Title: Nuclear fuel pellet and production thereof
Inventor: MATSUMOTO TOSHIO
IPC: G21C3/62
Filed: 1989-12-14
Abstract: PURPOSE:To drastically decrease the release of gaseous fission products and gas swelling compared to conventional pellets by molding the peripheral part and central part of the pellet by different stages and integrally sintering the pellet. CONSTITUTION:First UO2 powder 13 having high activity is formed as a columnar molding 16 by a preceding press 15 and second UO2 powder 14 having low activity is mixed with SiO2-Al2O3 powder and is then formed as a cylindrical molding 19 by a preceding press 18. The molding 16 is then inserted into the hole part of the molding 19 and is again pressed 21 to obtain a columnar molding 22. This molding is subjected to the sintering in a reducing atmosphere to obtain the integral type pellet 24. The crystal grain size is about 40mum in the central region of this pellet 24. This crystal grains larger by about 4 times than the size in the outer peripheral region of the pellet 24 are thereby obtd. As a result, the gaseous fission products are liable to be released through the grain boundaries in the central part of the diamentral direction of the pellet where the temp. is high. Since the generation of the gaseous fission products and arrival thereof at the grain boundaries take time, the bubbles are hardly accumulated at the grain boundaries and the swelling of the pellet is decreased.
