REQUEST FOR ADDITIONAL INFORMATION DAVIS-BESSE NUCLEAR POWER STATION DOCKET NO. 50-346 1.
The proposed backup boron precipitation flushing emergency core cooling system (ECCS) mode would involve ECCS flow going from the suction of the low pressure injection pumps through those pumps to the suction of the high pressure injection (HPI) pumps through a crossover line, through the HPI pumps to the pressurizer spray to the pressurizer, and finally to the reactor coolant system (RCS) hot leg through the pressurizer (J-shaped) surge line. Using spray, it takes some time to fill the pressurizer and its associated surge line sufficiently to inject into the RCS hot leg. Please provide additional information to show that this backup boron flushing path will be available when and if it is needed.
