China developing outdated, cheap, less safe nuclear reactors – Wikileaks

The US embassy and Westinghouse may have wanted to play up the risks to improve the strength of their own bids, but safety concerns are also expressed within China. This year, Prof He Zuoxiu, who helped to develop China’s first atomic bomb, claimed plans to ramp up production of nuclear energy twentyfold by 2030 could be as disastrous as the “Great Leap Forward” – Mao Zedong’s disastrous attempt to jump-start industrial development in the late 1950s.

WikiLeaks cables reveal fears over China’s nuclear safety, Cables highlight US lobbying and say that cheap, out-of-date technology is ‘vastly increasing’ risk of nuclear accident,, Asia environment correspondent, guardian.co.uk,   25 August 2011 

China has “vastly increased” the risk of a nuclear accident by opting for cheap technology that will be 100 years old by the time dozens of its reactors reach the end of their lifespans, according to diplomatic cables from the US embassy in Beijing. 

The warning comes weeks after the government in Beijing resumed its ambitious nuclear expansion programme, that was temporarily halted for safety inspections in the wake of the meltdown of three reactors in Fukushima, Japan.

Cables released this week by WikiLeaks highlight the secrecy of the bidding process for power plant contracts, the influence of government lobbying, and potential weaknesses in the management and regulatory oversight of China’s fast-expanding nuclear sector.

In August, 2008, the embassy noted that China was in the process of building 50 to 60 new nuclear plants by 2020. This target – which has since increased – was a huge business opportunity. To keep up with the French and Russians, the cable urged continuous high-level advocacy on behalf of the US company Westinghouse to push its AP-1000 reactor.

This is crucial, according to the cable dated 29 August 2008 from the American Embassy in Beijing, because “all reactor purchases to date have been largely the result of internal high level political decisions absent any open process.”

For the US embassy, a bigger concern was that China seemed more interested in building its own reactors – the CPR-1000 – based on old Westinghouse technology, at Daya Bay and Ling Ao.

As the CPR-1000 increases market share, China is assuring that rather than building a fleet of state-of-the-art reactors, they will be burdened with technology that by the end of its lifetime will be 100 years old,” reads another cable dated 7 August 2008….

The cable suggests this was a dangerous choice: “By bypassing the passive safety technology of the AP1000, which, according to Westinghouse, is 100 times safer than the CPR-1000, China is vastly increasing the aggregate risk of its nuclear power fleet. ”

“Passive safety technology” ensures that a reactor will automatically shut down in the event of a disaster without human intervention. Plants without this feature are considered less safe as they rely on human intervention which can be difficult to provide in a crisis situation.

China says it has updated and improved the technology on which the CPR-1000 is based, but the government recognises that it is less safe than newer models. …..

Writing in the Science Times, He asked: “Are we really ready for this kind of giddy speed [of nuclear power development]? I think not – we’re seriously underprepared, especially on the safety front.”….http://www.guardian.co.uk/environment/2011/aug/25/wikileaks-fears-china-nuclear-
