ABSTRACT:
Handling pool for nuclear fuel, located above the vessel of a pressurized water-nuclear reactor, characterized in that it has, around the vessel cover and the mechanisms surmounting it, a bulkhead, which is generally cylindrical of revolution and is tightly and detachably fixed to the pool bottom. This arrangement makes it possible to keep the pool filled with water outside the bulkhead during reactor operation, so that within the safety enclosure there is a large water reserve on the core, which facilitates its reflooding if there is a fracture to the primary circuit. The still full pool can be used for storing spent fuel.
