Bill Gates’ firm Terrapower discuss nuclear reactor plan in China

China is set to start work on a novel design for a nuclear reactor with the help of a firm founded by Bill Gates.
Terrapower, founded and funded by the Microsoft chairman, is collaborating with Chinese scientists on the fourth generation (4G) reactor. Research into the 4G reactor over the next five years could top $1 billion, said Mr Gates. Developing such a reactor could take a long time because none have been built or tested yet.
“The idea is to be very low cost, very safe and generate very little waste,” said Mr Gates during a talk at China’s Ministry of Science and Technology during which he confirmed the tie-up with Terrapower…
Based in Washington state, Terrapower is working on a design for what is known as a travelling wave reactor. This uses depleted uranium as its power source and is believed to produce less nuclear waste than other designs.
“All these new designs are going to be incredibly safe,” Mr Gates said. “They require no human action to remain safe at all times…”
I’ve supported nuclear power generation since I first worked in the field before most of my readers were born. Cripes, I never thought I’d get old enough to be able to say that.
Anyway, in recent years I have gradually begun to shift my alliance to large-scale solar power projects because I feel the ultimate cost of producing electrical power is now less for solar technology than nuclear power. The environmental problems associated with the latter methodology are problems of politics, corruption and laziness prompted by greed. Problems faced by all large-scale endeavors in the modern era.
If Gates’ company can beat the costs of competing with large and small-scale projects from advanced firms like Toshiba and Areva – well, then, more power to him.
Renewables exceed 20% of Germany’s energy production

In the wake of the Fukushima Daiichi nuclear disaster, tens of thousands of German citizens took to the streets calling for the phase out of atomic energy. In May, the German government bowed to public pressure and unveiled its plan to shut down the country’s 17 nuclear power plants by 2021 – with the possibility that three will continue operating until 2022 if the transition to renewable energy doesn’t go as quickly as hoped.
Providing some hope that Germany will achieve its ambitious goals, Spiegel Online International has quoted a newly released…report that says, for the first time, renewable sources accounted for more than 20 percent of the country’s electricity generation…
According to the report, renewable energy sources provided 18.3 percent of total demand in 2010, but the first six months of 2011 saw that figure rise to 20.8 percent, while Germany’s total usage remained steady from 2010 at 275.5 billion kilowatt hours…

Of the 57.3 billion kWh provided by renewable sources in the first six months of 2011, wind power was the dominant source supplying 20.7 billion kWh (7.5 percent of total production), followed by biomass with 15.4 billion kWh (5.6 percent), photovoltaic solar with 9.6 billion kWh (3.5 percent), hydroelectric with 9.1 billion kWh (3.3 percent, and waste and other sources providing 2.2 billion kWh (0.8 percent).
Solar power saw the biggest jump, increasing by 76 percent over 2010 with the BDEW citing the reduction in the price of photovoltaic installations as a result of increased competition and the decision of the federal government not to cut subsidies for private solar-power generation as initially planned as the main reasons for the increase.
“Because of the volume of new photovoltaic installations and the amount of sun during the spring, solar energy knocked hydroelectric from third place for the first time,” said the BDEW.
Two points worth making. First – the economies of scale really play well with photo-voltaics. It’s a technology where small but noticeable advances are being made in both cost of production and efficiencies of energy production. Second – German voters are already sophisticated enough to ignore the hypocrisy of fossil fuel facility builders who whine about continued subsidies. Fact is – all fossil fuel plants rely on taxpayer subsidy for construction. There’s little difference in passing along subsidies to consumers with home installations.
I spent most of the past half-century as an advocate for nuclear power generation. From early days working in the field, it was clear that properly-run there was no need for safety concerns. Over that time the only disasters which have occurred were the result of bureaucratic malingering. Which can happen in any industry. The difference being that falling-down stupid about safety with nuclear power can be fatal on a large scale.
More important, we’ve just about reached the point where the cost of production of electricity via photo-voltaics matches the cost of construction and production of nuclear facilities. That will continue to diminish while the opposite happens with nuclear projects. And there will never be shutdown dangers associated with natural disasters using photo-voltaics.
China may double domestic solar power goals

