Abstract:
Based on the current energy technology and technical development of nuclear power, nuclear energy is indispensable for the energy transformation for clean, low-carbon and sustainable development, and the large advanced pressurized water reactor with high safety and reliability would be the main support of energy development in the next 30 years. Facing the challenges in the National Science and Technology Key Project for large advanced pressurized water reactor, this paper states how to resolve three critical problems such as the high residual heat removal, core melt retention and radioactivity confinements thus to ensure the elimination of significant release of radioactivity or to reduce the nuclear safety risks at design stage for the mass construction of nuclear power plants.
