Phenomenological studies on melt-coolant interactions in the ALPHA program
TLDR
In this article, a series of experiments to investigate melt-coolant interactions have been performed as part of the ALPHA program at JAERI, where melt simulating a molten core was dropped into a pool of water and volume fractions of the melt, water and steam in the mixing region prior to the occurrence of spontaneous steam explosions were quantified.About:

Vapor explosions in light water reactors: A review of theory and modeling
TL;DR: A comprehensive review of vapor explosion theory and modeling can be found in this paper, where the effect of scale on the mixing process coupled with the explosion propagation and efficiency is discussed. But, as discussed in this paper, some specific fundamental issues are either not well understood or require experimental verification of theoretical hypotheses.

Detonation of fuel coolant explosions
S.J. Board,R. W. Hall,R. S. Hall +2 more
TL;DR: In this paper, a simple one-dimensional model of a system in which the two liquids are initially coarsely mixed, and show that there is the possibility of an extremely violent thermal explosion, the structure of which is analogous to that of a detonating chemical explosion.
An assessment of steam-explosion-induced containment failure
TL;DR: In this paper, a probabilistic framework is proposed to quantify the likelihood of steam explosion induced (cap alpha-mode) containment failure from core melt accidents in commercial light water reactors.
