QINGDAO Wholesale Wisconsin Badgers Jerseys , June 23 (Xinhua) -- Chinese submersible Jiaolong will begin a global scientific expedition by about 2020, scientists said Friday.
The submersible, named after a mythical dragon, returned to the national deep sea center in eastern China's Qingdao Friday following a four-month deep sea tour, the country's 38th oceanic scientific expedition.
Before the 2020 expedition, China will have the submersible upgraded and finish the building of a new mothership.
The 38th expedition started in February and its completion marks the end of the submersible's five-year trial phase.
The Jiaolong is capable of diving in virtually all global seas to a depth less than 7,000 meters Wholesale West Virginia Mountaineers Jerseys , scientists said.
The submersible made 30 dives during the latest expedition and descended to nearly 6,700 meters in the Yap Trench in the west Pacific, close to its record depth of 7,062 meters in 2012.
Scientists gained precious samples and data in this expedition, including rocks, large marine life, two lion fish and two unknown species.
They also reached a better understanding of deep sea hydrothermal movement in the Indian Ocean Wholesale Usc Trojans Jerseys , and conducted surveys in the South China Sea that will help multi-metal nodule mining tests.

ON a train to Shanghai, I casually asked about 10 fellow passengers what would they do if a nuclear reactor were proposed to be built close to their homes.
To a person, they replied that they would never live near a nuclear facility.
That’s the kind of public skepticism China faces as it plans to increase its nuclear power facilities to meet growing electricity demand without expanding the use of air-polluting fossil fuels.
As of June, China had 36 nuclear reactors in operation and 21 under construction. The National Development and Reform Commission has said it wants nuclear power to account for 6 percent of the nation’s electricity generation by 2020 Wholesale Ucla Bruins Jerseys , up from about 3 percent in 2015. That compares with 10 percent in the US and 74 percent in France.
By 2026, China will overtake the US as the world’s biggest generator of nuclear power, according to UK-based BMI Research.
China’s ambitions are in direct contrast to policies in other countries. The Fukushima nuclear disaster in Japan in 2011 has changed minds about risk versus power sources. As of last year, Italy closed all its nuclear power stations, and Belgium, Germany, Spain Wholesale Texas Longhorns Jerseys , Switzerland, the Netherlands and Sweden are phasing out plans.
China begs to differ. Nuclear power, according to Zheng Mingguang, president of the Shanghai Nuclear Engineering Research and Design Institute, “is a way to enhance energy safety and meet growing electricity demand.”
China’s nuclear power capacity is concentrated along its coastline, where large urban cities have had to rely on electricity transported from inland areas of the west and north.
In 2014, China set a target of generating 20 percent of its energy needs from non-fossil fuels. The nation has been developing hydropower Wholesale South Carolina Gamecocks Jerseys , and wind and solar energy technologies to ease dependence on coal and oil.
Hydro, solar and wind power, to one degree or another, rely on the vagaries of nature to provide peak generation. Nuclear power provides a predictable and more constant supply of electricity.
Zhejiang Province, which abuts Shanghai, is a hub of nuclear power generation, with nine operating reactors and another two under construction.
One of the Zhejiang plants Wholesale Penn State Nittany Lions Jerseys , due to begin operation in the fourth quarter, is named AP1000. It represents “third-generation” nuclear technology. The name refers to the “advanced passive system,” which contains automated water cooling loops to avoid explosions.
Still, public anxiety about nuclear power remains high, six years after the Fukushima disaster shocked the world.
Last week, at the 25th International Conference on Nuclear Engineering in Shanghai, the emphasis was on safety in the development of nuclear technology.
Gu Shenjie Wholesale Oregon Ducks Jerseys , deputy chief engineer at the nuclear institute, said the nation is keen to use and upgrade nuclear technology, “especially in the improvement of safety and quality.”
Unlike the second-generation of technology, as exemplified in the Fukushima reactors, the third-generation includes advancements like strengthening containment vessels to avoid nuclear leaks and adding automated cooling systems to avert explosions.
“It means living close to nuclear plant is far safer than taking an airline flight,” said Francois Morin, director for China at the World Nuclear Association.
Fear of nuclear power Wholesale Oklahoma State Cowboys Jerseys , he said, is overly magnified in people’s minds.
More than 200 institutes and companies have been deployed in China to help localize and improve the third-generation nuclear technology since China bought it from US-based Westinghouse in 2007. Nuclear power development involves more than 20,000 researchers.
“The operation of AP1000 reactors in Sanmen in Zhejiang Province, and Haiyang in Shandong Province was delayed four years due to problems found in key components,” the nuclear institute’s Zheng said.
“Only with reliable technologies can we run the reactors and reassure the public,” he said.
