Chinese scientists have announced a breakthrough in nuclear fuel reprocessing technology that could end the country's energy supply problems, state media have said.

The technology developed by state-run China National Nuclear Corp will enable the re-use of irradiated nuclear fuel, China Central Television (CCTV) reported on Monday.

The technology developed and tested at the factory in the Gobi desert in the remote Gansu province will be able to boost the usage rate of uranium materials at nuclear plants by 60 folds.

"China's proven uranium sources will last only 50 to 70 years, but with the new technology [the] existing detected uranium resources can be used for 3,000 years," the CCTV report said.

The development is an important step forward in China's plans to increase the share of alternative power sources in its energy mix to reduce pollution and achieve energy security.

China has stepped up investment in nuclear power in an effort to slash carbon emissions and reduce the nation's heavy reliance on polluting coal, which presently accounts for 70 per cent of its power needs.

China, as well as France, the United Kingdom and Russia, actively support reprocessing as a means for the management of highly radioactive spent fuel and as a source of fissile material for future nuclear fuel supply.
But independent scientists argued that commercial application of nuclear fuel reprocessing has always been hindered by cost, technology, proliferation risk and safety challenges.

China has 171,400 tonnes of proven uranium resources spread mainly in eight provinces – Jiangxi, Guangdong, Hunan, Xinjiang, Inner Mongolia, Shaanxi, Liaoning and Yunnan.
Modest expansion
With a massive plans to push into nuclear power, China is making an effort to wean itself off coal, the dirtiest fossil fuel. It now has 12 working reactors with 10.15 gigawatt of total generating capacity.

Beijing has set an official target of 40 gigawatts of installed nuclear generating capacity by 2020, but the government indicated it could double the goal to about 80 gigawatts as faster expansion was one of the more feasible solutions for achieving emissions reduction goals.

As such, China will need to source more than 60 per cent of the uranium needed for its nuclear power plants from overseas by 2020, even if the country moves forward with a modest nuclear expansion plan, Chinese researchers say.

China, now the world's second-largest economy after surpassing Japan in 2010, aims to get 15 per cent of its power from renewable sources by 2020.

Nuclear fuel feat to solve uranium shortage

China has made a breakthrough in spent nuclear fuel reprocessing technology, which could greatly extend uranium's usage rate and potentially solve the problem of its supply shortage.

The technology, which was developed by the No 404 factory under the China National Nuclear Corp (CNNC), is able to boost the usage rate of uranium materials at nuclear plants by 60 times.

"With the new technology, China's existing detected uranium resources can be used for 3,000 years," according to China Central Television (CCTV) on Monday.

China, the world's second largest economy, has more than 170,000 tons of detected uranium resources.

"We're among the few countries that can implement the recycling of nuclear fuel As such, we, to some extent, lead the world in this field," Sun Qin, general manger of CNNC, China's largest nuclear generator, was quoted by CCTV as saying.

The nation has strived to extend the usage rate of the strategically important resource to meet growing demand. The country aims to increase its nuclear power capacity to 40 gigawatts (gW) by 2020 compared to just more than 9 gW of nuclear capacity at present.

China, as one of the world's largest energy consumers, now has 12 nuclear power plants in operation, with 25 reactors under construction.

Uranium demand in China is expected to reach 20,000 tons annually by 2020, according to figures from the World Nuclear Association. But China will be able to produce only 2,400 tons of uranium that year.

China used 1,300 to 1,600 tons of uranium in 2009, Reuters reported earlier.

The world has around 4.7 million metric tons of identified uranium minerals. Increasing usage has sparked concerns that uranium demand may eclipse supply soon.

Extending the usage of existing uranium will help China fulfill its target to cut greenhouse gas emissions per unit of GDP by 40 to 45 percent by 2020 from 2005 levels.

"China has invested heavily in uranium exploration know-how and recycling technology to meet the nation's burgeoning needs and increase the ratio of nuclear energy in the total energy consumption mix," said Lin Boqiang, director of the China Center for Energy Economics Research at Xiamen University.

He added that such technology, including the recycling of spent nuclear fuel, is still at a very early stage. If it can be put into practical use, then China can be self-sufficient, he said.

Nuclear power accounted for about 2.2 percent of China's electricity generation by the end of 2009. By contrast, of the 30 countries that have nuclear power generators, 16 had 25 percent of their total electricity produced by nuclear power.

Hackers may have a reputation for having dubious intentions, but there are those employed to hack into IT infrastructures to ensure their security. 

WITH high-profile cases such as that of Lin Mun Poo, the Malaysian who stole a massive quantity of financial account data by gaining access to the American Federal Reserve Bank, hackers have earned a rather notorious reputation.