China, the world’s largest solar panel exporter, is likely to boast 10 gigawatts of solar power capacity by 2015 from the current 1 gW, doubling its existing target amid rising doubts about the safety of nuclear power.
The country may double its target for solar power capacity to 10 gW in 2015 from the 5 gW originally planned the China Securities Journal reported on Wednesday, citing unnamed sources…
Meanwhile, China consolidated its position as the No 1 country in clean-energy investment in 2010, with $54.4 billion flowing into the sector, up 39 percent from the 2009 level, according to a report by the US-based Pew Charitable Trusts, an independent, non-profit organization. In 2009, China overtook the United States as the No 1 nation for installed clean-energy capacity…
China’s installation of less than 1 gW of solar energy capacity demonstrates that most of its production is for the export market. In contrast, 17 gW of wind energy was installed in China in 2010, helping the nation move quickly toward its 2020 target for installing 150 gW of wind energy, the report said…
“The new target could be a relief for China’s overcapacity photovoltaic (PV) industry,” said Li Shengman, an industry analyst at China Investment Consulting. The export-dependant industry will see the domestic market expanding, Li said…
China is home to the world’s top solar makers, including Suntech Power Holdings Ltd and Trina Solar Ltd all of whom have focused on the overseas markets while expecting a domestic market take-off.
It doesn’t especially matter to the manufacturers whether they’re selling to the government of China or to national-level builders of sun-farms in other lands. Product is going out the door.
What this disaster in Japan caused me to reflect upon is a comparison of all costs associated with electricity production from the two methods: solar vs. nuclear. And that, I discovered, gives an economic edge to solar of almost 30%.
Tokyo Electric Power company admits missing safety checks

The power plant at the centre of the biggest civilian nuclear crisis in Japan’s history contained far more spent fuel rods than it was designed to store, while its technicians repeatedly failed to carry out mandatory safety checks, according to documents from the reactor’s operator…
According to documents from Tokyo Electric Power (Tepco), the company repeatedly missed safety checks over a 10-year period up to two weeks before the 11 March disaster, and allowed uranium fuel rods to pile up inside the 40-year-old facility…
The revelations will add to pressure on Tepco to explain why, under its cost-cutting chief executive Masataka Shimizu, it opted to save money by storing the spent fuel on site rather than invest in safer storage options.
The firm already faces scrutiny over why it waited so long to pump seawater into the stricken reactors and, according to a report in the Yomiuri Shimbun newspaper last week, turned down US offers of help to cool the reactors shortly after the disaster.
Critics of Japan’s nuclear power programme say the industry’s patchy safety record and close ties to regulating authorities will have to change if it is to regain public trust…
One month before the tsunami, government regulators approved a Tepco request to prolong the life of one of its six reactors by another decade, despite warnings that its backup power generator contained stress cracks, making them more vulnerable to water damage.
Weeks later, Tepco admitted it had failed to inspect 33 pieces of equipment inside the plant’s cooling systems, including water pumps, according to the nuclear safety agency’s website…
When disaster struck earlier this month, the plant contained almost 4,000 uranium fuel assemblies kept in pools of circulating water – the equivalent of more than three times the amount of radioactive material usually kept in the active cores of the plant’s reactors.
And like the First and second-generation nuclear plants in the United States – those uranium fuel rods could have been recycled. Beancounters in charge? You can almost be guaranteed that cost was more important than efficiency – or safety.
Here comes the backlash to the nuclear part of Japan’s disaster

