A method for testing whether fuel rods of fuel assemblies resting on a working base and under water, of a nuclear reactor are leaking is disclosed. The method includes heating at least one first fuel assembly of a first division of fuel assemblies for driving radioactive fission products out of a defective fuel rod contained in the first fuel assembly. The first fuel assembly is continuously tested by extracting samples of water and continuously degassing the water removed from an area around the first fuel assembly even during the heating resulting in gas. A radioactivity of gaseous fission products released in the gas is continuously recorded. A fuel assembly belonging to a second division of fuel assemblies is heated only if the first fuel assembly belonging to the first division of fuel assemblies has been tested. An apparatus for implementing the method is also disclosed.       Recently Added Patents Method for detecting a malfunction in an automated irrigation system Method and device for multiplexing and mapping services to an OTU Methods and devices for coding and decoding the position of the last significant coefficient Recording user-driven events within a computing system Inhaler Rotary drive device Semiconductor integrated circuit device   Randomly Featured Patents Separating cobs from grain in a corn harvester Segmented photoplethysmographic sensor with universal probe-end Control valve Ceiling panel for an airplane Power converter with desulfation mode Demand control system, demand controller, demand program, and demand controlling method Container Aminocarboxylic acid fluorobutenyl esters High resolution soft x-ray or ion beam lithographic mask Electrical plug safety device © 2006-2008 PatentGenius.
