1. A neutron absorber synthesis system comprising:
a pre-processing unit to which radioactive waste including boron is supplied from an outside and inflows to an inside and a compound is produced by removing moisture of the radioactive waste by heat treatment by a first heat source;
a boron carbide synthesizing unit to which the compound produced from the radioactive waste is inflowed inside and a boron carbide is synthesized from a raw material containing the compound and carbon by heat treatment by a second heat source; and
a waste activated carbon processing unit treating a waste activated carbon into an activated carbon and supplying the activated carbon to the boron carbide synthesizing unit,
wherein the waste activated carbon processing unit comprising:
a main body part including an input part of the waste activated carbon supplied from outside and an exhaust part for discharge after treatment,
a microwave heat treatment part provided on a microwave reaction section in the main body part and irradiating a microwave to the waste activated carbon for heat treatment,
a conveyor belt transporting part provided on a transporting section of the waste activated carbon and transporting the waste activated carbon to the microwave reaction section, wherein the boron carbide synthesizing unit receives the raw material including the activated carbon from the waste activated carbon processing unit,
a controller adjusting a microwave power and a conveyor belt speed in the waste activated carbon processing unit, and
a gas analysis unit analyzing an exhaust gas generated in the waste activated carbon processing unit, and
wherein the controller is configured to control a processing temperature and a processing time of the waste activated carbon by adjusting the microwave power and the conveyor belt speed based on information of the exhaust gas analyzed by the gas analysis unit.