There’s a lot that will be gleaned over the coming weeks and months from Japan’s nuclear “disaster.” It’s a pretty big nuclear fail, on par with Three Mile Island… It’s been at the front and center of global media and policy debates this weekend, and it’s an ongoing situation.
The latest is that Japanese authorities have reportedly said there’s a significant chance the fuel rods have partially melted at two of the reactors, and they are still fighting a full-blown meltdown. The operator of the reactors…resorted to pumping seawater into the reactors, which to many in the industry sounds very much like a last-ditch, worrisome effort. Reuters reported 140,000 people have been evacuated from the area as a safety precaution, and iodine is being readied to distributed to people in the area to protect them from radioactive exposure. We’ll soon see if the disaster will get worse or better.
What we do know is that the incident could have far-reaching repercussions on the nuclear policies of the governments of the U.S., European countries, China and India, and will likely do significant damage to public opinion in general of nuclear energy. As the Guardian put it succinctly: “When experts decide it is necessary to flood reactors in the world’s most technologically advanced nation with an improvised flow of marine muck, people will ask whether the industry’s contingency planning for disaster is really as good as we are always being promised.”
Already, anti-nuclear groups are already using the incident to point to the dangers — or at least unknowns — of nuclear…and beyond the public relations nightmare of the dangers associated with nuclear, costs are as much of a concern. Not just to build the plants, but also to deal with any nuclear problems. According to the World Nuclear Association, the cleanup of the damaged nuclear reactor system at Three Mile Island took nearly 12 years and cost approximately $973 million.
Katie Fehrenbacher’s cost concerns are legitimate and should be central to any revision and upgrading of planned nuclear power facilities. Though the old policies with rule of thumb of planning for an 80% chance of disaster already are passé in most nations. Now, here’s what we’re witnessing:
Say, your next-door neighbor has a 1979 Oldsmobile diesel. One of the worst crap engines ever put into production. The engine blows up while he’s in his driveway one morning. Since it’s only a gravel over dirt driveway, all the oil and crud sinks into the soil potentially reaching groundwater and affecting the wells of all his neighbors.
Because of that incident, no one should ever consider buying a new car with a low-emissions, high-efficiency diesel engine from Volkswagen, BMW, Mercedes, Audi or any other builder of diesel-powered cars offered around the world.
That’s just about a perfect analogy to what we’re about to witness over consideration of nuclear generation of electricity – because of what happened at a power plant designed in the 1960′s, built in the 1970′s that just suffered through an earthquake and tsunami beyond the specification for its construction.
Colorado’s uranium struggle makes for tough decisions

The canyon floor – former uranium mining area near my home
NATURITA, Colorado — The future of nuclear power in America is back on the table, with all its vast implications, as global warming revives the search for energy sources that produce less greenhouse gas.
But in this depressed corner of western Colorado — one of the first places in the world that uranium, nuclear energy’s primary fuel, was ever dug from the ground in industrial scale — the debate is both simpler and more complicated. A proposal for a new mill to process uranium ore, which would lead to the opening of long-shuttered mines in Colorado and Utah, has brought global and local concerns into collision — jobs, health, class-consciousness and historical memory among them — in ways that suggest, if the pattern here holds, a bitter national debate to come…
To residents here like Michelle Mathews, the fact that many opponents of the mill hail from Telluride is a crucial strike against their arguments.
“People from Telluride don’t have any business around here,” said Ms. Mathews, 31, who works as a school janitor and ardently supports the idea of bringing back uranium jobs. “Not everyone wants to drive to Telluride to clean hotel rooms…”
“They say it’s going to be different this time around,” said Craig Pirazzi, a carpenter who moved to the Naturita area from Telluride a few years ago and is now a member of the Paradox Valley Sustainability Association, which opposes the mill. “But our opposition to this proposal is based on the performance of historic uranium mining, because that’s all we have to go on — and that record is not good.”
Supporters, meanwhile, say that the opponents of Piñon Ridge are guilty of promulgating ignorant fears about something they do not understand…
“They’re saying not in my backyard — now how big is their backyard?” said George Glasier, a local rancher and investor who founded Energy Fuels, the company proposing the mill, and is now a stockholder and consultant. Energy Fuels is a publicly traded company based in Canada; a United States subsidiary would operate the mill.
I hate to say both sides have legitimate points; but, relying on past worst practices to describe how 21st Century mines and mills will be run is not only lousy politics and logic – it begs the question of critics taking responsibility to fight for best practices when the mines and mills reopen.
Historically, I condemn the whole nuclear power generation industry of the 50′s and 60′s because it was a boondoggle and welfare plan run as a cost-plus enterprise to subsidize American corporations. Regardless of the cost in human lives.
I lived in the Navajo Nation with families carrying 2 generations of genes destroyed in sleazy uranium mines. But, I also worked in a building in Connecticut used to clad uranium power rods – and there wasn’t a speck of uranium found when we moved in and I get checked every 10 years by the Feds [if I wish to be] with no sign of illness from that period.
We live several miles from a closed uranium claim and, again, upstream where we are – and downstream at a tiny community around 400 years old – there has been no trace of radiation-related illness. The processes needn’t be destructive. And we the people have as much a responsibility – maybe more of a commitment – to keep things that way. That doesn’t include being a Luddite.
Vietnam signs major nuclear power contracts

