The invention discloses a glass solidifying body protection system. The system comprises a high-temperature area and an insulation area which are adjacent and are defined by a shell body (12), wherein one side wall of the high-temperature area is provided with a first shielding door (8); the top of the high-temperature area is provided with a transition interface channel (7), and a side wall between the high-temperature area and the insulation area is provided with a second shielding door (16); another side wall of the insulation area is provided with a third shielding door (5), and the glass solidifying body protection system further comprises a storage vessel (1), a transfer system (2), a jacking clamping mechanism (3), a multi-stage heating device (4), a multi-layer protective device (6) and a control system (11). By virtue of the glass solidifying body protection system, a glass body with stable performance is effectively formed and is prevented from chapping, and radioactive waste can be advantageously stored for a long term.
