METHOD FOR CONTROLLING THE POSITIONS OF NUCLEAR FUEL ASSEMBLIES INSIDE A NUCLEAR REACTOR CORE, AND CORRESPONDING CONTROL ASSEMBLY |
摘要 |
<p>The invention relates to a method for controlling the positions of a plurality of nuclear fuel assemblies (1) relative to an upper core plate (3) in a nuclear reactor core, the method comprising the following steps: choosing a reference point (13) in internals or in a reactor vessel; determining the positions of S-shaped holes in the nuclear fuel assemblies (1) relative to the reference point (13), each S-shaped hole being intended to cooperate with a corresponding centring pin of the upper core plate (3); acquiring the positions of the centring pins of the upper core plate (3) relative to the reference point (13); and comparing the positions of the S-shaped holes and the positions of the pins and deducing therefrom whether the nuclear fuel assemblies (1) are correctly positioned relative to the upper core plate (3).</p> |
