The present embodiment discloses an inherent safety design method, device, and equipment for an ammonia xenon cooled reactor. The method comprises: the core structure material of a helium xenon cooled reactor is graphite, the pressure bearing shell is austenitic 304 stainless steel, and the reactor arrangement is arranged in a horizontal sequential manner; Calculate the reactor core temperature under the condition of loss of helium xenon supply; Determine whether the temperature of the reactor core is lower than the melting point of fuel and structural materials; If so, determine that the helium xenon cooled reactor is an inherently safe reactor. This application utilizes rational core materials and structures, utilizing natural physical laws such as heat conduction, natural convection, and thermal radiation, to enable the safe export of core waste heat without relying on input from external power sources, while leaving only shutdown waste heat after the reactor is shut down. This makes the reactor inherently safe.
