USA’s pro nuclear Blue Ribbon Waste Commission rejects nuclear reprocessing

The good news: The BRC rejects reprocessing for now. The report states: “No currently available or reasonably foreseeable reactor and fuel cycle technology developments—including advances in reprocess and recycle technologies—have the potential to fundamentally alter the waste management challenge this nation confronts over at least the next several decades, if not longer. 

Waste Commission rubberstamps more nuclear, but rejects reprocessing – for now Beyond Nuclear 30 July 11, A year and a half after its creation, on July 29th Energy Secretary Chu’s “Blue Ribbon Commission on America’s Nuclear Future” (BRC) has published its draft report of recommendations for dealing with the mountain of U.S. high-level radioactive waste now nearly 70 years high.

China touts ‘fast breeder’ nuclear reactor, but it’s an unlikely energy solution

the process hasn’t proved workable on a large scale elsewhere. Fast-breeder programs have been abandoned in a number of countries, including the U.S., and the plants that remain are small.

China’s Nuclear Scientists Unveil Latest ‘Breakthrough, WSJ, James T. Areddy, 21 July 11, “…..The China Institute of Atomic Energy said Thursday that a small, experimental “fast breeder” reactor outside Beijing had been hooked to the grid to produce electricity. …. Continue reading →

Thorium nuclear reactors not effective, not a viable technology

‘Even if thorium technology does progress to the point where it might be commercially viable, it will face the same problems as conventional nuclear: it is not renewable or sustainable and cannot effectively connect to smart grids. The technology is not tried and tested, and none of the main players is interested. Thorium reactors are no more than a distraction.’

Don’t believe the spin on thorium being a ‘greener’ nuclear option, The Ecologist, Eifion Rees,  23rd June, 2011 “………China, Russia, France and the US are also pursuing the technology, while India’s department of atomic energy and the UK’s Engineering and Physical Sciences Research Council are jointly funding five UK research programmes into it.

There is a significant sticking point to the promotion of thorium as the ‘great green hope’ of clean energy production: it remains unproven on a commercial scale. While it has been around since the 1950s (and an experimental 10MW LFTR did run for five years during the 1960s at Oak Ridge National Laboratory in the US, though using uranium and plutonium as fuel) it is still a next generation nuclear technology – theoretical.

Japan might suspend developing its troubled fast breeder reactor

Unlike regular light-water reactors fueled by uranium, the Monju reactor, operated by the Japan Atomic Energy Agency, runs on an oxide mix of plutonium and uranium, or MOX, made from spent nuclear fuel from existing plants.

The reactor first achieved criticality in 1994, but was shut down due to a serious accident involving a leak of sodium coolant and a resulting fire in 1995.

Science minister says gov’t will mull halting Monju prototype reactor project, Mainichi Japan) July 15, 2011TOKYO (Kyodo) — Science minister Yoshiaki Takaki indicated Friday that the government will consider suspending the development of the prototype fast-breeder reactor Monju in the wake of the country’s worst nuclear crisis that continues at the Fukushima Daiichi power plant.

Safecast – citizen scientists monitor Japan’s radiation levels

Safecast took its first reading on April 16. Today, it has about 50 regular volunteers who collect data from their homes or while driving, build devices or assist in other ways. Those using vehicles equipped with Geiger counters cover an area that Franken estimates to be about 620 miles long by 185 miles wide. To date, they’ve collected 251,000 data points from their drives and fixed reporting stations, and have received about 60,000 more from other sources, including people with their own Geiger counters.

Japan’s citizen scientists map radiation, DIY-style, World Blog, By Miranda Leitsinger, Senior Writer and Editor, msnbc.com  13 July 11, With the Japanese government only providing spotty information about the radiation leaking from the damaged Fukushima nuclear plant in the early days after the devastating March 11 earthquake and tsunami, a group of tech-minded citizen scientists set out to fill in the “black holes” in the knowledge base.

USA’s Aerial Radiological Survey – testing radiation levels in the atmosphere

Now You Know: That Thing in the Sky is Testing for Radiation, Seattlest 13 July 11  If you’ve recently spied a startlingly low-flying beast in the sky, don’t worry–it’s not Google trying to get a more recent photo of your back yard, and it’s not a search party looking for bad guys in your neighborhood. It’s just trying to get a read on how much radiation you might exposed to.

Yesterday, the Washington State Department of Health launched the Aerial Radiological Survey for King and Piece Counties. The survey, which is being conducted by a helicopter that flies in a grid pattern at about 300 feet above the ground, will last until July 28. It is being funded by the Department of Homeland Security, and can “detect the presence of radioactive materials that emit gamma radiation such as cesium and radioactive iodine.” The goal of the project is to establish a radiation baseline–that is, how much radiation each area is exposed to right now, in a time of normal levels.

