The Joint Research Centre Molten Salt Database (JRCMSD) is an extensive thermodynamic database describing the key fuel and coolant systems for Molten Salt Reactor technology.
Overview on the available data
The database contains assessed data for
- binary, ternary and higher order phase diagrams for fuel components (U, Th, Pu),
- fuel solvent and coolant components, and some
- fission and corrosion product components.
Regularly updated data
The database is being continuously validated and expanded by novel experimental data and thermodynamic assessments. It provides strong and reliable tool to estimate thermodynamic properties (selected ones are listed below) of fresh fuel (and/or coolant) salts. JRCMSD also provides insight into properties change influenced by accumulation of fission products during operational lifetime of the molten salt reactor.
The same is true for prediction of corrosion effects of the salt towards the structural materials. Universities, research organizations, reactor designers, regulators or e.g. licensing authorities can take profit of the database.
JRCMSD - historical development & partners
The database has been developed since 2002 at the European Commission’s Joint Research Centre.
In recent years JRCMSD became very demanded by various research groups that perform studies on molten salt reactor systems.
Nowadays, the JRCMSD database is developed within an international collaboration, chaired by the JRC.
The following partners involved (in alphabetic order):
- CEA
- JRC
- Ontario Tech.
- Orano
- Delft University of Technology
The development of the database is open for any interested organization, subjected to signature of a collaboration agreement.
Using the database
Selected properties that can be calculated using the database:
- Melting point
- Precipitate formation
- Heat capacity
- Vapour pressures and gas speciation
- Boiling points
- Fusion enthalpy
- Heat of vaporization
- Solubility of actinides/fission products/corrosion products
- Redox potential (corrosion potential)
- Basic thermodynamic data such enthalpy, entropy and Gibbs energy
Since the database provides (in most of the cases) a full thermodynamic assessment of the studies system, all the above given properties can be calculated with respect to composition variation, allowing e.g. fuel composition optimization with respect to key properties.
Database files compatibility
The database files are provided in a format compatible with FactSage® software. However, they can be used in other computational thermodynamic software, provided that the modified quasi chemical model is implemented (appropriate file converter might be applicable).
The database is in an encrypted format, supported by the FactSage software, v8.2 and higher; For EU and Asian clients of FactSage the files can be used directly, for North American region, the files must be first activated by the FactSage developer and on individual basis (fees may be applicable).
