摘要：
Apparatus for improved detection of failed fuel especially in a pressurized water type of nuclear reactor is described. Each fuel rod is provided with a pressure sensitive assembly which responds to perssure changes by rotation of a magnetic element. The fuel rods are housed in an assembly having a removable upper fitting and which allows access through the fitting by a detector to the magnetic element of each fuel rod to sense its radial position and thus its internal pressurization, and by this means the condition of the fuel.