The project, says the DOH, has been in the works since 2009. But, we imagine, since the Fukushima nuclear disaster across the pond in Japan, the information being gathered is more critical than they could have predicted. Having a baseline for what is “normal” will be massively helpful in the future, when determining what is dangerous, and what is abnormal….http://seattlest.com/2011/07/12/now_you_know_that_thing_in_the_sky.php

Stuxnet computer worm ushers in new threat to nuclear installations

STUXNET: WORLD’S FIRST CYBER WEAPON, Big Think   July 12, 2011 .When the Stuxnet computer virus infected Iran’s nuclear power facilities at the Natanz enrichment plant, it became the world’s first cyber weapon…..”Stuxnet required an enormous amount of resources to produce, but its cost-benefit ratio is still in question. While it may have helped set Iran’s program back to a degree, it also altered the landscape of cyberattacks. Stuxnet’s authors mapped a new frontier that other attackers are bound to follow; and the next target for sabotage could easily be a nuclear facility in the United States. No one knows what Stuxnet might have achieved had it never been discovered by VirusBlockAda a year ago. … It appeared the attackers were still developing the code when it was uncovered.”..http://bigthink.com/ideas/39255

Long Branch Center refutes any need for USA nuclear reprocessing

Reprocessing in the United Kingdom has been an abysmal failure, and Russia continues reprocessing with no use of separated plutonium, and all European countries have now withdrawn from reprocessing in France and France reuses little of the contaminated uranium removed via reprocessing, and the $20 billion Japanese reprocessing plant Rokkasho has failed to start after more than two years of attempts. The disastrous U.S. experience with commercial reprocessing at West Valley, New York, from 1966-1972 was a total failure which contaminated the environment and resulted in a multi-billion dollar clean-up program that is still proceeding, revealing that the NRC must guarantee that all costs of operation, clean-up and potential accidents must be must be guaranteed by license holders, not by the Federal Government or taxpayers.

Too late for a well-managed shutdown of Indian Point nuclear plant?

Three options to replace Indian Point stand out. One, local fossil fuel sources such as natural gas could generate more electricity. Two, excess hydroelectric power or wind power generated upstate or in Canada could be transported downstate. And three, consumers could drastically cut their electricity use.

All appear relatively simple and, together, offer promise. But closer inspection shows there is a great deal of complexity involved……

Has Time Run Out to Replace Indian Point’s Nuclear Power? Reuters, 8 July 11, By Alice Kenny, SolveClimate News   Editor’s Note: In this three-part series, SolveClimate News examines the feasibility of closing the Indian Point nuclear facility in Buchanan, N.Y. The plant, now up for relicensing, faces demands for a shutdown by Gov. Andrew Cuomo and many environmental groups. This is part two.

Renewed backlash against New York’s Indian Point nuclear plant in the wake of Japan’s disaster has forced politicians and energy experts in the state to again confront tough questions about how to permanently replace the facility’s electricity.

Now, with the plant up for relicensing, some observers warn that time may have run out for a well-managed and gradual shutdown of the complex, located just 24 miles from America’s most populous city…… Continue reading →

Russia’s nuclear-powered ice-breaker ship

The Soviet Ship That Cuts Through Ice Like a Nuclear-Powered Knife Through Butte, Wired.com, By Andrew Tarantola, Gizmodo.com  , July 8, 2011 ………who else would think to pack two nuclear reactors into a ship and set it loose in the Arctic breaking ice? The North Koreans? Psshhh, not likely…….”

…..Breaking with the Soviet tradition of intuitive, straightforward design, the reactors are used to power Rube Goldberg propulsion system. The reactors power boilers which generate high pressure steam to power 12 dynamos which in turn power electric motors attached to each of the three propeller screws. These motors provide each screw with roughly 25,000 horsepower or 55.3MW. With that much power, the Yamal punches through ice up to 2.3m thick at a speed of 3 knots. And though the Yamal’s maximum rated ice thickness is 5m, it has been recorded smashing individual ice ridges as thick as 9m…

….Despite its ability to break through 20 vertical feet of ice at a time, the Yamal is effectively trapped in the Arctic. Because the reactors use the area’s frigid water for cooling, the Yamal is physically incapable of traveling near (and definitely not past) the equator without overheating and melting down its fuel supply.  ….

Radiation – the big safety hazard for nuclear reactors themselves

Radiation bombards reactors, make them brittle, Google News By JEFF DONN, AP National Writer –20 June 11 No aging problem has been more vexing or dangerous in nuclear power plants than the tendency of reactors to grow brittle. This stubborn problem threatens the main radiation barrier at the plants: the garage-size steel vessels that cradle tons of radioactive fuel.

In certain emergencies, these vessels would flood with cooling water. If the vessel walls are too brittle, they could shatter and spew their radioactive contents into the environment. Continue reading →
