Abstract

It is proposed the mechanism of melt fragmentation by fuel-coolant interaction (vapor explosion). The criteria of melt surface fragmentation are formulated for cases subcritical and supercritical temperatures of melt-coolant contact surface. These criteria are in agreement with know experimental data about small scale spontaneous and triggered vapor explosions. 8 refs.

Modeling of Melt Droplet Fragmentation Following Vapor Film Destabilization by a Trigger Pulse

Journal Article Leclerc, Eric; Berthoud, Georges - Nuclear Technology

In hypothetical Severe Accident studies for a PWR, a large amount of molten corium may be poured into water. There is then a risk of Steam Explosion. After the premixing sequence in which the melt is more or less dispersed into water, a fine fragmentation process may start, which can lead to an escalation. Such an event is generally triggered by the destabilization of the vapor film surrounding the hot melt droplets. In this paper, an attempt to describe all the successive processes leading to this fine fragmentation is presented.First, a critical analysis of previous models is performed, allowing usmore »« less
Initiation of melt fragmentation in fuel-coolant interactions

Journal Article Drumheller, D - Nucl. Sci. Eng.; (United States)

In many cases, the mixing of drops of hot liquid fuel with a more volatile coolant results in stable film boiling about the drops. At some later time, a disturbance can fragment the drops. This fragmentation increases the contact area between the liquids and results in a violent vaporization of the coolant. An understanding of this fragmentation mechanism is crucial to the prediction of the likelihood of violent fuel-coolant interactions. A fragmentation mechanism is proposed. It is shown how moderate pressure disturbances can cause the symmetrical collapse of a vapor film and allow the coolant to impact the drop. Themore »« less
Effects of Coolant Void Condition on Melt Fragmentation using Simulants in Initial Phase of Metal-fueled SFR Severe Accident

Journal Article Heo, Hyo; Lee, Min; Bang, In; ... - Transactions of the American Nuclear Society

Metal fuel has inherent safety characteristics, especially in severe accident conditions. However, the metal-fueled SFR severe accident scenarios need to be categorized since overall severe accident mitigation strategies have not been prepared. In addition, these mitigation strategies should be classified in specific phases. In an initial phase of metal-fueled SFR severe accident scenarios, fuel melting, and cladding failures would occur. After the occurrence of the cladding breach, the molten metal fuel would be ejected into a coolant channel due to fission gas in fuel cavity or rapid evaporation of sodium bond. This is called Ex-pin phenomena. There are few studiesmore »« less
Thermodynamic pathways to melting, ablation, and solidification in absorbing solids under pulsed laser irradiation

Journal Article Lorazo, Patrick; Lewis, Laurent; Meunier, Michel - Physical Review. B, Condensed Matter and Materials Physics

The thermodynamic pathways involved in laser irradiation of absorbing solids are investigated in silicon for pulse durations of 500 fs and 100 ps. This is achieved by accounting for carrier and atom dynamics within a combined Monte Carlo and molecular-dynamics scheme and simultaneously tracking the time evolution of the irradiated material in {rho}-T-P space. Our simulations reveal thermal changes in long-range order and state of aggregation driven, in most cases, by nonequilibrium states of rapidly heated or promptly cooled matter. Under femtosecond irradiation near the ablation threshold, the system is originally pulled to a near-critical state following rapid (< ormore »« less

Thermal explosions resulting from fuel-coolant interactions

Journal Article Bartusiak, R; Caram, H - Metall. Trans., B; (United States)

High-speed photographic data and pressure traces of thermal explosions from the contact of single drops of ion oxide with water were analyzed according to models describing underwater chemical explosion and cavitation bubbles. The objective was to develop a simple method for analyzing the microscale hydrodynamics of fuel-coolant interactions (FCI). For a given external pressure and liquid density essentially all the features of the radial motion of the explosion bubble, including the total energy release, are uniquely determined by a single parameter - the bubble period. Nearly all of the heat transfer from fuel to coolant occurs during the 10/sup -5/more »« less
