Approved optimized sub-system of FTsalt-SALT.

 

Li,Na,K,Mg,Ca,Sr,Ba//Cl,F (dilute: O,OH)

 

(Chlorides and fluorides of Li, Na, K, Mg, Ca, Sr and Ba with O[2-] and OH[-] in dilute amounts.)

 

Evaluated and optimized at all compositions including reciprocal systems (systems with two or more cations and two or more anions), with the exception of the Ba-containing reciprocal systems (which are only predicted from the model parameters for the common-ion binary sub-systems).

Evaluations for O and OH in dilute solutions rich in fluorides are less precise than when rich in chlorides.

 

Possible miscibility gap in reciprocal systems. Use I option.

 

Density model available for the NaCl-KCl-MgCl2-CaCl2 and LiF-NaF-KF-MgF2-CaF2 molten salt systems. Approximate density calculations may be performed for the entire system Li, Na, K, Mg, Ca // Cl, F : all binary common-cation systems of the type LiCl-LiF, MgCl2-MgF2,… and all LiCl-based chloride binary systems of the type LiCl-NaCl, LiCl-MgCl2,… are then assumed to be ideal (in terms of the volumetric properties). In the Menu Window of Equilib, select the liquid solution FTsalt-SALTA and check the box “use only molar volume data” or the box “use V & phys. property data”. In the Results Window, the density value (in gram∙cm-3) calculated from the model is displayed (in parentheses) at the 2nd line of the block corresponding to the liquid phase. A system density (in gram∙cm-3) that takes into account the available density data for all phases at equilibrium (liquid + 1 or more solid phases) is displayed below the integral property table.

Molten salt solution of all fluorides, chlorides, bromides, iodides, nitrates and hydroxides of Li, Na, K, Rb and Cs.

 

All binary systems (AX-AY and AX-BX) have been evaluated and optimized, with the exception of : LiI-LiNO3, RbF-RbNO3, RbF-RbOH, RbCl-RbNO3, RbBr-RbOH, RbI-RbNO3, RbI-RbOH, CsF-CsOH, CsCl-CsOH, CsBr-CsOH, CsI-CsOH and CsI-CsNO3 for which ideal liquid solutions are assumed.

Reciprocal ternary systems (those containing two cations and two anions) optimized only for fluorides and chlorides of Li, Na and K (as in FTsalt-SALTA). Other reciprocal ternary interactions are estimated. Hence, calculations for most multicomponent common-ion systems should be good, but calculations for multicomponent reciprocal systems (containing 2 or more cations and 2 or more anions) will not be as good if any of Rb, Cs, Br, I, NO3 or OH are present.

 

Possible miscibility gap in reciprocal systems. Use I option.

 

FTsalt-SALTE is the only approved FTsalt-SALTx solution containing Br and I. OH and NO3 are also found in FTsalt-SALTF. (OH is also found in other FTsalt-SALTx solutions, but only in dilute amounts.)

Other reciprocal ternary interactions are estimated. Hence, calculations for multicomponent common-ion systems should be good, but calculations for multicomponent reciprocal systems (containing 2 or more cations and 2 or more anions) will usually not be as good if any of NO3, OH, SO4 or CO3 are present.

 

Possible miscibility gap in reciprocal systems. Use I option.

Approved optimized sub-system of FTsalt-SALT.

LiF-ThF4-UF3-UF4-PuF3-PuF4-CrF2-CrF3-NiF2-MoF5.

 

This FTsalt molten salt solution is dedicated to the LiF-ThF4-UF3-UF4-PuF3-PuF4 system for the so-called Molten Salt Nuclear Reactors (MSBR Molten Salt Breeder Reactors for example). It has been developed in collaboration with the PECSA Laboratory of the Université Paris VI (Jussieu), in support of the French CNRS / European proposal for the development of a molten salt reactor technology. ITU-Karlsruhe (Germany) was also involved in the development.

The database has been developed to predict the following :

·       The LiF-ThF4 liquidus and eutectic temperatures ;

·       The solubility of PuF3 in LiF-ThF4 melts ;

·       The impact of the nuclear conversion of ThF4 into UF4 on the solubility of PuF3 in the melt (this includes the Lix(Th,U)yF4y+x solid solutions) ;

·       Estimation of the U3+/U4+ and Pu3+/Pu4+ oxido-reduction behaviour.

In order to evaluate the oxido-reduction behaviour of the molten salt solution contained in Ni-Cr-based alloys (such as Hastelloys), the components CrF2, CrF3, NiF2 and MoF5 were added to the liquid phase as ideal components (i.e. their Gibbs energies g0liquid are included, but these components mix ideally with all other components).

SPECIAL MEASURES MUST BE TAKEN IF YOU USE FTsalt-SALT?

These measures are a result of the two-sublattice-model used for this solution.

 

IF YOU DO NOT TAKE THESE MEASURES, THE CALCULATIONS MAY BE COMPLETELY ERRONEOUS!!

 

Right click on FTsalt-SALT? and then go through the list of components to make sure that the selected components (those marked with a +) constitute a complete set of cation/anion pairs. For example, suppose that the selected components contain cations A, B and C and anions X, Y and Z. There must then be exactly 9 selected components of all possible pairs: AX, AY, AZ, BX, BY, BZ, CX, CY, CZ. If this is not the case, you will have to de-select certain components (click on the + to remove it) until this criterion is satisfied.

 

If AlCl3 is present do NOT use FTsalt-SALT?. Use FTsalt-SALTC or FTsalt-SALTI.

 

Possible miscibility gaps in reciprocal systems (systems with 2 or more cations and 2 or more anions.) Use I option.

[FTsalt-oP28?]      ?beta-K2SO4

GENERAL SOLID SOLUTION WITH THE beta-K2SO4 STRUCTURE

(beta-K2SO4 Pearson : oP28; Space group : Pnma (62); prototype : K2SO4)

 

The components that can be used for the calculations are :

(Na,K,Cs)2[MgCl4,CoCl4,ZnCl4,SO4,CO3,CrO4]

 

Solid solution of Na2MgCl4, K2MgCl4,......, Na2SO4,......, Na2CO3,......, Cs2CrO4 with Na, K and Cs on the cationic sublattice, and MgCl4, CoCl4, ZnCl4, SO4, CO3, and CrO4 on the anionic sublattice. Not all binary and ternary sub-systems have been evaluated and optimized. Sub-systems which have not been evaluated and optimized have been approximated.

 

For the approved sub-systems of components for which data have been evaluated and optimized, scan up to see the descriptions of FTsalt-oP28A, …, oP28D.

 

SPECIAL MEASURES MUST BE TAKEN IF YOU USE FTsalt-oP28?

These measures are a result of the two-sublattice-model used for this solution.

 

IF YOU DO NOT TAKE THESE MEASURES, THE CALCULATIONS MAY BE COMPLETELY ERRONEOUS!!

 

Right click on FTsalt-oP28? and then go through the list of components to make sure that the selected components (those marked with a +) constitute a complete set of cation/anion pairs. For example, suppose that the selected components contain cations Na, K and Cs and anions X, Y and Z. There must then be exactly 9 selected components of all possible pairs: Na2X, Na2Y, Na2Z, K2X, K2Y, K2Z, Cs2X, Cs2Y, Cs2Z. If this is not the case, you will have to de-select certain components (click on the + to remove it) until this criterion is satisfied.
