Please direct future questions to the LAMMPS mailing list. There is a substantial scientific literature going back decades on the use of MD to study fission gas diffusion and aggregation (bubble formation) in metals.  Some of this will translate directly to molten salts.  The challenge always is handling the timescales, which are generally far beyond the 100's ns accessible with MD. See for example the work of Brian Wirth on H/He/W systems.

Subject: [EXTERNAL] LAMMPS to Determine Fission Gas Outgassing Rate




I'm looking into Fission Gas formation in Molten Salts.


Given a rate of fission products being produced,

Can I use LAMMPS to determine either

a) the rate of fission gas bubble formation in molten salts

b) the rate of fission gas outgassing from the molten salts.
