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.
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.
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. |
