The American fusion effort needs help to defend against planned budgetary destruction.
“Bigger Contribution to ITER Erodes Domestic Fusion Program” is the headline in this week’s Science Magazine report by Adrian Cho. It refers to the 2013 budget decisions at the political level in the US. We have discussed Science magazine before; its section on current news is outstanding. Maybe the best chronicle of the American decline in front-line science capabilities, both scientific exploration and technical development.
LastTechAge has discussed fusion before, and here is my standard disclosure: I am a physicist who at one time worked in the fusion energy program at General Atomics.
We are on the edge of a deep drop-off, but it may be hard to step back and see where the problem is. After all, the DOE Fusion division got 99% of its 2013 request for funds. Stay with me, this budget stuff does get interesting.
The diagram shows what looks like a lot of money flowing into fusion programs but tiny streams into the US labs and into ITER. This is because the amount to flow into both are insufficient for either one; we are threatened with the death of both ventures.
The problem is that, to stay in play, we must pay larger ‘dues’ to the international ITER ignition machine being built in France. The ITER support fund rose by 43% to $150M while support for American fusion labs is decreased “a little” to $248M in 2013 dollars.
Two problems with the budget
- ITER costs have gone up and our actual bill in 2013 or 14 will be close to $300M (a 2× shortfall). We will feel push-back from the financially stressed rest of the world. And soon.
- The US labs were previously at the precipice edge of funding; massive reductions in capability must follow any new reduction. And quickly.
ITER (pronounced ‘eater’ in the European way) is the next necessary step in fusion research. The ITER design was proposed in late 1988, but was not seriously considered until the 2000s. It is very expensive, but almost certainly will produce an ignited plasma. Without ITER, there is really no reason to continue with fusion research.
ITER is very similar to the INTOR proposal of the 1980s which was an outgrowth of many earlier proposals. This step is needed and will almost certainly work as planned. Why were neither INTOR nor ITER not funded at that time? Tough question – both then and now.
The US has been an inconstant supporter of fusion power. We had important wars to fund and fortunes to make; our power leaders were not very interested. Due to the massive postponements the machine is more expensive than it used to be. If we were to owe the ITER program our entire annual budget for fusion research, will we stay on the course?
Consequences on American Fusion Labs
The U.S. fusion labs are in deep trouble and every lab currently operating will feel the hit, some more than others.
Alcator C-mod, will close. C-Mod is located at the M.I.T. Plasma Science and Fusion Center (PSFC) This is the only American high magnetic field fusion study facility and, as associated with the university, is a premier training site for the next generation of scientists.
The machine is small due to its huge magnetic field strength. Its goal is to find ways to simplify and reduce the cost of the ITER follow-on.
Miklos Pokolab, the PSFC Director, said this that will eliminate 100 fusion staff members and 30 graduate students. Its loss will be a heavy blow to the American effort. Pictures, courtesy of MIT website.
NSTX upgrade will be delayed. The National Spherical Torus Experiment is a government facility operated by the Princeton Plasma Physics Laboratory (PPPL). PPPL is the site where plasma experimentation was born. The ST machine will stop operating within the next several weeks, so that it can undergo a major upgrade for enhanced performance.
A spherical tokamak (shaped like an ‘apple with an extremely thin core’) avoids many of the expensive problems of traditional tokamaks. This system was proposed 30 years ago and has been operational (with many modifications and upgrades) since the late 1990s. It was born as an attempt to demonstrate feasible containment and heating in a device much smaller and cheaper than a usual tokamak. There are now an international community of ST-like machines, each looking at a piece of the main problem. Success of this concept would have huge leverage on the power generating follow-on to ITER.
Stewart Prager, PPPL Director, reports that they will have to eliminate 100 staff positions. The post-upgrade restart will be delayed by at least 6 months. In light of the horrible funding situation, I fear this may be optimistic. If our ITER dues match total DOE fusion budget, this extraordinarily far sighted experiment may be forced to close.
DIII-D will operate on a reduced annual schedule. This is the workhorse of American fusion experiments. It is the device that demonstrated the superiority of D shaped plasmas, well before its 1986 upgrade to the ‘-D’ modification.
