Thermal Analysis of Spent Nuclear Fuel Transportation Cask Shielded With Phase Change Material

Abstract

The "Closed Fuel Cycle" model, in which spent nuclear fuel is viewed as a resource, has found support in India. The methods used in India to handle nuclear waste are equivalent to those used elsewhere and adhere to International Atomic Energy Agency (IAEA) regulations. In accordance with the waste management procedures, Cat-III and Cat-IV high beta-gamma (alpha and non-alpha) waste canisters must be temporarily stored inside designed storage vaults. Depending on the radioactivity of the canisters, they are eventually disposed of in safe concrete tunnels or deep geological repositories. However, since this nuclear waste is radioactive in nature, transporting it from the facility to the dump yards or vicinity has proven to be a major obstacle for many studies. Contact with this waste can cause serious bodily harm as well as cell damage to any nearby living things. In this research, we look at how to make a nuclear waste storage container that can endure extreme heat, pressure, and shock. Researchers examined the thermal conductivity, compressive strength, and latent heat of different PCM materials to discover which is most efficient for carrying nuclear waste barrels.
