Abstract
A device for detecting sealing defects and for measuring the leakage rate of gaskets placed in parallel relationship on the lateral surface of a gate separating the compartments of a storage pool for nuclear fuel elements has a small volume of free space between the gaskets. This volume is connected by means of a tube with two leakage level detectors placed at different levels which emit a signal when a predetermined water level is attained in the tight volume.
Claims12
An apparatus for monitoring and measuring the leakage of water between adjacent compartments of a water basin, comprising:
- a dike comprising a gate for closing an opening between two adjacent compartments of said water basin;
- a plurality of gaskets extending along a lateral surface of said gate;
- a raised rib extending along a wall of said opening, wherein said gaskets, said rib and said wall comprise a free space when said dike is in a closed position;
- means for detecting the level of water in said free space, said means for detecting the level of water in said free space providing a calibration reference volume;
- and
- said detecting means generating electrical signals providing an indication of the rate of water leakage into said free space.
