Chinese dredging vessels are purportedly seen in the waters around Mischief Reef in the disputed Spratly Islands in the South China Sea in this still image from video taken by a P-8A Poseidon surveillance aircraft provided by the United States Navy May 21, 2015.
A top mainland research institute is developing the world’s smallest ­nuclear power plant, which could fit inside a shipping container and might be installed on an island in the disputed South China Sea within five years.

Researchers are carrying out intensive work on the unit – dubbed the hedianbao, or “portable nuclear battery pack”.

Although the small, lead-cooled reactor could be placed ­inside a shipping container ­measuring about 6.1 metres long and 2.6 metres high, it would be able to generate 10 megawatts of heat, which, if converted into ­electricity, would be enough to power some 50,000 households.

It is also capable of running for years or even decades without ­refuelling, and scientists say that because it produces neither dust nor smoke, even on a small island a resident would hardly notice its existence.
