Abstract
A sealing function is essential for transportation casks of radioactive materials under both normal and accidental conditions in transportation in order to prevent radioactive materials from being released into the environment. In the safety analysis report, the releasing rate of radioactive materials from the casks into the environment is evaluated using the correlations specified in ANSI N14.5 1977 and 1987. Furthermore, an evaluation method on the leakage rate from the casks is being standardized in the International Organization for Standardization (ISO).
