* Indian Supreme Court gives nod to Kudankulam nuclear plant, says it is safe

Thank goodness.  India needs all the power it can generate.

Times of India: “In a relief for the Centre and the Tamil Nadu government, the Supreme Court on Monday approved the commissioning of the controversial Kudankulam nuclear plant.

Kudankulam plant is safe and secure and it is necessary for larger public interest and economic growth of the country, the SC said.

“Nuclear power plants are needed in the country for the present and future generations,” observed the apex bench.

The apex court said that the Kudankulam N-plant has been set up by the government for the welfare of the people.

A bench of justices K S Radhakrishnan and Dipak Misra, which had reserved the verdict following marathon arguments in the last three months, delivered the judgement.

A batch of petitions was filed by anti-nuclear activists challenging the project on the ground that safety measures recommended for the plant by an expert body have not been put in place.

They also raised various questions pertaining to the disposal of nuclear waste, the plant’s impact on the environment and the safety of people living nearby, besides other issues linked to the controversial plant.

The Centre, Tamil Nadu government and Nuclear Power Corporation of India Ltd, which operates the plant, had refuted all the allegations on safety and security aspects.

They had submitted that the plant is completely safe and can withstand any kind of natural disaster and external terrorist attack.”

* Plans to Harness China’s Nu River Threaten a Region

NY Times: “From its crystalline beginnings as a rivulet seeping from a glacier on the Tibetan Himalayas to its broad, muddy amble through the jungles of Myanmar, the Nu River is one of Asia’s wildest waterways, its 1,700-mile course unimpeded as it rolls toward the Andaman Sea.

But the Nu’s days as one of the region’s last free-flowing rivers are dwindling. The Chinese government stunned environmentalists this year by reviving plans to build a series of hydropower dams on the upper reaches of the Nu, the heart of a Unesco World Heritage site in China’s southwest Yunnan Province that ranks among the world’s most ecologically diverse and fragile places.

Critics say the project will force the relocation of tens of thousands of ethnic minorities in the highlands of Yunnan and destroy the spawning grounds for a score of endangered fish species. Geologists warn that constructing the dams in a seismically active region could threaten those living downstream. Next month, Unesco is scheduled to discuss whether to include the area on its list of endangered places.

Among the biggest losers could be the millions of farmers and fishermen across the border in Myanmar and Thailand who depend on the Salween, as the river is called in Southeast Asia, for their sustenance. “We’re talking about a cascade of dams that will fundamentally alter the ecosystems and resources for downstream communities that depend on the river,” said Katy Yan, China program coordinator at International Rivers, an advocacy group.

Suspended in 2004 by Wen Jiabao, then the prime minister, and officially resuscitated shortly before his retirement in March, the project is increasing long-simmering regional tensions over Beijing’s plans to dam or divert a number of rivers that flow from China to other thirsty nations in its quest to bolster economic growth and reduce the country’s dependency on coal.

According to its latest energy plan, the government aims to begin construction on about three dozen hydroelectric projects across the country, which together will have more than twice the hydropower capacity of the United States.

* China moves cautiously ahead on nuclear energy

Bulletin of the Atomic Scientists: “From 2005 to 2011, China rapidly developed its nuclear power capacity. In 2010 alone, it began operations at two new reactors and broke ground on 10 more, accounting for more than 60 percent of new reactor construction worldwide and making the Chinese nuclear industry by far the fastest-growing in the world. By the end of 2010, China had 14 nuclear reactors in operation with a total capacity of about 11 gigawatts electric, or GWe. That was still a relatively small amount — in contrast, the United States had 104 commercial reactors with a total capacity of about 100 GWe in 2010 — but China was pursuing ambitious plans to rapidly expand.

China Nuclear Energy

Then came the tsunami and earthquake that led to Japan’s Fukushima Daiichi meltdown in March 2011, the world’s worst nuclear accident since the Chernobyl disaster in 1986. After Fukushima, China changed course dramatically, slowing the pace of nuclear development to focus on safety. The slower pace is reassuring, but to really be a leader on nuclear safety, China should speed up the adoption of new laws on nuclear energy and enhance the independence and authority of nuclear safety regulators.

