The objective of the work reported is to experimentally and analytically study the dominant mechanisms in fuel-coolant thermal interactions which could lead to vapor explosions. The exploration of mechanisms is focused in three areas: (1) mechanisms responsible for fragmentation in molten metal droplet experiments (including assessment of the validity of the proposed Spontaneous Nucleation Mechanism), (2) thermal stress initiated fracture as a fragmentation mechanism, and (3) possible mechanisms of energy dissipation due to heat transfer during the HCDA expansion. Work being performed in these areas is briefly described.
