我国核能发展的总体战略是热堆(压水堆)-快堆-聚变堆。核裂变能的可持续发展依赖于铀资源的充分利用和核废物的安全处置,发展快堆技术是解决这两方面挑战的有效现实途径。我国在做好压水堆核电技术升级的同时,应制定快堆核能系统技术开发的整体发展规划,以实现压水堆-快 The overall strategy for the development of nuclear energy in our country is thermal reactor (pressurized water reactor) - fast reactor - fusion reactor. The sustainable development of nuclear fission energy relies on the full utilization of uranium resources and the safe disposal of nuclear waste. Developing fast reactor technology is an effective and realistic way to solve these two challenges. At the same time that China is doing a good job of upgrading nuclear power technology of PWR, an overall development plan for the development of technology for fast reactor nuclear power systems should be formulated so as to realize PWR - fast