Putting the Brakes On. According to a government plan issued in 2007, China planned to install a total nuclear capacity of 40 GWe by 2020, which would account for about 3 percent of electricity generation nationwide. Many officials and experts expected that the number would actually increase further, to more than 80 GWe.

In its initial, March 2011 reaction to Fukushima, though, China’s State Council, the nation’s governing body, decided to suspend approval of new nuclear power stations, conduct comprehensive safety inspections of existing plants, and review all nuclear projects including those under construction. In October 2012, after concluding the inspections and reviews, the State Council issued a new plan that represents a serious and cautious reevaluation of safety issues and the pace of development. Called the Medium- and Long-term Nuclear Power Development Plan (2011-2020), its proposals include:

A return to normal construction at a controlled and orderly pace.

Permission for a limited number of new nuclear power reactors to be built in coastal sites that have been comprehensively evaluated.

A ban on new inland nuclear power projects, because the government fears a shortage of cooling water should accidents occur at such plants.

A requirement that all new projects meet the safety standards of the world’s most advanced nuclear reactors, known as third generation or Gen III reactors. Compared to earlier technology, these new designs incorporate improved fuel technology, superior thermal efficiency, passive rather than active safety systems, and standardized designs aimed at reducing maintenance and capital costs.

Based on the new plan, China will only approve a few new reactor construction projects before 2016. China now expects to grow its total nuclear capacity to 58 GWe by 2020, rather than the more than 80 GWe previously expected.

The government resumed approval of new nuclear power projects in December 2012, just as the new plan was issued. Several inland nuclear power projects where significant preparation work had already begun will be suspended, with some of their equipment likely transferred to coastal sites. While the pace of Chinese nuclear development will slow in the near term, the country’s long-term goals haven’t changed significantly. China continues to emphasize nuclear power as a crucial part of its energy mix. A government white paper issued in October 2012 observed that “as nuclear power is a high-quality, clean, and efficient modern energy resource, its development is of great importance for optimizing the nation’s energy structure and ensuring national energy security.” The white paper put China’s nuclear energy target at 40 GWe by 2015.”

* China’s Shale-Gas Potential and Peril

Businessweek: “In China there’s a giddy feeling that the next energy gold rush is about to begin. Beneath the mountains of Sichuan province, the deserts of Xinjiang, and elsewhere, China contains twice the shale- gas reserves as the U.S., says the U.S. Energy Information Administration. China’s national planners enthusiastically back boosting natural gas production, which accounts for just 4 percent of the country’s total energy mix now. The government wants to double that share by 2015. “There’s a lot of exuberance,” says Zhou Xizhou, who leads the research firm IHS Cera’s China Energy practice. “In Beijing, if you work in energy, you probably receive a shale-gas conference notice every week.”

The impact of a shale-gas boom in China will be enormous, with the potential benefits and likely environmental costs perhaps even greater than in the U.S. So far, though, the output in China has been a trickle because of the challenging geography and the monopolistic structure of China’s oil and gas sector. While about 200,000 of the horizontal wells used in fracking have been drilled in the U.S., China has about 60. China has 1,275 trillion cubic feet of shale-gas reserves, compared with 637 trillion cubic feet for the U.S.

The U.S. shale-gas revolution was launched largely on the flatlands of Texas, North Dakota, Pennsylvania, and other accessible areas. In China’s mountainous Sichuan basin, “the formations seem to be more faulted and folded, which makes it more difficult and less economic to drill long horizontal well bores,” says Briana Mordick, an Oil & Gas Science Fellow at the Natural Resources Defense Council and formerly a geologist at Anadarko Petroleum.

Sometimes the Chinese must cut new mountainside roads to move trucks and equipment to remote sites. With higher upfront costs, “it will be significantly more challenging in China to make the wells pay for themselves,” Mordick says. “The technical learning curve is very steep. What works in one place may not work in another.“

The inflexible structure of China’s state-controlled oil and gas industry hampers efforts to exploit reserves. “In the U.S., it was not the oil and gas majors that started the shale boom” but rather small wildcat operators “willing to accept a high-risk, high-reward proposition,” says Melanie Hart, an analyst on energy policy and China at the Center for American Progress in Washington. “In a market system, you can have many small and large players all specializing in different pieces of the process.””
