AI Technical Summary
Existing miniaturized nuclear reactors have low core power and inadequate reactivity control, resulting in insufficient nuclear safety, especially in the event of an accident where it is difficult to quickly shut down the nuclear reaction.
It employs a multi-layered annular fuel design, including a shell, multi-layered annular fuel elements, graphite moderator, reflector layer, control rod drive mechanism, and radiation shielding layer. The position of the control rods is precisely controlled through electromagnetic drive and mechanical structure to ensure reactivity stability and rapidly stop the nuclear reaction in the event of an accident.
It achieves high-power stable control of the portable reactor during normal operation and rapid and safe shutdown in case of an accident, ensuring the portability and safety of the reactor.
