Abstract

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.
