Description
MOLTEN SALT COMPOSITION
[0001] The present invention relates to a molten salt composition, in particular, for use in nuclear fission and fusion reactors, and solar power plants.
[0002] Molten salts are excellent heat transfer medium candidates. Molten salts investigated for fusion and fission include fluoride salt systems. Previously studied molten salts use beryllium as a neutron multiplier, which presents a variety of complications. For example, beryllium is toxic and can cause health effects, and its uranium impurity results in problematic activation. Furthermore, beryllium has a limited natural availability, estimated at 100,000 tonnes globally.
[0003] Known compositions which consist of a LiF-PbF2 system have been previously studied, which contain a breeder (Li) and neutron multiplier (Pb). However, these systems also provide a practical limitation. In a comparison of different molten salt chemistries, LiF-PbF2 systems are not suitable due to their high melting temperatures (580 °C), putting such a system at the edge of the capabilities of the structural materials.
[0004] It is an object of aspects of the present invention to provide one or more solutions to one of the above mentioned or other problems.
[0005] According to a first aspect of the present invention there is provided a molten salt composition, said composition comprising a mixture of: a) lithium fluoride b) lead fluoride c) a third metal fluoride salt, and d) optionally, a further metal fluoride salt.
[0006] Advantageously, the addition of a third (and optionally further) metal fluoride salt to the LiF-PbF2 system provides a composition with a lower melting point, which is compatible with structural materials. Suitably, the melting temperature of the composition is less than 550°C, typically less than 500°C, more typically less than 450°C, such as 400°C.
[0007] The addition of the third (and optionally further) metal fluoride salt further provides a composition with a lower melting point, without significantly reducing the concentration of lithium (breeder) or lead (multiplier), therefore maximising the breeding ratio.
[0008] Advantageously, the compositions of the present invention allow LiF-PbF2-based systems to become a viable option and provide compositions which are substantially free of beryllium.
[0009] The composition may comprise from 15 to 50 mol% of component a), based on the total number of moles of a) to d). Typically, the composition comprises from 20 to 45 mol% of component a), more typically, from 25 to 40 mol% of component a), based on the total number of moles of a) to d). Suitably, the composition comprises at least 15 mol% of component a), based on the total number of moles of a) to d), typically, at least 20 mol%, more typically, at least mol% of component a), based on the total number of moles of a) to d). The composition may comprise less than 50 mol% of component a), based on the total number of moles of a) to d). Typically, the composition comprises less than 45 mol%, more typically less than 40 mol% of component a), based on the total number of moles of a) to d).
[0010] The composition may comprise from 15 to 60 mol% of component b), based on the total number of moles of a) to d). Typically, the composition comprises from 20 to 50 mol% of component b), more typically, from 25 to 40 mol% of component b), based on the total number of moles of a) to d). Suitably, the composition comprises at least 15 mol% of component b), based on the total number of moles of a) to d), typically, at least 20 mol%, more typically, at least 25 mol% of component b), based on the total number of moles of a) to d). The composition may comprise less than 60 mol% of component b), based on the total number of moles of a) to d). Typically, the composition comprises less than 50 mol%, more typically less than 45 mol% of component b), based on the total number of moles of a) to d).
[0011] The composition may comprise from 15 to 50 mol% of component c), based on the total number of moles of a) to d). Typically, the composition comprises from 20 to 45 mol% of component c), more typically, from 25 to 40 mol% of component c), based on the total number of moles of a) to d). Suitably, the composition comprises at least 15 mol% of component c), based on the total number of moles of a) to d), typically, at least 20 mol%, more typically, at least 25 mol% of component c), based on the total number of moles of a) to d). The composition may comprise less than 50 mol% of component c), based on the total number of moles of a) to d).
Typically, the composition comprises less than 45 mol%, more typically less than 40 mol% of component c), based on the total number of moles of a) to d).
[0012] When a further metal fluoride salt is present, the composition may comprise 15 mol% or less of component d), based on the total number of moles of a) to d). Suitably, the composition may comprise 10 mol% or less, more suitably, the composition may comprise 7 mol% or less of component d) [0013] The purity level of each of components a) to d) may independently be at least 95%, typically 97%, such as 99%.
