A lithium-air reaction model for the MELCOR code for analyzing lithium fires in fusion reactors

This paper details the initial modifications made to the MELCOR code that a llow it to predict the consequences of lithium spill accidents for evolving fusion reactor designs. These modifications include thermodynamic and tran sport properties of lithium, and physical models for predicting the rate of reaction of, and energy production from the lithium-air reaction. A benchm arking study was performed with this new MELCOR capability. Two lithium-air reaction tests conducted at the Hanford Engineering Development Laboratory (HEDL) were selected for this benchmark study. Excellent agreement was ach ieved between MELCOR predictions and the measured data, when several empiri cally derived coefficients were used. Recommendations for modeling lithium fires with MELCOR and for future work in this area concluded this paper. (C ) 2001 Elsevier Science B.V. All rights reserved.
