Condensate treatment system and condensate treatment method

摘要

PROBLEM TO BE SOLVED: To execute by-pass operation of a condensate demineralizer tower in normal time and immediately pass whole condensate flow through the condensate demineralizer tower in emergency such as sea water leakage. SOLUTION: A condensate processing system of a pressurized water reactor is provided with a condensate demineralizing path passing condensate from a condenser 4 through a condensate demineralizing device placing a plurality of condensate demineralizer towers 10 and returning to a steam generator 1 and a bypass path 11 bypassing at least a part of the condensate demineralizer towers 10 and returning to the steam generator 1. In this case, circulation lines 23 and 24 having a capacity capable of simultaneously ensuring minimum flow velocity for the whole condensate demineralizer towers 10 are provided in the condensate processing system and the condensate processing method.
