PERFECCIONAMIENTOS EN LA DISPOSICION DE BARRAS DE PELLETS DECOMBUSTIBLE NUCLEAR ENFUNDADAS CON ALEACION DE CIRCONIO |
摘要 |
<p>An array of rods is assembled to form a fuel element for a pressurized water reactor, the rods comprising zirconium alloy sheathed nuclear fuel pellets and containing helium. The helium gas pressure is selected for each rod so that it differs substantially from the helium gas pressure in its closest neighbors. In a preferred arrangement the rods are arranged in a square lattice and the helium gas pressure alternates between a relatively high value and a relatively low value so that each rod has as its closest neighbors up to four rods containing helium gas at the other pressure value.</p> |
