NON-REFUELING LONG-LIFE SMALL MODULAR LIQUID METAL COOLED FAST REACTOR SHUTDOWN SYSTEM USING NEUTRON ABSORBER FOR CORE MELT DOWN ACCIDENT

摘要

The present invention relates to a fuel-free long-period small liquid metal cooling high-speed reactor shutdown system using a neutron absorbing material in the case of a core melting accident, and the transformation of nuclear fuel using _{Eu 2} O ₃ or EuB _{6, which is a neutron absorbing material in the case of a core melting accident} This is to prevent the core from reaching the re-critical state due to overheating and movement, thereby preventing the nuclear fission reaction of the core from occurring, thereby suppressing the occurrence of an emergency situation.
