| titleOfInvention | An analytical method for measuring the specific surface area of plutonium dioxide and neptunium dioxide powder |
| abstract | The invention belongs to the technical field of post-processing analysis, in particular to an analysis method for measuring the specific surface area of plutonium dioxide and neptunium dioxide powder. Weigh a certain mass of powder sample into the sample tube, take the standard sample of specific surface area, start up to preheat, turn on nitrogen and helium, adjust the inlet pressure within the operating range of the instrument, and connect the sample tube to the heating hole of the degassing station At room temperature, set the heating temperature, degas at room temperature, put it into the heating hole for degassing, and finally take it out and degas it at room temperature, cool it, remove the ice or water in the Dewar flask, and add liquid nitrogen into the Dewar flask to the distance from the flask. , equilibrate at ambient temperature, input the sample mass, place the dewar flask that has reached temperature equilibrium on the lifting rack, and set the instrument measurement parameters. Start the measurement, and after the measurement is over, the instrument gives the specific surface area value of the powder sample. The invention adopts the nitrogen adsorption method to measure the specific surface area in a wide range, and is suitable for measuring the specific surface area of plutonium dioxide and neptunium dioxide powder samples in spent fuel reprocessing plants. |
