Definitions
- the invention relates to a nuclear reactor working according to the dual fluid principle with a special liquid metal / fuel mixture as liquid fuel in the liquid fuel line.
- a dual fluid reactor known from EP 2 758 965 B1
- DFR is a new type of nuclear high-temperature reactor with a fast neutron spectrum, which, unlike all other reactor concepts for power plants, works with two separate liquid circuits.
- These two liquid circuits include a primary coolant circuit consisting of a liquid metal for the highly effective removal of the high power density of nuclear emission reactions and a liquid fuel circuit for optimal use and processing of the fuel, whereby the heat transfer of the liquid fuel to the coolant takes place via a pipe system within the gap zone in the reactor core.
- the composition of the liquid fuel is not specified. Two variants are available: a molten salt melt or a liquid metal mixture.
- the optimal composition consists of actinide trichlorides. Due to the high heat transport capacity of the liquid metal coolant, it is possible to remove the high thermal output of the nuclear chain reaction from the reactor core. It is not necessary to dilute the actinide salts. This distinguishes the DFR from the well-known molten salt reactor (MSR), where the molten salt provides both the fissile material and takes over the heat transport and must therefore be diluted. The MSR therefore only comes into consideration with salt eutectics with a low actinide concentration, which results in a lower power density and increased corrosion problems.
- MSR molten salt reactor
- Uranium and even more thorium have melting points that are too high for power plant operation. It is therefore necessary to reduce at least the solidus temperature by adding other metals with sufficiently favorable neutron properties.
- the resulting multi-component alloy does not necessarily have to be a eutectic. Even if the liquidus temperature is above the operating temperature, the mixture can be pumped sufficiently in this mushy phase.
- the object of the invention is therefore to provide a liquid metal fuel for dual fluid reactors which is distinguished by high thermal conductivity, high actinide nuclide density, high power density and a high working temperature, enables continuous removal in a dual-fluid reactor and thus as a fuel in the Fuel line of a dual-fluid reactor can be used.
- the object is achieved by using a molten metal mixture based on a predominant proportion of actinides, in particular actinideutectics, for various Operating modes and breeding cycles are used in a DFR, as described below.
- multi-component alloys or emerging multi-component alloys do not necessarily have to be a eutectic.
- the invention is based on studies which were carried out for accident scenarios where the fissile material overheats and its effects on the cladding tube materials have become apparent. In the case of metallic fissile material, it can melt. The disadvantage is that z. B. Liquefying uranium begins to dissolve the cladding tubes - usually made of stainless steel alloys in the case of fast reactors - the steel alloy elements being dissolved to different extents.
- metal mixtures which are suitable advantageous, in part eutectic, mixtures, preferably of thorium, uranium and plutonium, with chemical elements made from steels such as iron, chromium or manganese.
- Dual fluid reactors are known (cf. EP 2 758 965 B1) and are e.g. B. characterized by a first line for the continuous supply and discharge of a liquid fuel into a core volume in a reactor core vessel, said first line entering the reactor core vessel via an inlet, being guided through the core volume and via an outlet the reactor core vessel, wherein the chain reaction is critical or can run subcritically, leaves again and a second line for a liquid coolant, which is arranged so that the coolant from the second line enters the reactor core vessel via an inlet, flows around the first line and leaves the reactor core vessel again through an outlet.
- the invention accordingly relates to a dual fluid reactor (DFR) which, as liquid fuel in the liquid fuel line, comprises liquid mixtures of metals with a high actinide content as a liquid metal fuel mixture.
- DFR dual fluid reactor
- the proportion of non-actinide metals in the mixture is preferably at most 31 atom% and the proportion of actinides is at least 69 atom%. A maximum deviation of 1% is possible.
- the metals are selected from chromium (Cr), manganese (Mn) and / or iron (Fe).
- Preferred actinides are selected from thorium (Th), uranium (U) and / or plutonium (Pu).
- Thorium is preferably used as Th-232 and, if appropriate, proportions of further isotopes, if spent fuel is used, uranium is preferred as U-233, U-235, U-238, and if appropriate, portions of further isotopes such as U-236, if spent fuel is used , and Plutonium preferably as Pu-239, Pu-240, Pu-241, Pu-242 and optionally portions of further isotopes, if burnt fuel is used, used in the initial charge of the core.
- up to 3 atom% of fission products can be contained in the initial charge and portions of the weak and / or strong fission materials can be substituted by nuclides of transuranic elements.
- the following binary eutectics serve as the basis for liquid metal / fuel mixtures for such a dual fluid reactor:
- binary eutectics have not previously been considered as liquid metal fuel mixtures for nuclear power plants, they are particularly suitable for use in the DFR. They are characterized by a very high actinide concentration, which optimizes the neutron economy and thus the transmutation ability of the reactor. Its melting point is 800 ° C, which qualifies it for operation. The boiling points are well above 2000 ° C, so that the operating temperature can also be increased because the formation of vapor bubbles is far away, corresponding to the lead coolant. The high thermal conductivity makes permanent pumping of the fuel liquid obsolete. Overall, this leads to an increase in the power density and thus to a higher efficiency of the power plant.
- Every critical nuclear reactor requires a sufficiently high concentration of strong fission materials, i.e. nuclides, which can also be fused with thermal and epithermal neutron energies (ie U-233, U-235, Pu-239, Pu-241, i.e. predominantly nuclides with an odd number of neutrons), and not like the weak fissile materials only with high neutron energies (Th-232, U-238, also transuranic nuclides with even neutron numbers).
