The invention discloses a system and a method for drying radioactive distillation raffinate, and the system comprises a high-integrity container which is used for containing the radioactive distillation raffinate; the condenser is connected with the high-integrity container, and the condenser is used for condensation; the gas-liquid separator is connected with the condenser, and the gas-liquid separator is used for carrying out gas-liquid separation on the materials condensed by the condenser; the vacuum pump is connected with the gas-liquid separator, and the vacuum pump is used for pumping out steam and non-condensable gas in the high-integrity container and maintaining the drying pressure; the gas heater is respectively connected with the vacuum pump and the high-integrity container, and the gas heater is used for heating the non-condensable gas entering the high-integrity container. According to the invention, the drying process is carried out at a relatively low temperature, and the high-integrity contai