However, Dell IT security manager Meling Mudin thinks that this mainstream definition of hacking is a narrow one.

Meling: A hacker is simply someone who likes to figure out how things work.
 

“It’s not just all about breaking into computer systems,” says Meling.

“For me, a hacker is simply someone who likes to figure out how things work, and proceeds to use that knowledge to invent creative new ways of using something.”

With almost 10 years of experience in the computer security field, the self-described ethical hacker professes a passion for tinkering around with technology.

“As an ethical hacker, I’m legally employed by a company to hack into their IT infrastructure to make sure that it is secure.

“The thrill I get from it is being able to understand how a particular software or system works. I don’t see the point of unlawfully cracking into someone else’s computer,” he says.

My job involves ...
... penetration testing of Dell’s internal and external information systems, which includes its databases, network routers and e-commerce websites. Basically I make sure that the company’s global IT infrastructure is secure – by hacking into it to detect any vulnerabilities.

Privacy is a particularly serious issue as scammers could potentially collect users’ personal data without their knowledge in order to gain access to bank accounts and credit card numbers. — File photo
 

The methodology for doing this is fairly routine. First, I gather all the information I need about the system and how it works, and then I look for possible vulnerabilities and try to exploit them. After that, I offer support in order to remedy any flaws in the system.

Hacking into a system is not just a matter of blindly going in and messing it up, because if I bring down a critical component in a company’s IT framework, it could potentially crash the whole thing and cost the company thousands.

So, I have to plan an attack so as to exploit any weaknesses without compromising the entire system.
Another thing my department does is a quarterly review to make sure that Dell’s system and security policy comply with the industry standards.

My morning starts with ...
... checking e-mails and going through my Google Reader to check out the latest updates in security threats and systems.

The rest of the day is usually just getting on with my work or updating clients on my progress.

As more people become increasingly reliant on technology for everyday tasks, there is a greater need for experts to ensure computer and network security. — AP file photo
 

Working at Dell, I only need to go into the office once a week to attend meetings, brief clients or have a one-on-one session with my supervisor.

The rest of the time, I’m free to do my work wherever I want, as long as deadlines are met. Typically, I would be working on multiple projects, and each one can take between three to 10 days to execute.

However, this varies from company to company. If you’re working at a consultancy firm for instance, you probably would have to go on-site to work at the client’s request.

To qualify, you need...

... a degree in information technology, computer science, or even engineering.

These days, there are numerous professional certifications to pursue if you wish to specialise in a certain area of IT security. You could for instance be a malware analyst or a forensic investigator.

But getting certified can be an expensive affair as these courses cost thousands. If you can’t afford it, it’s better to just build up experience in the field. The security industry in Malaysia is still quite small, so your peers will know how good you are as long as you take the initiative to prove yourself. As long as you are reputable, it doesn’t matter if you’re certified or not.

The best person for the job ...
... is someone who is passionate and interested in the world of computing.

You also need a sense of curiosity about how things work, and have the eagerness to keep learning.
Since you need to translate a lot of technical jargon into plain language for your clients, having good communication skills is equally important.

I love my job because ...
... of the continuous learning experience the field provides. In IT security, there are always new threats to circumvent and new methodologies to explore.

I enjoy getting into the mechanics of the latest technology and see how we can improve security systems.
What I dislike most...

... is nothing really! I honestly have no complaints, because it’s all part and parcel of my line of work.
Although a task like writing reports can get tedious at times, it is an important process in order to get the client to understand what it is that I have just fixed.

Prospects for the future...
... are very good. There will always be a demand for security professionals, especially as we get more and more reliant on technology for everyday tasks.

Privacy is a particularly serious issue as scammers could potentially collect your personal data without your knowledge in order to gain access to bank accounts, credit card numbers and so on.

A millionaire by 30?
 It is possible, as long as you plan your career. If you have the right attitude and enough experience, I certainly think that you can make a fair amount of money.

The world: What lies ahead in 2011?

By JOSEPH STIGLITZ

The answer is bleak, with little upside potential and a lot of downside risk.


Tweet

THE global economy ends 2010 more divided than it was at the beginning of the year.

On one side, emerging-market countries like India, China, and the South-East Asian economies, are experiencing robust growth. On the other side, Europe and the United States face stagnation indeed, a Japanese-style malaise and stubbornly high unemployment. The problem in the advanced countries is not a jobless recovery, but an anaemic recovery or worse, the possibility of a double-dip recession.

This two-track world poses some unusual risks. While Asia's economic output is too small to pull up growth in the rest of the world, it may be enough to push up commodity prices.

