A series of research and development (R&D) projects has been launched by China's National Energy Administration (NEA) to improve the country’s emergency response capabilities at nuclear power plants in the event of an extreme disaster.
The NEA said that the projects are aimed at improving safety-related technology employed in Chinese nuclear power plants, taking into account lessons learned from the Fukushima accident in Japan.
A total of thirteen R&D projects are to be conducted by China National Nuclear Corporation (CNNC), China Guangdong Nuclear Power Corporation (CGNPC) and the Institute of Nuclear and New Energy Technology in cooperation with Tsinghua University. Engineers and researchers will work to develop advanced nuclear power safety technology through targeted research and plant site analyses, the NEA said.
The R&D projects will include the development of passive emergency power supply and cooling water systems, as well as development of passive containment heat removal systems. The projects will also analyse the impact of multiple simultaneous external events and response measures. Research into beyond design basis earthquake and external flooding, as well as measures for the prevention and mitigation of used fuel accidents will also be conducted. Projects will also cover beyond design basis accident mitigation equipment and systems, while others are aimed at developing hydrogen control devices and emergency rescue robots. Other projects will study the monitoring and treatment of contaminated ground and water.
All the projects are expected to be completed by 2013. According to the NEA, implementation of the results will improve the safety of China's second-generation nuclear power plant technology by lowering the probability of large early radioactive releases and reactor core damage.
