The Chinese have long responded to rapidly growing demand in energy by pursuing progress in all technologies. Now, they seem to be about to have a breakthrough with nuclear power, announcing that they plan to have an advanced reactor online by the end of next year.
The hopeful design is a high-temperature, gas cooled, pebble-bed reactor. The key advantage is its passive safety – it is unable to melt down. This is due to the fact the uranium fuel is encased in pebble sized balls, preventing the fuel from breaking down, and also because the reactor is meant to operate at high temperatures, so does not need constant cooling systems which can fail. The pebbles also lessen waste problems by making the uranium easier to dispose of. Eventually China aims to recycle all of its nuclear waste products as part of a sustainable nuclear programme.
The technology itself is not new. It was developed in Germany decades ago, but has never been built on a commercial scale. The construction is underway in the Shandong province south of Beijing and is nearing completion. A series of tests will be conducted this year before energy production can start in 2017.
Successful demonstration of this advanced reactor will be a significant step for nuclear progress not only in China but also in the rest of the world. And the Chinese are determined to take this significant step. As Charles Forsberg, executive director of the MIT Nuclear Fuel Cycle Project, said, “What you are seeing is serious intent.” If this serious intent is translated into reality, it could have global impacts on making energy more sustainable, and the climate more secure.
