Phase II of Ling Ao Nuclear Power Plant goes online

Please, Log in or Register to view URLs content!



The No. 1 unit of Phase II of the Ling Ao Nuclear Power Plant was connected to the grid on Sept. 20 and started commercial operation recently, Sichuan Daily reported on Friday.

It is China's first home-made nuclear power unit based on the CPR1000, which is improved Chinese pressurized water reactor technology constructed by Sichuan-based Dongfang Turbine Co., Ltd.

The No. 1 unit is the largest one, both in terms of capacity and size, and it is the most advanced in technology, efficiency and automation requirements, Dongfang Chief Engineer Wang Weimin said.

Chinese nuclear power plants have relied on imports for rotors and core components in the past, but during the construction of the Ling Ao Nuclear Power Plant Phase II all the rotors have been developed and made independently by China.

Now that the No.1 unit is running, China's installed nuclear power capacity has exceeded 900 million kilowatts, marking a new high point in the development of China's energy industry.

"China's Chang'e-2 to scout moon in latter half of 2010 for lunar rover landing sites
14:49, September 01, 2010

China's second lunar probe, Chang'e-2, will be launched in the latter half of the year, said Sun Jiadong, a top space scientist and the winner of China's State Supreme Science and Technology Award, on Tuesday.

Sun said that Chang'e-2, which is named after the Chinese goddess of the moon, will photograph landing sites for the country's lunar lander and rover.

Sun also said that China's manned lunar landing project is in progress now. He said that the manned lunar landing is an important exploration for all human beings and China cannot miss it.

The timing of China's manned lunar landing is also being discussed now, he said.

Sun is one of the major scientists planning China's lunar exploration and was nominated as the chief designer of the first stage of China's lunar orbiter project.

He said that China's lunar exploration program mission will progress in three stages. Chang'e-1 ended its 16-month mission on March 1, 2009 when it [intentionally] impacted the Moon's surface; marking the completion of the first stage. Chang'e-2 will make preparations for the second stage that will send China's first lunar lander and rover to the Moon to perform close observations on the Moon surface. During the third stage, China will send a spacecraft to the Moon to collect samples and return.

"Launch of Chang'e-2 Satellite Eyed in Early Oct.
2010-09-25 22:10:00 CRIENGLISH.com Web Editor: Zhang Xu

Astronauts and experts from China's manned spaceflight project told students in east China's Shandong Province on Wednesday that the Chang'e-2 lunar probe is expected to be launched in early October, Qilu Evening News reports.

Six Chinese astronauts participated in an interactive event with local youths in Tengzhou, Zaozhuang, including Yang Liwei, Fei Junlong, Nie Haisheng, Zhai Zhigang, Liu Boming, and Jing Haipeng. All of them have previously flown on manned space flights.

The Chang'e-2 satellite has been sent to the Xichang Satellite Launch Center and will be ready by the upcoming launch date; the newspaper learned from the event on September 22nd.

The report tentatively gave the launch date as October 1st, but did not elaborate.

The main tasks of the Chang'e-2 are to perform tests of the key technologies that will be used for the Chang'e-3's lunar landing and record images of the Chang'e-3's landing area with a high-resolution stereo camera.

The experts said the Chang'e-2 will reach lunar orbit within 120 hours; much faster than the Chang'e-1 which changed its orbital direction four times and circled the Earth for seven days.

Moreover, the Chang'e-2 will orbit 100 kilometers closer to the Moon than its predecessor which was 200 kilometers from the Moon's surface.

The Chang'e-1 was launched in October 2007 as part of China's ambitious three-stage moon mission. Named after a mythical Chinese goddess who flew to the Moon, the Chang'e-1 was a milestone in the Chinese space program."

Factually, if only whining can help improve HSR tech, those countries in the report would have looked to Germany and Japan for HSR instead of China.

:rofl:

How do you know they had'nt, but decided to go with what met their budget better. While Saudia Arabia, where money wasn't a problem, opted for a Siemens/ China co production.

Factually it would have probably taken China more than 6yrs to develop her indegenous HSR technology to a exportable standard if it hadnt been for tech transfer from Germany and Japan. A point I had spent many an hour arguing the point, with fellow train travellers last month, while riding around on her HSR last month. But having said that the train rides were still impressive though.

Definitely -- I think that was a very wise move for China. Learn from foreign companies and improve their own indigenous products (legally of course, through tech transfer deals).

The article gives a half truth saying China developed it in 6 years; but these details are probably just worded differently to cater for a more pro China audience. It's all really superficial; the real gains will be in economic development and growth and not bragging rights.

Quite true, although Chinas rapid break through into the HSR export market, may make foreign concerns a little more hesitant about tech transfer.

And how do you they had ? You're part of the decision making process ? :D
And you obviously know little about business. Budgeting is not just some trivial matter you can brush aside.
Fanboys like you usually talk only about some 'magical' technologies. But if you cannot meet the budget of the markets, it only means your technologies is not so 'magical' after all. LOL

Actually it was because Siemen realized that they wouldn't be competitive enough to win the bidding by going it alone. So they decided to join the Chinese!

Qinghai-Tibet Railway to Xigaze

Please, Log in or Register to view URLs content!


LHASA - China started on Sunday to build an extension to the world's highest rail link, the Qinghai-Tibet Railway, to Xigaze, the second largest city in the southwestern Tibet autonomous region.

The 253-km extension from Tibet's capital Lhasa to Xigaze will pass through five counties and over the 90-km long Yarlung Zangbo Grand Canyon.

The construction will take about four years.

It is the first extension of the Qinghai-Tibet Railway that opened in July 2006.

The Lhasa-Xigaze section of the railway, with a budget of 13.3 billion yuan ($1.95 billion), has a designed transport capacity of 8.3 million tons annually.

Minister of Railways Liu Zhijun said the extension is a key project in China's long and medium-term railway network expansion and will speed up Tibet's social and economic development.

It will play a vital role in boosting tourism and promoting the rational use of resources along the line, he said.

Xigaze, with a history of more than 600 years, is Tibet's second largest city and the traditional seat of the Panchen Lamas.

Xigaze City is the administrative center of the Tibetan prefecture of the same name, a 182,000 square km area that neighbors India, Nepal and Bhutan. It is also famous for Qomolangma (known as Mount Everest in the West), which rises up from it.

Duh...... Common sense dude.... Anyone who had a brain would realise one should consider all the options in business, and many of those projects have been well described/publicised eg Arnies recent HSR tour around the compeititors.

Its not that the other countries products are unrealistic, higher production costs, and very possibly better quality, adds to the cost

Having trains traveling along atspeeds up to 800KPH is not that far fetched for the future. China, Europe North Amarica are ideal continents for very long distance high speed rail of some sort. and are you suggesting Siemens sucked the Chinese in with the Maglev then?. Too get to speeds of 600-800kph to match airliner cruising speeds "Maglev" might be the only way. As Martin said earlier overheating of the wheels at extreme speeds is a problem.

Considering products from China were not known for their quality or reliability in the past,etc etc, while German stuff which in this case Siemens is, it then becomes a bit of a calculated gamble ............Chinas 6yrs experience which needed foreign help, .compared to decades for the others............... :coffee:
