A transport container for a 500 kCi tritium storage vessel was developed, which could be used for the transport of metal tritide from Wolsong TRF facility to a disposal site. The structural, thermal, shielding, and confinement analysis were performed for the container in a view of Type B. As a result of structural analyses, the developed container sustained its integrity under normal and accidental conditions. The maximum temperature increase of the inner storage vessel by radiation was evaluated at 134.8 ℃ at room temperature. In 800 ℃ fire test, The thermal barrier of container sustained the inner vessel at 405 ℃ after 30 min, which temperature was allowable for the container integrity since maximum design temperature of inner vessel was 550 ℃. In the evaluation of the shielding, the activity of radiation was nearly zero on the outer surface of inner vessel. Consequently the transport container for a 500 kCi tritium was evaluated to pass all the safety tests including accidental condition, so it was concluded that the designed transport container is proper to be used
