Description
Technical field
The present invention relates to nuclear material preparing technical field, relate in particular to a kind of sol-gal process that is applicable to and prepare continuous operation charging gear and the method in the uranium dioxide core core technique of high temperature gas cooled reactor spheric fuel element.
Background technology
Sol-gal process is prepared ceramic microsphere process application in the uranium dioxide core core of preparation high temperature gas cooled reactor spheric fuel element.This uranium dioxide fuel core core requires 500 microns of left and right of diameter, and dimensional discrepancy is little.
Sol-gal process is prepared uranium dioxide core core and is mainly contained following steps:
1, dissolve, by triuranium octoxide (U
3o
8) powder is dissolved in nitric acid, is configured to the uranyl nitrate solution of certain uranium atom concentration;
2, boil glue, in uranyl nitrate solution, add urea by certain metering ratio, evaporation and concentration certain hour at a certain temperature, adds after cooling thickening agent to adjust viscosity, obtains glue;
3, disperse granulation, the glue of getting ready is moved in head tank, promoting glue with certain pressure flows along pipeline, glue is finally admitted to the vibrating nozzle with certain frequency vibration, from flowing out, vibrating nozzle disperses to become the drop that has certain size, this step needs the accurate flow of controlling, because the difference of flow directly causes the deviation of drop size;
4, gelling balling-up, drop forms afterwards first through air zone, rely on the surface tension of self to form spherical, spherical droplets is again by ammonia district, drop and ammonia generation gelling reaction make surperficial precuring and have certain intensity, enter afterwards ammoniacal liquor district and carry out further gelling reaction and become gel ball;
5, ageing, when gel ball has just formed, gelling reaction only completes at gel ball near surface, gel ball internal-response needs regular hour and temperature, therefore need that gel ball is placed in to ammoniacal liquor and add thermal aging 1～3 hour, gel ball is reacted completely, become the spheric grain that has uniformly some strength;
6, washing, uranyl nitrtate reacts with ammoniacal liquor and generates ammonium diuranate and ammonium nitrate, and ammonium diuranate is required composition, and ammonium nitrate is objectionable constituent, easily in subsequent technique, causes little ball fractured, therefore ammonium nitrate must be removed, method is washing repeatedly.Washing needs 3～5 times, and first pass uses 1%～2% weak aqua ammonia, and several all over using deionized water subsequently, each washing lotion need to be tested its concentration of nitric acid, guarantees that nitrate radical content is enough low;
7, dry, the bead after washing is dry by vacuum rotating seasoning, need to control temperature, vacuum tightness and rotational speed, to ensure that dry run fully completes and can not cause the destruction of bead;
8, roasting, dried bead need to be at roasting kiln roasting, and to slough the organic components in bead, the principal ingredient of bead becomes orange oxide simultaneously;
9, reduction, roasting ball, in reduction furnace, is reduced to uranium dioxide under hydrogen atmosphere, need to ensure suitable reduction temperature and sufficient reductive agent and sufficient recovery time;
10, sintering, the bead after reduction, under hydrogen atmosphere, 1400～1600 degrees Celsius of lower sintering 3～5 hours, becomes uranium dioxide core core;
11, screening and sorting, through screening and sorting step, can obtain size homogeneous, the uranium dioxide core core that sphericity meets the demands.
In the above-mentioned step of preparing uranium dioxide core core, it is preparation technology's key that step 3 is disperseed granulation, is also that technique realizes quantity-produced bottleneck in enormous quantities.Because the adhesive liquid quantity of preparing core core need to meet criticality safety, the stored adhesive liquid quantity of each container must be lower than critical mass, or head tank is safe by geometry.But the head tank of safe by geometry is flat or longilineal, volume will certainly cause space hold too large after strengthening, and therefore answer the volume of limiting pressure tank, but this has limited productive capacity.For meeting continuous need of production, also to meet criticality safety, it is impracticable using single head tank.
