Nuclear energy a fading dream

Energy dream fades in New Brunswick

  By Megan O’Toole, Canwest News ServiceAugust 27, 2009

“……………The $1.4-billion refurbishment of New Brunswick’s Point Lepreau nuclear generating station, home to the first Candu 6 reactor in the world, was undertaken with the mantra “on time and on budget” as its driving force. But unforeseen delays and cost overruns have since plagued to the project–already half a year behind schedule–with ratepayers on the hook for replacement power costs. Continue reading

Nuclear power a stumbling block to US Senators

Senators and climate McCain-Udall visit showed hope, problems
The Durango Herald  August 27, 2009

Sen. John McCain, R-Ariz., differs from many in his party in acknowledging the science underlying global climate change…………

Likewise, Sen. Mark Udall, D-Colo., deserves credit for rethinking his opposition to nuclear power, a stance that probably has little support among his fellow Democrats.

The problem is, the caveats both attach to their positions render them all but meaningless. And that says more about the reality of dealing with climate change than melting glaciers or dying trees………………. Continue reading

Over-exposure to ionising radiation


Americans overexposed to radiation
The News August 28, 2009
CHICAGO: Younger Americans are being exposed to worrisome amounts of radiation from medical scans that increase their risk of cancer, US researchers said late on Wednesday. They said the cumulative risk of repeated exposure to radiation from medical scans is a public health threat that needs to be addressed. “Even though the individual risk for any patient exposed to these kinds of doses may be small, when you add that up over millions of people, that can be a concerning population risk,” Dr. Reza Fazel of Emory University in Atlanta and colleagues wrote in the New England Journal of Medicine.

Edward Kennedy’s legacy for clean energy, and a clean environment

Sen. Edward M. Kennedy, champion of the environment and clean energy, dies at 77

Grist by Joseph Romm 26 August

“He was a great champion of progressive causes, and his death is a great loss,………..

His legacy on “Protecting the Environment and Promoting Energy Efficiency” is below.  How many Senators would even mention “energy efficiency” among their achievements?……

Promoting Energy Research and Development
In 2007, Senator Kennedy’s “America COMPETES Act” was passed by both chambers of Congress and sent to the White House to become law. That bill established an Advanced Research Projects Authority at the Department of Energy to be the focal point of federal efforts to support breakthrough research on new clean energy technologies.

In 2009, Senator Kennedy urged that funds from the American Recovery and Reinvestment Act be used to build a wind blade technology testing facility in Massachusetts, and in May 2009, Energy Secretary Steven Chu announced that $25 million of such funds will be available for the project at the Autoport in Charlestown.

Improving Energy Efficiency
Senator Kennedy was a strong proponent of increasing energy efficiency, which is an essential part of reducing greenhouse gas emissions. He was a long time supporter of programs like the weatherization assistance program and the Low-Income Home Energy Assistance Program that helps those most in need reduce their energy bills by improving home energy efficiency.

…. Kennedy Fought to Reduce Greenhouse Gas Emissions and Address Global Warming. During consideration of the FY 2002 Budget Resolution, Senator Kennedy cosponsored an amendment to reduce greenhouse gas emissions and address concerns related to global climate change. The amendment sought to promote voluntary programs for reducing emissions in the near term. In addition, Senator Kennedy’s amendment included provisions designed to assist developing countries in addressing the danger of global warming and specifically increased funding to help them reduce greenhouse gas emissions. Finally, the amendment provided additional funding for programs that assist U.S. businesses willing to export clean energy technologies to developing nations………

Kennedy Opposed the Permanent Nuclear Waste Storage Facility at Yucca Mountain. Senator Kennedy is a strong opponent of the plan to create a permanent storage facility for nuclear waste at Yucca Mountain in Nevada. The potential for groundwater contamination from the site is yet to be determined, and the transfer of nuclear materials to Nevada from almost every state in the nation raises serious safety concerns. In addition, in March 2005, the Department of Energy admitted that falsified documents were used to ensure the credibility and safety of operations at Yucca Mountain. Until questions are resolved that will guarantee the health of both the public and the environment, it is irresponsible to approve a permanent storage site for nuclear waste.

New Doubts Over Nuclear Plant Safety

Startling Revelations About Three Mile Island Raise New Doubts Over Nuclear Plant Safety

Fooling with Disaster?

