| 摘 要： | 针对中国工程物理研究院混合堆次临界能源包层,提出了一种新型的严重事故缓解系统——工程通道注水系统,采用通道注水的方法直接导出燃料区衰变热,同时与非能动安全壳冷却系统结合,实现燃料区非能动长期冷却的建立,阻止燃料区熔化进程发展,保证次临界能源包层的完整性。在保守假设条件下,当燃料区温度达到1220℃时,工程通道注水系统投入运行即可完成严重事故缓解功能。

| Abstract: | A new type of engineering-channel water flooding system was proposed to mitigate severe accidents for the subcritical energy cladding of China Academy of Engineering Physics (CAEP)s hybrid reactor. The decay heat of the fuel region can be discharged by injecting cooling water in this system, and the combination of this flooding system with the passive containment cooling system contributes to the establishment of a long-term passive cooling of the fuel region, which prevents the core melting and ensures the integrity of the subcritical energy cladding. Under conservative assumptions, when the fuel temperature reaches 1220 ℃, the engineering-channel water flooding system will start to protect the subcritical energy cladding. |
