摘要：
A method of operating a nuclear reactor is disclosed. The reactor (1) encloses a core having a plurality of fuel rods (9). Each fuel rod (9) includes a cladding and fuel pellets of a nuclear fuel. The fuel pellets are arranged in an inner space of the cladding leaving a free volume comprising an upper plenum, a lower plenum and a pellet-cladding gap. The reactor is operated at a normal power and a normal inlet sub-cooling during a normal state. The reactor is monitored for detecting a defect on the cladding of any of the fuel rods. The operation of the reactor is changed to a particular state after detecting such a defect. The particular state permits an increase of the free volume in the defect fuel rod. The reactor is operated at the particular state during a limited time period, after which the reactor is operated at the normal state.
摘要（中）：
公开了一种操作核反应堆的方法。 反应器（1）包围具有多个燃料棒（9）的芯体。 每个燃料棒（9）包括核燃料的包层和燃料颗粒。 燃料颗粒被布置在包层的内部空间中，留下一个自由体积，包括上部气室，下部气室和颗粒包层间隙。 在正常状态下，反应器以正常功率和正常的入口副冷却运行。 监测反应器以检测任何燃料棒的包层上的缺陷。 在检测到这样的缺陷之后，反应器的操作变为特定状态。 该特定状态允许增加缺陷燃料棒中的自由体积。 反应器在特定状态下在有限的时间内运行，此后反应器在正常状态下运行。
