far, far too radioactive to introduce into a diffusion plant. So it’s gone–thrown away when it could have started a thorium reactor.

What a tragic loss and waste…
