Abstract

PURPOSE: To reduce the mean density of coolant passing through vent tubes at an accidental time of piping failure, by means of separating the gas and the liquid of the two phases flowed out from a breaking part of the piping, and of reducing the liquid quantity entered into the prenum chamber via vent tubes.
CONSTITUTION: When an accumulated water 71 is present, a height Lc from the floor plate of upper opening ports 61 of vent tubes 8 is made high sufficient to hold the total water flowed out within the drywell on the floor plate in a case when whole of the first coolant which is holded in the reactor vessel, is discharged. In a standard reactor of the thermal output of 3300 MW grade, the quantity of the first coolant is at 350 t, and the area of the floor is 500m2 and when the first coolant is flowed out from 70 atm. into a drywell of one atm., the flowed out water quantity becomes to 350 (1-0.37) = 220.5 t, thereby Lc= 230/500= 0.46, Lc may be specified as 50cm by means of estimating the margin. Accordingly, the materials passing through the vet tube is only steam.