Meanwhile, US efforts to stimulate its economy through the Federal Reserve's policy of “quantitative easing” may backfire. After all, in globalised financial markets, money looks for the best prospects around the world, and these prospects are in Asia, not the United States. So the money won't go where it's needed, and much of it will wind up where it's not wanted causing further increases in asset and commodity prices, especially in emerging markets.

Given the high levels of excess capacity and unemployment in Europe and America, quantitative easing is unlikely to trigger a bout of inflation. It could, however, increase anxieties about future inflation, leading to higher long-term interest rates precisely the opposite of the Fed's goal.

This is not the only, or even the most important, downside risk facing the global economy. The gravest threat comes from the wave of austerity sweeping the world, as governments, particularly in Europe, confront the large deficits brought on by the Great Recession, and as anxieties about some countries' ability to meet their debt payments contributes to financial market instability.

The outcome of premature fiscal consolidation is all but foretold: growth will slow, tax revenues will diminish, and the reduction in deficits will be disappointing. And, in our globally integrated world, the slowdown in Europe will exacerbate the slowdown in the United States, and vice versa.
With the United States able to borrow at record-low interest rates, and with the promise of high returns on public investments after a decade of neglect, it is clear what it should do.

A large-scale public investment programme would stimulate employment in the short term, and growth in the long term, leading in the end to a lower national debt. But financial markets demonstrated their shortsightedness in the years preceding the crisis, and are doing so once again, by applying pressure for spending cuts, even if that implies reducing badly needed public investments.

Moreover, political gridlock will ensure that little is done about the other festering problems confronting the American economy: mortgage foreclosures are likely to continue unabated (legal complications aside); small and medium-sized enterprises are likely to continue to be starved of funds; and the small and medium-sized banks that traditionally provide them with credit are likely to continue to struggle to survive.

In Europe, meanwhile, matters are unlikely to be any better. Europe has finally managed to come to the rescue of Greece and Ireland. In the run up to the crisis, both were governed by right-wing governments marked by crony capitalism or worse, demonstrating once again that free-market economics didn't work in Europe any better than it did in the United States.

In Greece, as in the United States, a new government was left to clean up the mess. The Irish government that encouraged reckless bank lending and the creation of a property bubble was, perhaps not surprisingly, no more adept in managing the economy after the crisis that it was before.

Politics aside, property bubbles leave in their wake a legacy of debt and excess capacity in real estate that is not easily rectified especially when politically connected banks resist restructuring mortgages.

To me, attempting to discern the economic prospects for 2011 is not a particularly interesting question: the answer is bleak, with little upside potential and a lot of downside risk. More importantly, how long will it take Europe and America to recover, and can Asia's seemingly export-dependent economies continue to grow if their historical markets languish?

My best bet is that these countries will maintain rapid growth as they shift their economic focus to their vast and untapped domestic markets. This will require considerable restructuring of their economies, but China and India are both dynamic, and proved their resilience in their response to the Great Recession.

I am not so bullish on Europe and America. In both cases, the underlying problem is insufficient aggregate demand. The ultimate irony is that there are simultaneously excess capacity and vast unmet needs and policies that could restore growth by using the former to address the latter.


Both the United States and Europe, for instance, must retrofit their economies to address the challenges of global warming. There are feasible policies that would work within long-term budget constraints.

The problem is politics: in the United States, the Republican Party would rather see President Barack Obama fail than the economy succeed. In Europe, 27 countries with different interests and perspectives are pulling in different directions, without enough solidarity to compensate. The bailout packages are, in this light, impressive achievements.

In both Europe and America, the free-market ideology that allowed asset bubbles to grow unfettered markets always know best, so government must not intervene now ties policymakers' hands in designing effective responses to the crisis. One might have thought that the crisis itself would undermine confidence in that ideology. Instead, it has resurfaced to drag governments and economies down the sinkhole of austerity.

If politics is the problem in Europe and America, only political changes are likely to restore them to growth. Or else they can wait until the overhang of excess capacity diminishes, capital goods become obsolete, and the economy's internal restorative forces work their gradual magic. Either way, victory is not around the corner. Project Syndicate, 2010

Dream house no more?

By DANIEL GROS

Tweet
 
The dream of homeownership is very much alive in the emerging world.

THE financial crisis that began in 2007 had its roots in excesses in the housing market that remained unresolved in 2010 and that will continue to roil economies in 2011 and beyond.

Everybody now knows about America's dodgy “subprime” mortgages (the term says it all). But it is all too easy to forget that the development of this market was initially welcomed, because it enabled even people who would not normally qualify for a mortgage loan to aspire to homeownership. Subprime mortgages made the American dream come true.