CounterPunch By SUE STURGIS April 2009

“…………………It was the single worst disaster ever to befall the U.S. nuclear power industry, and Thompson was hired as a health physics technician to go inside the plant and find out how dangerous the situation was. He spent 28 days monitoring radiation releases.

Today, his story about what he witnessed at Three Mile Island is being brought to the public in detail for the first time — and his version of what happened during that time, supported by a growing body of other scientific evidence, contradicts the official U.S. government story that the Three Mile Island accident posed no threat to the public.

Malaysia: where would we put nuclear waste?

Where do we store nuclear waste?

The Sun2 Surf , Malaysia 27 August 09

THE sun has been the main energy source for all life on the planet for billions of years. In Malaysia, we are blessed with sunlight. Yet, our government is pushing for nuclear energy as if it is a safe energy alternative to save our planet from the perils of climate change.

The government seems to be brushing aside the hazards related to nuclear power plants, as if they were issues that didn’t exist or could easily be remedied in the near future………………….

From what I have seen, there is no detailed information available to the public on Malaysia’s nuclear plans. Where will the reactors be located? What type of reactors will be used? Who will be selling us the uranium to run the reactors? How much will it all cost and who will pay for it?

What about the waste generated from the proposed nuclear power plants? Where and how will Malaysia dispose its nuclear waste which remains radioactive for thousands of years…………….

….we do know that nuclear energy will produce highly radioactive waste, even if it is in small amounts, every day a nuclear plant is running. We do know that this highly radioactive waste must be disposed of somewhere on our finite planet. We do know that we have no technology to make this waste safe.

And as more countries build nuclear power plants, more of this waste is dumped into our Earth, the planet that sustains our lives.

It is unforgivable that we, as governments and responsible adults, knowingly create such dangerous waste, so that we can have “modern conveniences” today, without a concern for tomorrow.

We are already leaving our children with our legacy of global warming, and choking pollution. And now we wish to leave this massive mess of nuclear waste and closed reactor sites to our grandchildren, leaving them with  the burden of trying to figure out how to solve the problem that we ourselves had no idea how to solve.

Indigenous people fight uranium mining in the Grand Canyon

Havasupai Gather to Halt Uranium Mining in the Grand Canyon

Brenda Norrell | August 26, 2009

Indigenous Havasupai people held a gathering to stop uranium mining in the Grand Canyon and protect ancestral Havasupai Territory, at the south rim of the Grand Canyon, in July of 2009. Indigenous peoples and activists came from the four directions, from Arizona Hopi land and from as far away as Hawaii, to participate with sacred songs and ceremonies.

For four days, Havasupai elders gathered on sacred Red Butte and listened to the legacy of uranium mining on Indian lands. They heard directly from the victims of the trail of death and cancer left behind by uranium mining corporations that were never held responsible on Pueblo and Navajo lands in the Southwest United States. They also listened to the promise of solidarity from the hundreds who gathered here to stand with them: Navajos from Big Mountain, Hualapai, Hopi, Kaibab Paiute, Paiute, Aztecs, and other American Indians from throughout the Americas.

The Havasupai Nation, with the Sierra Club, Center for Biological Diversity, and Grand Canyon Trust, sponsored the gathering to halt uranium mining on Red Butte, July 23-26, 2009. Supai elders gave testimony for official U.S. records in their Havasupai (Pai) language and in English. Supai traditional singers sang as a camp was established on this mesa where Toronto-based Denison Mines is threatening to reopen a uranium mine.

Recent congressional legislation protects the Grand Canyon from new mining claims, but does not deter mining under existing claims held by Denison and others………………

………. “In Numbers, There is Strength”

During the panel, Larry King, Navajo from Church Rock, NM, told the gathering how he worked for the United Nuclear Corporation from 1975 to 1983 as an underground mine surveyor. King said he has lived all his life in Church Rock and still raises his cattle on the land where he grew up. Now, a community activist, he said Navajos in the communities of Church Rock, Pinedale, Coyote Canyon, and Iyanbito, NM, have suffered greatly from uranium mining.

…………… Speaking of the corporations who have contaminated this region for decades, Pino said, “Why would they want to mine uranium in one of the natural wonders of the world like the Grand Canyon? If they will mine uranium here, they will mine uranium anywhere. They have no heart, they have no soul.”

