Disclosed is a process for introducing zinc into a water-containing component of the primary system of a nuclear power plant, in particular for preventing the deposition of radioactive cobalt and/or for reducing the possible susceptibility of materials in the component to corrosion. An effective level of zinc is introduced into the component as a dissolved zinc compound which is a zinc complex and/or metal zincate. c

Process for introducing zinc into a water-containing component of the primary system of a nuclear power plant

An apparatus for storing nuclear reactor fuel assemblies in a water pit, includes means for holding an end of a fuel assembly and for transporting the fuel assembly through the water pit, a vessel disposed in the water pit having a closed bottom and an open top in communication with a water space in the water pit forming a vertically elongated well in the vessel for at least partly receiving a fuel assembly, a suction connection in communicaton with the well through the closed bottom of the vessel, a suction pump connected to the suction connection, a shielding container, and a filter disposed in the shielding container and connected to the pump for collecting deposits suctioned from the well.