Tony Taylor, V.P. of the Magnetic Fusion Energy Division at General Atomics says that they will be forced to reduce operations to 10 weeks a year. This is less than half of the 24 weeks that should be considered the minimum operation time of a machine like this. They will have to reduce staff from their current 180 to 150 positions. The reductions would impact the measure of DIII-D’s “cost effectiveness.”
Even so, DIII-D will be the U.S.’s only operating general magnetic fusion facility in 2013. DIII-D is a user facility, where scientists around the nation and the world come to conduct tests with strong implications for ITER success. It is smaller than the European JET facility but highly productive. Images from the DIII facility are also shown on the LastTechAge header strip.
Is the new budget a final effort to bury fusion?
We no longer have the large dedicated set of American labs functioning as world leaders in fusion technology. At one time we had many; one by one most experimental labs have been dismantled. But the promise is still real.
- ITER is absolutely required become operational and generate a baseline of data for ignited fusion devices. The President’s Science Advisor, John Holdren agrees with the fundamental need to see ITER operate. “The cutting edge of fusion is determining whether we can create a burning plasma, and the only machine in the world that has a prospect of doing that is [ITER].”
- One short-term budget point proposed by DOE – send our fusion experts to work at facilities in other countries. I am sure that, if we asked real nice (and paid), China would let our physicists contribute to their soon-to-be-outstanding laboratories. But, sending people offshore is not a way to long term success.
- We must not just offshore our expertize.
Martin Greenwald (MIT physicist and Chair of DOE’s Fusion Energy Sciences Advisory Committee) says we must keep on the front-line of fusion studies, do cutting edge experiments and train new researchers, “otherwise, you’re just building a piece of equipment for other people to use.” I think ‘piece of equipment’ means ITER and ‘other people’ means China, Japan, India, the EU, Brazil, Canada, … you know, those upcoming countries that fully intend to be part of future fusion energy supply.
William Brinkman, Director of DOE’s Office of Science is quoted “it makes no sense to invest in ITER if there isn’t a base program.”
Tony Taylor (GA) says “It makes no sense for the United States to pay to ship our intellectual capital overseas and make ourselves less competitive.”
(All quotes here are from the high-impact Science article.)
Fusion energy research has undergone systematic and steep reductions during the last 30 years. If you follow LastTechAge posts at all, you will know that in our Inequality series, we established that a dramatic process started just a bit more than 30 years ago. Income for the top earning 0.01% of the population (our ultras) suddenly expanded by a factor of 5 (400% growth), the Process has forced the rest of us to loose income share. Fusion studies is one of the future directed projects hurt early in those 30 years while the Process operated. We knew something strange was happening but could not identify any ‘who’ or ‘why.’ Personally, I think it reasonable to see these time associations as correlated events. We currently seem to be at the Process‘s coup de grâse point for fusion energy – the final step to disintegrate real American participation in fusion technology.
The battle is not yet lost. This budget still has to go to Congress, which has the power to change it. But, until good news arrives, I use my standard sound bite: “Yes, fusion energy is highly feasible, and the time to grid power is probably never.”
Update: The U.S. fusion effort will be thrown into twilight darkness if the current budget proposal become law. If you are concerned about the future, read the comments to our original posting., then click to http://www.fusionfuture.org/. This is not about jobs for intellectual elite. It is about how American society will get the energy needed to“maintain this, the last technical civilization of our world.”
http://www.fusionfuture.org/ is by the MIT graduate students making active effort to protect their dreams, more importantly, to protect America’s future as one of the leaders of human society.
What is the alternative?
My summary: We will…
- …lose future options for high power generation
- …try to keep energy available by fracking for oil, tar sand liquids, and natural gas, destroying continental water storage and food producing croplands.
- …use lignite-fueled power stations with damaging emissions
- …build fission reactor plants with radioactive waste and no viable long term solutions… read “destructive future spills that form wastelands.”
- …end up with a dual level society – rich elite with access to all the life extending drugs and techniques, and a massively large population in poverty that provide cheap labor but with high infant mortality, and short lifespans.
This is not the time to smooth our imagery, we are starting down this dark path right now. If we are to “maintain this, the last technical civilization of our world,” all concerned people must contact their congress men and women. http://www.fusionfuture.org/
