This Report summarizes the results of heat transfer inspection of metal cask for spent fuel storage and transportation, which is conducted by Hitachi-GE Nuclear Energy, the manufacturer. To simulate the decay heat of the spent fuel in the metal cask an electric heater was used. The temperature of cask components measured by thermocouple, were then compared with the results of heat removal analysis. The temperatures are within the acceptance criteria, and therefore, it has confirmed that the heat removal performance of metal cask is satisfied.
