Analysis of heat transfer and solidification within CANDU corium

Severe nuclear accidents which result in substantial damage to the reactor core have the potential to release radiation into the environment if the integrity of the reactor vessel is not maintained. In the event of a full loss of core cooling, the expected failure mechanism for Canada Deuterium Uranium (CANDU) calandria vessels is thermal stresses, which are influenced by the heat transfer within the corium. The current study uses computational …