Of course, billions of others around the world share the same dream. But the way housing finance is organised differs enormously from country to country, and these differences explain the recent global imbalances and financial crashes.

In developed economies, construction can add only a relatively small amount each year to the existing stock of housing. With populations stagnating (or declining in many parts of Europe and Japan), the existing stock of housing is exchanged among different parts of the population, and typically bequeathed from old to young.

The situation is different in emerging economies, where the quantity and quality of the existing stock of housing is woefully inadequate. Moreover, most of the existing housing tends to be in rural areas, whereas most of the jobs are in the cities. This is why urbanisation means a huge building boom in emerging economies. China, as usual, is the most extreme example, now accounting for more than one-half of global cement consumption.

The dream of homeownership is thus very much alive and is a powerful economic force in the emerging world. But mortgage markets remain underdeveloped in most emerging economies. This means that young Chinese couples will first have to save a large part of their income as a downpayment for their dream house (typically an apartment in a high-rise).

The absence of “no money down” mortgages might be more important than Confucian ethics in explaining China's high savings rate. One sure way to reduce the savings rate in China would be to develop an American-style mortgage market there.

The Chinese and others should, however, bear in mind that an increase in housing prices does not make a country richer. Of course, every homeowner will feel richer if his property's price goes up. But if the price of all housing goes up, the country as a whole is no better off; after all, people have to live somewhere, so, other things being equal, cashing in on higher house prices would merely mean paying more for one's next home.

Housing booms thus create only an illusion of wealth, though it is compelling enough to induce excessive consumption, as occurred in the United States over the last decade.

Conversely, a crash in house prices does not destroy any real wealth (the houses still stand). On the contrary, a crash makes the dream of ownership more affordable, which benefits first-time buyers typically the young and less well-off.

But, from an economic point of view, the share of homeowners versus tenants is not very important. If the rental market is well developed (as in, say, Germany), most families might elect not to own. But Germans still own indirectly the houses they live in through their investments with life-insurance companies and savings societies, which own and manage a large proportion of the country's housing estates.

By contrast, from an economic point of view, many American households really rent their homes from the Chinese government. They might be proud homeowners on paper, but their mortgage was probably underwritten by quasi-governmental institutions like Fannie Mae and Freddie Mac, which in turn rely heavily on capital from China for their own refinancing.

The real danger arises when everyone is convinced that investing in real estate is the best way to secure one's own future because house prices can only go up. This induces lenders to provide not only NINJA (no income, no job, no assets) mortgages, but also generous loans to real-estate developers to build ever larger mansions and housing estates.

As long as a boom lasts, everybody benefits. But when the bubble bursts, the NINJAs cannot service their debt and builders go into bankruptcy. Lenders find that the collateral (half-finished or empty houses) is worth almost nothing, resulting in huge losses in the banking system (as the United States found out in 2008).

In extreme cases, as in Ireland (one hopes not in Spain), the need to save the banking system can bankrupt an entire country.

Housing booms can last a long time, typically more than a decade. The downside is that housing busts last equally long, because houses are such a durable good. Once too many houses have been built, the existing overhang depresses the market for a very long time, and unemployed construction workers are usually unable to find jobs elsewhere.

The last decade saw the peak of an unprecedented housing boom in most of the rich world. The bust, with its banking problems and unemployment, is likely to last for most of the coming decade, depressing growth in all those countries which looked so strong in 2008.

By contrast, the emerging economies have barely started their own boom, which is underpinned by the spillover of liquidity from the United States. The emerging world's boom might well stretch over the entire next decade, as hundreds of millions of homes are built.

The next bust can be avoided only if emerging markets manage the dream of homeownership better than the United States and Europe. Project Syndicate, 2010

Singaporeans least , Malaysia more among, likely to worry about housing: survey

Tweet

Singapore has emerged last in the latest Gallup poll of 128 countries on unaffordable housing, local media reported Friday.

The global survey by polling agency Gallup covered 1,000 or more respondents in each country, and only 1 percent of Singaporeans said there had been times over the past 12 months when they did not have enough money to provide adequate shelter for themselves and their families.

Denmark was the second last at 2 percent.

In contrast, Azebaijan, Liberia and Chad, which were in the top three places, had results of 76, 53 and 51 percent, respectively.

Among other countries in Asia, Malaysia had 14 percent of its population worrying about affordable housing and Japan had 9 percent.

Gallup had conducted the poll by telephone or face-to-face interviews over last year and this year.

Singapore has been known for its policy of relying on government efforts to provide affordable housing for its population. About 80 percent of the population in the small open economy live in homes developed by the government.
