An Analysis of a Spent Fuel Transportation Cask Under Severe Accident Conditions

The U.S. Nuclear Regulatory Commission has established Title 10 of the Code of Federal Regulations Part 71 section 73(c)(4), (10 CFR 71.73(c)(4)) which requires radioactive material transportation packages to resist a consuming 30 minute fire in order to prevent a release of radioactive material to the environment. Transportation package designs must be evaluated to ensure survivability in the case of a fire accident.
