As far as I know, 200 or 300 megawatts are viewed as the largest thermal power in many foreign countries. The idea of 400 megawatts was raised by China for the first time."

China National Nuclear Corporation officially unveiled its independently-developed 400-megawatt low-temp thermo nuclear reactor for central heating Tuesday in Beijing.

It is the largest in-development project of its kind around the world, showing that China has made huge progress in trying to replace traditional coal with nuclear energy for heating.

With its thermal power reaching 400 megawatts and the capacity to cover an area of around 20 million square meters, the Yanlong low-temp thermo nuclear reactor can provide clean heating for 200,000 three-bedroom residences.

"Generally speaking, there is a test period of many projects of its kind. Providing safe heating for 168 hours means that this system can work safely and stably in the future. As far as I know, 200 or 300 megawatts are viewed as the largest thermal power in many foreign countries. The idea of 400 megawatts was raised by China for the first time," said Ke Guotu, chief designer of the 400-megawatt Yanlong low-temp thermo nuclear reactor for central heating under the China National Nuclear Corporation.

Compared with the traditional coal-fired heating method, nuclear energy is greener. A 400-megawatt low-temp thermo nuclear reactor for central heating can replace the use of 320,000 tons of coal, thus reducing 3,200 tons of emissions as well as 100,000 tons of ashes at the same costs.

The reactor is also designed to be safe in the long run.

"This reactor has three water pools, retaining 5,000 tons of water in total. Even if an earthquake or tsunami happened to my reactor, making it unable to stop, the water in it cannot be dried within one month, and my reactor will not melt down unless the water is boiled away," said Ke.

Wang Naiyan, an academician of the Chinese Academy of Sciences, added that The radioactive hot water will not flow into the separation loop, nor to the heating side.

The low-temp thermo nuclear reactor for central heating has been used by countries such as Russia and Switzerland for over 30 years. Although China started research in this area in the 1980s, it has made breakthroughs in several key technologies. In the next stage, the nuclear heating technology will enter the trial demonstration period.

"We have set three steps for developing the project. The first is a demonstration and verification of the 400-megawatt Yanlong low-temp thermo nuclear reactor for central heating, the second is to launch a trial project which is expected to start by the end of next year, and the third is to widely promote the use of nuclear heating," said Li Xiaoming, executive assistant of the China National Nuclear Corporation.
