The feed water distributing system has a consistent feed water distribution when starting up and during a partial load operation with low mechanical loads and has a redundancy of the individual components while maintaining the customary level of reliability in nuclear power plants. Each feed water distributer has exactly one annular main body with an inner channel, at least one fill socket which is fluidically connected to the inner channel via at least one fill opening, and a plurality of outlet nozzles which are fluidically connected to the inner channel. Each of the fill sockets of one feed water distributer is fluidically connected to each outlet nozzle of the feed water distributer. | 2015-04-02 |
