Definitions
- the invention relates to nuclear engineering, in particular, to the technology for the manufacture of pelletized oxide nuclear fuel for fuel elements of nuclear power plants.
- Patent EP e 0249549 from 16.12.87 MKI G 21 C 3/62 A known method [Patent EP e 0249549 from 16.12.87 MKI G 21 C 3/62)], in accordance with which for the manufacture of sintered tablets using a mixture of powder of triuran octoxide (uranium oxide) with uranium dioxide powder
- Sintered tablets obtained by this method are characterized by low density and high
- Sintered tablets have rather stringent requirements in terms of density, geometric dimensions, mechanical strength, microstructure, thermal stability, and other parameters.
- the conversion of uranium oxide with a density of 8.39 g / cm 3 to uranium dioxide with a density of 10.96 g / cm 3 is accompanied by a decrease in the volume of particles and, accordingly, a decrease in their linear size.
- a new particle of uranium dioxide formed during the reduction of particles of oxide of oxide moves away from the remaining stationary particles of uranium dioxide matrix.
- additional porosity is created, the value of which will depend on the grain size of uranium oxide. It is known that the porosity in a compressed tablet can be reduced by increasing the pressing pressure, however, this increases the wear of the press tool, the likelihood of the formation of re-pressing cracks, and a decrease in direct yield.
- the present invention is the development and creation of a method for the manufacture of nuclear fuel pellets that meets the increased requirements for mechanical strength, microstructure of sintered tablets.
- This circumstance contributes not only to a decrease in the initial porosity of the compressed tablet and to a decrease in the size of most of the “gaps” between uranium dioxide particles with a shorter ion diffusion length during sintering, but also provides an increase in the grain size of the sintered tablet.
- the invention meets the patentability criterion.
- the method is implemented as follows.
- Example 1 300 g of ceramic grade uranium dioxide powder obtained by dry conversion of uranium hexafluoride (the total specific surface area of the powder is 2.8 m 2 / g) is poured with a layer of 10-15 mm into a stainless steel pan, placed in a muffle preheated to a temperature of 160-U0 ° C, and stand in it for 3-5 minutes with the muffle door open. Then the baking sheet with the powder is removed from the muffle and cooled to room temperature.
- the prepared mixture is pressed at a specific pressure of 1100-1200 kg / cm 2 in a matrix with a diameter of 20 mm;
- FIG. 1 shows the grain size distribution of sintered tablets as determined by optical microscopy.
- DIESED 2-distearylethylenediamine