Dimitry Medvedev and Nguyen Minh Triet celebrate the contract signing
Daylife/AP PHoto used by permission
Russia and Vietnam on Sunday signed a deal worth an estimated 5.6 billion dollars for the energy-hungry Southeast Asian country’s first nuclear power plant…
An official with Russian state nuclear conglomerate Rosatom has told AFP the construction cost of a two-reactor plant is estimated at more than four billion euros…
Vietnam wants to build eight nuclear facilities in the next two decades. Initial government plans call for four reactors, with a total capacity of 4,000 megawatts and at least one of them operational in 10 years’ time.
Sergei Kiriyenko said a 2020 timeframe for the Russian plant was “absolutely realistic”.
Russian President Medvedev earlier held talks with Vietnamese officials centred on expanding his country’s presence in Vietnam, which he said is “actively developing” on various fronts.
“On all these directions Russia will assist Vietnam, which is our close friend,” he said after paying his respects at the mausoleum of Vietnam’s revolutionary hero Ho Chi Minh…
Japan’s Prime Minister Naoto Kan, also on a visit to Hanoi, announced with his Vietnamese counterpart that the two countries will join forces to build two other nuclear reactors.
Moscow is willing to provide a loan to help finance the Russian plant’s construction…The two sides signed additional agreements on construction of a hydro power station and cooperation in the oil sector.
If the United States government, U.S. industry had brains located anywhere near their heads instead of the nether portions of their anatomy, we could have been providing those services to developing nations in Asia and elsewhere.
Back in the day, when I worked for a vendor to the nuclear power industry, I became fed-up with the policy of treating nuclear power generation as a short-term cash cow to supplement welfare for American capital goods producers. I quit. Went on to other aspects of metallurgy. Literature, Philosophy. Politics. You understand how that works.
When a couple of world-class safety screw-ups made nuclear power unpopular – and we had plenty of wars serving up supplemental income – our nation walked away from the dance. Leaving us decades behind productive commerce on the world stage.
Add to that the political history of America’s imperial adventures in the 3rd World…and you understand why there’s no American participation in any signing ceremonies like this.
Nuclear submarines sent to sea as potential floating bombs

HMS Turbulent docked in Plymouth
Two British nuclear submarines went to sea with a potentially disastrous safety problem that left both vessels at risk of a catastrophic accident, the Guardian can reveal.
Safety valves designed to release pressure from steam generators in an emergency were completely sealed off when the nuclear hunter killers Turbulent and Tireless left port, a leaked memo discloses.
The problem went undetected on HMS Turbulent for more than two years, during which time the vessel was on operations around the Atlantic, and visited Bergen in Norway, the Portuguese capital, Lisbon, and Faslane naval base near Glasgow.
It was not noticed on HMS Tireless for more than a year, and was finally detected last month, two months after Tireless started sea trials from its home port at Devonport naval base in Plymouth…
The Ministry of Defence memo, which was written last week, admits that both cases involving the sealed-off valves were “a serious incident” that raised major questions about “weak and ambiguous” safety procedures at Devonport dockyard and within the Royal Navy…
John Large, a consultant on nuclear safety who advises governments on submarine safety, said: “It was a very significant failure. These two submarines were unfit for service. It was a perilous situation.”
The excuse offered – and accepted – is that safety procedures are very complex. Seems to be a perfectly good reason for all the more care and oversight.
Nuclear power’s time has come!
![]()
For decades, pioneering environmentalist Stewart Brand, the founder and editor of the Whole Earth Catalog, opposed the use of nuclear power. Now he sees it as vital to efforts to combat climate change.
Earlier this month, Brand made the case for nuclear power in a debate with Stanford University professor Mark Jacobson at the TED Conference in Long Beach, California. (TED is a nonprofit that stands for technology, information and design and is dedicated to “Ideas worth spreading.”)
His outspoken support for nuclear power comes as the White House has been pushing for the first new nuclear plants in the United States in three decades…
Brand says his turnabout began in 2002, when the Global Business Network, a consulting organization he co-founded, did a project on climate change for the U.S. Secretary of Defense. In an interview with CNN.com, Brand said the project showed him that the globe’s climate can change abruptly: “It goes over some tipping point and suddenly you’re in a situation that you don’t like and you can’t go back. That got me way more concerned about climate as a clear and present danger than I had been.”
Looking for a surefire way to cut greenhouse gases, Brand said the alternative to burning coal became clear: “We already had a very good supplier of …electricity. It worked like mad and was as clean as it could be — and that was nuclear.
“Looking at nuclear more closely made me look at coal more closely and I got to realizing what a horror it was across the board, and as I learned more about nuclear, I started learning all this stuff that my fellow environmentalists had been careful not to let me know about.”
Brand spoke to CNN.com Wednesday. Halfway down the page is the edited transcript.