Nuclear plants are water-guzzlers

Nuclear Plant Water use vs. Other Electricity Generation, 20 – 83% higher

Green Data Center Blog 24 August 09 Found this Australia study on “water requirements of nuclear power stations”

Here is the conclusion.
Per megawatt existing nuclear power stations use and consume more water than power stations using other fuel sources. Depending on the cooling technology utilised, the water requirements for a nuclear power station can vary between 20 to 83 per cent more than for other power stations.

If you are curious on how much water gets used in power generation you can look at the chart on this site:

Uranium price “flat”

Flat outlook for uranium spot prices

Australian Mining 26 August 2009 | by Michael Mills

Equity research company Resource Capital Research (RCR) said it is not expecting any significant changes to uranium spot prices in the near term.

The uranium spot price is currently trading at US$47.50 per pound, down 8% from the US$52 three months ago.

At the end of December 2008, the prices were US$52.50 per pound.

…………. The long term contract uranium price is US$65.00 per pound, which is down from US$70 per pound price at December 2008.

‘Fourth Generation’ Nuclear Power

ENERGY BULLETIN by Jim Green 25 August 09

‘Integral fast reactors’ and other ‘fourth generation’ nuclear power concepts have been gaining attention, in part because of comments by US climate scientist James Hansen.

…… There are two main problems……. nuclear power could at most make a modest contribution to climate change abatement, mainly because it is used almost exclusively for electricity generation which accounts for about one-quarter of global greenhouse emissions. Continue reading

The search for a nuclear graveyard

The search for a nuclear graveyard

radiation-warningThe Globe and Mail 26 August 09

40,000 metric tonnes of radioactive waste is stored at sites across Canada. Anna Mehler Paperny reports on the hunt for a permanent solution

Wanted: Friendly, open-minded community in need of jobs and a whack of infrastructure cash. Must be willing to play host to nuclear waste, perhaps until the end of time.More than six decades after joining the nuclear club, Canada is home to 22 nuclear reactors, 18 of them in operation, producing about 15 per cent of the country’s electricity. Canada also has 40,000 metric tonnes of radioactive waste – and counting.

For years, the issue of how to best dispose of this waste has plagued policy-makers, scientists and citizens. Suggestions have included shooting it into outer space or exporting it to the South Pole.

Now, Canada is preparing to get rid of its nuclear detritus once and for all – by burying it. Continue reading

‘Dirty timebomb’ ticking in Russian nuclear dump threatens Europe

Dirty timebomb’ ticking in Russian nuclear dump threatens Europe
Belfast Telegraph By Rachel Shields  25 August 09

20,000 discarded uranium fuel rods stored in the Arctic Circle are corroding. The possible result? Detonation of a massive radioactive bomb experts say could rival the 1986 Chernobyl disaster.

A decaying Russian nuclear dump inside the Arctic Circle is threatening to catch fire or explode, turning it into a “dirty bomb” that could impact the whole of northern Europe, including the British Isles.

Experts are warning that sea water and intense cold are corroding a storage facility at Andreeva Bay, on the Kola Peninsula near Murmansk. It contains more than 20,000 discarded fuel rods from nuclear submarines and some nuclear-powered icebreakers. A Norwegian environmental group, Bellona, says it has obtained a copy of a secret report by the Russian nuclear agency, Rosatom, which speaks of an “uncontrolled nuclear reaction”.

John Large, an independent British nuclear consultant who has visited the site, told The Independent on Sunday: “The nuclear rods are fixed to the roof and encased in metal to keep them apart and prevent any reactions from occurring. However, sea water has eroded them at their base, and they are falling to the floor of the tanks, where inches of saltwater have collected.

“This water will begin to corrode the rods, a reaction that releases hydrogen, a gas that is highly explosive and could be ignited by any spark. When another rod falls to the floor and generates such a spark, an enormous explosion could occur, scattering radioactive material for hundreds of kilometres.”

Mr Large, who was decorated by Russia’s President Vladimir Putin for his role in the salvage operation that retrieved nuclear material from the Kursk submarine in 2000, added: “This wouldn’t be a thermonuclear or atomic explosion, as in a bomb, but the outcome is just as bad. Remember Chernobyl? If you had the right weather conditions and wind pattern, this would mean a radioactive cloud drifting over the UK.”