[0014] It is understood that component c) refers to a further metal fluoride salt, i.e., that the third metal fluoride salt is selected from a different metal fluoride salt than lithium fluoride and lead fluoride. Typically, the third metal fluoride salt has a chemical formula MxFy where M is a metal and X and Y represent the number of metal and fluorides respectively in the chemical formula of the metal fluoride. Typically, the third metal fluoride salt is selected from sodium fluoride (NaF), potassium fluoride (KF), magnesium fluoride (MgF2), zirconium fluoride (Zr4F), aluminium fluoride (AIF3) or rubidium fluoride (RbF). Preferably, the third metal fluoride salt is selected from sodium fluoride (NaF) or potassium fluoride (KF).
[0015] It is understood that component d) refers to a further metal fluoride salt, i.e., that the further metal fluoride salt is selected from a different metal fluoride salt than lithium fluoride, lead fluoride and the third metal fluoride salt. Typically, when a further metal fluoride salt is present in the composition, it has a chemical formula M.Fy where M is a metal and X and Y represent the number of metal and fluorides respectively in the chemical formula of the metal fluoride.
Typically, the further metal fluoride salt is selected from sodium fluoride (NaF), potassium fluoride (KF), magnesium fluoride (MgF2), zirconium fluoride (Zr4F), aluminium fluoride (AIF3) or rubidium fluoride (RbF). For example, when the third metal fluoride salt selected is sodium fluoride (NaF), typically the further metal fluoride salt is potassium fluoride (KF) or zirconium fluoride (Zr4F). When the third metal fluoride salt selected is potassium fluoride (KF), typically the further metal fluoride is sodium fluoride (NaF) or zirconium fluoride (Zr4F).
[0016] The composition may be in a solid (pre-molten) form or molten form. [0017] Typically, the composition is substantially free of beryllium.
[0018] "Substantially free" refers to compositions, or components thereof, containing less than 1000 parts per million (ppm) of any of the elements/components thereof mentioned above.
[0019] The composition may be a mixture selected from LiF-PbF2-NaF, LiF-PbF2-NaF-KF, LiFPbF2-NaF-ZrF4, LiF-PbF2-ZrF4, LiF-PbF2-KF LiF-PbF2-KF-ZrF4,LiF-PbF2-KF-NaF, LiF-PbF2-ZrF4-NaF, or LiF-PbF2-ZrF4-KF systems.
[0020] According to the second aspect of the present invention, there is provided the use of a molten salt composition according to the first aspect, as a heat transfer or heat storage medium.
[0021] According to a third aspect of the present invention, there is provided the use of a molten salt composition according to the first aspect as a breeding material in a fusion reactor, fission reactor, or for solar energy storage.
[0022] According to a fourth aspect of the present invention, there is provided the use of a molten salt composition according to the first aspect in waste purification or metal extraction.
[0023] As used herein, unless otherwise expressly specified, all numbers such as those expressing values, ranges, amounts or percentages may be read as if prefaced by the word "about", even if the term does not expressly appear. The term "about" when used herein means +/-5% of the stated value. Also, any numerical range recited herein is intended to include all sub-ranges subsumed therein. Singular encompasses plural and vice versa. For example, although reference is made herein to "a" third metal fluoride salt, "a" further metal fluoride salt, and the like, one or more of each of these and any other components can be used. Additionally, although the present invention has been described in terms of "comprising", the processes, materials, and coating compositions detailed herein may also be described as "consisting essentially of' or "consisting of'.
[0024] Where ranges are provided in relation to a genus, each range may also apply additionally and independently to any one or more of the listed species of that genus.
[0025] All of the features contained herein may be combined with any of the above aspects in any combination.
[0026] Although a few preferred embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications might be made without departing from the scope of the invention, as defined in the appended 15 claims.
[0027] The invention will now be further described by way of the following non-limiting examples.