Working days while studying engineering at night school, I was a technician in an R&D lab for a key vendor to builders of nuclear power plants starting back in the 1950′s.
I never had a problem with the science or safety solutions we were capable of within the nuclear power industry. Cripes, I still get checked-on every decade or so because the building I worked in had been the pilot plant for cladding uranium power rods. Never a peep after more than a half-century.
What turned me from support for the industry was the overwhelming corruption of cost-plus budgeting from Uncle Sugar. Guaranteed padding the cost of construction, manufacture, production – with diminished concern for quality control or modernizing design. It was a cash cow, a welfare plan for companies like Westinghouse.
But, knowledge and science advance even if politicians don’t. Other countries like France continued with new generations of design and fiscal oversight, kept the wheel turning. I’m pleased to see Stewart Brand never stopped learning.
Radioactive book reviews and irrational fear

Some books are written to be read, others to be put in a cannon and blasted at the seat of power. Two such blasts have just crossed my desk, from academics on either side of the Atlantic. Both are on the same subject, the consequence of the irrational fear of radiation.
The first book, Radiation and Reason, is by an Oxford professor of physics, Wade Allison. It narrates the history and nature of nuclear radiation, culminating in an attack on the obsessive safety levels governing nuclear energy. These overstate the true risk, in Allison’s view, by up to 500 times, thus rendering nuclear prohibitively expensive and endangering the combat of global warming.
The second is Atomic Obsession by John Mueller, professor of political science at Ohio State University. Mueller describes the toxic fear associated with radiation from nuclear weapons. It distorts the balance of international relations and senselessly makes enemies of friends. The books jointly undermine conventional wisdom on the two greatest political challenges of the day, in the fields of energy and defence. As such, they are sensational.
Radiation, says Allison, is nothing like as dangerous as the anti-nuclear lobby and its paranoid regulators claim. The permitted radiation level in the waste storage hall at Sellafield is so low (1 mSv per hour) as to be negligible, a figure achieved at vast cost in construction and inspection. This compares with the 100 mSv threshold for even remote cancer risk and 5,500 for radiation sickness. According to Allison, someone would have to live for a million hours in Sellafield to absorb the same radiation as is administered in a hospital radiotherapy suite. Higher doses are permitted in food processing and even in medicinal resorts, with supposed beneficial or at least harmless effects…
Meanwhile, over in Ohio, Mueller describes the same terror infecting reaction to nuclear weapons. He points out that nuclear bombs are extremely hard to make, let alone deploy, and their destructive power and radiological aftermath are grossly overstated. The devastation of Hiroshima and Nagasaki was largely the result of the buildings bombed being made of wood. Numbers killed were similar to those dying in conventional bomb attacks at the time. Yet we memorialise Hiroshima but not Tokyo, where 100,000 were killed in March 1945…
As for the much-vaunted risk of a terrorist getting a nuclear weapon – the “1% chance” that kept poor Dick Cheney awake at night – Mueller points out that the chance must be not one in a hundred but one in millions. Cheney would have done better worrying about the proliferation of AK47s…
This is all a massive failure of science to pierce the carapace of public ignorance. As Allison and Mueller argue, nothing is as potent as the politics of fear, and there is no fear as blind as that which comes from a bomb and a death ray. So what is science doing? The world is in the grip of a prejudice from which nothing seems able to free it. At least these books try.