The three storage tanks contain more than 32 tons of radioactive material. But the Kola Peninsula is littered with relics of Soviet nuclear facilities, housing more than 100 tons of nuclear waste – the largest concentration in the world.

Experts predict that a major explosion at Andreeva Bay could destroy all life in a 32-mile radius, including Murmansk and a sliver of Norway, whose border is only 28 miles away. But a much wider area of Norway, north-west Russia and Finland would be rendered uninhabitable for at least 20 years, and huge quantities of radioactive material would be dumped into the Barents Sea……………………

Another Chernobyl-type meltdown, this time in the Arctic, could have much more far-reaching effects. The worst case would be widespread fallout caused by rain in a densely populated area, causing untold social and economic disruption beyond the threat to life.

German customers are saying ‘No Thanks” to nuclear power

Many German customers are saying ‘No Thanks” to nuclear power
American German Business News Flavia Westerwelle 24 August 09

After the recent nuclear reactor shutdown at the Vattenfall Kruemmel nuclear plant near Hamburg, Germany, many German customers are preferring green energy.

On July 4th, 2009 the Kruemmel nuclear plant near Hamburg had been running for less than two weeks after a two year shutdown, when a sudden drop of voltage send shopping centers and traffic lights in Germany’s second largest city into an hour long blackout.After this incident the green energy company Lichtblick saw a dramatic jump in customers, with ca. 200 new customers per day.

This corresponds to a 70 % increase in customers for Lichtblick, a Hamburg-based company providing energy from renewable sources, with a mix of hydro, wind, solar and biomass power.It looks like the recent series of problems at nuclear plants combined with the issue of storing the nuclear waste has trigger a process of rethinking by many German customers eager to find a long term solution for Germany’s energy needs.

Nuclear Safety in India

Nuclear Safety in India

The Pakistani Spectator 25 August 09
India has not ratified the Nuclear Non-Proliferation Treaty. Yet, it has been exempted from nuclear restrictions imposed on non-signatories. The West has accorded preferential treatment to India ostensibly in consideration of her `immaculate’ nuclear safety record.

India’s Nuclear Power Corporation boisterously claims: “NPC engineers have shared their expertise internationally by participating in safety reviews and inspection of reactors in other countries conducted by the World Association of Nuclear Operators and the International Atomic Energy Agency. We are continuously updating our safety systems and procedures even at the cost of short-term economic benefit. Besides, all our plants are designed, constructed, commissioned, operated and maintained under strict supervision.

”What’s the real situation? It is true that there has not been an accident, leading to core meltdown and radiation exposures. But, the fact remains that several minor accidents have happened in the past. These accidents range from leaks of oil to complete loss of power in the reactors causing all safety systems to be disabled.

Let us look at some of the accidents. The accidents at Tarapur, Madras and Rajasthan plants were due to non-compliance with safety standards. According to the mandatory standards of operation, each reactor is supposed to have an independent emergency core-cooling system. But, in practice, one cooling system was being shared between two reactors.

The investigators were astonished to find that the reactors at Madras and Rajasthan had been operating without backup pumps to continue smooth operation. The plants had to be shut down as whenever the operating pumps were disabled by external factors such as fluctuations in the grid.A study by India’s Atomic Energy Regulatory Board documented over 130 extremely serious safety issues warranting urgent corrective measures in the Bhabha Atomic Research Centre, Indira Gandhi Centre for Atomic Research, Uranium Corporation of India, Heavy Water Board, Indian Rare Earths Limited and several other facilities.

The CIRUS reactor had an inherent problem of radiation leakage. Candu reactors suffered from heavy leakage of water. Dhruva reactor experienced fuel leakage, attributed to imperfect design architecture. Radioactive waste from the Tarapur Plant endangered lives of about 3,000 villagers living nearby……………….

Poor safety practices in India’s nuclear-power plants remain camouflaged under a cloak of secrecy. Authorities get alerted only when an accident occurs, necessitating a shut down. The NSG should have a second look at safety measures `observed’ in India’s power plants..  A cavalier approach to poor safety standards could result in a major accident, like Chernobyl or Three Mile Island.
