FIELD: nuclear power engineering; fuel rods for water-moderated water-cooled reactors. n SUBSTANCE: proposed fuel rod designed for use in water-cooled water-moderated power reactors such as type VVER-1000 reactor has fuel core disposed in cylindrical can. Outer diameter of fuel rod is chosen between 7.00 . 10 -3 and 8.79 . 10 -3 m and fuel core diameter is between 5.82 . 10 -3 and 7.32 . 10 -3 m and mass, between 0.93 and 1.52 kg, fuel core to fuel rod length ratio being between 0.9145 and 0.9483. n EFFECT: reduced linear heat loads and fuel rod depressurization probability, enlarged variation range of reactor power, optimal fuel utilization. n 7 cl, 3 dwg |