- Thorium is not critically fissile in any reactor, natural uranium in any reactor with a fast neutron spectrum.
- the concentration of strong fission materials must be increased significantly for rapid fission reactors. Both result in the fact that it does not remain with a binary alloy and probably also does not meet the condition of a eutectic, i.e. H. The solidus and liquidus temperatures coincide. The resulting fission products could initially be completely dissolved in the alloy due to the low mass conversion of fission. However, the outstanding neutron economy of such a DFR allows such long operating times without reprocessing the fuel mix that the concentration can increase so far that agglomeration effects occur.
- the actinide nuclides change due to sterile neutron capture and beta decay;
- protactinium, neptunium and americium are produced.
- the mixtures with more than 2 components and in particular increased fission product concentration may differ in the parameter range from the values for eutectics, but as long as the solidus temperature and the overall viscosity are low enough for pumping, this does not affect the operability.
- the following preferred variants of a metal mixture are used as a fresh inventory for a DFR reactor core:
- Uranium / chromium comes particularly preferably as [79, 81] atom% U, [19, 21] atom% Cr, uranium / manganese as [79, 81] atom% U, [19, 21] atom% Mn and / or thorium / iron as [69, 71] atom% Th, [29, 31] atom% Fe.
- a binary eutectic consisting of [7, 12] atom% U-235, [67, 74] atom% U-238, [19, 21] atom% ⁇ Cr or Mn ⁇ is very particularly preferably used initially. Through conversion during operation, the U-235 portion is successively replaced by plutonium, predominantly Pu-239, with a ternary mixture plus fission products arises.
- a ternary mixture of Pu / U / Cr A ternary mixture consisting of [7, 12] atomic% Pu-239, [67, 74] atomic% U-238, [19, 21] atomic% ⁇ Cr or Mn ⁇ is particularly preferably used initially.
- the Pu portion remains almost constant due to the conversion of U-238.
- U-238 is consumed and replaced by fission products.
- a quaternary mixture of U / Th / Fe / Cr A quaternary mixture consisting of [7, 12] atom% U-233, [1, 4] atom% ⁇ Cr or Mn ⁇ , [59, 64] atom% Th-232 and [25, 29] atom% Fe used.
- U-233 is necessary here as the only strong fissile material. Thorium is only feedstock for consumption to convert to U-233.
- a mixture of Fe and Cr is said to meet the eutectic condition for the quaternary mixture.
- a quaternary mixture of Pu / Th / Fe / Cr acts as the starting inventory for the Thorium cycle for U-233 firing. Since plutonium is much more readily available than U- 233.
- the pentaneous mixture U / Pu / Th / Fe / Cr to U / Th / Fe / Cr is formed temporarily.
- a pent mixture of U / Pu / Th / Fe / Cr is suitable for a hybrid operation, in which the very high neutron yield of plutonium is used, for the maximized incubation of U-233 from thorium in addition to the regeneration of the plutonium from U-238.
- the thorium / U-238 content can be set so that the conversion rate is minimized for burner / incinerator operation.
- substances which are largely inert in terms of neutron physics and which dilute the fissile material, e.g. Zr, Al or Mg. Component proportions also result from burn-off optimization.
- the percentages of substances in the mixtures to be used always add up to 100%.
- Chrome has as Component of alloy compared to manganese in combination with uranium has the advantage of absorbing fewer neutrons, although the difference is not an exclusion criterion.
- Mn can also be used. The use of Mn requires an increase in the concentration of strong fission material for compensation.
- the simulations show that the neutron spectrum is very hard; and this makes several nuclides with an even number of neutrons flammable, ie k inf > 1. These are the nuclides U-234, Pu-240 and Pu-242 which are important for practical operation. The consequence of this is that the conversion rate of the reactor increases suddenly, since the formation of said nuclides no longer constitutes sterile neutron capture.
- the simplest transition mode is the start with slightly enriched uranium (LEU).
- the alloy additive is ⁇ Cr or Mn ⁇ with a constant proportion.
- the plutonium content increases due to the consumption of the U-238 and finally replaces U-235 as a strong fissile, with fission products as mentioned above. to come.
- U-233 is hardly available as a breeding result of the Thorium circle, so that the use of plutonium as a strong fission material from the commercial PUREX reprocessing plants is also planned to start a reactor with Thorium as a breeding material.
- a hybrid operation can also be carried out in cooperation with the PPU, in which plutonium is used its high neutron yield makes the brood surplus neutrons available for the capture of thorium. So much U-238 is added that the used plutonium can be regenerated.
- Frequent processing of the fuel liquid in the PPU means that the intermediate nuclide Pa-233 can be secreted, so that U-233 mainly forms outside the reactor core and is not split in the reactor.
- the composition is a neutron physics optimization task.
- the proportion of ⁇ Cr, Mn ⁇ is a quarter of the added proportion of Pu and U.
- the necessary proportion Fe is 3/7 of Th.
- transuranic elements from irradiated fuel elements of nuclear power plants
- these can usually be mixed into the brood as weak fissile materials.
- the ⁇ Cr, Mn ⁇ and Fe portion is adjusted.
- the incubation material can be diluted by neutron physically inert nuclides (i.e. small neutron absorption cross section and no formation of long-lived radioactive nuclides), e.g. B. with Zr, Mg or Al.
